ABSTRACT:
Embodiments of the invention generally provide a frame assembly having an integral holding frame/clamp. The frame assembly is typically mounted in a housing of an air handler or other air moving conduit. The holding frame/clamp is coupled to the frame assembly by a hinge. The holding frame/lamp is configured to retain a prefilter. When the holding frame/clamp is to a closed position, the holding frame/clamp urges a final filter sealingly against the frame assembly. The clamp holding frame/clamp is maintained in the closed position by a latch. The latch facilitates removal and replacement of the final ter rapidly without tools, thereby substantially reducing the expense associated with filter change out.
