Ultraviolet light is effective at killing bacteria, viruses, mold, algae, yeast, cysts (including cryptosporidium and giardia), some volatile organic compounds and other biological contaminants. Unlike chlorine, which is used in municipal water supplies to kill microorganisms, UV-C sterilization systems do not introduce any potentially poisonous components into your drinking water, or adversely affect the taste or smell of drinking water.
