- Exclusive Filtrete™ Brand 3-in-1 technology from 3M traps unwanted air particles, letting cleaner air flow through
- Filtrete 800 MPR has a rating of MERV 9
- 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” 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 (www.filtrete.com/changereminders) that works for you!
