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.  

The majority of UV disinfection that is currently in use leverages UV-C light, which, while effective, can present some dangers. 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.

Where Far-UV Sterilray™ Can Be Used

Like UV-C disinfection, Far-UV Sterilray™ has a wide range of applications. One of the most common uses of UV-C disinfection is in the treatment of water, since water can easily be circulated to maximize exposure to the light. Far-UV Sterilray™ can also be used in this capacity, with the added benefits outlined above.

Of course, hospital construction and infection control represent an enormous opportunity for the use of Far-UV Sterilray™ because both disinfection and time are so critical. Far-UV disinfection means that entire rooms can be disinfected in a matter minutes while presenting no danger to staff.

Beyond healthcare, food manufacturing facilities are also in constant need of disinfection and Far-UV Sterilray™ can provide this service without speeding the aging process for machinery like UVC disinfection can.
