At this time, sterilization of these public spaces is a major means for preventing infection of viruses and bacteria.
The use of uv generators to disinfect public spaces is a relatively easy and inexpensive method. The ultraviolet ray with proper wavelength acts on the virus or bacteria to destroy the molecular structure of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) in the cells of the virus or bacteria, so that the growing cells and the regenerative cells die, and the effects of sterilization and disinfection are achieved. The air is irradiated by UVC wave band ultraviolet light with certain power and intensity, so that bacteria, viruses, parasites, algae and other pathogens in the air can be directly killed, and the aims of sterilization and disinfection are achieved.
