I love this humidifier. I have bought several over the years at different price points. The Ultrasonic cool mist humidifier is affordable and efficient for the bedroom. One of the selling points for me was the ability to wash it inside. Living in NYC, decalcifying is an ongoing task, and this feature makes it so much easier to clean. Also, the filter is affordable. I will get another one to replace the boneco slowly dying in the other room.
