Negative Positive
Title: It helps clean the air.
Review: This unit makes a noticable difference in the air quality, even though I am using it in a large room. It has two settings, low and high. Using the high setting, it is a little to noisey. On the low setting it is quiet enough to use in a living area where a person might watch tv or listen to music. The low setting does work, even for cleaning tobacco smoke smell from my house.IMO the thing is not attractive, and the top is not flat so you can't use it as a table.I gave it four stars because it does make a noticable difference in the air quality.
