Product Description
Filtrete 20x30x1 MPR 2200 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 high MPR 2200 and MERV 13 rating, your AC filter will help pull and capture countless microparticles – such as pet dander, smoke, bacteria and viruses – while letting cleaner air flow through. This HVAC filter captures up to 69% of small particles (1) and 78% of airborne virus particles (2) to help make your air cleaner. Your Filtrete Filter will also capture large particles, including lint, pollen and household dust. This filter is CERTIFIED asthma and allergy-friendly (3). Use one of the two 3-month pleated 1-inch home air filters in your furnace, air conditioner or HVAC system. Change your furnace filter at least every 90 days.
