An ultraviolet mask is a mask that uses ultraviolet (UV) light to disinfect and kill germs, bacteria, and viruses. These masks are equipped with light-emitting diodes (LED) or UV lamps that produce ultraviolet light. UV-C light with a wavelength of 100 to 280 nm is commonly used for this purpose because it can effectively destroy the DNA and RNA structure of microorganisms and inactivate them. These masks may be designed in medical, laboratory settings or even for personal use to prevent the spread of infections. It is important to be careful when using these masks, because ultraviolet light can be harmful to the skin and eyes, and direct contact with this light should be avoided.
