Air filtration device
DCFirst Claim
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 filter supported in said air flow path;
an electric motor;
an 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, said impeller is driven by said electric motor; and
a pair of electric prongs extending outwardly from said rear surface for operational engagement with an electrical wall outlet for supplying electric power to said electric motor.

Abstract
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.
