An independent test showed that this system deodorized and refreshened garments by reducing bacteria in them by 97%. The device generates O3 using a patented CPZ filter, neutralizing germs and bacteria, the sources of bad odors enmeshed among the fibers of clothing. Garments are hung with the device in the included garment bag; its built-in fan circulates O3 throughout the garments and the included scent packet, removing odors such as smoke, perfume, and perspiration in as little as 40 minutes. Includes four C batteries. 13 1/2" L x 10 1/2" W x 7" D. (41 /4 lbs.)
