Problem with Airsense 11.

Post by Cronig » Tue Jun 10, 2025 11:57 am

I have been a C-Pap user for approximately 10 years. For most of those years I used the Resmed Airsense 10.No problems at all. I’ve had a newer Resmed Airsense 11 AutoSet for about 16 months now. It has a problem but the company denies this. It’s been sent back twice and they say nothing is wrong. The local provider of course backs the company. I’m checking to see if anyone else has had this problem. If the water reservoir becomes empty, which is rarely, a bad smell comes through the machine into my mask. It’s bad enough to wake me up, usually right a way. . if I don’t wake up quick enough I can taste it and has even has gotten into my throat. It has been sent back twice as I mentioned and they think I’m crazy. Has anyone else ever had this problem? I bought a mini and don’t know if I ever want to go back to my Airsense 11.

Does everything work normally if you don't run out of water?
Is there a specific issue that makes you run out of water?

Nothing is wrong, you are describing a behavior that many have complained about for the Air 11, Air10, S9 and even non-ResMed devices.

Heating plastic smells. Without any water in the tank, you are going to get that smell.

When your machine is dried out...do you observe any white calcification on the plate in the reservoir?

Before I dialed in my temp and humidity settings,... I used to frequently empty the reservoir in a single night and the plate used to develop a slight crust ( which I cleaned)
This used to give me a taste and smell sensation. Not plastic...more like a burnt dry powder.
