ABSTRACT:
A room air cleaner draws ambient air beneath a freely swinging baffle suspended above a liquid bath. As the air passes beneath the baffle, it is directed toward the surface of the bath. The momentum of the solid particles within the ambient air carries the particles into the bath where they are trapped and maintained. The air is then drawn through a filter element and subsequently exhausted into the room. An anti-splash screen prevents entrained liquid from being exhausted along with the stream of filtered air, while a separate reservoir together with a float valve mechanism may be utilized to maintain the liquid bath at a constant level, offsetting any liquid evaporation.
