Filtrete MPR 1000 Micro Allergen Defense Air Filter, 20x25x4, 2-Pack

Enhance your central heating and cooling system’s air filtration with a Filtrete Allergen Defense Air Filter. This straightforward filter is effective in capturing particles of varying 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.

The filter is designed with exclusive Filtrete Brand 3-in-1 technology from 3M, designed to trap unwanted air particles while allowing cleaner air flow through. It has a 1000 MPR rating of MERV 11, capturing microparticles such as pollen, pet dander, smoke, bacteria, and viruses. The higher the MPR, the more microparticles your filter will capture from the air passing through it.

You can find your size in MPR 1000, MPR 1200, and MPR 1550 available in 4 in., 4 in. slim fit, and 5 in. thick air filters. For optimal performance of your heating & cooling system 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 will impede air flow and cause the system to work harder, wasting energy. You can sign up for a filter change reminder program.

The Filtrete Smart app allows you to create a change countdown. Simply scan the barcode on your filter’s packaging using the app, then choose 30, 60, or 90 days for your replacement countdown. When the filter’s lifespan is up, you’ll receive a notification to change your filter. Please note that these filters are for residential use only.
