Product review (1 stars): Avoid
I bought this humidifier in late 2013 to add humidity to my guitar room.  (This is an average sized remodeled bedroom with new carpet, insulation, sheetrock, and double pane windows.)  It ran constantly and could rarely get the humidity above 35-40%.  Almost immediately, the electric fan motor began to run roughly and make a rattling noise.  Through no small miracle, one day I happened to be in the room when the fan motor just stopped and began to stink like hot electronics.  I unplugged it and called the company.  I will admit that they were very helpful and could not get me a replacement fast enough.  However, the new humidifier is no more effective and has started making the same rattling noise.  I'm afraid this one will get hot and stop as well.  I've monitored and maintained the unit as instructed and replaced the filters as directed.  If I could get my money back I would take it in an instant.
