The COVID-19 pandemic prompted a surge of interest in technologies for removing viruses from the air, with far ultraviolet-C (UV-C), a wavelength that kills airborne pathogens, emerging as one of the front runners.

The development of COVID vaccines took the urgency out of this work, but far UV-C is still seen as a promising technology for pandemic readiness and preventing other infections, such as influenza, tuberculosis and hospital-acquired infections.

The technology itself is mature, but the market is not. Companies hoping to commercialise far UV-C systems face a range of barriers, from hesitancy in the healthcare sector to manufacturing costs that make mass deployment unattractive.

“Healthcare should be the…
