Freshen your footwear with the Deodorizer Module. How it works: To eliminate odor, the PEET Deodorizer Module utilizes molecular science. Regular oxygen molecules are given a small electrical charge. This creates ozone molecules. A strictly controlled amount of ozonated air is dispensed inside the footwear. When it comes in contact with odor and pollution molecules, the ozone molecules penetrate them which destroys the bad molecules by altering their chemical make-up. Dry Responsibly with PEET.
