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.

This electrostatically charged polypropylene pleated filter works continuously to trap common household contaminants such as dust, pollen, pet dander, and lint as they pass through your furnace or central air conditioning system. With a 700 MPR performance rating (approximately MERV 8), it provides enhanced filtration over basic non‑pleated filters while maintaining dependable airflow in 1‑inch filter slots, and should be replaced roughly every 90 days for best results.
