More than two years has passed since the epidemic began. The effects of epidemic control in many countries and regions have not been satisfactory.

Industrial disinfection alcohol requires a certain amount of manpower and material resources, and the ultraviolet lamp with a wavelength of 254 nanometers will cause certain harm to the human body and cannot continue to sterilize the environment. Therefore, there are currently two alternatives that are more popular with everyone.
- The first one is a germicidal lamp with a wavelength of 222nm. At this wavelength, ultraviolet rays cannot penetrate the stratum corneum of the human body, so there is no harm to the human body.
