20x25x1 Air Filter, MERV 11, Micro Allergen Defense, 6 Pack

Upgrade your central heating and cooling system with a Filtrete Allergen Defense Air Filter for comprehensive whole-home air filtration. This powerful filter efficiently captures particles of all sizes, from large ones like lint, pollen, dust, and pet dander, to microscopic ones like smoke and smog. It outperforms fiberglass, washable, and non-electrostatic 3-month pleated 1 in. home air filters for your furnace, air conditioner, or HVAC system.

Designed with exclusive Filtrete Brand 3-in-1 technology from 3M, this filter traps unwanted air particles while allowing cleaner air to flow through. It attracts and captures particles such as lint, pollen, dust, pet dander, smoke, and smog. It has a 1000 MPR rating of MERV 11, and the higher the MPR, the more microparticles it will capture from the air passing through it, including pollen, pet dander, smoke, bacteria, and viruses.

Various sizes are available, including MPR 1000, MPR 1200, and MPR 1550 in 4 in., 4 in. slim fit, and 5 in. thick air filters. For optimal performance of your heating & cooling or HVAC system, change your home air filter at least every 90 days for 1 in. filters, and at least every 12 months for 4 in. and 5 in. filters. A dirty filter can slow down air flow and make the system work harder, wasting energy. Consider signing up for a filter change reminder program for added convenience.

Please note that this product is for residential use only. You can create a change countdown in the Filtrete Smart app by scanning the barcode on your filter's packaging and choosing a replacement countdown of 30, 60, or 90 days. When the filter's lifespan is up, you'll receive a notification to change it.
