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 1128.
Rated 5 out of 5 by from Great product!! Once I started using them I won't go back to another

Rated 4 out of 5 by from Good Filter My husband came home with this air filter. I changed it out and watched it over the last month. It works good. A little heavy in thickness so not sure how well it filters through but it does the job.

Rated 5 out of 5 by from Works as advertised Very happy with these filters. They are easy to install and work great in my desert Southwest home where we get lots of wind that carries dust and pollen.

Rated 1 out of 5 by from Not true to size I bought two different sizes (12x24x1 and 16x20x1). Both sizes are slightly larger than the size stated and will not fit in the openings. Very poor quality.

Rated 5 out of 5 by from Does the job! Cool air again and product seems to deliver as promised.
Date published: 2020-03-23
Rated 5 out of 5 by from Keeps the dust down and the allergies controlled I have used this type of filter for over 10 years and have never been disappointed in the quality or performance.

Rated 4 out of 5 by from Restricted Air Flow Why is there so much cardboard restricting the airflow? I remove all crisscrossed cardboard from the middle of both sides and they work fine with better airflow. [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Always effective! I've been using Filtrete filters for years. I've always loved how effectively they keep our home's air clean. [This review was collected as part of a promotion.]
