Anti-Microbial UV systems

Yes i have some and my wife does seem less Moldy and less sick.

I am glad to hear that your wife does at least seem "less moldy" - LOL!!!

...I couldn't help myself  :-)

Thats fine i was trying to be funny ! see ya later

This sounds really great..never heard of it.  How would you even make your own?

I've considering doing this.  All you need is a UV light source shining in a space in the main duct of your heating & air conditioning system.  There will be questions along the lines of: is the light source intense enough and does the air pass through the illuminated volume slowly enough to be effective, I don't know the details of how to figure that out.  But UV light sources are easy to come by, a fluorescent lamp without the phosphor on the inside of the glass is just that, and UV LEDs are fairly common too.  So it could be as simple as adding a light fixture inside the main HVAC duct somewhere convenient and running power to it, put a UV bulb in the fixture and turn it on.

i have a similar set up in my well intake line; water passes through a stainless steel cylinder with a concentric glass tube inside, inside that tube is a uv bulb

What's keeping me from doing this is the fact that UV radiation reacts with air to produce ozone, and breathing ozone can be harmful. Ozone in the air does break down over time, so as long as you are not creating ozone faster than it can break down, you're probably okay. I went so far as to look for ozone meters, so I could be more certain of the ozone levels I might be creating with the UV bulbs, but was not able to find one for less than around $300. So that's what I'm held up on, I don't want to add the UV bulbs to my HVAC system until I have some way of measuring the impact on my indoor ozone levels.
