I just bought a Venta Sonic humidifier( VS-205) and it is the BEST one I have ever used. It is quiet, can be warm or cool and you can set a level of humidity and it will shut off when it reaches it. Honestly it is great! It is German, and you can buy them at various places (Bed Bath & Beyond I think, Amazon and Tuesday Morning -where I got mine). They are small and can do one or two rooms at most, but are also not that expensive, so you could buy a couple to do the whole house. That's what I am going to do now that I have tested it.
