The CleanAir product was designed to generate pure chlorine dioxide for placement inside of an enclosed area of no more than 53 ft. Under normal operating conditions (i.e., during exposure to ambient moisture during ice production at or below 0° and up 110°, Fahrenheit), a single CleanAir packet will provide clean air odor control and environmental cleanliness for up to 30 days. Additional packets may be required for larger enclosed areas.
