Abstract
A media filter cabinet for a gas furnace is sized to accept a high-efficiency media filter while being easily adaptable to accept a standard size filter. A perforated duct flange on one side of the cabinet permits ease of installation since the flange can be bent at 90 or 180 degrees along the perforations, or removed, depending on the type of duct the cabinet is installed with. The cabinet is adapted to fit a standard filter by using a removable bracket and a wire to retain the standard filter within the cabinet. With the removal of a front door and a back side of the cabinet, the cabinet collapses to diminish its shipping size. In one embodiment, the cabinet is in kit form which is easily assembled.
