  • “Based on our results, continuous airborne disinfection with far-UVC light at the current regulatory limit could greatly reduce the level of airborne virus in indoor environments occupied by people,” remarked by David Brenner, PhD, Higgins Professor of Radiation Biophysics at Columbia University.

  • Research by Dr. Ewan Eadie about Far-UVC skin safety indicates that “estimates that 10 minutes of sunlight exposure are equivalent to more than 3 years of exposure to filtered Far-UVC lamps”.

  • On December 17, 2021, World Health Organization(WHO) held a webinar in which some top scientists highlighted the advantages of 222nm Far-UVC, recognising and promoting the incredible potential of applying this technolgy to fight the pandemic.

The Science of Safe, Continuous Protection

222nm Far-UVC light is scientifically recognized as safe for human exposure, as its energy is absorbed by the outer, non-living layers of skin and eyes, preventing harm to living cells. Our technology enhances this inherent safety with an integrated optical filter. This critical component removes over 99% of accompanying non-222nm wavelengths, ensuring the output is exceptionally precise. You benefit from a sanitizing spectrum that is both highly effective against pathogens and optimized for safety in occupied spaces.

Artificial UVC

The ozone layer absorbs all UVC light from the sun, preventing it from reaching the Earth’s surface. With technologies and efforts, UVC can be created artificially. And so we can utilize this incredible disinfecting tool in our daily life.

You may wonder why don't we just use UVA/UVB for germicide?UVC, which is higher energy, has a far higher germicidal function.

Is It safe?

Common UV lamps and LEDs give off light with wavelengths either 254 nm(Low-pressure mercury lamp) or 266 nm(UV-LED). While these are effective germicidal tools, they pose dangers to human skin and eyes if exposed too directly or for too long.  

Far-UVC light, with wavelengths from 207 nm to 222 nm, can still inactivate bacteria and viruses. But does not penetrate human tissues as deeply as other types of UV light, so your eyes and skin will not be damaged.

Effect on the Eyes

Looking at UV light is as dangerous as looking at the sun directly. UVA, UVB, and UVC light can lead to cataracts, macular degeneration, damage of the retina, and other eye conditions.

Far-UVClight does not penetrate the tear layer as other types of UV light, therefore it's safe to even look into it directly.
