Abstract: An air treatment unit having a frame and a source of UV light, with the frame having an air guidance assembly. Air within a primary treatment volume is guided by the frame to move radially outwardly from the primary treatment volume through a dispersion angle. Air within the primary treatment volume is exposed to UV light rays from the UV light source. The air treatment unit is changeable between: a) a first state wherein a predetermined part of a volume of space within which the air treatment unit resides is strategically blocked from direct exposure to UV light rays generated by the UV light source; and b) a second state wherein at least a portion of the predetermined part of the volume of space is directly exposed to UV light rays from the UV light source.

Abstract: A method of treating an inside volume of a mobile vehicle including the steps of: a) obtaining a treatment system placed in an operative position with respect to the mobile vehicle and having: i) at least one UV light source; and ii) an air mover; b) operating the air treatment system in one state wherein surfaces within the inside volume are directly exposed to UV light rays; c) changing the air treatment system from the one state into another state so that at least part of the surfaces directly exposed to UV light rays from the at least one UV light source with the treatment system in the one state are not directly exposed to UV light rays; and d) operating the treatment system in the another state wherein air advanced by the air mover is disinfected by UV light rays from the at least one UV light source and distributed within the inside volume.

Abstract: A treatment apparatus and method of treating an inside volume of a mobile vehicle using the apparatus. The method includes the steps of: a) placing a treatment unit in an operative position with respect to the mobile vehicle, the treatment unit having: i) a frame; ii) a source of UV light; and iii) an air mover for controllably directing air within the inside volume to be exposed to UV rays generated by the UV light source; and b) operating the treatment unit and thereby causing air within the inside volume to be disinfected by UV light rays from the UV light source and circulated within the inside volume.

Abstract: An air treatment unit and method of treating air in a space using the air treatment unit. The air treatment unit has a frame and a source of UV light that is configured to generate UV light rays that disinfect air. The frame has a primary treatment volume and an associated air guidance assembly. Air within the primary treatment volume is controllably guided by the frame in a radially outwardly moving pattern while being exposed to light rays from the UV light source.
