    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 432.
    Rated 4 out of 5 by from Keeps household air cleaner Easy to install, takes most dust particles out of the air

    Rated 5 out of 5 by from Helps keep the grime at bay... Living in the Central Valley translates into gross and dirty air 355 days a year. Between what is pushed in from all four surrounding areas of the state as well as all of our own pollution and allergens from the crops and farms, we need good quality air filters. I have been extremely impressed with the amount of crud these filters can filter and trap. I change mine every month and a half or so, especially during fire season. They go in white and come out brownish-black. It is horrifying to think about breathing that in and what our lungs would look like. So, thanks filtrate for keeping the nasty at bay.

    Rated 4 out of 5 by from 1000 filter Filtrete I buy these filters and replace them every two months. Seems to work well.

    Rated 5 out of 5 by from Saves on Dusting I first bought this filter because it was on sale. I have been doing a lot of remodeling (new floors, drywall, windows, doors, etc) and I was sure all of my rooms were going to be a dusty mess. But I keep the doors closed and the filter keeps the dust from being spread throughout the house through the heating vents. This filter saves me a lot of cleaning time so I won't go back to anything else!

    Rated 5 out of 5 by from Great product! I’ve been using these for several years now, and I am VERY PLEASED with how much they filter. I try to change them every 1-3 months, depending on how much they are filtering.

    Rated 5 out of 5 by from Keeps my allergies at bay We have a furnace that uses the 16x25x4 size allergen filter, and we keep either the heat or the air on all year because of my allergies--no open windows, doctor's orders. I've noticed that there is very little dust on my furniture since using the Allergen Defense filter, which lasts for a year, and I have little or no allergy symptoms indoors. It helps me breathe easier!

    Rated 5 out of 5 by from Love it!!! I am a habitual buyer of this filter it keeps our furnace going. Generous rebate offers. Wish more stores carry this brand in stock.

    Rated 5 out of 5 by from Long Lasting! The cheapie filters do not last a month before they need to be changed. Filtretes go at least 3 months, and longer in the summer months for us. My wife notices cleaner air and less dust in our home. The additional value speaks for itself. If you want to "save $", stop buying bottled water!
