Filtrete - 20 in. W X 20 in. H X 1 in. D Polypropylene 700 MPR Pleated Air Filter 1 pk

Optimized for routine home HVAC filtration, this pleated polypropylene air filter helps trap everyday airborne particles—such as dust, lint, pollen, pet dander, and dust mite debris—as they pass through your heating and cooling system, and is typically replaced about every 90 days for consistent performance. Its electrostatically charged 700 MPR (MERV 8) media boosts particle capture compared with basic non‑pleated filters.
