The Quietcool humidifier I just purchased is just as you advertised, and more.  Quiet and does a great job in putting humidity into the air of our dry living room area.  Very happy with it.


 Excellent product.  Already had 2 of these and loved them.  Consequently, when it was time to buy another this is the one I chose.

Super Unit

A great machine. Large water capaciity. Powerfull fan, yet very quiet on the low setting. And that is where I find I have it set 90% of the time. Cool led's show your fan and humidity level selections. Am very pleased with this unit
