Air filtration device
First 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 and a rear surface;
at least one air inlet formed in said front surface;
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 impeller supported by said housing for moving air through said air flow path, said impeller including a central inside area;
a baffle plate supported by said housing for directing air flowing from said air inlet toward said central inside area; and
a motor for driving the impeller, the motor and impeller at least partially supported by the baffle plate.

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.
