Filtrete - 18 in. W X 25 in. H X 1 in. D Polypropylene 700 MPR Pleated Air Filter 1 pk - Case of 4

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.

Formulated for standard residential heating and cooling systems, this electrostatically charged polypropylene pleated filter works to capture everyday household particles such as dust, lint, pollen, and pet dander as air recirculates through your home, contributing to cleaner indoor air when changed on a typical three‑month schedule. The 700 MPR (MERV 8‑level) media provides better filtration performance than basic fiberglass filters.

Dust, lint, and dust‑mite debris are common in return air, and this pleated panel is aimed at reducing that everyday load without over‑restricting airflow. With a 300 MPR (MERV 5) rating and Filtrete 3‑in‑1 electrostatic media, the 18x24x1 Basic Dust filter is designed to attract and capture larger household particles as air passes through your furnace or AC.
