Filtrete - 20 in. W X 24 in. H X 1 in. D 300 MPR Pleated Filter Dust 1 pk - Case of 4

Every heating or cooling cycle pushes household air back through this pleated panel, where it helps knock down basic dust loading before air recirculates. With a 300 MPR (MERV 5) rating and Filtrete 3‑in‑1 electrostatic media, the 20x24x1 Basic Dust filter is designed to attract and capture larger particles such as household dust, lint, and dust‑mite debris while allowing good air flow.
