Abstract: An air scrubber and method for cleaning a stream of air utilizes a horizontal tray (A) together with a passageway (B) for transporting air beneath the trays and directing same upwardly through a perforated bottom of the tray which is supplied with a predetermined level of water which flows over a weir from a suitable source (C) wherein the upwardly directed air agitates the water resulting in a scrubbing action which is then followed by the action of an eliminator section (D) which removes water remaining in the air stream after agitation and scrubbing.
