There are many people on this forum who use A Resmed CPAP with a non Resmed mask very successfully and I am one of them. I use both a Resmed mask and a Fisher and Paykel mask.
You need to quit thinking about this problem as a CPAP manufacturer problem and think about it as a system problem. Why did you replace your S9 autoset? Did your S9 have a Climateline heated hose? What position are you laying in when you get sprayed? Does it happen within 10 minutes of starting CPAP or later on? How much later on? On manual what makes 2 too low?
One thing that it would be helpful to know is the temperature of the room that you sleep in.
In general, the only way for a CPAP to "spray" water at you is for the water to build up in a low section of the hose until it blocks the hose. Then the pressure builds up behind the water dam and blasts the water out of the way. If this occurs reasonably close to the mask, you will get sprayed.
Having the machine lower than the mask is not a sufficient condition to ensure that any condensation that occurs in the hose drains back into the tank. You need to have at least the first 3 feet of hose continually rising with no dips where water might collect.
I would make a cozy for the short hose that comes with the mask and also for the plastic piece that the pillows fit into. If that was not sufficient, I would switch the long hose out to a non-heated hose making sure that I have at least 3 feet of good drainback and I might even forego a cozy on the long hose.
S9 does have a heated hose and works perfectly - no rainout ever. Hose goes up on headboard and back down as used with the S9. There is a hose cover on the hose and a tiny cover on the hose part of the mask. I have tried both the heated and non-heated hoses. The only thing I haven't tried yet is the duct tape recommended by the tech or a tiny cloth cover that you mention for the piece that holds the pillows. I guess I will try that before bronzing the machine.
The spraying would not start right away - maybe a couple of hours in. Room is 68 degrees. Everything is identical to the way the S9 was used - but because of the increased humidity purposefully designed into the Airsense 10, it's just too much for the Auto Climate to work with the Breeze mask properly - this is per the Tech Dept at ResMed. And using the manual settings is a guessing game - 2 feels too dry and 3 is moderate rainout. I don't know why - wish there was a 2.5 - but there again, it depends on the day's humidity so you have to guess what will work each day. That's why I wished the Climate control heated hose would work.
I purchased the Airsense 10 because my S9 is getting older and I liked the size and look of it and I stupidly thought it would work the same. Again, as per ResMed, in regards to humidity, they are Not the same. They said a person would have the most problems trying to use a Breeze mask with an Airsense !0 versus any other mask. Just the way it is, they said. So actually, it is a manufacturer's "problem" in regards to the mask I choose to use and the manufacturer admitted that very openly and honestly (with sadly, much laughter and giggling). I realize I would have better luck with a different mask, but cannot yet find one that will work for me. I will continue trying.
Frankly, I think that the laughter and giggling is very unprofessional and rather insulting and I do not blame you one bit for being incensed about that.
The fact that it has a humidity problem with one mask out of all the masks and at a few settings out of all the possibilities does not make the Airsense 10 at fault. If you had researched the Airsense 10 with the Climateline hose, you would have known that the auto mode for this machine is set to 85% RH instead of the 80% RH setting designed into the S9 Climateline in auto mode. Of course, even knowing that does not tell you how it will react with your mask. Resmed has stated that the 85% RH was a mistake, probably because many people are having more difficulty with rainout. Yes, I do know the difference between rainout and what you are experiencing and I can see the design features of the Breeze mask that cause that difference. One of the problems is the thermal conductivity of the plastic pillow holder.
I am surprised to hear that you have not tried turning the temperature up on your climateline hose. That would have been one of the first things that I would have tried and I would suggest that you give it a try along with your covering for the short hose and trying to find something to insulate the plastic pillow holder. Duct tape might not be a bad way to go especially if you put on several layers possibly with some old wool material between layers.
Why is the manual setting of 2 too low for you? Is it too drying?
