Higher MPR means better filtration of microparticles like pollen, pet dander, smoke, bacteria, and viruses. For optimal performance of your heating and cooling system, change your home air filter at least every 90 days for 1-inch filters. A dirty filter can slow down air flow and make the system work harder, wasting energy. Sign-up for a filter change reminder program that works for you!
Our filter outperforms fiberglass and washable, non-electrostatic filters. It is designed with exclusive 3M Filtrete 3-in-1 technology to trap unwanted particles while letting cleaner air through.
This filter attracts and captures microscopic particles like smoke, cough and sneeze debris, bacteria, and viruses. It also traps larger particles such as lint, household dust, and pollen. Our filter captures 62% of small particles (like bacteria and virus-carrying particles) as tested by ASHRAE 52.2 for 0.3 to 1 micron particles.
