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. 1000 MPR & 1085 MPR have 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. FIND YOUR SIZE: 1000 MPR available in 4in. , 4in. slim fit and 5in. 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 slow down air flow and make the system work harder to keep you warm or cool–wasting energy. FOR RESIDENTIAL use only.
