ABSTRACT:
A combined air filter and diffuser for attachment beneath an air discharge duct discharging blown air into a room of a building. The air filter is configured to abut and be flushly mounted to the ceiling immediately below the duct. The filter has a housing including a track disposed to receive a flat air filter element so that the filter element lies horizontally proximate the ceiling. The housing has a slidably removable closure exposing the filter element for removal, which is accomplished by sliding the filter element horizontally from the housing. The housing includes a diffuser having pivotally mounted fins disposed immediately below the filter element. The housing mounts to the ceiling by receiving fasteners through small opening formed in an upper, horizontal wall of the housing.
