Abstract
An improved air filter having a frame that permits collapse and compression of the entire filter to save costs associated with transportation and for other advantageous reasons. The ends of the filter frame open to permit collapse of the frame to reduce the volume thereof. The filter frame is made of frame members at opposing frame ends, and each frame member has web panels that open for collapse of the frame, and close for construction of the useful frame. The web panels have legs on opposite lateral edges to form a channel in which filtration media is inserted, and four frame members are attached at opposing ends to form a rectangular frame. The web panels open by removing a temporary fastener, such as adhesive, or by other means.
