Superior Option

Krypton Far UV (222 nm) light provides an effective, autonomous, and continuous pathogen inactivation1 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.


Krypton Far UV (222 nm) light does not penetrate beyond the outermost nonliving layer of human and/or animal skin or eyes. While conventional UV-C lamps or LEDs (typically operating at 254nm or 270nm) commonly available today are much safer than sunlight, they can still penetrate to living cells and potentially be harmful to the skin and eyes with extended exposure. As a result, those UV-C systems are typically not utilized to sanitize whole room occupied spaces. Krypton Far UV (222 nm), in contrast, can sanitize whole room occupied spaces without those same risks.

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 pathogens1 but also destroy the proteins that the pathogens1 are made up of and also because they provide a more permanent inactivation or kill mechanism (whereas 254nm UV-C can often allow pathogens1 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 nonliving skin cells in the stratum corneum or the epithelial cells in the eyes.
