【52KHZ DEEP ULTRASONIC CLEANING】 Experience professional-grade cleaning at home with high-frequency 48kHz ultrasonic waves. Millions of nano-scale bubbles penetrate every gap of your retainers, dentures, aligners, mouth guards, braces, toothbrush heads, and jewelry, gently removing buildup and stains with a powerful cavitation effect. 【UV Deep Cleaning】 The retainer cleaner has 4 UV Lamps for 720° deep cleaning. UV Lamps can eliminate odors, and the cleaning degree is 3 times that of a toothbrush. When the lid is opened, the UV Lamps will automatically turn off to protect your family's eyes and skin from harm. 【LARGE 200ML TANK & WHISPER-QUIET OPERATION】 Spacious 200ML water chamber accommodates most dental appliances without repositioning. Runs quietly below 40dB for a peaceful cleaning experience at home, office, or while traveling. Compact design fits any countertop or luggage. 【Double Hole Design & Low Noise】The top cover of the retainer cleaner has 2 holes, which can not only clean toothbrushes and makeup brushes, but also effectively dissipate heat and ventilation, and increase the life of the retainer cleaner. The operating noise of the retainer cleaner is less than 40 Hz, bringing you a quiet cleaning experience. 【GIFT-READY & WORRY-FREE SUPPORT】 Sleek, modern design makes it a perfect gift for family and friends.
