Thanks... I dried out the hose by just detaching fromthe maske and running the machine. I will see if my provider will authorize a heated hose or I will turn it off. Many thanks

Thanks for the quick reply. I do not have heat tubing. I will check to see if there is condensation and if water has overflowed through movement. The chamber is tightly set into the machine. I wonder if I put no water in the chamber, the problem would cease. Anyone have this experience? Is it a problem, other than having dry air, not to use the humidifier?

I have just started using AirSense 11 machine and have tried several masks with assistance from my Sleep Lab. I finally thought the N30i pillow would be most comfortable. However, most nights, my sleep is interrupted by loud popping sounds, seeming to come at the attachment point on top of the head. I have checked every fitting and everything is secure. I have lookied on the forum for this topic, but can't find anything. Any one know a solution for this?
