Product review (5 stars): Most Amazing Air Purifier Ever
This machine is amazing.  For the few minutes when it's being cleaned, you can totally tell the difference in the air quality.  The machine runs quietly and I forget that I have it.  It is easily cleaned and the replacement parts are inexpensive considering that I only bought them as back up and have yet to use them and I've had the air purifier for over a year.  Loved it so much we purchased one for our daughter's home.
