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.
