Clears the air
I have had this product only a short time, but it's time enough to learn that It does an excellent job of clearing the air. The noise, as previously reported, is annoying, but I chose to buy it anyway. I would almost go as far as to say that it rivals the noise of my oxygen concentrator which is on 24/7. Because it plugs into an outlet I easily moved it to an area where I don't feel the two items are competing with each other. If Germ Guardian could duplicate the simplicity of this item without the noise, I would certainly buy it. In fact, I may buy another one of these.
