just a bit safer during virus season. .
We have one of those UV lights as well. It was already installed when we moved in. I have since done a LOT of reading about them and the general consensus (other than from the dealers that sell them) is they do little good. They DO NOT need cleaning (no idea why they would tell you that) but they do need to be REPLACED every 1 to 1 1/2 years because even if they still "glow" the UV output is greatly reduced. Also, if they are usually set to only go on when the system is running (which is not a lot) they do even less good. Since it was already there I have replaced the bulb ($60-$100 depending on where) twice in 5 years myself (they NEVER are dirty) but am wondering if it is of any real value any longer. I did rewire it to be ON all the time as long as I had it.
