The Protector - Custom Size AC Furnace Air Filter

Our 2-Ply Antimicrobial Filter is tougher than those cardboard-framed filters that hold moisture. The Protector is built with a proprietary antimicrobial filter media making it impenetrable to mold and microbial growth. Trust us, pleats are a bad idea on pants and even worse on filters. Tight Fit - Eliminates the risk of unfiltered air passing around your air filter. Mold and Moisture Resistant - No mold or microbials hit your air. (because we trap them!) Depth Loading Arrangement - Traps all particles allowing air to still flow freely through the filter. (even the tiny stuff) Fits All Depths - Will fit in 2,4,5, even 6" depth. (yes, seems funny but it will 100% work) Free Shipping - Don't pay extra for shipping. (because we love YOU and clean air)
