Filtrete - 16 in. W X 25 in. H X 4-5/16 in. D Polyester 1550 MPR Pleated Allergen Air Filter 1 pk

Deep‑pleat filters like this are built to turn a whole‑house media cabinet into a high‑efficiency air cleaner with long service life. With a 1550 MPR (MERV 12) rating and electrostatically charged polyester media, the 16x25x4‑5/16 allergen filter is engineered to pull in and trap countless microparticles such as pet dander, smoke, smog, bacteria, and roughly half of small virus‑carrying particles.
