Title: COLLAPSIBLE PLEATED FILTER AND FRAME
Abstract:
A collapsible HVAC filter that includes a pleated filter media pack with ends that attach to ends of a planar filter frame member. The structure collapses by folding the filter frame member along score lines and compressing the pleated filter media while the media and frame member are attached. The collapsed components occupy little space relative to the expanded filter, and can be expanded to form a completed filter with little effort required by the end user. Most of the filter media is collapsed in a generally U- shaped channel formed from the folded filter frame member.
