Abstract: A device for minimizing ambient pollution attendant to the cleaning of an airbrush includes a small box having a centrally located front opening for seating the air brush spray tip and a rear exhaust opening. The top wall is movable to an open position to permit replacement of rectangular filters which are releasably retained in longitudinally spaced positions by channels located on the box interior side faces, the filters being hydrophobic and of successively finer porosity and delineating between them successive diffusion and particulate matter precipitating chambers. The airbrush tip is seated in the inlet opening and actuated with a cleaning fluid which removes particulate residue from the airbrush and deposits it on the walls of successive chambers and on the filters.
