"Uv lights do not create any byproducts.  You may be thinking about ozone. Ozone has some good uses in UNOCCUPIED buildings,  Ozone will damage many things so regular use is not a good thing  but if you have smoke or other odors you…"

"Richard and Robert, Good posts. You mention concern with chemical pollutants that aren't captured with particulate filters. My understanding is that UV lights can also create ions and charge particles in the airstream. How does ionization…"

UV lights on filters

I recently saw UV bulb installations in 2 HVAC systems in a home. Each system had the Lennox Healthy Climate filter box that has 2 UV-A bulbs inside; the label said 150 watts which I'm assuming is the total for 2 bulbs. These bulbs are on 24/7/365. I calculated that at 150 watts per filter box x 2 boxes they are consuming almost 2600 kWh per year, costing the customer about $30 per month. My recollection is that trying to sanitize the airstream is basically ineffective and that the only place…See More
