The Filtrete Allergen Defense Filter outperforms non-electrostatic pleated and washable 1-inch filters at capturing microscopic allergens like dust, smoke, and smog particles and large allergens like mold spores and pet dander.

  • #1 Recommended Brand* (*Filtrete Brand is the most recommended brand of HVAC Air Filters based on the US Filtrete Brand Health Tracker, Ipsos, June 2022)
  • 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
  • FOR OPTIMAL PERFORMANCE of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1 in. filters
  • 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!
  • OUTPERFORMS FIBERGLASS, WASHABLE AND NON-ELECTROSTATIC 3-month pleated 1 in. home air filters for your furnace, air conditioner or HVAC system
