A toothbrush sanitizer is a device used to disinfect the tooth brush by applying short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms. Studies in dental journals demonstrate that UV sanitizers effectively kill bacteria and microorganisms, but other forms of sanitizing, using common household products, were found to be equally or more successful at eliminating ...
A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing , causing formation of pyrimidine dimers , and leads to the inactivation of bacteria , viruses , and protozoans .
Within the sterilizer, water flows as close as possible to the ultraviolet light source. Water pre-filtration is critical as water turbidity lowers UV-C penetration. Many of the better UV sterilizers have long dwell times and limit the space between the UV-C source and the inside wall of the UV sterilizer device. [112] [third-party source needed]

UV-B, predominantly responsible for the harmful effects of sunlight, poses the highest risk for erythema, photokeratitis, sunburn and skin cancer. [14] [15] [16] While longer UV-C wavelengths and UV-A can also cause damage, their effects are less severe than UV-B. In contrast, far-UVC has shown remarkably different results.
