Abstract: This invention is a compact gas purifier useful as a home air purifier. Gas scrubber action is achieved in a specially shaped bowl partially filled with liquid. A central rotor drives the liquid by centrifugal force out and up the wall of the bowl to a re-entrant rim which directs the liquid back into the central region of the bowl in a spray. Gas to be purified is drawn in over the rim of the bowl, down through the spray of liquid and up out through a central cylindrical tube which surrounds the top of the rotor.
