Combine the proven drying power of The PEET Original paired with O3 odor removing science of our new D'Odoriz'r Module for the driest & freshest footwear and gear! How it works: To eliminate odor, the PEET D'Odoriz'r 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. This product is proudly made in the USA. Dry Responsibly with Peet.
