Duct-Mounted F35 Series

Our F35 series of Honeywell Media Air Cleaners mount out of sight, in the ductwork near your equipment. A gasket on the door helps prevent air leakage.

Return Grille F35 Series

Our F35R series of Honeywell Media Air Filters have the same low initial pressure drop and high efficiency as the duct-mounted models. Although over 4 inches wide they easily replace the standard one-inch filter in a standard filter grille, and come complete with plastic frame, combs and gaskets.
