An ultraviolet sanitizer takes in micro-biologically unsafe water and treats it with germicidal ultraviolet light. This light will make changes to the DNA of various germs, so that the water becomes pure. When you ingest such clean water, no harmful microorganisms enter your digestive tract, thus helping to maintain good health.

Ultraviolet light works by eliminating viruses, bacteria, algae, molds, and other types of germs that can grow and multiply quickly, causing diseases of various types. The UV technology destroys the DNA of such germs so that they are unable to further propagate. The UV light is transmitted by a UV lamp that is present inside a glass quartz sleeve, which sends the germicidal radiation that has the capacity to deactivate a variety of living organisms.
