I want to save you some time and recommend this one. http://www.amazon.com/Crane-Ultraso...=8-2&keywords=ultrasonic+cool+mist+humidifier I tried and failed 3 times with 3 different humidifiers and this seems to be the winner. A member recommended it to me because he hadn't had any problems with it. There is no filter and no mold issues. I have been using it for about a month now and I haven't seen any problems yet. The member who recommended it to me has had it for a year I think. Good luck!
