That would treat the ducted air but it wouldn't treat the air already in the room. And if the air is being recycled, it would still linger for some bounded time

That would treat the ducted air but it wouldn't treat the air already in the room. And if the air is being recycled, it would still linger for some bounded time before being pumped back through treatment.
Having the UV in the room with the people means it treats every breath immediately.
- DannyBee 5y agoIt's not quite that simple - the lingering also depends on particle size (ie is it in a droplet, or bare, or ...) Most places with lots of people also have very high acph - often 20-30 air changes per hour.
