Thanks Pugsy. No it does not wake me and it is never over 30-35. I am going to quit worrying about it. I will change my hose and see if that helps. Have a good day.

Pugsy. I have a question for you relating to this. I noticed you said a brand new mask can leak. I have a terrible time with mask leaks. I have tried many different ones. I am currently using the F40 with pretty good luck. I recently changed out entire mask and it is leaking every night up around 30...
