Abstract
A frame supports a deep filter element to allow the filter element to be installed in a duct's conventional air intake opening as a replacement for a conventional shallow filter element. The frame has a flange to mate with a surface of the intake opening's interior flange. In one embodiment, two identical side panels are assembled with the relatively stiff end panels of a particular filter element to form the frame.
