1byone Ultrasonic Cool Mist Humidifier and Aroma Diffuser http://www.amazon.com/1byone-Ultrasonic-Humidifier-Diffuser-Automatic/dp/B018RUZGGW A good way to relax at night and fall asleep feeling great. I suffer from chronic sinus congestion and most than not I get a dry uncomfortable feeling in my nose, and this could lead to a headache. The humidifier helps a lot, the air feels much cleaner and after adding some essential oils is really awesome. Last through the night and the smell of the oil is so subtle and relaxing. There is no noise and it I very easy to operate, it even shuts down when there is no more water in the tank. Love the color led lights.
