    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!

    Filtrete™ Allergen Defense Air Filters is rated 4.7 out of 5 by 442.
    Rated 5 out of 5 by from Amazed!! I purchased this filter and was totally amazed at the performance of this filter! The other brands I purchased flopped in my unit and I would hear it move each time the unit came on/off. This filter fits like a glove, never moves. Overall I am extremely pleased with my purchase, allergies are better as well! Winner!!!

    Rated 5 out of 5 by from Made a huge difference in the smell of the house! I had metallic filters in the air cleaner but there was always a strange smell from them. A furnace technician told me to get A filtret to replace the metal one. The difference was immediate! No more smell! Now I just replace it when needed and am very happy.
