Vent Filter

Abstract

This product consists of nonwoven fabric partially coated with a transparent adhesive, and is attached to ventilation fans, air conditioners, vents, etc. to prevent dirt from dust and other contaminants. The product is configured so that four usable units are connected lengthwise, with the portion shown in the "enlarged view of part AA" being one unit. To install, cut it to the desired size based on the size of the ventilation fan, air conditioner, vent, etc. to be used, peel off the release sheet, and attach the adhesive-coated side. As a result, while dirt adheres to the breathable nonwoven fabric portion, dirt does not easily adhere to the adhesive-coated portion of the nonwoven fabric. As shown in the "reference back view showing the condition of part AA after use," the adhesive-coated portion appears white, indicating when it is time to replace it.
