An air filtration device for intake of atmospheric air, removal of contaminants from the atmospheric air, expulsion of filtered air, includes a housing configured for application directly to an electrical outlet and provides air intake from the front surface of the housing and air expulsion from the side of the housing to utilize a wall surface to disperse the filtered air. An indicator is provided to communicate that a filter should be changed, and a filter orientation system is provided to allow proper orientation of the filter with respect to air flow.

[ We claim:] [1.]1. An air filtration device for intake of atmospheric air, removal of contaminants from the atmospheric air, expulsion of filtered air and configured for operational association with a generally vertically oriented surface, said air filtration device comprising:a housing defining an air flow path therethrough and having a front surface, at least one side surface and a rear surface;at least one air inlet formed in said front surface of said housing;at least one air outlet formed in said housing intermediate said front surface and said rear surface, for cooperation of said air outlet with a generally vertical surface to which said air filtration device is associated for enhanced dispersion of filtered air expelled through said air outlet;a generally planar filter supported in said air flow path and being selectively removable from said housing, said filter including a notch formed therein for directing insertion of said filter in a correct orientation with respect to said air flow path; and impeller for moving air through said housing along said air flow path from said at least one air inlet to said at least one air outlet, said impeller being supported within said housing.
