POWERFUL CLEANING: The shoe deodorizer emits ultraviolet light at 185 nanometers, which helps convert oxygen in the air into ozone. Ozone has high oxidizing properties that can break down odors and harmful substances in the air, leaving shoes fresher. EFFECTIVE PROTECTION: To maintain foot health, it's important to keep shoes dry and free from odor. The ozone generated by this device helps reduce shoe odor and prevents dampness, helping to keep footwear fresh and clean. ODOR ELIMINATION: Effectively dries shoes and reduces unpleasant smells, offering care for your footwear and helping extend its lifespan. The deodorizer features a long-lasting UV lamp with an 8000-hour lifespan and a screw-type bulb design. Helps keep shoes fresh between uses. THREE TIMING MODES: Mode one allows manual on/off control. Mode two runs for 15 minutes and automatically shuts off. Mode three runs for 30 minutes and automatically turns off. This allows convenient, timed drying and deodorizing.
