About This

• Tired of scrubbing your retainers? UEOFEN delivers a thorough 360° clean, combining 50kHz ultrasonic waves with UV technology. It removes 99.99% of plaque and residue—3x more effectively than manual brushing. Works with or without cleaning tablets — use plain water for daily cleaning to save money, or add a tablet (not included) for an extra-deep clean when needed. Fresh, clean, odor-free retainers every time.
• Cordless and ready to use anywhere. Its 2×2000mAh battery delivers 70+ minutes of cleaning power—14 quick 5‑minute cleans or 10 deep 7‑minute cleans, enough for a full week of daily use on a single charge. Fully recharges in just 2 hours. For safety, it won't operate while charging and automatically stops if plugged in during use. Take it anywhere—home, travel, office. No cords, no limits.
• Never wonder if it's charged. The LED screen shows battery percentage down to 1%—so you always know exactly what's left. One button does it all: press once for a 5-minute quick clean, twice for a 7-minute deep clean. When done, it shuts off automatically—no waiting, no wasted power. Charging indicator glows while refueling. Simple, smart, worry-free.
• Designed for your retainer — and more. UEOFEN deep-cleans retainers and handles aligners, partial dentures, and jewelry just as well. The chamber measures 0.79" high x 3.58" in diameter, easily accommodating your retainer or aligner. Note: Not for full dentures or large mouth guards — always check your item's size first. So whether it's your nightly retainer or your favorite jewelry, one machine does it all.
• Compact & Travel-Ready: UEOFEN is beautifully compact — just 5.1" x 4.3" x 2.1" and 0.87 lb. It fits easily in your hand, your bag, or your suitcase. The lid covers the power button, so no accidental starts during travel. Includes a storage bag and tweezers for hygienic handling and easy storage. The tank rinses clean under water (do not immerse the whole unit) — effortless maintenance, day after day.
