Apparatus and method for treating impurities in air and materials

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 the atmosphere through an atmosphere treating unit;
• generating ozone within the atmosphere treating unit;
• mixing generated ozone with the atmosphere in the atmosphere treating unit;
• exposing the mixture of atmosphere and ozone to UV light in the atmosphere treating unit to remove at least a portion of the contaminants in the atmosphere;
• removing at least a portion of the ozone from the UV light-exposed mixture of atmosphere and ozone to form an ozone-depleted containing an amount of ozone below a preselected threshold amount;
• exhausting the ozone-depleted mixture into the enclosed space;
• recirculating at least a portion of the ozone-depleted mixture through the atmosphere treating unit to remove at least a portion of the contaminants remaining in the ozone-depleted mixture;
• and
• repeating said exhausting and recirculating steps until the ozone-depleted mixture exhausted into the enclosed space contains an amount of the contaminants below a preselected threshold amount.
