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).

  • 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!

Rated 4 out of 5 by from better air flow Installed this filter two weeks ago and have seen a definite improvement over the better rated ones, seems like my a/c has shorter run cycles and my house is as cool as before. I will use this level of filter from now on. Also the last two weeks we have had record setting temperatures almost each day. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Trust my Filtreate Filter I have used nothing but Filtrete Allergen Filters for the past 15 years. I trust them to keep us healthy and allergy free in the home. My wife has asthma so its imperative we have the best air filter we can get. That is why I buy Filtrete. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Good quality I bought this because I wasn't satisfied with the flimsy green filters we were getting. This filter seems to "grab" a lot more than what the cheap ones did. I just found out that my toddler son has many environmental allergies so I will be getting the higher grade Filtrete filter when this one is ready for replacement.

Rated 5 out of 5 by from Good filters - people need to stop second guessing I've always wanted a decent filter that allowed for superior air flow after pleated filters pushed the old fiberglass filters out of the market. These excellent, inexpensive, free-flowing filters are perfect. Several reviews here are complaining about the airflow arrow being backwards. Just follow the installation instructions, don't second guess the engineers, and you'll be fine. I've been using these for years in my own home (two air handlers, four filters) and two rental units (one air handler each). Never had a problem. They work well, they're light but durable. And they definitely improve heating/cooling efficiency over the restrictive filters most people use now. Worth noting that studies done on HVAC air filtration show that no matter what kind of filter you use, you don't get most of the dust in your house anyway because it's resting on surfaces and embedded in carpets and pillows. So no matter how high a MERV rating you use, you end up breathing all the dust as you move around the house stirring it up before it ever gets near your filter.

Rated 4 out of 5 by from Traps dust!! We live on a dirt road and apparently we get more dust coming in our house than you would think! This filter works great, however because where we live it lasts about two months instead of three! Well worth the clean air tho!! [This review was collected as part of a promotion.]
