In your home, you might consider something “clean” as long as it’s not covered in dust or grime. But in hospitals, food facilities, and other sensitive environments there is a lot more to cleaning than running a dust cloth over a surface.
Ultraviolet (UV) light has been used in disinfection practices around the world for years. Indeed, Arthur Downes and Thomas P. Blunt published a paper in 1878 describing the use of UV light on bacteria and the process has been used to disinfect drinking water since 1910. Recent developments in technology have made Far-UV Sterilray™ available to maximize the effectiveness and efficiency of UV sterilization, addressing some of the common problems found with older methods. UV Disinfection: An Overview UV disinfection, more officially known as ultraviolet germicidal irradiation, is hardly a new addition to the world of disinfection. In fact, using UV-C lights have been used for this purpose since the middle of the 20th century. UV-C lamps work on a physical level. Microorganisms like bacteria and viruses are rendered inactive by UV-C lights because of the way the light damages the nucleic acids of the cells. UV-C light has short wavelengths and high energy, which microorganism RNA and DNA absorb and by which they are destroyed, left unable to infect.

For instance, UV-C light can penetrate the skin and cause harm to humans that are present during disinfection. In addition, UV-C light causes the rapid aging of materials like plastic and rubber, making it a risk to use in some environments where sensitive and expensive equipment may be subject to these effects. How Far-UV Sterilray™ is Different Far-UV Sterilray™ is different from UV-C disinfection options because it utilizes a different wavelength of the UV light spectrum. Far-UV light has a shorter wavelength and higher photon energy than UV-C, making its effect on microorganisms different from UV disinfection lamps that are most commonly used. Far-UV light is able to cause physical destruction of viral, bacterial, and fungal cells in a matter of seconds, much faster than UV-C lamps. Further, Far-UV light is safe for use when people are present, which is not true of UV-C lamps. Far-UV Sterilray™ uses a wavelength of light that, according to the best available research, cannot penetrate the skin, protecting human cells when Far-UV Sterilray™ is in use. According to a study published in early 2018: "far-UVC light (207–222 nm) efficiently inactivates bacteria without harm to exposed mammalian skin. This is because, due to its strong absorbance in biological materials, far-UVC light cannot penetrate even the outer (non living) layers of human skin or eye; however, because bacteria and viruses are of micrometer or smaller dimensions, far-UVC can penetrate and inactivate them." Far-UV Sterilray™ is also made without the use of mercury, which is included in the bulbs of many UV-C lamps. The construction of the Far-UV Sterilray™ lamp means that it is safer both for use and for disposal than a similar UV-C lamp.
