Patent ID: 8388900

Claim:
A method for at least one of sanitizing, decontaminating, deodorizing, conditioning and drying an atmosphere exposed to a material within an enclosed space, the method comprising: circulating a flow of the atmosphere containing a contaminant through an atmosphere treating unit; Passing the flow through a light baffle at a viewing angle to contain UV light in the atmosphere treating unit; generating ozone within the reaction zone; mixing generated ozone with the contaminants in the flow in the reaction zone; exposing a mixture of the contaminants in the flow and the ozone to UV light in the reaction zone to remove at least a portion of the contaminants in the flow; removing at least a portion of the ozone from the flow in a removal zone downstream of the reaction zone by catalytically decomposing the ozone with a catalyst comprising manganese dioxide and copper oxide to form an ozone-depleted mixture containing an amount of ozone below a preselected threshold amount; and exhausting the ozone-depleted mixture into the enclosed space.
