1. A method of forming a custom air filter, comprising:
providing an air filter comprising an outer frame formed from a plurality of frame members and a filter media arranged within the outer frame;
cutting at least one frame member of the outer frame and the filter media to form a cut air filter having a cut surface comprising at least one cut frame member and cut filter media;
providing a length of frame material comprising a substrate covered with a pressure sensitive adhesive, over which a release layer is disposed, wherein the frame material comprises a base that extends between two flanges;
folding the flanges of the length of frame material toward each other to form a substitute frame member;
removing the release layer from the substitute frame member to expose the pressure sensitive adhesive, wherein the release layer is removed after the frame material is folded to form the substitute frame member; and
pressing the substitute frame member into engagement with the cut surface of the cut air filter such that the exposed pressure sensitive adhesive bonds to the cut surface, thereby forming the custom air filter.
