A Safe Delta U+ Disinfection Device
Care 222® is a light source module that can inactivate bacteria and viruses with ultraviolet light emitted at the wavelength of 222nm. The 254nm wavelength ultraviolet rays commonly used are easily absorbed by DNA, which is bacteriostatic indeed, but it also exerts an adverse impact on human cells. The special, shorter wavelength of UV-C 222nm light, in contrast, is germicidal as it penetrates the DNA of viruses and bacteria. However, when irradiated on people, 222nm light will be absorbed by the stratum corneum of our skin before reaching the DNA of human cells. Conversely, longer wavelength of 254nm ultraviolet rays can penetrate the layers of our skin and cause damage to the DNA in our skin cells.
