Seems to do a good job for cleaning water, though this particular model may/not have a leaking issue. Oh, and the way UV light accomplishes the sterilization is via DNA destruction: "UVB light causes thymine base pairs next to each other in genetic sequences to bond together into pyrimidine dimers, a disruption in the strand, which reproductive enzymes cannot copy." So that's why it can kill viruses, because UVB light 'attacks' the DNA itself, stopping infection and mitosis. https://en.wikipedia.org/wiki/Direct_DNA_damage https://en.wikipedia.org/wiki/Direct_DNA_damage
