A hydro air filter for a dump bucket employed in a wet or dry vacuum system is formed by a single, vertical, closed tube with a transverse vertical dividing wall forming parallel vertical flow paths, the single tube having an opening at the top to one side of the dividing wall to sealably receive the dirty fluid return from the vacuum cleaner wand by way of an inlet tube which projects through the dump bucket side wall. The bottom of the dividing wall terminates short of the bottom of the tube to form a reduced cross-section, high-velocity flow area in proximity to one or more apertures within the tube, permitting aspiration of liquid within the dump bucket. The nozzles at the upper end of the single, closed tube open to the dump bucket interior to permit discharge of the return fluid and aspirated liquid for impingement on the inner wall of the dump bucket and separation of the liquid and gas components.
