Vent Filter

Abstract

This article is made of nonwoven fabric partially coated with a transparent adhesive, and can be attached to the louvers of outdoor ventilation vents or indoor ventilation vents to prevent them from getting dirty. The adhesive-coated side is attached to the louvers or vents. As a result, dirt adheres to the breathable nonwoven fabric, but dirt does not easily adhere to the nonwoven fabric part coated with the adhesive, so that the coating appears white as shown in the "Reference back view showing the state after use," indicating when it is time to replace the product. This article is cut out appropriately to fit the size and shape of the louvers or vents. Note that, as shown in the "Reference front view showing the cut-out state," ears can be formed by cutting along the outer periphery of the adhesive included in the part for which design registration is sought. For example, when the present product is attached to the louver of an outdoor vent by forming ears as shown in Reference Figures 1 and 2, which show the usage state, by attaching the ears on which the adhesive is formed to the side of the louver, the filter is attached not only to the front but also to the side of the louver as shown in Reference Figure 2, which further prevents the filter from falling off the louver compared to when the filter is attached only to the front side of the louver. The same applies when attaching to an indoor vent.
