If you have the humidifier attachment installed, the noise completely goes away and it is silent. Without the Humidifer in place, it is so noisy that it is difficult to sleep. Something changes with the airflow, and they obviously designed it for primarily to be used WITH the humidifier. I was hoping to use it without the humidifier most of the time, as it is compact and great for travel, but sadly, it is so noisy that won't be possible.
I have not used the humidifier and face same sound problem.
Is it the humidifier / water tank act as a muffler to reduce the sound of air flow from the main unit to the tube??
