Facts about UVC

Effective technology for disinfection

For more than 100 years, UVC light has been known to destroy microbial life, which thrives in closed, humid environments.

In 1903, Niels Finsen was awarded the Nobel prize for medicine and physiology for his contribution to the treatment of tuberculosis with UVC light.

UVC light is the shortest wave in the ultraviolet light spectrum. These short waves are able to penetrate cell walls and destroy the microorganism's DNA.

UVC radiation occurs naturally in the sun's rays, but it is absorbed by the atmosphere, so it never reaches the surface of the Earth like the longer waves of UV radiation.

What is UVC light?

UV occurs naturally in solar radiation. UVC is completely absorbed into the atmosphere and does not reach the surface of the Earth. UVB is absorbed to a large degree by  the ozone layer. UVA is not absorbed by the atmosphere, but it is disseminated like other light and therefore also reaches the surface of the Earth unabated. Ultraviolet (UV) light is a series of light frequencies, which are mostly invisible to the human eye. The UVC spectrum is effective at killing bacteria because the short length of the light waves makes them able to penetrate the cell walls of microorganisms. As a result of UVC being filtered out in the atmosphere and not hitting the Earth, the microbes do not have the ability to build up a natural defence against UVC light.
