On Air vs Fomites: for this virus, a picture is emerging that fomites are basically irrelevant and air transmission via droplets or aerosols is what matters. But in general, there may be other pathogens where fomites are most important, e.g. norovirus and the like that spread via the fecal-oral route.
UV light can help with fomites but a full solution to fomite problems requires other changes, such as copper surfaces, better ways of making large amounts of very hygienic food, etc.
On ventilation: ventilation won’t eliminate droplets from sick people, it will dilute them somewhat over time. Airplanes already have ventilation via a compressor.
Far-UVC can zap droplets that are in the air before they get from person A to person B, which I think is the big win here.
