[0007] overview

[0067] This disclosure relates to personal protective equipment in general, and more specifically to face shields. Simple cloth masks, described in the Journal of the American Medical Association as "a fake handkerchief wrapped around a doctor's face," were primarily designed to protect patients from what is called "droplet transmission"—invisible, potentially virus- and bacteria-transmitting moisture emitted from a doctor's mouth and nose. Over the past 100 years, personal protective equipment (PPE) masks have become standard for healthcare professionals in the workplace. However, as seen during the 1918 Spanish flu pandemic, when nurses and doctors infected 22 million Americans (675,000 of whom died), cloth masks offered limited protection against truly aggressive viruses, including COVID-19. Based on the distribution of past pandemic vaccines and the 300% population increase since previous pandemics, global vaccination will take time, experts point out that "there is typically a seven-year time lag before developing countries can access new vaccines." Furthermore, even vaccinated individuals may still need to wear masks as they can carry and spread the virus. "

[0068] This is because masks reduce infection by decreasing the number of infectious particles spread by the mask wearer (known as "source control"). In the case of COVID-19, Dr. Chiu and Dr. Fauci have warned of mutations in the spike protein that could interfere with the effectiveness of vaccines, and that this could also pose a threat to COVID-19 antibody drugs.

[0069] In some cases, variants of COVID-19 are more infectious than COVID-19 itself. Therefore, the availability of functional kits that improve the filtration and sealing capabilities of masks, and higher-quality masks that provide a more comfortable fit, is becoming increasingly important. This specification describes devices, systems, and / or kits that can advantageously convert PPE medical masks to improve filtration, comfort, and / or filter protection, and / or provide an airtight seal. High-quality masks and / or functional conversion kits are crucial in the fight against viruses and / or viral variants because they can advantageously reduce infection and / or improve filtration and / or comfort.

[0070] Because facial features vary from person to person, some PPE masks currently on the market cannot be customized to create an optimal seal between the wearer's face and the mask, resulting in gaps. Since air moves where there is least resistance, air tends to pass through open gaps, as opposed to the mask's filtration area. Some medical masks have a filtration rate of over 90% for viruses, including COVID-19. However, if the mask's seal is not optimal, filtration performance can be compromised regardless of the filtration rate.

[0071] "Surgical masks do not prevent disease," says Dr. William Schaffner, medical director of the National Infectious Diseases Foundation. Rather, he explains that such masks are often manufactured from loose, flat material and do not fit the face properly. This means that gaps can form around the cheeks and corners of the mouth, allowing air to easily enter and exit. Furthermore, according to May Chu, clinical professor of epidemiology at the University of Colorado School of Public Health, surgical masks can filter about 70% of the outside air. Meanwhile, about 30% reaches the nose and mouth directly on either side of the mask. In other words, surgical masks protect about 70% of the wearer.

[0072] Furthermore, Dr. Schaffner stated that N95 respirators are more effective and can filter out 95% of particles. However, he pointed out that non-healthcare workers using this type of mask are less likely to wear it correctly, resulting in a poor seal around the nose and mouth. In addition, N95 masks make breathing more difficult for the wearer and increase discomfort while wearing them. In fact, the U.S. Food and Drug Administration (FDA) advises people with chronic respiratory, heart, or other medical conditions to consult with a healthcare provider before using an N95 face mask. Moreover, N95 masks are not designed for people with facial hair or for children.

[0073] A study at Duke University found that KN-95 and N95 masks were the most effective face masks, while surgical masks were the second most effective. The main material for N95, FFP, KN95, and surgical masks is meltblown polypropylene. The primary reason surgical masks were ranked second is their loosely manufactured, flat design, lacking the rigid layers of material that create a tight seal around the wearer's mouth and nose. Compared to surgical masks, N-95 masks can cost 1500% to 3000% more due to increased manufacturing requirements.

[0074] The embodiments described herein can advantageously convert loose and / or flat surgical masks to be molded to a desired tight shape (e.g., the shape of an N-95 face mask). Furthermore, surgical masks and / or other masks can be customized to the user's facial features, thereby increasing the mask's airtightness and making it more effective than most masks. Mask conversion can reduce the difficulty of breathing due to the molding material and associated costs. In addition, the supply of N-95 masks may be low in some cases due to limitations in machine utilization, high manufacturing costs, and / or demand. On the other hand, the supply of surgical masks may be high due to the lower cost of manufacturing machinery.

[0075] Experts have recommended that President Biden's COVID-19 task force also provide all Americans with high-filtration masks and several kits that "assist in wearing other masks, enhance comfort, are washable, reusable, fit better, and allow the use of other filters in higher-risk situations." Today, PPE challenges facing the world include shortages of meltblown fabric (a key component of surgical masks, N95 masks, and FFP masks), a lack of ergonomic comfort, limited conversion capability, and unreliable quality assurance. The face masks and / or face mask conversion systems described herein can significantly improve quality assurance, comfort, and conversion capability. The public PPE market is a new area for mask manufacturers.

[0076] Meltblown masks generally lack a cushioned, airtight seal. Consequently, larger straps and / or more material covering the face may be generally required to form a partial seal. Embodiments described herein advantageously provide one or more air cushion seals (e.g., 16 air cushion seals in some embodiments) that can provide pillow-like comfort. The air cushions conform to any person's face, enhancing comfort and airtightness. They are broadly categorized into three types: masks, face shields, and goggles. Surgical masks and N95 respirators are two well-known types of medical masks. Surgical masks are made from disposable, fluid-resistant material and can protect the wearer from large forward splashes, droplets, or sprays of hazardous liquids. Originally designed for sterile operating room environments, surgeons are primarily concerned with forward airflow, as opposed to lateral airflow or the inhalation of filtered air in an operating room. New research and expert studies have shown that wearing a surgical mask in a non-sterile room containing viral aerosols offers little protection against inhalation of these aerosols.

[0077] Surgical masks can offer some protection to others from the wearer's respiratory exhalations. However, surgical masks may not adequately protect against small airborne aerosols, at least in part, because they fit somewhat loosely and / or do not form a tight seal with the wearer's face. N95 respirators are sometimes made from disposable materials that are more airtight than surgical masks and can filter smaller airborne particles. When properly fitted, respirators offer better protection from airborne viral particles than surgical masks. However, respirators may obstruct the wearer's breathing and may not be suitable for people with chronic respiratory, heart, or other medical conditions. Furthermore, N95 respirators are designed for short-term use by professional healthcare workers and hazardous workers, and should be worn for several hours at a time in an extremely tight fit, as opposed to prolonged use (e.g., all day). Additionally, during pandemics, the supply of surgical masks and N95 respirators may be insufficient and limited to healthcare workers only. The general public may have to rely on cloth masks, but these are considerably less effective than surgical masks or N95 respirators at filtering virus-containing aerosols. Furthermore, another drawback of face masks is that some accumulate viral droplets on the filter, increasing the likelihood of contamination when the filter is touched. In addition, none of the aforementioned face masks offer eye protection, so goggles must be worn in addition to the mask.

[0078] Conventional face shields are not porous, so they can effectively block droplets and aerosols that spread from directly in front of or behind the shield. However, some face shields cannot prevent contaminated air from moving around the shield or entering or leaving the wearer's face area from above, below, or the sides. As a result, conventional face shields are generally not used alone and are often worn in conjunction with masks or goggles.

[0079] Multiple barriers may be needed to resist a stream of contaminated air. However, some surgical masks, N-95 respirators, and / or face shields are designed to provide only a single barrier. Furthermore, such protective equipment generally does not include sensors for tracking movement data and / or recording metrics for individual wearers or groups of wearers, much less providing communication between users.

[0080] Embodiments described herein provide mask conversions and / or mask conversion kits that can advantageously improve mask duration (e.g., by about 300% to 900%) compared to unconverted masks. In some cases, the durability and / or duration of the mask can be improved by protecting the inner and / or outer center of the mask filtration area and / or by using a highly airtight cushion seal. Generally, face masks (including meltblown masks) can deteriorate rapidly when exposed to contamination from moisture emitted from the user's mouth, which can accumulate particularly near the center of the mask. In some cases, the mask needs to be replaced daily. Some embodiments described herein can include providing protective inner and / or outer barriers that can prevent user and / or environmental contamination of the mask filtration area. In some embodiments, the protective seal and / or barrier can allow most of the air (e.g., from the user's mouth and / or nose) to enter and / or exit the mask's filtration area, as opposed to gaps that may form around an unfiltered mask.

[0081] While meltblown masks have high PPE quality assurance regarding filtration performance, they may generally have lower airtight sealing capability, ergonomic comfort, and / or protective performance of the mask material. Some embodiments described herein include face masks having multiple (e.g., two) composite seal filtration units and / or oxygen filtration enhancement units. Such face masks can significantly improve the air-sealing effect and comfort of various masks, including N95, FFP, KN95, and surgical meltblown masks, resulting in higher assurance.

[0082] Some embodiments involve transforming and / or modifying various filtering sheets and / or elements, particularly cloth, FFP, KN95 and / or N95 face masks, into more effective, airtight, breathable, body-fitting, and / or comfortable face shields. The term “filtering sheet” is used herein in its plain and ordinary sense and may refer to any mask (including face masks), cloth, sheet, wrap, cover, pad, and / or similar device configured to at least partially block, obstruct, and / or filter various gases, liquids, and / or solids on or near the user’s face and / or head. Filtering sheets may consist of a variety of materials, including cloth, woven and / or nonwoven fabrics, polyester, nylon, and / or natural and / or synthetic fibers. In some embodiments, filtering sheets may be generally flat and / or at least partially flexible to conform to the user’s face and / or components of the face assembly. Filtering sheets may include pleats, folds, stitches, clips, cells, and / or other mechanisms. In some embodiments, the filtering element may include one or more user attachment mechanisms (e.g., ear loops). Conversion of such filtering elements may advantageously include conversion devices that can be manufactured using available injection molding techniques and / or recycled plastics. The filtering sheet may include any devices and / or materials configured to be positioned and / or filter between components of a facial covering assembly, as described herein.

[0083] Examples of facial mask conversion systems and devices include an integrated multi-airtight cushion seal, one or more airflow filtration enhancement units with an inner protective seal, a mask molding frame and / or various attachments, a primary attachment secondary seal clip triple filtration unit, a reusable ear frame, an adjustable ear loop unit, and / or eyewear connection.

[0084] The face masks and / or converted face masks described herein may be advantageously configured to reduce airflow around the PPE mask by using a thermodynamic airflow model. Such masks can provide a greater vacuum inside the mask than the ambient and / or outside air inside the mask. Multi-air seal designs, such as those described herein, may consist of one or more cellular air pockets separated by rib partitions that can conform to facial features for an improved airtight fit. Furthermore, some embodiments may provide an airflow filtration-enhanced base unit for sealing the air. The face covering assemblies described herein may be configured to provide a reverse-acting seal over at least a portion of the user's facial area. In some embodiments, the face covering assembly (including the converted face mask) may be configured to conform effectively to the user's face. The face covering may include one or more air pockets (e.g., 16 air pockets separated by columns and / or ribs) to enable the face covering to form an airtight seal over the user's face.

[0085] Certain drawbacks associated with some face masks, including surgical-type masks, include the possibility that at least a portion of the face mask may come into contact with and / or be positioned close to the user's mouth and / or nose during use, and / or that various gaps may be created between the user's face and the mask through which air can escape. Some face masks, including M95 masks, can be manufactured through a mechanical process that forms a conical shape to create a separation between the face mask and the user's face in order to improve the seal between the face mask and the user's face. However, such masks are not only costly but also do not completely seal the user's face.

[0086] Some embodiments described herein can utilize a frame and / or associated system, which, when used in combination with various face masks, can effectively create separation between the face mask and the user's face without requiring the face mask to have a pre-formed conical and / or similar shape. Furthermore, the frame and / or associated system can effectively improve the seal to the user's face compared to a mask used alone.

[0087] Figures 1A and 1B show a user wearing an exemplary face covering assembly 100 configured to protect and / or cover at least a portion of the user's facial area (which may include at least a portion of the vicinity area including the user's mouth, nose, eyes, and / or the user's neck and / or other parts of the user's head). The face covering assembly 100 described herein may consist of a frame 102 (which may consist of multiple components), one or more filtering portions 104, and / or one or more mounting mechanisms 106 connected to attach and / or hold the face covering assembly 100 in a desired position on the user's facial area. In some embodiments, the mounting mechanism 106 may include flexible and / or elastic straps that form loops connected to fit at least partially around the user's ears. However, the mounting mechanism 106 may have any of a variety of forms, including one or more generally rigid and / or flexible arms.

[0088] In some embodiments, the frame 102 may be configured to maintain at least partial separation between the user's nose and / or mouth and one or more filtering portions 104. The frame 102 may be configured to position the frame 102 and / or one or more filtering portions 104 to cover at least a portion of the user's nose and / or mouth while maintaining a seal (e.g., an airtight seal) around the user's nose and / or mouth. In some embodiments, the frame 102 may be configured to hold one or more filtering portions 104 in an orientation generally parallel to the user's face and / or mouth.

[0089] One or more filtering sections 104 may be at least partially composed of one or more materials configured to filter water droplets and / or various contaminants. For example, one or more filtering sections 104 may be at least partially composed of meltblown and / or polypropylene material and / or fibers. In some embodiments, the frame 102 may be configured to tighten one or more filtering sections 104 to maximize the effect of the one or more filtering sections 104. The frame 102 may further be configured to increase the separation between one or more filtering sections 104 (which may include a face mask that can be used independently of the frame 102) and / or the user's mouth and / or nose. For example, a face mask used alone may have 30-60% contact between the face mask and the user's face, which may limit the amount of material available for filtering. Furthermore, increased contact between the face mask and the user's face may increase the rate of decomposition of the face mask, potentially leading to material degradation, moisture accumulation, and / or odor. In contrast, the facial covering assembly 100 can have less than approximately 10 percent contact between one or more filtering portions 104 (e.g., face masks) and the user's face. For example, one or more filtering portions 104 may be configured to contact the user's face only at the inner edges of the frame 102 and / or inner frame. In this way, one or more filtering portions 104 can filter air more effectively and / or decompose more slowly than a face mask used independently.

[0090] Figures 2A and 2B illustrate exemplary facial covering conversion systems 200. Figure 2A provides an exploded view of the facial covering conversion system 200, and Figure 2B provides an assembled view of the facial covering assembly 200. Some facial covering assemblies 200 may utilize independent and / or separate face masks 204 and / or filtering devices. A suitable face mask 204 may include a surgical mask, among many others. In some embodiments, the face mask 204 may include one or more attachment mechanisms 206 (e.g., elastic bands) for attaching to the user's face and / or head (e.g., the user's ears). In some embodiments, multiple face masks 204 and / or a portion of multiple face masks 204 may be incorporated into the facial covering assembly 200.

[0091] The facial covering conversion system 200 can constitute a frame, which may include an inner frame 202 (i.e., an inner frame portion) and / or an outer frame 203 (i.e., an outer frame portion). The inner frame 202 may be configured to function as an airflow filtration enhancement unit, and / or the outer frame 203 may be configured to function as an airtight triple filtration seal. In some embodiments, the face mask 204 may be configured to be at least partially positioned between the inner frame 202 and the outer frame 203. The inner frame 202 and / or the outer frame 203 may be configured to provide the face mask 204 with general rigidity and / or stable support. For example, the inner frame 202 and / or the outer frame 203 may be at least partially made of plastic, metal, and / or other generally rigid materials. In some embodiments, the inner frame 202 and / or outer frame 203 may be configured to maintain at least partial separation between at least a portion of the user's face (e.g., the user's nose and / or mouth) and at least a portion of the face mask 204 (e.g., the central portion of the face mask 204).

[0092] In some embodiments, the inner frame 202 may comprise a first sealing portion 212 and / or a first conical portion 213. The first sealing portion 212 may comprise a generally elliptical frame configured to form a complete ellipse (e.g., circular) and / or loop surrounding at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth). In some embodiments, the first sealing portion 212 may be configured to completely surround at least the user's mouth and / or nose. The first sealing portion 212 may be configured to facilitate and / or form a complete seal and / or airtight seal around at least a portion of the user's face.

[0093] The first sealing portion 212 may have any suitable width and / or may be configured to extend approximately away from the user's face when the inner frame 202 is placed on the user's face. For example, the first sealing portion 212 may consist of an inner edge 215 and / or an outer edge 216, and / or its width may represent the distance between the inner edge 215 and the outer edge 216. The inner edge 215 may be configured to be closer to the user's face than the outer edge 216 when the inner frame 202 is placed on the user's face.

[0094] The first conical portion 213 may extend from at least a portion of the first sealing portion 212 and / or may be configured to be attached to at least a portion of the first sealing portion 212. The first conical portion 213 may have a generally convex shape when viewed from the outside and / or may be configured to be away from the user's face when the inner frame 202 is placed on the user's face. The first conical portion 213 may consist of the inner frame 202, the first sealing portion 212, the first conical portion 213, and / or one or more openings 217 connected to allow airflow through one or more openings 217. The first conical portion 213 may consist of a network of one or more attachments 218 connected to extend between the first sealing portion 212 and the central portion 219 of the first conical portion 213. The first conical portion 213 is shown in Figure 2A to have four attachments 218 that form four openings 217, but the first conical portion 213 can consist of any number of attachments 218.

[0095] In some embodiments, the central portion 219 may be configured to be positioned at least partially in front of at least a portion of the user's mouth and / or nose when the inner frame 202 is positioned on the user's face. The central portion 219 may have any suitable shape and / or may consist of generally oval, semi-oval, and / or other shapes. Advantageously, the central portion 219 may be configured to be positioned in front of and / or opposite the user's mouth and / or nose to prevent water droplets from the user's mouth and / or nose from contacting and / or saturating the face mask 204. In some cases, attenuation and / or saturation of the face mask 204 may reduce the filtering effect of the face mask 204.

[0096] The inner frame 202 and / or the first sealing portion 212 may include one or more mounting mechanisms, which may include an outer frame mounting mechanism 220 and / or a user engagement mounting mechanism 221. The outer frame mounting mechanism 220 may be configured to mate with a corresponding inner frame mounting mechanism 240 in the outer frame 203. For example, the outer frame mounting mechanism 220 may include notches, pegs, hooks, and / or similar mechanisms configured to mate with the inner frame mounting mechanism 240. The user engagement mounting mechanism 221 may be configured to mate with a corresponding user engagement mechanism, which may include various straps, arms, and / or other mechanisms configured to form attachments to the user's ears and / or other parts of the user's head.

[0097] In some embodiments, the inner frame 202 and / or the first sealing portion 212 may constitute an eyewear mount 222 located above or near the first sealing portion 212. For example, the eyewear mount 222 may be configured to be located at or near the highest point of the inner frame 202 when the inner frame 202 is placed on the user's face. The eyewear mount 222 may be configured to mate with various eyewear and / or eyewear mounting mechanisms. For example, the eyewear mount 222 may include one or more pegs, clips, notches, and / or other mechanisms configured to receive eyewear and / or eyewear clips and / or to form attachments with eyewear and / or eyewear clips.

[0098] The inner frame 202 may be configured to reduce facial contact between the face mask 204 and the user's face by approximately 90 percent, and / or to increase the filtration surface area of ​​the face mask 204 by 400 percent or more.

[0099] The outer frame 203 may include a second sealing portion 232 and / or a second conical portion 233. The second sealing portion 232 may be configured to form a complete ellipse (e.g., a circle) and / or loop surrounding at least a portion of the face mask 204 and / or the inner frame 202. In some embodiments, the second sealing portion 232 may be configured to completely surround at least the central portion 219 and / or the first conical portion 213. The second sealing portion 232 may be configured to facilitate and / or form a complete seal and / or airtight seal around at least a portion of the user's face.

[0100] The second conical portion 233 may extend from at least a portion of the second sealing portion 232 and / or be configured to be attached to at least a portion of the second sealing portion 232. The second conical portion 233 may be configured to approximate and / or match the curvature and / or shape of the first conical portion 213 such that the first conical portion 213 and the second conical portion 233 are located close to each other along the entire length of the second conical portion 233 when the inner frame 202 is fitted onto the outer frame 203. For example, the second conical portion 233 may be configured to extend away from the user's face when the outer frame 203 is placed over the user's face. The second conical portion 233 may include one or more openings 237 connected to the outer frame 203, the second sealing portion 232, the second conical portion 233, and / or one or more openings 237 to allow airflow through the openings 237. One or more openings 237 of the second conical portion 233 may be the same size as one or more openings of the first conical portion 213, and / or may be configured to be in line with one or more openings of the first conical portion 213 when the inner frame 202 is fitted into the outer frame 203. The second conical portion 233 may consist of a network of one or more attachments 238 connected to extend between the second sealing portion 232 and the central portion 239 of the second conical portion 233. One or more attachments 238 may coincide with and / or approximate one or more attachments 218 of the first conical portion 213. The second conical portion 233 is shown in Figure 2A with three attachments 238 forming three openings 237, but the second conical portion 233 can consist of any number of attachments 238.

[0101] In some embodiments, the central portion 239 may be configured to be at least partially positioned in front of at least a portion of the user's mouth and / or nose when the outer frame 203 is placed on the user's face. The central portion 239 may have any suitable shape and / or may consist of a generally oval, semi-oval, and / or other shape. In some embodiments, the central portion 239 of the outer frame 203 may be similar in size and / or shape to the central portion 219 of the inner frame 202. The central portion 239 may be advantageously configured to be positioned in front of and / or opposite the user's mouth and / or nose to prevent contact between at least a portion of the face mask 204 (e.g., the portion of the face mask 204 that is positioned closest to the user's mouth and / or nose when worn by the user) and a potentially contaminated surface (e.g., when the face covering conversion system 200 is removed from the user's face and / or placed on a surface).

[0102] The outer frame 203 and / or the second sealing portion 232 may include one or more mounting mechanisms, which may include an inner frame mounting mechanism 240. The inner frame mounting mechanism 240 may be configured to mate with a corresponding outer frame mounting mechanism 220 of the inner frame 202. For example, the inner frame mounting mechanism 240 may include notches, pegs, hooks, and / or similar mechanisms configured to mate with the outer frame mounting mechanism 220, and these notches, pegs, hooks, and / or similar mechanisms may include corresponding notches, pegs, hooks, and / or similar mechanisms. The inner frame mounting mechanism 240 may include a curved clip provided around a generally elliptical and / or rectangular opening that extends substantially perpendicularly from the second sealing portion 232 and / or through which the outer frame mounting mechanism 220 can pass. The outer frame mounting mechanism 220 may have a generally rectangular notch that extends away from the first sealing portion 212 and / or forms a lip configured to catch through the opening of the inner frame mounting mechanism 240. The face mask can be sandwiched between the inner frame mounting mechanism 240 and the outer frame mounting mechanism 220.

[0103] The outer frame 203 may be configured to form a second seal (where the inner frame 202 and / or cushioning element 205 form a first seal) and / or multiple filtration regions to provide approximately 95–99 percent filtered airflow through the outer frame 203.

[0104] The facial covering conversion system 200 may further include a cushioning element 205 configured to contact at least a portion of the user's face when used by the user. The cushioning element 205 may generally be an oval pad, pillow, cushion, brace, guard, and / or other user-facing element adapted to contact the user's face. In some embodiments, the cushioning element 205 may have a generally soft and / or flexible structure, but alternatively, the cushioning element 205 may have a generally firm and / or rigid structure. The cushioning element 205 may be configured to form a complete oval (e.g., circular) and / or loop surrounding at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth), and / or to approximate and / or match the shape and / or size of the first sealing portion 212 of the inner frame 202. In some embodiments, the cushioning element 205 may be configured to completely surround at least the user's mouth and / or nose. The cushioning element 205 may be configured to facilitate and / or create a complete and / or airtight seal around at least a portion of the user's face. In some embodiments, the cushioning element 205 may be configured to bond to and / or otherwise contact the inner frame 202.

[0105] In some embodiments, the cushion element 205 may consist of a plurality (e.g., 10) cushion pillows and / or sections separated by ribs and / or partitions. The plurality of cushion sections may be configured to independently conform to the user's face in order to improve sealing around at least a portion of the user's face. The cushion element 205 may be at least partially constructed of a generally flexible and / or elastic material in order to allow the cushion element 205 to conform to the shape of the user's face while forming an airtight seal between the cushion element 205 and the user's face. The cushion element 205 may be configured to be permanently or removablely attached to the inner frame 202 (e.g., using hook-and-loop fasteners and / or other mounting mechanisms and / or materials).

[0106] Figure 2B shows an assembled face covering conversion system 200 with an inner frame mounting mechanism 240 fitted to an outer frame mounting mechanism 220. In some embodiments, at least a portion of the face mask 204 may be positioned at least partially between the inner frame mounting mechanism 240 and the outer frame mounting mechanism 220 when the inner frame mounting mechanism 240 is fitted to the outer frame mounting mechanism 220, as shown in Figure 2B. As shown in Figure 2B, one or more portions of the face mask 204 may be exposed through one or more openings 237 in the outer frame 203 to allow airflow through the filtering mechanism of the face mask 204.

[0107] Figure 3A shows an example of an N-95 1860 face mask 304 that can be converted into a conversion facial covering assembly 300, as shown in Figure 3B. The dashed circle 301 in Figure 3A indicates a portion of the face mask 304 that is generally located in front of the user's mouth and / or nose and / or is likely to come into contact with the user's mouth and / or nose and / or is likely to become saturated with moisture. Furthermore, the face mask 304 itself may be prone to air leakage at its edges. When used independently of the other elements of the facial conversion system 300, the face mask 304 may have a generally soft and / or flexible structure so that it is easily crushed when pressure is applied and may come into contact with the user's mouth and / or nose.

[0108] As shown in Figure 3B, the converted face covering assembly 300 may include a frame 302 and / or cushioning elements (not shown) which can be configured to form and / or maintain a seal between the converted face covering assembly 300 and the user's face. The frame 302 may include an inner frame (not shown in Figure 3B, see Figure 2A) and / or an outer frame. In some embodiments, the frame 302 may be configured to prevent contact between a portion of the face mask 304 identified by the dashed circle 301 and a contaminated surface. The frame 302 and / or cushioning elements may be configured to form and / or maintain separation between the portion of the face mask 304 identified by the dashed circle 301 and at least a portion of the user's face (e.g., the user's mouth and / or nose).

[0109] Figure 4A shows an exemplary surgical face mask 404 that can be converted into a conversion facial covering assembly 400, as shown in Figure 4B. The dashed circle 401 in Figure 4A identifies portions of the face mask 404 that are likely to be positioned in front of the user's mouth and / or nose, and / or that may come into contact with the user's mouth and / or nose, and / or that may become saturated with moisture. Furthermore, the face mask 404 itself may be prone to air leakage at its edges.

[0110] As shown in Figure 4B, the converted face covering assembly 400 may include a frame 402 and / or cushioning elements (not shown) that can be connected to form and / or maintain a seal between the converted face covering assembly 400 and the user's face. The frame 402 may include an inner frame (not shown in Figure 4B; see Figure 2A) and / or an outer frame. In some embodiments, the frame 402 may be configured to prevent contact between a portion of the face mask 404 identified by the dashed circle 401 and a contaminated surface. The frame 402 and / or cushioning elements may be configured to form and / or maintain separation between the portion of the face mask 404 identified by the dashed circle 401 and at least a portion of the user's face (e.g., the user's mouth and / or nose).

[0111] Figure 5A shows an example of a KN95 / FFP face mask 504, which can be converted into a conversion face cover assembly 500, as shown in Figure 5B. The dashed circle 501 in Figure 5A indicates a portion of the face mask 504 that is likely to be positioned in front of the user's mouth and / or nose, and / or in contact with the user's mouth and / or nose, and / or is particularly likely to become saturated with moisture. Furthermore, the face mask 504 itself may be prone to air leakage at its edges.

[0112] As shown in Figure 5B, the converted face covering assembly 500 may include a frame 502 and / or cushioning elements (not shown) that can be connected to form and / or maintain a seal between the converted face covering assembly 500 and the user's face. The frame 502 may include an inner frame (not shown in Figure 5B, see Figure 2A) and / or an outer frame. In some embodiments, the frame 502 may be configured to prevent contact between a portion of the face mask 504 identified by the dashed circle 501 and a contaminated surface. The frame 502 and / or cushioning elements may be configured to form and / or maintain separation between the portion of the face mask 504 identified by the dashed circle 501 and at least a portion of the user's face (e.g., the user's mouth and / or nose).

[0113] Figure 6A shows an exemplary cloth face mask 604 that can be converted into the converted face covering assembly 600, as shown in Figure 6B. The dashed circle 601 in Figure 6A identifies portions of the face mask 604 that are likely to be positioned in front of the user's mouth and / or nose, and / or that may come into contact with the user's mouth and / or nose, and / or that may become saturated with moisture. Furthermore, the face mask 604 may, by itself, be prone to air leakage at the edges of the face mask 604.

[0114] As shown in Figure 6B, the converted face covering assembly 600 may include a frame 602 and / or cushioning elements (not shown) that can be connected to form and / or maintain a seal between the converted face covering assembly 600 and the user's face.

[0165] The first sealing portion 4112 may have any suitable width and / or may be configured to extend generally away from the user's face when the inner frame 4102 is placed on the user's face. For example, the first sealing portion 4112 may consist of an inner edge 4115 and / or an outer edge 4116, and / or the width may represent the distance between the inner edge 4115 and the outer edge 4116. The inner edge 4115 may be configured to be closer to the user's face than the outer edge 4116 when the inner frame 4102 is placed on the user's face.

[0166] The shaper 4113 may extend from at least a portion of the first sealing portion 4112 and / or may be configured to be attached to at least a portion of the first sealing portion 4112. The shaper 4113 may have a generally convex shape when viewed from the outside and / or may be configured to extend away from the user's face when the inner frame 4102 is positioned on the user's face. The shaper 4113 may consist of one or more openings 4117 provided to allow airflow through the inner frame 4102, the first sealing portion 4112, and / or the shaper 4113. The shaper 4113 may consist of a network of one or more attachments 4118 connected to extend between the first sealing portion 4112 and the intermediate portion 4119 of the shaper 4113. The shaper 4113 is shown as a rhombus in Figure 41A, but the shaper 4113 may have any shape and / or be composed of any number of attachments 4118. In some embodiments, the shaper 4113 may have one or more contact points 4128 with the first sealing portion 4112. Although the shaper 4113 is shown in Figure 41 having two contact points 4128 on generally opposing sides of the first sealing portion 4112, the shaper 4113 may have any number of contact points 4128. Furthermore, although the shaper 4113 has a generally rhombus shape in Figure 41, the shaper 4113 may have other shapes. The shaper 4113 may include one or more attachments 4118 extending around one or more openings 4117 of the shaper 4113. In some embodiments, one or more openings 4117 may have a generally triangular shape as shown.

[0167] In some embodiments, the central portion 4119 may be configured to be positioned at least partially in front of at least a portion of the user's mouth and / or nose when the inner frame 4102 is positioned on the user's face. The central portion 4119 may have any suitable shape and / or be composed of a generally triangular and / or other shape. Advantageously, the central portion 4119 may be configured to be positioned in front of and / or opposite the user's mouth and / or nose to prevent water droplets from the user's mouth and / or nose from contacting and / or saturating the filtering element 4104. In some cases, attenuation and / or saturation of the filtering element 4104 may reduce the effectiveness of the filtering element 4104 in providing filtration.

[0168] The inner frame 4102 and / or the first sealing portion 4112 may include one or more mounting mechanisms, which may include an outer frame mounting mechanism 4120 and / or a user engagement mounting mechanism 4121. The outer frame mounting mechanism 4120 may be configured to mate with a corresponding inner frame mounting mechanism 4140 on the outer frame 4103. For example, the outer frame mounting mechanism 4120 may consist of notches, pegs, hooks, and / or similar mechanisms adapted to mate with the inner frame mounting mechanism 4140. The user engagement mounting mechanism 4121 may be configured to mate with a corresponding user engagement mechanism, which may be configured to form attachments to the user's ears and / or other parts of the user's head, and may include various straps, arms, and / or other mechanisms.

[0169] In some embodiments, the inner frame 4102 and / or the first sealing portion 4112 may constitute an eyewear mount 4122 that can be located above or near the first sealing portion 4112.

The eyewear mount 4122 may be configured to mate with various eyewear and / or eyewear mounting mechanisms. For example, the eyewear mount 4122 may include one or more pegs, clips, notches, and / or other mechanisms configured to receive and / or form an attachment with eyewear and / or eyewear clips.

[0170] The inner frame 4102 may be configured to reduce facial contact between the filtering element 4104 and the user's face by approximately 90 percent, and / or to increase the filtering surface area of ​​the filtering element 4104 by 500 percent or more.

[0171] The outer frame 4103 may include a second sealing portion 4132. The second sealing portion 4132 may be configured to form a complete ellipse (e.g., a circle) and / or loop surrounding at least a portion of the filtering element 4104 and / or the inner frame 4102. In some embodiments, the second sealing portion 4132 may be configured to completely surround at least the central portion 4119 and / or the shaper 4113. The second sealing portion 4132 may be configured to facilitate and / or form a complete seal and / or airtight seal around at least a portion of the user's face. The second sealing portion 4132 may consist of a frame that forms a complete ellipse around a generally elliptical opening 4137 that penetrates the second sealing portion 4132.

[0172] The outer frame 4103 and / or the second sealing portion 4132 may include one or more mounting mechanisms, which may include an inner frame mounting mechanism 4140. The inner frame mounting mechanism 4140 may be configured to mate with a corresponding outer frame mounting mechanism 4120 in the inner frame 4102. For example, the inner frame mounting mechanism 4140 may consist of notches, pegs, hooks, and / or similar mechanisms connected to mate with the outer frame mounting mechanism 4120.

[0173] The outer frame 4103 may be configured to form a second seal (where the inner frame 4102 and / or cushioning element 4105 form a first seal) and / or multiple filtration regions that provide approximately 95–99 percent filtered airflow through the outer frame 4103.

[0174] The assembly 4100 may further include a cushioning element 4105 configured to contact at least a portion of the user's face when used by the user. The cushioning element 4105 may be configured to form a complete ellipse (e.g., circular) and / or loop around at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth), and / or to approximate and / or match the shape and / or size of the first sealing portion 4112 of the inner frame 4102. In some embodiments, the cushioning element 4105 may be configured to completely surround at least the user's mouth and / or nose. The cushioning element 4105 may be configured to facilitate and / or create a complete and / or airtight seal around at least a portion of the user's face.

[0175] In some embodiments, the cushion element 4105 may consist of a plurality (e.g., 10) cushion pillows and / or portions separated by ribs and / or partitions. The plurality of cushion portions may be configured to conform independently to the user's face in order to improve sealing around at least a portion of the user's face. The cushion element 4105 may be made of a material that is at least partially generally flexible and / or elastic in order to allow the cushion element 4105 to conform to the shape of the user's face while forming an airtight seal between the cushion element 4105 and the user's face. The cushion element 4105 may be configured to be permanently or removablely attached to the inner frame 4102 (e.g., using hook-and-loop fasteners and / or other mounting mechanisms and / or materials).

[0176] Figures 42A and 42B show an assembled face covering assembly 4200 according to one or more embodiments. Figure 42A provides a front view of the assembly 4200, and Figure 42B provides a perspective view of the assembly 4200. In some embodiments, the assembly 4200 may include an inner frame 4202, an outer frame 4203, and / or a cushioning element 4205. The assembly 4200 can be used in combination with one or more filtering elements (not shown). For example, one or more filtering elements (e.g., a face mask) may be at least partially positioned between the inner frame 4202 and the outer frame 4203, and / or at least partially cover the shaper 4213 of the inner frame 4202. The inner frame mounting mechanism 4240 of the inner frame 4202 can be fitted into the outer frame mounting mechanism 4220.

[0177] Figure 43 provides a perspective view of at least a portion of an exemplary face covering assembly 4300 according to one or more embodiments. The assembly 4300 is shown without the shaper for illustrative purposes. In some embodiments, the shaper may be removable and / or configured to be attached to an inner frame 4302 via one or more engagement mechanisms 4321 (e.g., hooks, latches, and / or similar mechanisms) configured to engage with the shaper at contact points (see, for example, Figure 41).

[0178] Figure 44 provides a perspective view of at least a portion of an exemplary face covering assembly 4400 according to one or more embodiments. The assembly 4400 is shown without shapers for illustrative purposes. In some embodiments, one or more user engagement mechanisms 4406 (e.g., spectacle-type arms) may be configured to be attached to the outer frame 4403 and / or detachable. For example, the user engagement mechanism 4406 may be detached when a user engagement mechanism of a face mask and / or other filtering element (not shown) is used. In some embodiments, the assembly 4400 may consist of two user engagement mechanisms 4406 (e.g., a right user engagement mechanism 4406a and / or a left user engagement mechanism 4406b), each of which may be configured to contact and / or hook onto a different ear of the user. One or more user engagement mechanisms 4406 may include one or more outer frame engagement mechanisms 4451 (e.g., prongs, hooks, pegs, and / or similar mechanisms) configured to engage with the outer frame 4403 and / or with corresponding mechanisms in the mounting portion 4415 of the outer frame 4403.

[0179] In some embodiments, the user engagement mechanism 4406 may be foldable and / or attached to the outer frame 4403 via hinges and / or similar mountings. The user engagement mechanism 4406 may allow the user to quickly put on and take off the assembly 4400 like sunglasses or reading glasses.

[0180] Figures 45A–45F show an exemplary user engagement mechanism 4506 (e.g., the user engagement mechanism 4506 on the right) of an exemplary face covering assembly (e.g., assembly 4100 in Figure 41), according to one or more embodiments. Figures 45A and 45B provide side views of the user engagement mechanism 4506. Figure 45C is an overhead view of the user engagement mechanism 4506, and Figure 45D is a bottom view of the user engagement mechanism 4506. Figure 45E is a front view of the user engagement mechanism 4506, and Figure 45F is a rear view of the user engagement mechanism 4506.

[0181] In some embodiments, the user engagement mechanism 4506 may include one or more filtering element engagement mechanisms 4509. For example, the filtering element engagement mechanism 4509 may comprise pegs, hooks, notches, and / or other mechanisms connected to receive the straps of a face mask. The user can pull the straps attached to the face mask and / or other filtering elements and / or loop the straps around the user engagement mechanism 4506. In this way, the filtering element can be tightened and / or the straps of the filtering element can be secured to the user engagement mechanism 4506.

[0182] The user engagement mechanism 4506 may include various outer frame engagement mechanisms 4551 configured for attaching the user engagement mechanism 4506 to the outer frame. In some embodiments, the outer frame engagement mechanism 4551 may comprise one or more pegs, notches, hinges, and / or other mechanisms configured to facilitate a secure and / or removable connection between the user engagement mechanism 4506 and the outer frame. For example, the outer frame engagement mechanism 4551 may be configured to receive screws and / or pins through notches and / or openings in the outer frame engagement mechanism 4551. Screws and / or pins may similarly pass through corresponding notches and / or openings in the outer frame. The outer frame engagement mechanism 4551 may be located at the proximal end 4553 of the user engagement mechanism 4506. The user engagement mechanism 4506 may further include a distal end 4555, which may have a reduced height and / or thickness relative to the proximal end 4553.

[0183] In some embodiments, the user engagement mechanism 4506 may have a generally curved shape to facilitate hooking the user engagement mechanism 4506 around the user's ear. As shown in Figures 45A and 45B, the user engagement mechanism 4506 may be curved along a first axis (for example, curved upward over the user's ear and curved downward behind the user's ear). Furthermore, as shown in Figures 45C-45F, the user engagement mechanism 4506 may be additionally or alternatively curved along a second axis. In some embodiments, the distal end 4555 of the user engagement mechanism 4506 may be curved toward the user's head to approximate the curve of the user's head behind the user's ear, and / or may be configured to press against the user's head.

[0184] Figures 46A–46G show an exemplary shaper 4613 of an exemplary face covering assembly (e.g., assembly 4100 in Figure 41) according to one or more embodiments. Figure 46A is a perspective view of the shaper 4613, Figures 46B and 46C are side views of the shaper 4613, Figure 46D is a front view of the shaper 4613, Figure 46E provides a rear view of the shaper 4613, Figure 46F provides an overhead view of the shaper 4613, and Figure 46G provides a bottom view of the shaper 4613.

[0185] The shaper 4613 may include one or more inner frame engagement mechanisms 4616 adapted to mate with corresponding mechanisms of the inner frame (e.g., engagement mechanism 4321 of the inner frame 4302 in Figure 43). For example, the inner frame engagement mechanism 4616 may comprise openings, notches, grooves, divots, pegs, and / or other mechanisms configured to mate with and / or receive corresponding mechanisms of the inner frame. In some embodiments, one or more inner frame engagement mechanisms 4616 may be located on a first attachment 4618a and / or a second attachment 4618b of the shaper 4613. The first attachment 4618a and / or the second attachment 4618b may extend substantially perpendicularly from the central portion 4619 of the shaper 4613 and / or toward the inner frame of the assembly. In some embodiments, the shaper 4613 may include a plurality of inner frame engagement mechanisms 4616. For example, the shaper 4613 may include a series of inner frame engagement mechanisms 4616 aligned along at least a portion of the first attachment 4618a and / or the second attachment 4618b.

[0186] In some embodiments, the inner frame may consist of a plurality of engagement mechanisms adapted to simultaneously engage with the inner frame engagement mechanism 4616 in the first attachment 4618a and the inner frame engagement mechanism 4616 in the second attachment 4618b. The inner frame may be configured to engage with any of the inner frame engagement mechanisms 4616 of the shaper 4613. In some embodiments, the position of the intermediate portion 4619 of the shaper 4613 relative to the inner frame may be adjusted based on which of the inner frame engagement mechanisms 4616 the inner frame engages with. For example, if the inner frame engages with the proximal inner frame engagement mechanism 4616a, the intermediate portion 4619 of the shaper 4613 may be located relatively close to the inner frame. Similarly, if the inner frame engages with the distal inner frame engagement mechanism 4616b, the intermediate portion 4619 of the shaper 4613 may be located relatively far from the inner frame. The shaper 4613 may include one or more inner frame engagement mechanisms 4616 (e.g., two) between the proximal inner frame engagement mechanism 4616a and the distal inner frame engagement mechanism 4616b. The position of the central portion 4619 can determine the position of the filtering element of the assembly (e.g., face mask). Thus, the position of the filtering element relative to the user's face can be adjusted based on which inner frame engagement mechanism 4616 the inner frame engages with. In this way, the user can favorably adjust the shaper 4613.

[0187] Figure 47 provides a perspective view of at least a portion of an exemplary inner frame 4702 coupled to an exemplary cushion element 4705 according to one or more embodiments. In some embodiments, the inner frame 4702 may include a first sealing portion 4712 and / or a shaper (not shown). The first sealing portion 4712 may be configured to form a complete ellipse (e.g., a circle) and / or loop around at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth). In some embodiments, the first sealing portion 4712 may be configured to completely surround at least the user's mouth and / or nose. The first sealing portion 4712 may be configured to facilitate and / or form a complete seal and / or airtight seal around at least a portion of the user's face.

[0188] The first sealing portion 4712 may have any suitable width and / or may be configured to extend so as to be generally away from the user's face when the inner frame 4702 is placed on the user's face. For example, the first sealing portion 4712 may consist of an inner edge 4715 and / or an outer edge 4716, and / or the width may represent the distance between the inner edge 4715 and the outer edge 4716. The inner edge 4715 may be configured to be closer to the user's face than the outer edge 4716 when the inner frame 4702 is placed on the user's face.

[0189] The inner frame 4702 and / or the first sealing portion 4712 may include one or more mounting mechanisms, which may include one or more outer frame mounting mechanisms 4720, a shaper mounting mechanism (e.g., located along the inner diameter of the inner frame 4702; see, for example, Figure 49A), and / or one or more user engagement mounting mechanisms 4721. The outer frame mounting mechanism 4720 may be configured to mate with a corresponding inner frame mounting mechanism on the outer frame. For example, the outer frame mounting mechanism 4720 may include notches, pegs, hooks, and / or similar mechanisms configured to mate with an inner frame mounting mechanism. The user engagement mounting mechanism 4721 may be configured to mate with a corresponding user engagement mechanism, which may include various straps, arms, and / or other mechanisms configured to form attachments to the user's ears and / or other parts of the user's head.

[0190] In some embodiments, the inner frame 4702 and / or the first seal portion 4712 may constitute an eyewear mount (not shown; see, for example, Figure 41) which may be located above or near the first seal portion 4712. For example, the eyewear mount may be configured to be located at or near the highest point of the inner frame 4702 when the inner frame 4702 is placed on the user's face. The eyewear mount may be configured to mate with various eyewear and / or eyewear mounting mechanisms. For example, the eyewear mount may include one or more pegs, clips, notches, and / or other mechanisms configured to receive eyewear and / or eyewear clips and / or to form attachments with eyewear and / or eyewear clips.

[0191] In some embodiments, the inner frame 4702 may be attached to the cushion element 4705 and / or may be configured to be attached to the cushion element 4705. The cushion element 4705 may be configured to contact at least a portion of the user's face when used by the user. The cushion element 4705 may be configured to form a complete ellipse (e.g., a circle) and / or loop around at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth) and / or to approximate and / or match the shape and / or size of the first sealing portion 4712 of the inner frame 4702. In some embodiments, the cushion element 4705 may be configured to completely surround at least the user's mouth and / or nose. The cushion element 4705 may be configured to facilitate and / or create a complete and / or airtight seal around at least a portion of the user's face. In some embodiments, the cushion element 4705 may be configured to bond to and / or otherwise contact the inner frame 4702.

[0192] In some embodiments, the cushion element 4705 may consist of a plurality (e.g., 10) cushion pillows and / or portions separated by ribs and / or partitions. The plurality of cushion portions may be configured to conform independently to the user's face in order to improve sealing around at least a portion of the user's face. The cushion element 4705 may be at least partially constructed of a generally flexible and / or elastic material to allow the cushion element 4705 to conform to the shape of the user's face while forming an airtight seal between the cushion element 4705 and the user's face. The cushion element 4705 may be configured to be permanently or removablely attached to the inner frame 4702 (e.g., using hook-and-loop fasteners and / or other mounting mechanisms and / or materials).

[0193] Figure 48 provides a perspective view of at least a portion of an exemplary inner frame 4802 according to one or more embodiments. The inner frame 4802 is shown without cushioning elements for illustrative purposes. In some embodiments, the inner frame 4802 may include a first sealing portion 4812 and / or a shaper (not shown). The first sealing portion 4812 may be configured to form a complete ellipse (e.g., a circle) and / or loop around at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth).

The first sealing portion 4812 may be configured to facilitate and / or form a complete seal and / or airtight seal around at least a portion of the user's face.

[0194] Figures 49A–49F show an exemplary inner frame 4902 coupled to a cushioning element 4905 of an exemplary face covering assembly (e.g., assembly 4100 in Figure 41) according to one or more embodiments. Figure 49A provides a front view of the inner frame 4902 and / or cushioning element 4905; Figure 49B provides a rear view of the inner frame 4902 and / or cushioning element 4905; Figures 49C and 49D provide side views of the inner frame 4902 and / or cushioning element 4905; Figure 49E provides a bottom view of the inner frame 4902 and / or cushioning element 4905; and Figure 49F provides an overhead view of the inner frame 4902 and / or cushioning element 4905.

[0195] In some embodiments, the inner frame 4902 may include a first sealing portion 4912 and / or a shaper (not shown). The first sealing portion 4912 may be configured to form a complete ellipse (e.g., a circle) and / or loop around at least a portion of the user's face (e.g., around at least a portion of the user's nose and / or mouth). In some embodiments, the first sealing portion 4912 may be configured to completely surround at least the user's mouth and / or nose. The first sealing portion 4912 may be configured to facilitate and / or create a complete seal and / or airtight seal around at least a portion of the user's face.

[0196] The inner frame 4902 and / or the first sealing portion 4912 may include one or more mounting mechanisms, which may include one or more outer frame mounting mechanisms 4920, a shaper mounting mechanism 4922 (e.g., located along the inner diameter of the inner frame 4902), one or more user engagement mounting mechanisms 4921, and / or one or more secondary clip mounting mechanisms 4923 (e.g., one secondary clip mounting mechanism 4923 on each side of the inner frame 4902). One or more user engagement mechanisms 4921 may consist of a generally rectangular projection extending from the outer surface of the first sealing portion 4912 and / or forming a generally elliptical and / or circular lumen. One or more shaper mounting mechanisms 4922 may comprise projections, pegs, notches, and / or arms extending from the first sealing portion 4912 in or near the inner diameter of the inner frame 4902 and / or on the forward-facing side of the inner frame 4902 (e.g., away from the user's face). The shaper mounting mechanism 4922 may include hooks and / or lips connected to pass through and / or hook onto the opening of the shaper and / or the mounting mechanism. The secondary clip mounting mechanism 4923 may consist of a generally elliptical and / or rectangular projection extending laterally from the inner frame 4902 and / or may form an elliptical and / or rectangular lumen configured to receive one or more clips. The lumen of the secondary clip mounting mechanism 4923 may be larger than the lumen of the user engagement mounting mechanism 49.

[0197] Figures 50A–50F show an exemplary outer frame 5003 of an exemplary face covering assembly (e.g., assembly 4100 in Figure 41) according to one or more embodiments. Figure 50A is a perspective view of the outer frame 5003, Figures 50B and 50C are side views of the outer frame 5003, Figure 50D is a front view of the outer frame 5003, and Figure 50E is a rear view of the outer frame 5003, Figure 50F is a bottom view of the outer frame 5003, and Figure 50G is an overhead view of the outer frame 5003. In some embodiments, the outer frame 5003 may include one or more secondary clip attachment mechanisms 5024 (e.g., one secondary clip attachment mechanism 5024 on each side of the outer frame 5003). The secondary clip attachment mechanism 5024 may consist of a generally elliptical clip and / or projection extending generally perpendicularly from the sealing portion of the outer frame 5003, and / or may form a generally elliptical lumen configured to receive one or more ties (e.g., zip ties). One or more secondary clip attachment mechanisms 5024 may extend laterally outward from the sealing portion of the outer frame 5003, and / or may be configured to be positioned on both sides of the user's face when in use.

[0198] Figures 51A and 5IB show exemplary face covering assemblies according to one or more embodiments. In some embodiments, one or more ties 5125 (e.g., zipper ties, latches, cords, strings, hoops, hook-and-loop fastener straps, screw bolts, elastic straps, and / or similar devices) may be used to fasten the inner frame 5102 of the assembly to the outer frame 5103 of the assembly. For example, the inner frame 5102 may include one or more secondary clip attachment mechanisms 5123 having a lumen connected to align with the corresponding lumen of the outer frame secondary clip attachment mechanism 5124 of the outer frame 5103. The ties 5125 may be configured to extend through the inner frame attachment mechanism 5123 and the outer frame attachment mechanism 5124, and / or to securely attach the outer frame attachment mechanism 5124. For example, if a relatively thick filtering element is placed between the inner frame 5102 and the outer frame 5103, some attachment mechanisms of the inner frame 5102 and / or the outer frame 5103 may be prevented from being attached. In such cases, the tie 5125 can provide a secondary fastening option for securing the inner frame 5102 to the outer frame 5103.

[0199] The strings 5125 and / or mounting mechanisms 5123, 5124 may be configured to connect any filter mask to the inner frame 5102 and / or outer frame 5103. The cable ties 5125 and / or mounting mechanisms 5123, 5124 can be used to enhance the customization of the assembly (e.g., snap-fit, tightening, and / or optimization) to the user's preference.

[0200] The seal tie 5125 features additional mechanisms for greater fastening and tightening with various options. These include spools for wrapping ear loops, straps, hook-and-loop fasteners, zip ties, or other similar types of components. Holes in the inner frame 5102 and outer frame 5103 can be used to tighten and secure them together to enhance the seal between the mask and the base / seal.

[0201] The mounting mechanisms 5123 and 5124 on both sides of the frame not only secure the clip to the base, but also allow for customization of the tension needed to optimally fit the shape of the wearer's head and ears.

[0202] Figures 52A–52C illustrate the mounting process of the PPE assembly 5200 according to one or more embodiments. In some embodiments, the assembly 5200 may include a shaper 5213 configured to be mounted to a shaper engagement mechanism 5222 on the inner frame 5202 of the assembly 5200. The shaper 5213 may include a plurality of inner frame engagement mechanisms 5216, including a proximal engagement mechanism 5216a and / or a distal engagement mechanism 5216b. The shaper 5213 may be moved toward the inner frame 5202 to cause mounting of one or more inner frame engagement mechanisms 5216 to the shaper engagement mechanism 5222.

[0205] The assemblies described herein can provide and / or be configured to offer many unique mechanisms for protecting the wearer from airborne pollutants. The melt-blown material of many masks provides optimal filtration of pollutants if all air passes through the material. Many masks today have gaps and leaks, which can cause pollutants to enter the lungs without passing through the filter material.

[0206] The assembly described herein features a rigid base and a specially integrated fitting seal, providing a superior and comfortable seal around the face. The filter element (such as a mask) that fits over the base has an additional external clip, which has two areas that snap into place to secure it to the base, providing a good seal between the mask and the seal / base.

[0207] The secondary attachment mechanism provides additional mechanisms for greater fixation and tightening with various options, such as ear loops, straps, hook-and-loop fasteners, zip ties, and spools for wrapping other similar types of components. Holes in the base and clip can be used to tighten and secure the two together to improve the sealing between the mask and the base / seal.

[0208] The spool mechanism on both sides of the clip and arm frame allows you to customize the tension to best fit the wearer's head and ear shape. The base has holes at the top and bottom, allowing you to connect the upper and lower head straps to secure the PPE kit to the face, wrapping around the back of the head.

[0209] Examples of face coverings include over 1900 designs and 20 functions, achieving improved comfort, airtightness, breathability, shape and structure, extended wear period, reduced environmental impact, and cost savings. Surgical PPE masks are remolded to maintain material structure and effectiveness comparable to N95 masks.

[0210] Polypropylene masks made of woven or meltblown nonwoven fabric without added conversion or sealing kits may leak or gap, especially when worn by the general public who have not received training in mask fitting. Furthermore, many masks, such as N95 masks and surgical masks, are not designed for all-day use by the general public. In contrast to many surgical masks, which cover the face and have little material in contact with the nose and mouth for actual filtration, it may be important and / or significant to have an airtight seal with a proper fit that conforms to all / partial features of the face, and to increase the amount of filter material away from the face, allowing more material to be used for filtration and breathability. If a mask is not worn properly or is worn continuously throughout the day, gaps and leaks can occur, which, according to one study, may reduce the effectiveness of such a mask by more than 50%. Mask conversion kits according to aspects of this disclosure can use a regular mask and improve its function and fit.

[0211] Furthermore, the supply of high-end N95 masks is generally limited, and such masks may require two or more additional mechanical manufacturing processes to create a rigid mask shape in order to produce a higher level of sealing and fit. Surgical masks, on the other hand, are generally relatively flat and loose, with relatively low stability, widespread leakage and gaps, and due to their loose, paper-like material, may not adequately protect against the general public's viruses and bacteria, with little space for filtration and breathability, and tend to overlap over the mouth and nose. Currently, most surgical mask materials may be used to spread around the face to create a seal rather than lifting forward, in order to produce more filtration and easier breathability.

[0212] As described above, standard N95 masks and surgical masks can consist of electrostatically melt-blown polypropylene that forms a nanoweb-type filtration. Embodiments of this disclosure can transform a loosely flat surgical mask into a mask assembly that has a relatively high level of facial fit, greater separation from the mouth and nose, improved / sealing, improved comfort, and a larger surface area of ​​filtration away from the face, compared to a surgical mask that does not undergo such a transformation. Thus, a relatively inexpensive (e.g., about $0.20) surgical mask can be transformed into a mask assembly that has the advantages of a relatively expensive (e.g., about $5.00) N95 mask, thereby providing superior mask protection to the general public in a relatively affordable assembly.
