That’s a very different product, using UV inside HVAC systems as an alternative or supplement to traditional filtration. Because the delivery rate of HVAC as a fraction of all air in the room is so much lower than the fraction air above people in a high ceiling room, this is much less valuable.
Very roughly, the main ways people use UV to clean air to reduce spread of diseases are HVAC / in duct, far UV, and upper room. I’m only trying to talk about the last of these here.
