Microbes have to spend some time in front of the UV light before theyвЂ™re destroyed. In fact, The World Health Organization (WHO) has issued a warning against people using UV light to sterilize their hands or any other part of their skin. Special training and equipment are required to use UVC technology safely.

If your eyes are exposedвЂ¦ you know that gritty feeling you get if you look at the sun? ItвЂ™s like that times 10, just after a few seconds.вЂќ he said. вЂњIt can take hours to get sunburn from UVB, but with UVC it takes seconds. The UV-C radiation itself is also a concern if improperly handled.Дan Arnold, a scientist at UV Light Technology in the UK warns of the dangers of UV-C purifiers for home use. Even very small amounts of ozone in the air may result in chest pain, coughing, shortness of breath, and throat irritation. The biggest issue with UV purifiers is that they emit varying levels of ozone. Fortunately, humans have some genetic self-repair mechanisms to minimize UV destruction, but SARS viruses, the viruses that cause coronaviruses, do not.ДЄlthough 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. 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. UV-A light has the largest wavelength, ranging from 315-400nm and UV-C light has the shortest wavelength, from 100-280nm.Д«ecause UV-C light has the shortest wavelength, it also has the most energy and is the most effective at destroying viruses and other microbes.Д®ven 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.ДNA is made of up 4 nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). There are three types of UV light: UV-A, UV-B, and UV-C.

UV light, or ultraviolet light, is a form of electromagnetic light that is invisible to the naked eye. But what exactly are UV purifiers and do they live up to the hype? What is the technology behind UV purifiers?

UV light air purifiers or вЂњsterilization lampsвЂќ have been touted as being able to kill 99.9% of viruses, including COVID. The COVID-19 pandemic has increased awareness of the importance of clean air.
