I just replaced my 26 year old HVAC system and i bought the hospital grade air purifier system with the new HVAC system. It uses UV, so I was ahead of the curve. Just installed in on February 15th.
You answered a question I hadn’t even asked yet. I imagine this would be invaluable in public places and businesses.
There are quite a number of after market UV devices for home HVAC (or furnace) on Amazon. Also stand alone UV air purifiers. There was a $29 UV bulb that sterilizes a room (remote on/off timer, no room occupancy during high UV output). The information for that one was an obvious Chinese translation.
What’s the brand name of the UV a/c purifier system, please?
