Filtrete 20-in x 25-in x 4-in 1000 MPR Allergen Defense 2-Pack Electrostatic Pleated Air Filter

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). 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.
