Filtrete™ Allergen Defense Air Filter, 20" x 20" x 1"
- 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” 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!
Opt for a Filtrete™ Allergen Defense Air Filter to transform your central heating and cooling system into a whole-home air filtration operation. This no-nonsense filter helps capture varying sizes of particles, from the large (lint, pollen, dust and pet dander) to the microscopic (smoke and smog).
