Apparatus and method for treating impurities in air and materials

An apparatus for treating air, comprising:

• an enclosure enclosing an air treatment zone, the enclosure including an air inlet and a removable cover on a cover side and an enclosure outlet on an end wall;
• an ultraviolet (UV) light source enclosed within the air treatment zone and configured to generate ozone from the air, wherein the UV light source is disposed between the air inlet and the enclosure outlet, and UV light from the UV light source and the ozone generated by the UV light source treat the air in the air treatment zone;
• a catalyst housing connected to the enclosure at the enclosure outlet, the catalyst housing enclosing an ozone removal zone, wherein the ozone removal zone is positioned downstream of the air treatment zone with respect to a flow direction of the air being treated;
• the ozone removal zone comprising a first catalyst section with a first catalyst, a second catalyst section with the first catalyst or a second catalyst, and an air distribution spacer positioned between and separating the first and second catalyst sections;
• and
• an air outlet and an air mover positioned downstream of the second catalyst section and configured to draw the air through the air inlet into the air treatment zone from outside the enclosure, moving the air through the air treatment zone and the ozone removal zone, and then emitting the air through the air outlet out of the apparatus.
