I bought both, the Pure Air -Ultrasound and the humidifier Wick-610E. The Pure Air has its advantages: nice, compact, easy-to-use water tank, buzzing about as loud as a fan, he does not have so often be cleaned. Disadvantage he clouded the water and needs only in my 25 square meter room almost 3 hours to about 45 to 55 percent moisture come. The humidifier Wick-610E has the advantage that it barely needs more than an hour for the same performance. I then make him an hour before bedtime. He is a little louder, he gurgles like a pressure cooker on a hot plate and actually has the same functionality. Disadvantages: the water tank is cumbersome and clunky at the sink and the device is after 2 weeks use of one hour a day so calcified that you have to take it apart again and the Teflon ground again soak with vinegar and must be cleaned. I believe in the guidance is: weekly clean. I mean that children can not scald, the container is only Luke warm. Only the flow of steam coming up out is very hot but just right at the opening. I tried it, it shrugs his hand then quickly away again because it is a too hot.
