Quiet and efficient

Have tried several brands and models, this one is absolutely the most quiet model I have come across (don't go for Vick's brand for the bedroom as they are the nosiest). It quickly puts out a lot of nice warm humidity. I have used it in my 2 1/2 year old daughter's bedroom and also in the bedroom where the rest of us sleep (my 2 month old son, my husband, and me). This really works!
I've tried other brands and either have not gotten enough output, had problems refilling the water, messy filters to change, or the humidifier has been too noisy for a bedroom. If you are looking for a humidifier for a small/medium bedroom this is the one I would recommend.
