Noticeable reduction of odors!
I just installed it and I immediately noticed a reduction of odors in the vents! I bought it to reduce the crawlspace smell in my AC coil/furnace. I can still slightly smell it, but hopefully it goes away completely after it's be on for a couple days. Only a very small electronics/ozone smell, it's not bothersome at all. I think it makes it smell fresher in the house.<br /><br />The mounting template is not correct. Be prepared to modify it. That's the only reason it's not 5 stars.<br /><br />I installed just above the AC coil and used my own self tapping metal screws for the installation. I like the longer 16 inch bulbs at 36w each, and they fit perfectly in my supply trunk. Make sure to measure your ductwork before purchasing.
