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.
