    How Does Ultraviolet Sterilization Work? Ultraviolet light is split into several different ranges: (near the visible light range) UV-A, UV-B, UV-C, Vacuum-UV (near the x-ray range). The UV-B range is what causes sunburn on humans. UV water purifiers use the UV-C range because of its germicidal abilities. Prolonged exposure to UV light helps ensure complete kill-off of all microorganisms. Unlike chemical treatments, however, UV-treated air or water does not resist re-contamination 1. Why Use UV Light Sterilization. Ultraviolet light penetrates the cells, but does not alter the water, air or food being treated.
