Love It!!
I purchased 3 of these about 4 months ago.  I am a smoker and smoke in the house. With these little beauties running there is little to no odor, family and friends come over and would never suspect that I smoke in the house.  They also help eliminate any cooking odors in record time.  I have one in my living room, 1 in my dining area and 1 in my bedroom - they run 24/7 with no noticeable increase in my electric bill.  If you are sensitive to odors you need to get this.
