Technology that Redefines Oral Hygiene
Experience precision-engineered ultrasonic and UV-C cleaning designed to eliminate 99.9% of bacteria while preserving the beauty of your dental devices.
Your aligner, retainer, or dental appliance deserves professional-grade hygiene every day. COJA combines advanced ultrasonic vibration with UV-C sterilization to deliver a deeper clean faster, quieter, and more efficient than manual soaking or brushing.
Ultrasonic Waves Meet UV Sterilization
48,000 Hz Ultrasonic Vibration
Breaks down microscopic plaque, stains, and residue with powerful yet gentle vibrations.
UV-C Light (265 nm)
Neutralizes bacteria and viruses with hospital-grade precision for complete sanitization.
360° Deep Reach — Every Curve, Every Edge
Traditional brushing and tablets clean only the surface. COJA's micro-vibration technology cleans every contour of your aligner or denture tray — reaching areas human hands simply can't.
Modern Energy, Minimal Waste
Powered by USB-C for universal compatibility and fast charging, COJA eliminates single-use chemicals and wasteful tablets. Built with long-life components to reduce replacement frequency — good for your health, and the planet.
Soft on Materials, Powerful on Cleaning
