In this peer-reviewed article from Scientific Reports, it is shown for the first time that Far-UVC efficiently inactivates airborne aerosolised viruses, with a very low dose of 2mJ/cm² of 222 nm light inactivating >95% of aerosolised H1N1 influenza virus. Continuous very low dose-rate Far UV-C light in indoor public locations is a promising, safe and inexpensive tool to reduce the spread of airborne-mediated microbial diseases.
