3M Filtrete 14 x 20 x 1-Inch 1000 MPR MERV 11 Allergen Defense Furnace Air Filter - 49100M

The Filtrete™ allergen defense filter outperforms non-electrostatic pleated and washable 1 In. filters at capturing microscopic allergens like dust, smoke, and smog particles and large allergens like mold spores and pet dander. Filtrete 14x20x1 MPR 1000 air filter, made by 3M, helps capture unwanted particles from your household air to contribute to a cleaner, fresher home environment. Designed with exclusive Filtrete 3-in-1 technology, including a MPR 1000 and MERV 11 rating, your AC filter will help pull and capture countless microparticles - such as pet dander, smoke and smog - while letting cleaner air flow through. Your Filtrete filter will also capture large particles, including lint, pollen and household dust. Use a 3-month pleated 1 In. home HVAC filter in your furnace, air conditioner or HVAC system. For optimal performance of your heating and cooling system or HVAC system, change your furnace filter at least every 90 days. Residential use only.
