An improvement to a reusable filtering assembly used in circulating air systems for residential or commercial heating and air conditioning systems. A series of layers consisting of filtering materials disposed between two framing units are comprised of the following: expanded metal lath, a layer of small fiber material, a layer of large fiber material, a layer of small crimp wire cloth, a layer of small fiber material, and a last layer of expanded metal lath. The present invention further comprises a stage loaded series of layers wherein the direction of...


What is claimed is: 1. A reusable air filter assembly for circulating air systems, comprising:a. a frame, comprising two frame units capable of sandwiching a number of layers of material, and each comprising a feature that overlaps the other, wherein a single screw can be disposed through the overlap to secure the frames relative to each other;b. a series of material disposed in the frame, containing a first layer of expanded metal lath, a second layer of small fiber material, a third layer of large fiber material, a fourth layer of small crimp wire clot...
