Quick answer

A UV water sterilizer is a water treatment device that uses ultraviolet light to deactivate bacteria, viruses and other harmful microorganisms. It destroys the DNA or RNA of pathogens such as E. coli, viruses and protozoa like Cryptosporidium and Giardia so they cannot reproduce, purifying water without the use of chemicals.
