The best way to protect against Covid-19 and other airborne illnesses is to take the recommended health precautions of washing hands, social distancing and wearing a mask. Some people are also concerned about the objects that they touch and have considered using UV light sanitizers for their mobile phones to keep themselves safe.
Many have questioned whether UV mobile phone sanitizers work. UV (or ultraviolet) light is a form of electromagnetic radiation that is produced naturally by the sun. It can also be created artificially using specialized light bulbs. UV products are sold as sanitizers (which can reduce the number of germs on the surface of an object) and are different to disinfectants which have been shown to eliminate Covid 19 if the correct disinfection agent is used. It’s important to note, however, that contact with objects is not how Covid 19 is most often spread.
