Product review (1 stars): Too Noisy
This is very good looking, well functioning unit. The only problem with it is the disturbing CONSTANT swishing noise it makes, sort of like a respirator.  And it's fairly loud.  It can be heard thru a closed door!  I've seen similar complaints from several other sites, so it's not just this individual unit. So buyer beware.  Make sure it will be in area where you do not mind the perpetual and rather disturbing noise.
