Summary

Far ultraviolet-C light can reduce the level of airborne microbes in a room by more than 92%. Ordinary UVC light is very effective at destroying microbes like bacteria and viruses, it is hazardous for humans because it can damage skin and eyes. Far-UVC light with a 222 nm wavelength is too short to penetrate human skin or eye cells. Research suggests that far-UVC light can be safely used in occupied spaces, providing continuous disinfection without posing risks to human health. This technology could be a game-changer in the fight against airborne diseases, making it a crucial tool for public health.

Viability

The viability of far-UVC light technology is quite high given its potential to reduce the spread of airborne diseases without harmful effects on humans. The technology is still under development, but initial studies and pilot projects have shown promising results. Adoption may depend on further research, regulatory approval, and public acceptance.

Drivers

Several factors are driving the adoption of far-UVC light technology:

  1. Public Health Concerns: The COVID-19 pandemic has highlighted the need for effective airborne disinfection methods.
  2. Technological Advances: Improvements in far-UVC light sources and materials make the technology more feasible.
  3. Regulatory Support: Governments and health organizations are increasingly interested in innovative disinfection technologies.
  4. Economic Incentives: Reducing the spread of diseases can lead to significant healthcare cost savings.
  5. Public Awareness: Growing awareness of the importance of air quality and hygiene in public spaces.

Novelty

Far-UVC light technology is highly novel due to its unique ability to disinfect air and surfaces without harming humans. Unlike traditional UVC light, which poses health risks, far-UVC light operates at a wavelength that is safe for human exposure. This makes it a revolutionary approach to continuous disinfection in occupied spaces.

Diffusion

The diffusion of far-UVC light technology is currently at an early stage but is expected to grow rapidly. As more research confirms its safety and effectiveness, and as regulatory bodies approve its use, adoption in public buildings, offices, and other high-traffic areas is likely to increase.
