Thanks all. I am going to the respiratory therapist Monday for a Respironics System One on Monday
I have had one of those since 2010 and mostly use it as a travel unit. I do have one big issue with it. I have found that when using the unit without the humidifier attached there is a lot of air movement noise in the tubing and mask. So much so it is hard to fall asleep. When I put the humidifier unit in line the noise dissipates. I don't even use water in it or power the humidifier on. Seems like the dry humidifier bowl dampens the air movement noise substanially.
One other issue is the noise level of the unit varies up and down with inhalation and exhalation even with the cflex option turned off.
I have used several models of respironics units over many years because most of them have native 12v capability but this unit is by far my least favorite.
I believe that you will find that the smaller and lighter the unit the more the motor noise will vary with inhalation and exhalation. I have a really old resmed s6 lightweight that is fairly heavy with no 12v and it has been my best unit for home. Motor noise is constant and very low. I actually got this unit at a thrift store for $10 and it just will not die.
