Abstract: An UV air and surface disinfection apparatus comprises a housing with moveable or adjustable walls, an air chamber defining a passageway operable to receive air and direct the air in a predetermined direction, a plurality of ultraviolet light sources supported by the housing and arranged in a predetermined pattern around the air chamber such that, when the plurality of ultraviolet light sources are energized, the plurality of ultraviolet light sources project ultraviolet radiation outward to facilitate sterilizing air as it moves through the air chamber and when the walls are open, the ultraviolet radiation is further projected outwardly to an environment or area outside of the housing to facilitate sterilizing surfaces.
