Had something of a similar reaction but the note about far-UV not having the same problems as other UV serilization (i.e., also harmful to humans) I gather the point is about locality. UV in ducks will kill viri in the air system. But the spread of an airborn illness goes host-to-target before it passed through the air system.
As such seems that while the in-duct UV solution would help limit spread, it’s not going to do much to clean the air in the room while people are in it exhailing, coughing or sneezing, talking.…
I suspect it does little to protect the people directly next/in front of a contagious person but probably good for those practicing that old 6 foot rule (or whatever the arbitray distancing rule was).

Just my guess though.
