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.

A pair of identically formed facing sheets are joined along opposite side edges and include a fiberglass core therebetween. Each of the facing sheets includes a central web section, a side wall extending inwardly from each side edge thereof, a first flange extending inwardly from the free edge of one of the side walls and a second flange extending outwardly from the free edge of the other of said side walls. Both flanges are substantially parallel to the central web section. The pair of facing sheets are positioned opposite each other and with the first flange of each sheet adjacent the second flange of the opposite sheet. A support member is inserted in the space formed by the inwardly extending flange, adjoining side wall, and opposite section of the central web. Finally, the flanges are joined with fasteners, with a strip of heat non-conducting, material inserted between the adjoining flanges of the facing sheets when assembled to minimize transfer of heat and/or prevent flow of current from one facing sheet to the other. In joining one of the aforementioned building panels to an adjacent panel, the panels are positioned together with a side edge of one in overlapped relationship with the corresponding edge of the other.

A generally conventional air washer is modified by dividing the water delivered to a bank of sprays into a first portion that is directed to a header at the top of the bank and a second portion that is directed to a header at the bottom of the bank. A throttling valve is placed in the line upstream of the upper header. When the air washer is being used as a dehumidifying apparatus, as in summertime use, and during situations of minimum use as a dehumidifier, the water supply to the upper headers may be throttled or even cut off completely without affecting the water pressure to the lower header. Water from the lower nozzles in such situations continues to be emitted into the air stream as an atomizing spray.

An elongated, generally U-shaped in cross-section, retainer strip, of the type which includes longitudinally extending, resilient, confronting semi-walls extending inwardly and downwardly from the free ends of the legs to grip the edges of a fibrous filter mat, includes a pair of exterior flanges. One exterior flange extends in spaced, parallel relation to one of the walls of the retainer strip to mount the retainer strip on a planar portion of a filter frame without rivets or cement. The other exterior flange extends in spaced, parallel relation to another wall of the retainer strip to secure the edges of a conventional screen or mesh backing member eliminating sheet metal tabs.
