Embodiment Construction

[0033] The present invention will now be described with reference to the accompanying drawings. For the sake of clarity, the numbering of parts in the figures is not repeated for the same parts in subsequent figures, but should be apparent from the figures.

[0034] see Figure 1A and Figure 1B , shows an embodiment of the mask of the present invention. The mask 10 has a mask body 12 and a front grille element 14 . The mask body has a soft flexible face seal 15. The front grille element has a support element 18a, a connector 20 for headgear (ie a strap or the like) and at least one air outlet grille 16a. A replaceable filter element 22 is positioned (ie, sandwiched) between the mask body and the front grille element. There are holes or notches 24a in the front grill element for receiving nubs on the mask body when the mask is assembled.

[0035] As can be seen from the figure, the profile of the mask body of the mask of the present invention corresponds to the user's fac...

Abstract

The present invention is a particulate filter face mask with replaceable filter element, the filter element being inexpensive, easily replaceable and securely held within the mask when installed.

Description

Background technique [0001] Wearing a face mask filters particles and unwanted gases from the air, allowing the wearer to breathe the air freely. Prior art face masks that filter particles are often ineffective and / or uncomfortable for the wearer. Ineffective existing masks typically seal poorly and allow air to pass, eg, between the edge of the mask and the wearer's face or around the filter, whereby air can bypass the filter and expose the wearer to pollutants. Ineffective face shields provide limited protection to the wearer and can add negative health effects. [0002] Uncomfortable masks can lead to low user compliance and can also lead to an increase in health problems. Uncomfortable masks may press into one or more areas of the wearer's face, be inherently too heavy to wear for extended periods of time or cause condensation to form beneath the mask such that the wearer needs to move the mask to evaporate condensation, but this would allow Unfiltered air enters under ...
