About the HLDM Care222 Technology 

Far-UVC light, specifically the 222nm wavelength, inactivates viruses and bacteria in short time periods at energy levels that do not penetrate the living tissue in skin or beyond the tear layer in eyes, allowing this UV wavelength to be used in occupied spaces. While the wavelength does not have enough range to penetrate deep into the skin and eyes, 222nm far-UVC light has enough range to traverse viruses and bacteria which are much smaller in size than human cells.
