Product review (5 stars): Does the job
I like the size of this humidifier/vaporizor, but it is a little noisier than I expected.  I could not find the filters instore anywhere, which was very annoying but I think I saw them at WalMart recently.  We run the vaporizor almost 24 hrs a day since our baby girl was born 2.5 yrs ago and I have used 4 filters.  It's good for white noise too.  Just remember to run it dry each time to make the filter last longer and prevent mildew from growing in the container.
