UV-A light is much more efficient than UV-C light and is therefore much more suitable for the filter technology photocatalysis, in which 99,9% of all organic substances such as viruses and bacteria are sustainably destroyed. Moreover, unlike UV-C light, air purification with UV-A light is not harmful to humans and handling it is not dangerous. Also, unlike UV-C light, air purification with UV-A does not release ozone. The AiroDoctor has powerful LED modules that can produce a UV-A wavelength of 385nm (nanometers), which is optimal for photocatalysis.
