The Efficacy of Far-UVC 222nm in Occupied Clinical Environments

Introduction to Far-UVC

Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses. While conventional UVC light (254 nm) can be used to disinfect unoccupied spaces, direct exposure to conventional UVC lamps is not possible in occupied public spaces as this can be a health hazard.

Methodology

In this study, we evaluated the efficacy of 222-nm UVC light for inactivating aerosolized pathogens in a realistic clinical setting. We continuously generated aerosols of pathogens in a room-sized test chamber and measured the inactivation rate of the airborne viruses when exposed to 222-nm UVC light.

Results

Our results demonstrate that 222-nm UVC light is highly effective at inactivating airborne human pathogens. The 222-nm UVC light produced a 99.9% reduction in the concentration of airborne viruses in just 25 minutes.

Conclusion

Continuous low-dose-rate far-UVC light in occupied indoor public places is a promising, safe, and inexpensive tool to reduce the spread of airborne-mediated viral diseases. ViKavach systems are optimized for exactly this frequency, ensuring a balance between sterilization efficacy and occupational safety.
