What is the technology behind UV purifiers?
UV light, or ultraviolet light, is a form of electromagnetic light that is invisible to the naked eye. The main source of UV light is the sun.
There are three types of UV light: UV-A, UV-B, and UV-C. UV-A light has the largest wavelength, ranging from 315-400nm and UV-C light has the shortest wavelength, from 100-280nm.
Because UV-C light has the shortest wavelength, it also has the most energy and is the most effective at destroying viruses and other microbes.
Even though UV-C light has been used for killing germs for over 50 years, scientists are only now beginning to understand how it works so well.
DNA is made of up 4 nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). When UV light hits DNA, it knocks an electron loose and causes two T molecules or two C molecules to bond together, creating errors in the strings of DNA. Fortunately, humans have some genetic self-repair mechanisms to minimize UV destruction, but SARS viruses, the viruses that cause coronaviruses, do not.
Although the genetic material of the COVID virus is made up of RNA, not DNA , the effect of UV-C is essentially the same: UV causes genetic damage and the virus is destroyed.
