The Oclean S1 Sterilizer prevents bacteria from settling on the toothbrush. Gold wave ultraviolet rays can eliminate 99.9% of bacteria. The UVC LED emits UVC light with high photon energy, destroying the molecular structure of DNA/RNA in bacteria and viruses, and killing active and regenerative cells to sterilize the surface of the toothbrush and brush head. Automatic sterilization occurs every 6 hours for 2 minutes, making the device smart and convenient. A user-friendly blue indicator light serves as a reminder to avoid UV exposure. It includes two sets of LED lights, UVC, and a blue display. Since UVC is invisible, the blue LED is meant to remind users that the device is in operation.
