Filtrete 1-in 1085 MPR Allergen Defense Extra 4-Pack Electrostatic Pleated Air Filter

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 to trap unwanted air particles while letting cleaner air flow through. Attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog. 1085 MPR has a rating of MERV 11. The higher the MPR, the more microparticles-such as pollen, pet dander, smoke, bacteria and viruses-your filter will capture from the air passing through it. American Lung Association Health Partner ( The American Lung Association does not endorse any product). For optimal performance of your heating and 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 slow down air flow and make the system work harder to keep you warm or cool-wasting energy. Sign-up for a filter change reminder program that works for you.
