It was enough to make my nose hurt. The humidifier control is also on a fairly low setting. It is below the halfway point.
Perhaps the same thing happened to me last night. The water tub was full but I started smelling a burned-like smell. It also seemed like the pressure and airflow were perhaps less than normal.
I turned the machine off and moved things around, and the smoldering smell cleared up completely.
I think something had been obstructing the air intake (where the air filter is), and the lack of inlet airflow caused the machine to heat up.
If the outlet airflow is restricted (say we remove the mask from the hose and we use our palm to completely block the hose outlet) the machine is not stressed at all, because the outlet pressure is at the target output pressure and the machine has less work to do to maintain the pressure (it does not have to produce as much airflow). But if its inlet is blocked and it is unable to achieve the target output pressure, it may work as hard as it can but still be unable to reach the target output pressure. I think this was what was causing my machine to overheat.
Very important to not allow anything to get too close to the air inlet and obstruct it.
In your case, perhaps when you removed the humidifier you unknowingly also moved whatever may have been blocking the air inlet.
Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.
I had that happen to me once. I had just opened a new jug of distilled water and filled the tank with it. I couldn't get to sleep because of the burning sensation and smothered feeling. I dumped the tank and filled it again from the same jug. The same feeling again. So I dumped it and filled the tank from a new jug from a different store and everything was fine. The first jug went down the drain and needless to say, I don't buy my water from that store any more even though I had never had a problem with water from there before.
The sensation I got wasn't a bad smell...it was a burning sensation and a feeling like I wasn't getting enough oxygen.
You might be onto something ! I sanitize my equipment on Sunday nights and that was the night that i got fumes. Two thing were different when I sanitized that night . One. I switched to Control 3 sanitizer . Two. I picked up a gal of Distilled water from the same store but it was from a different bottler. I use distilled water for a final rinse and flushing the hose and humidifier , then filled the tank for the night . I had also installed a new water distiller that night but had to wait for it to produce enough water to use . No more buying Water..
I went to bed about 11:30 and woke back up around 4:00 nose burning from fumes , Thinking the fumes were from using the new cleaner I changed the humidifier tank and hose and refilled the new tank from the still and went back to bed . haven't had a problem since . Now you have me wondering if it was the water ? This being Sunday I will retry the control 3 again but using my home brew distilled water to flush and refill tonight .
