Title: Air filter construction

Abstract: A plurality of separate V-shaped wire mesh members are arranged and connected in side-by-side relationship to provide a plurality of V-shaped cells across an air stream. A W-shaped retainer or connector formed of perforated sheet metal has outer, downstream facing trackways which receive side edges of the wire mesh members, and a central, upstream facing trackway which receives and retains the free edges of V-shaped filter media bags which are inserted into the V-shaped cells overlying the wire mesh. A stabilizer bar extends across and attaches to the exposed adjoining edges of the V-cells to support the cells in proper relation and retain the filter media in place.
