The Flanders Replacement Air Cleaner is designed as a MERV 11 rated air filter. These 20" x 20" x 4.5" pleated filters are constructed from a polypropylene and a polyethylene electrostatic media to capture airborne contaminants. These cartridges are designed for use with Honeywell air cleaner housings.
Electrostatic Charge - A natural electrostatic charge catches and holds airborne contaminants especially dust.
Pleated Shape - With a pleated shape, filters resist collapsing, warping, or bending in normal service.
High Dust Holding Capacity - A high dust holding capacity extends the service life of your filter by allowing it to retain high quantities of dust before replacement.
