19-75x21-5x1 MERV 11 Air Filter

MERV 11 synthetic media (comparable with MPR 1000 - 1200 & FPR 7) protects homes from pets, allergies, and more by trapping 95% of airborne particles without impacting air flow. Electrostatically charged, pleated filters capture more harmful particles, last 3x longer than fiberglass models, and are 100% manufactured within the United States. Industrial grade beverage board (recyclable) frames with dual wire backings improve structural integrity and outperform standard cardboard designs. If you receive items with a different label, frame, or media than what is pictured, please note that any such alteration is purely cosmetic and your filter will still function exactly as described
