From The Manufacturer
Outperforms fiberglass, washable and non-electrostatic 3-month pleated 1″ home air filters for your furnace, air conditioner, or HVAC system. Exclusive Filtrete Brand 3-in-1 technology from 3M traps unwanted air particles, letting cleaner air flow through. Filtrete 1000 MPR (Microparticle Performance Rating) equates to MERV 11. 1000 and 1200 MPR also available in 4”, 4” slim fit and 5” air filters.Material: Synthetic. For optimal performance, change your home air filter at least every 90 days for 1” filters, and at least every 12 months for 4” and 5” filters. For residential use only. 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. 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!
