Are these products actually effective though? I mean the duration and intensity required to kill viruses in moving air must be quite high? Or is it just snake oil, like how a lot of hand dryers have bluish/purple LEDs (which emit no UV) that shine on your hands?
- culturestate 6y agoI can’t speak to their effectiveness in air, but they work very well for e.g. bacteria in rapidly flowing water. Aquariums have been using them for as long as I can remember.
- dreamcompiler 6y agoYes, they're effective. But near-UVC is dangerous to your skin and eyes, so it absolutely must be shielded. Far-UVC is quite safe to humans, and just as effective against coronaviruses, but it's rather expensive at the moment. https://www.researchsquare.com/article/rs-25728/v1 https://www.researchsquare.com/article/rs-25728/v1
