Filtrete 20x25x1 AC Furnace Air Filter, MERV 11, 3-Month Pleated Electrostatic Air Cleaning Filter, 6-Pack

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). The Filtrete Allergen Defense Air Filter is designed with exclusive Filtrete Brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner air flow through. It attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog, with a rating of MERV 11 and an MPR of 1000.

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. Filtrete offers a range of sizes, including MPR 1000, MPR 1200 and MPR 1550, available in 4 in., 4 in. slim fit and 5 in. thick air filters. For optimal performance of your heating & cooling system or HVAC system, it is recommended to 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. To help you stay on top of filter changes, Filtrete offers a filter change reminder program that works for you. Simply use the Filtrete Smart 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.

The Filtrete Allergen Defense Air Filter outperforms fiberglass, washable and non-electrostatic 3-month pleated 1 in. home air filters for your furnace, air conditioner or HVAC system. It is designed for residential use only and can help create a cleaner, healthier indoor environment for your home.
