I honestly don't know how I lived without this air purifier. I can already feel a big difference in the air quality in our home. It's a nice looking unit and will fit in with all types of decor. It's not too large but gets the job done. I love that there are lights to indicate the quality of the air...blue, yellow and red.  My husband has occasional allergies and they seem to have lessened after using it. It is not loud at all but you will hear if it switches to yellow or red. Plus I love the noise that it makes when you turn it on and off!
