POWERFUL CLEANING: The shoe deodorizer emits ultraviolet light at 185 nanometers, which helps convert oxygen in the air into ozone. Ozone's high oxidation properties help break down odors and airborne contaminants, leaving shoes fresher. EFFECTIVE PROTECTION: Helps maintain foot hygiene by keeping shoes dry and reducing odor-causing bacteria. The ozone generated by the shoe cleaner helps eliminate unpleasant smells and supports a cleaner shoe environment. ODOR ELIMINATION: Effectively helps dry shoes and reduce odors, contributing to better shoe care and longevity. The deodorizer features a long-lasting UV lamp with a lifespan of up to 8000 hours and a durable screw-base bulb design. Keeps shoes fresh and clean. THREE OPERATION 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 shuts off. After the selected cycle ends, the device turns off automatically. Helps dry shoes at a consistent temperature to maintain dryness.
