Abstract
The subject invention relates to combination lighting and air filtration units that provide illumination and filter air in a particular area. A lighting unit includes an illumination element and a housing with a rounded profile that encloses the illumination element. A conduit is adjacent to the housing wherein a filter is mounted within the conduit. An input fan draws air through the filter to produce filtered air and an output fan expels the filtered air.
