Filtrete MERV 11 Micro Allergen Defense Air 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). Designed with exclusive Filtrete Brand 3-in-1 technology from 3M, the filter traps unwanted air particles while letting cleaner air flow through, attracting and capturing particles such as lint, pollen, dust, pet dander, smoke and smog.

The 1000 MPR filter has a rating of MERV 11, and 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 Allergen Defense Air Filters are available in 4 in., 4 in. slim fit and 5 in. thick sizes, with MPR ratings of 1000, 1200 and 1550.

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 that works for you!

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.

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.
