    Opt for a Filtrete™ Allergen Defense 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).

    • 1000 MPR has a rating of MERV 11
    • 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
    • FIND YOUR SIZE: 1000 MPR available in 4in. , 4in. slim fit and 5in. thick 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 in. filters, and at least every 12 months for 4 in. and 5 in. filters
    • 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 (www.filtrete.com/ChangeReminders) that works for you!
    • FOR RESIDENTIAL use only
    • CREATE A CHANGE COUNTDOWN in the Filtrete™ Smart app. Simply use the app to scan the barcode on your filter’s packaging, then choose 30, 60 or 90 days for your replacement countdown. When the lifespan is up, you’ll get a notification to change your filter

    Filtrete™ MPR 1000 Allergen Defense Air Filters (4" - 6") is rated 4.8 out of 5 by 464.
    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 SUPERB Filter! What a difference since I started using the FILTRETE brand Filters! I will never go back to the inferior filters that I used to use. The FILTRETE brand is far superior to others that are sold, and all of my friends and family agree that tried them agree !

    Rated 5 out of 5 by from Keep Several In Stock I always keep several air filters so I can changed them every three months or as needed. Filtrete is my favorite so I keep an eye out to purchase them on sale so I have a ready supply. It keeps the air cleaner and helps protect my furnace.
