About This Item
Deep‑pleat media filters like this are designed to give whole‑house systems higher allergen capture and longer life than standard 1‑inch panels. With a 1550 MPR (MERV 12) rating and electrostatically charged polyester media, the 20x25x4 filter is engineered to pull in and trap countless microparticles such as pet dander, smoke, smog, bacteria, and around half of small virus‑carrying particles, while also capturing larger debris.
