Flanders - 20 in. W X 20 in. H X 5 in. D Synthetic 8 MERV Pleated Air Filter 1 pk - Case of 2

Deep-pleated cartridges like this are built for whole-house air cleaners, giving you more media area and longer service life than a standard 1‑inch furnace filter. The 20x20x4.5 synthetic cartridge uses electrostatic polypropylene/polyethylene media with a MERV 8 rating to capture common household contaminants and some bacteria while keeping airflow resistance relatively low. Designed as a replacement for select Honeywell and Air Bear-style air cleaner housings.

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.
