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 5 out of 5 by from Choice of MERV ratings and size Nominal size of HVAC filters is a problem for some users. The problem is made worse by the lack of standardization in return air grille sizes. For example, filter manufacturers print 18"X18" on a filter, but the nominal size can make it impossible to use them in a return air grille, if the builder bought cheap odd-size grilles. For the past two decades, I have had no problem with the Filtrete size in my house. Not true for other filters I tried. I have a large return air grille that I have to tape two 18X18 together to use. 18X36 is not a common size to find and I do not think Filtrete makes this size (with 18X24 the largest I could find). Once I bought another big-name brand. After taping the two together, the length of the filter was too short. [This review was collected as part of a promotion.]

Rated 1 out of 5 by from doesn't fit I have no idea what to do with this BETTER AND HIGHER END filter... this is the first time a 16 x 20 x 1 inch filter purchased at the local hardware store DOESN'T FIT. I have an AC unit with a more precise slot in which to insert the filter. No matter how I try, it just won't slide down the frame as required. I can't return the unit for a lower grade filter because I didn't save the receipt.

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.]
