How Does Krypton Far-UVC (222 nm) Work?

Superior Option

Krypton Far-UVC (222 nm) light is the first safe, effective, autonomous, and continuous disinfection system for occupied spaces. While the best current alternative for sanitation in occupied spaces requires workers to constantly 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-UVC (222 nm) light does not penetrate 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. They cannot sanitize human tissue or occupied spaces without causing adverse effects and long-term damage.

Effective for Sanitizing

Krypton Far-UVC (222 nm) lamps are superior to existing UV sanitation systems (typically operating at 254nm) in occupied spaces for a very simple reason: Legacy UV-C sanitation systems are ineffective at disinfecting surfaces and air in occupied spaces because the kill mechanism allows pathogens to be reactivated by UV-A light, which includes sunlight, fluorescent lights, and other light sources after sanitation.

The 222nm Far UV Difference

Krypton Far-UVC (222 nm) lighting is much safer for humans and animals

222nm Far UV (safe) Compared with 254nm UVC Light (unsafe)

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

Krypton Far-UVC (222 nm) disinfection treatment completely destroys bacteria and viruses

UVC Virus Deactivation vs. Kill Mechanism using 222nm Far UV Technology

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.
