Sierra, I have to disagree. I know what warm is vs room temperature. My model 10 and first model 11 were warm to the touch. If it is not warm to the touch it isn't working. Well, I shouldn't say that because I never , say, set the hose temperature to 81 degrees in a room that is 81 degrees.
Also, note that the two models use hoses that don't interchange. I'm not saying any model 10 has a heated hose problem. I'm saying a batch of early Model 11's did. My current machine , a model 11, even warmed up for about 2 minutes, then cooled back to room temperature after I did that "changing the settings and powering off and powering on" thing. My sore throat corresponds to the use of the Model 11's that don't heat up the hose. The last two. I'm hoping that the people that use the Airsense 11's that won't heat up the tube will post here and post when they received the machine. And all the ones that have Airsense 11's that DO heat up will post here, also. And post their serial numbers. Maybe I can get an idea which machines work, by serial number, so I can get one.

Funny coincidence. My Medical Device Company phone rep told me this week there still is no fitting for the oxygen for Airsense 11. People that need oxygen have to use the prior model. First week of June, 2022.

Sky, same here. I (thought I but probably didn't really) had trouble with my Airsense 10. They exchanged it for a model 11, the first in the office, they said. This was around January. That worked well in every way then totally died within two weeks. So I got a second model 11. That one didn't die but the hose wouldn't heat up. They sent me a second hose. That wouldn't heat up either. They now gave me my third model 11 and we tested it in the office. The hose (well, both) would not heat up. I said, "Let's keep trying them until we find one that works." But they wouldn't do it. The guy hinted that there is no point in trying more since every one he had in the shop was from the same batch. So I went home with the third one. At one point I changed the temperature settings from 88 to auto to 86, and unplugged the machine then plugged it in. It now heated up, fine, but only for about 2 minutes, then the hose shut down. The water still heats up. It is near empty after about 3. or 4 hours. I don't know where it goes, but it doesn't feel humid going into my throat.

My throat has been hurting since I got the second Model 11. I called around. Different ResMed people , and different people at the medical device company. I get the feeling they know the machines are defective. Especially the ResMed people. But they are recorded when they talk to customers so have to be careful what they say on the phone. My only hope is to wait long enough to get an exchange where they have ones that don't have the heated tube defect. I understand they can alter software remotely, so maybe they are hoping to patch the operating system without anyone but us knowing they shipped thousands of partly defective ones. I mean, like stockholders knowing.

Imaging Resmed gloating about Phillips problems with their recalls then finding out your newest product has bugs. So , no surprise that they'd want to keep it secret.

By the way, none of my model 11s gave me the solid sleep my model 10 did. Well, did a very few times. But that is not what the data says on the readout.

Fun fact. I was just told ResMed does not yet make a tube for the Model 11 with the T fitting for supplemental oxygen.
