Abstract
A folding filter frame includes two end assemblies, each having a stationary panel having two ends, two folding panels, each having a folding end and a free end, and at least one track. The folding end of each folding panels is foldably secured to one of the ends of the stationary panel and the track runs perpendicular to a length of the end assembly. There is a stationary support extending from one end assembly to the other end assembly. Two side assemblies are present, each including a side panel with two ends and a engagement device secured to each end. The engagement device follows one the tracks of the end panels. The filter frame converts from a folded configuration to a deployed configuration by unfolding the folding panels and sliding the engagement devices in the tracks. A filter is made by positioning a filter media inside the folding frame.
