Filtrete - 18 in. W X 24 in. H X 1 in. D Polypropylene 700 MPR Pleated Air Filter 1 pk

This pleated air filter is designed to help improve indoor air quality by capturing common airborne particles such as dust, pollen, pet dander, lint, and mold spores. The electrostatic polypropylene media enhances particle attraction while maintaining relatively low airflow resistance for compatible HVAC systems. It is intended for regular replacement rather than cleaning and works best when changed every one to three months, depending on household conditions and system usage.
