About This Item
Homes using slim 4‑inch media cabinets can step up from basic filtration with this deep‑pleat 20x25x4 Slim Fit filter, which uses Filtrete’s 1550 MPR (MERV 12) electrostatic polyester/synthetic media to capture a high percentage of fine airborne particles. Designed with 3‑in‑1 technology, it helps pull in and trap numerous microparticles—such as pet dander, smoke, bacteria, and a significant share of virus‑carrying aerosols.
