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.
