So, um, there might have been nothing wrong with my machine. I might have had my pressure too high. Way, way too high. Like, at min 16-17 cmH2O. For the life of me, I can't remember WHY I did that. I seem to remember having trouble breathing in enough air at lower pressures, especially when my sinus...

Well I just pulled the trigger and ordered a new CPAP because I noticed CPAP.com was having a sale, so I saved nearly $200 on it. It's well before I was planning on replacing it, but... Oh well, at least I'll have a working spare.

Yes, so do I, which is why I made this thread

For the first 2 years of use, my CPAP used 25%-50% of the tub. As of late last year, It now uses over 100% - as in, I'll often wake up early in the morning to a bone dry tank. I've taken to filling it up exactly to the line, and then filling it up a bit more around 3 AM when I inevitably wake up due...

Got my replacement mask yesterday! It seems like less air is now leaking out of the elbow, so I was hoping this would solve the issue, and used it for the first time last night. ... No dice on the humidifier tank. It ran all the way to nearly empty from full again, and my mouth was dry again. That m...

Ok, so, I pulled out my old broken cushion to see if there was any difference, and there is - the old mask has a tighter grip on the frame when you try to separate them. I don't know if that's the issue, and unfortunately I won't find out until my new mask comes later this week (as I can't use that ...

Good to know - thanks! I'll explore that as an option after trying a new mask. If anyone else has any insight, let me know.

You're right, I should try replacing the mask. It's coming up on when I was planning on getting a new one anyway. I've ordered an entirely new one with several spare cushions. I'll see how that goes, and probably get a new hose too, although I'll try out some of my old hoses first (they have some ho...

Yep, that was the first thing I tried, a few months ago. It didn't change anything.

Thanks for the reply - I'm using an Airfit F20 (with a liner from padacheek). I can't detect any leaks in the mask seal or the hose, and I've double and triple checked those because I'm usually very, very sensitive to leaks. If there's any air blowing in my eye i have to adjust and re-adjust until i...

So, I've had my Airsense 10 for just over 3 years now. And it's worked pretty much fine up until the last few months, where it's started burning through water at a much faster rate than normal. When I first got the machine, it would use a small portion of the water in the chamber - now I fill it to ...
