ABSTRACT:
This invention provides an improved construction for air filters wherein the filter frame is provided with indentations or recesses adjacent to its opposite corners which allow a plurality of filters to nest together in a laterally offset relationship to conserve space. The invention can be employed with an air filter including a filter element of fibrous material and a frame for supporting the filter element at its marginal edges. A set of recesses is formed in the same face of the filter frame and located along adjacent sides of the frame at positions adjacent to its opposite corners. The recesses are spaced from diagonally opposite corners of the filter frame by substantially the same distance to permit a pair of filters to nest together in a laterally offset relationship for shipment or storage.
