Filtrete 14x20x1 AC Furnace Air Filter, MERV 11, MPR 1000, Micro Allergen Defense, 3-Month, 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). Designed with exclusive Filtrete Brand 3-in-1 technology from 3M, it is engineered to trap unwanted air particles while allowing cleaner air to flow through. The higher the MPR (Microparticle Performance Rating), the more microparticles, such as pollen, pet dander, smoke, bacteria and viruses, the filter will capture from the air passing through it.

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. With a rating of MERV 11, the 1000 MPR filter attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog. 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 can slow down air flow and make the system work harder to keep you warm or cool, wasting energy.

To ensure timely filter changes, sign-up for a filter change reminder program that works for you. The Filtrete Smart app allows you to create a change countdown by simply scanning the barcode on your filter's packaging and choosing 30, 60 or 90 days for your replacement countdown. When the lifespan is up, you'll receive a notification to change your filter. This feature helps maintain optimal indoor air quality and the efficient operation of your HVAC system.

The Filtrete Allergen Defense Air Filter is available in various sizes, including MPR 1000, MPR 1200 and MPR 1550, in 4 in., 4 in. slim fit and 5 in. thick air filters, to accommodate different system requirements. This product is designed for residential use only, ensuring a clean and comfortable living environment for your home.
