Need a good nights sleep?
I got this for my wife, and she didn't plug it in for quite a few weeks as she was very skeptical  of it.  Finally a few months ago, plugged it in, and lo and behold, a perfect nights sleep for a change.  Now its plugged in all the time.  As always the Amazon reviews prompted me to get this and it is the perfect companion to the Germ Guardian Hepa air filter.
