Flappy nose piece

[DariaVader]

Night before last, I woke up to a loudly flapping (vibrating) nose piece on my P10. I got up and swapped it out, but the next one did the same as soon as the machine came on. Almost like as if there were a lot of water in the tube (but there wasnt). So then I swapped out the hose and the mask frame, and the previously flapping nose piece behaved itself and I slept the rest of the night....

Haven't tried the misbehaving hose or mask again yet... but has anyone had this happen?

I have experienced it from time to time. Almost like a fluttering or popping in the pillow itself. It has usually cleared up on its own, but it is just weird sounding. I doubt anyone hears it but me.
