Superior Option

Krypton Far UV (222 nm) light provides a safe, effective, autonomous, and continuous disinfection system for occupied spaces. While the most common current alternative for sanitation in occupied spaces requires workers to wipe down chairs, counters, and any other surface between contact with each individual, it is not practical in practice, puts those workers at risk, and is subject to human error, like missing spots. Not to mention, wiping surfaces down does not address the airborne threat at all.

Safe for Humans

Krypton Far UV (222 nm) light does not penetrate beyond the outermost layer of human and/or animal skin or eyes. UV-C lamps commonly available today are known to be carcinogenic and harmful to the skin and eyes with extended exposure. As a result, UV-C lamps are typically not utilized to sanitize occupied spaces without risking adverse effects and long-term human tissue damage. Krypton Far UV (222 nm), in contrast, can sanitize occupied spaces without those risks to adverse effects to human tissue.

Effective for Sanitizing

Krypton Far UV (222 nm) lamps are often advantageous over existing UV-C disinfection systems (typically operating at 254nm or 270nm) in occupied spaces as they can be utilized in the respiratory zone where the contamination event occurs, because they not only inactivate the DNA of the pathogens but also destroy the proteins that the pathogens are made up of and also because they provide a more permanent kill mechanism (whereas 254nm UV-C can often allow pathogens to be photoreactivated by UV-A or blue light, which is emitted by sunlight, fluorescent lights, and other light sources after a disinfection cycle).

The 222nm Far UV Difference

Research has shown 222nm Far UV Lighting to be Safe for Human and Animal Exposure

Although Krypton Far-UVC (222 nm) light can penetrate and kill bacteria such as MRSA, it is unable to meaningfully penetrate the dead skin cells in the stratum corneum. UV from conventional 254nm lamps can penetrate and damage sensitive cells in the epidermis.

Far UV (222 nm) Krypton Disinfection Lights Completely Destroy Bacteria and Viruses

Krypton Far-UVC (222 nm) lights completely eradicate single-cell organisms, with less energy and with no photoreactivation. Krypton light primarily kills microbes by resonating with the proteins in the microbe’s outer membrane causing it to fail, rather than just the DNA itself.

Note: Far UV Technologies does not recommend the use of RT-PCR testing to confirm disinfection efficacy after treating with Far UV as the technique does not accurately measure “viable” SARS-CoV-2 contamination.  It only detects whether a particular type of RNA is present and not whether it is infectious.
