UV Sterilizer COCOMM Highlights: Safe and reliable sterilization at 99% Protection against germs and pathogens Powered by USB port Portable High-performance lamp technology: optimized UVC radiation output of 253 nm (strong disinfecting action) Easy to use Description: Why use a UV sterilizer? A smartphone contains more bacteria than a subway handrail or a toilet bowl. According to an American study, there are over 7000 types of bacteria present on a phone. Among them, some are harmful to health, such as salmonella or golden staphylococcus. However, smartphones are not the only dirty objects that carry contamination: keys that go everywhere and fall on the ground, coins or banknotes, pens. How does it work? Ultraviolet radiation sterilization is a sterilization method based on the sensitivity of microorganisms to exposure to low wavelengths of ultraviolet light. UV-C has been used for decades as a germicide and bactericide. They can destroy microorganisms such as viruses, bacteria, and other pathogens: it is absorbed by the DNA of microorganisms and destroys their structure. In this way, living cells are inactivated. They are an excellent alternative to chemical products and have the advantage of being safe for humans as long as one does not directly expose oneself to the radiation.
