re: Anyone Installed a UV bulb inside your air ducts?

Plants need uv light in order to grow

I get that but what I meant was the specific parameters you mentioned for medical use are now being dialed in to also kill mold in the grow facilities because of Gov regulations. They are going above just using generic UV lights to grow the plants and stealing a page from the medical industry to fight mold and pass inspections.

Yeah man. I have been the sucker on these vent and duct cleaning deals before. This is just the next version. If you and your family aren't chronically sick, just change your filter at regular intervals.

And that smell always happens when switching from hot to cold. It smells musty. That is normal. You don't need a light bulb to fix that.

I've used UV rays for water treatment and there's a lot of maintenance involved. It is expensive. Bulbs have to be cleaned often. They have to be replaced annually. I think a whole-home dehumidifier would be more effective against mold.

Air filters absolutely work.

I mean the Sharper Image type filters. Not an A/C filter. All you have to do is look at one when you change it to see it works. Come on now.

I should have clarified. I mean the "ionizers" and other type products that do not move enough air to catch anything.

I did not mean your A/C filter.

UV lights are used in tissue and cell culture laboratories around the world for this exact same reason. UV light at very specific parameters is an excellent method of sterilization. On the other hand, the lights need to be changed very frequently because as soon as the output drops out of those very specific parameters then it is worthless. In labs, they are supposed to be inspected every 3 months and are usually not sterilizing very well by 6 months.

I was about to post something similar. It can be very effective in operating rooms and labs. My father used to be involved in the business. It will certainly kill mold and other nasty stuff, but I doubt that most residential products would even come close to working.

My dad brought home one U/V light years ago when they first started showing up in the industry. We plugged it in and held it over our driveway for a few seconds and waved over a small area. After a few days, that section of driveway looked like it had been pressure washed. So, that's my anecdotal evidence.
