Product Details
  • 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
  • Available in 800, 1000, 1085 and 1200 MPR (Microparticle Performance Rating) and have a rating of MERV 11
  • 1000 and 1200 MPR also available in 4”, 4” slim fit and 5” air filters
  • For optimal performance of your heating & cooling system or HVAC system, 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!

Opt for a Filtrete™ Pollen & Pet Dander OR Allergen Defense OR Allergen Defense Extra OR Allergen Reduction 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).

Rated 5 out of 5 by from Helps keep the grime at bay... Living in the Central Valley translates into gross and dirty air 355 days a year. Between what is pushed in from all four surrounding areas of the state as well as all of our own pollution and allergens from the crops and farms, we need good quality air filters. I have been extremely impressed with the amount of crud these filters can filter and trap. I change mine every month and a half or so, especially during fire season. They go in white and come out brownish-black. It is horrifying to think about breathing that in and what our lungs would look like. So, thanks filtrate for keeping the nasty at bay.
