So funktioniert UV-C Licht als Virenkiller

Many metabolic processes in plants, animals and humans would not be possible without sunlight and the involvement of UV light. The very short-wave UVC light, which cannot penetrate the earth's ozone layer, is known as a virus killer.
Air, surfaces and also water can be made virus and germ-free using UVC light. It has been used for disinfection in surgery rooms for almost 40 years. UVC light has also been used for decades by the water treatment and food industry. The application is free of chemicals and this is particularly important, in order for the viruses and bacteria to not develop any resistance. UVC light is even recommended by the WHO to combat SARS-CoV-2.

This is how the virus killer works

The part of the UV spectrum relevant for disinfection is the UVC range between 200-280nm. The short-wave UVC light with 254nm wavelength penetrates through the shell of viruses. A chemical reaction is caused in the RNA of the virus, which deactivates compounds in the genome. This will stop the virus from multiplying. The viruses are practically eliminated. Not only viruses, but also bacteria, yeast, germs and fungal spores can be inactivated / killed by UVC radiation.

The lipid membrane of viruses is the easiest to penetrate. Fungal spores can require hundreds of times the dose of a virus. UVC light is not only effective against SARS-CoV and MERS-CoV viruses, but also against influenza, measles and mumps causing viruses and tuberculosis bacteria.

The necessary dose of UVC varies depending on the microbial group and relative humidity (RH).

Please note: If the LumeeLamp is used correctly, UVC light poses no risk. However, the open exposure to UVC is harmful to skin and eyes. Skin redness and conjunctivitis can be triggered.
