ABSTRACT:
This invention relates to improving the efficiency of air filter systems that incorporate adjustable air filter frames having telescoping frame sections. In such systems, an air bypass space exists between the frame and the filter frame support member in the air duct. This invention provides an air bypass clip that is inserted between the filter element contained in the adjustable air filter frame and the frame support member. The air bypass clip has a sealing lip which bears against the support member thus blocking the flow of bypass air between the adjustable frame and the support member.
