Ultraviolet radiation air sanitizing machine

An ultra violet air disinfectant machine, comprising:

• (a) a cyclone separator having a housing reflective of germicidal ultraviolet radiation with at least one window therethrough transparent to ultraviolet radiation and defining a disinfection chamber, the cyclone separator configured and arranged for effecting a spiral vortex flow of air through the disinfection chamber about a longitudinal axis of the disinfection chamber from an inlet port proximate a first longitudinal end of the disinfection chamber for introduction of environmental air into the disinfection chamber proximate a first longitudinal end of the disinfection chamber to an outlet port proximate a second longitudinal end of the disinfection chamber opposite the first longitudinal end for withdrawal of disinfected air from the disinfection chamber proximate the second longitudinal end of the disinfection chamber and discharge of the disinfected air to the surrounding environment, the imposed spiral vortex flow operable for inertial concentration of microbes in the spiral vortex flow of air proximate a sidewall of the cyclone separator and past the at least one window, and
• (b) at least one source of germicidal ultraviolet radiation positioned external to the housing for emitting germicidal ultraviolet radiation into the disinfection chamber through the window.
