Filtrete - 20 in. W X 30 in. H X 1 in. D Polypropylene 700 MPR Pleated Air Filter 1 pk

This pleated air filter is engineered to help improve indoor air quality by capturing common airborne particles such as dust, pollen, pet dander, lint, mold spores, and some smoke‑related particles. The electrostatically charged polypropylene media attracts and traps contaminants as air passes through, supporting cleaner airflow in compatible residential HVAC systems.
