Filtrete - Ultra 20 in. W X 25 in. H X 5 in. D Polyester 1550 MPR Pleated Allergen Air Filter 1 pk

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.

This disposable deep pleated air filter cartridge is specially designed to work in a Honeywell whole-house air cleaner. The filtering medium is made with synthetic mechanical filtering fibers. The medium is adhered to an expanded metal backing, deep pleated and encased in a moisture resistant Kraft board frame. It offers a MERV 8 level of performance.

Built for whole‑house air cleaners that accept 5‑inch media, this deep‑pleated Flanders cartridge uses synthetic electrostatic material rated MERV 8 to capture common household contaminants while keeping resistance to airflow relatively low. It helps reduce dust, lint, pollen, mold spores, and other everyday particles for up to a year of service in many residential systems.
