It works.
Have been using it for a few days now and didn't really notice the difference until I left for a few hours and came back inside. Definitely notice a change in smell, or lack thereof, in the air. We have a 1700 square foot house and I've positioned it near the return air duct to help the air get around the rest of the house. My wife burned some toast today and the smell didn't last as long as it usually does.<br /><br />If you run the fan at full speed there is a fairly significant noise with that, but you can adjust the speed, and the noise, down to your liking.<br /><br />Undecided on the ozone feature, but you can also dial it up or down or turn it off completely. I dialed it up when the toast burned, but there are cautions in the manual about exposing yourself to too much.
