About two or three weeks ago I was thinking about all the absurd regulations in place to reopen businesses.
In my thinking I came up with a idea that might work very well.
Back in March I had to put in new HVAC unit for my upstairs, I had put in a a new downstairs unit in four years earlier.
Well the HVAC guy told me that included with my new unit was a UV Light Filtering system. Since I am downstairs more than up I had him put UV system on the downstairs unit.
According to the HVAC guy it kills all germs and viruses in the house, in the air and on surfaces.
So perhaps businesses should put that UV filtering system in, especially restaurants and bars. That should eliminate the need for masks and these places to open back up to full capacity and comply with the various state health departments.
In addition put in a UVC Light system at the entrances where the customers have to pass through it, That would also kill any germs and viruses they have on them.
Please comment and give pros and cons on this, and no flaming me please.
Fyi. This is already pretty common.
Well you don’t seem to hear about it much. If I had such a system in place I would advertise it.
I think the problem is scale and safety. You can’t have uv in folk’s eyes. So while it is great at killing germs through the ventilation, it would do little to nothing for surfaces without being dangerous.
was this installed in the supply plenum? how much were you charged if you don’t mind answering? i was told around $1000 which seemed lot? and my technician talked about it creating an ozone smell?
see this link for potential dangers:

“UV-C Light
Air purifiers that use ultraviolet light to kill microorganisms (also known as UVGI, ultraviolet germicidal irradiation) only work against certain species. More importantly, they may also have a hidden danger. Small home UV-C air purifiers use a fan to blow air through the purifiers, where pollutants are briefly exposed to UV light while passing through. The hidden danger is not from the radiation (although you do need to be careful when using UV-C light). The danger comes from oxygen particles that are broken apart by the high-energy UV-C light. These atoms then combine again with other oxygen atoms to form ozone. Therefore, UV-C air purifiers are not ozone-free.
Not only do they produce ozone, they are not very effective in a residential setting. While studies have shown that high-energy ultraviolet light kills bacteria, viruses and some mold spores, to do so effectively requires very high-intensity UV light and a long duration of exposure. So these units offer neither the intensity nor duration necessary to be really effective. Plus, they do nothing to remove particles like dust from the air, so they have to be combined into hybrid systems with HEPA filters.”
I did not buy it separately, it came with a unit I bought, I just asked them to out it on my downstairs unit.
It seems to work fine and if it gives me any help at all it’s worth it.
The UV light won’t kill in the time it takes for someone’s cough Townsend the virus to you.
In my area a local oral surgeon just had these units installed in his offices. It seems these have been used in medical facilities for some time.

I’ve had a similar thought, but it involved aircraft.
When it is used in a room environment, it is set up to turn off when the room is inhabited due to eye damage.
In addition, UVC is very hard on plastics and pigments.

I installed an aftermarket Swordfish unit in my HVAC
Thanks for the heads-up.
I just submitted a patent for the idea.
I use a 44 watt UVC cabinet for sterilizing and it stinks up the room because of the ozone. You don’t want to irradiate customers and you don’t want them to think your business stinks. The units are OK in ducts since the air gets moved and dissipates the ozone, but really these are made more for problem spaces, like surgical suites or homes located where mold is a constant problem. I wouldn’t put it in a location that didn’t need it.
And when they cause cataracts who pays?
The HEPA system is more useful than the UVC component.
I can’t believe you are suggesting we inject HVAC systems into our bodies. If any Freepers die trying this cockamamy cocktail of yours it’s on your hands mister!

Medical supply manufacturers use UV all over the place. I went through a suture manufacturing plant in the mid 1990s and the final step before boxing was running the line under UV lights.
Ozone is problematic too.
