PURPOSE: To sent cleaned air efficiently be disposing the suction inlet of an air cleaner on the rear side of a stand while, disposing the blow-off port of said air cleaner on the front side of said stand, respectively.

CONSTITUTION: The contaminated air flows into a base 2 through a suction port 10 and the dust in the contaminated air is ionized by a corona discharge generating between a discharge electrode 38 and an opposite electrode 39. The ionized dust is adsorbed on a dust collecting electrode plate 36. Thus, it is efficient, since the air in the room is forced to be sucked and cleaned in an air cleaer 6. Moreover, since the cleaned air blown-off from the blow-off port 8 is blown toward a fan 17, it is sent to a distance with the wind blown by said fan 17.
