Filtrete 20x25x1, AC Furnace Air Filter, MPR 1000, Micro Allergen Defense, 6-Pack
- 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.
- For optimal performance, change your home air filter at least every 90 days for 1 inch filters, and at least every 12 months for 4 inch and 5 inch filters.
- 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.
