The shorter the wavelength of UV light, the more effective the light is at penetrating and destroying the bodies of pathogens. Therefore, while both Far-UVC and UVC are able to disinfect rooms and air streams of pathogens, the more effective, and safer light source is Far-UVC light. Far-UVC light is also less damaging to the plastic and rubber materials it comes into contact with. This makes it the more helpful option for healthcare facilities as it protects important equipment better than longer UVC light devices.
Far-UVC doesn’t penetrate human or animal skin, and is much less harmful. It also works much faster than UV-C and is more effective. Far-UVC light devices also don’t use toxic mercury in the bulbs, which helps protect people and patients from hazardous chemicals..
