Condensation in Mask

[zzz1]

For the past two nights I have been getting condensation in the mask with the ClimateLine Tubing.  The tube is clear and the condensation seems to be in the mask.  On both nights the room temp was 66 - 67.

Night 1: Straight 77 / 4.

Night 2: I started out auto climate control and auto tube temp.  It felt slightly warm so I kept auto climate on and changed the tube temp to 77.  I'm guessing with auto climate on the machine sets the humidity level for the tube temp to avoid condensation.  I've used auto climate on and tube temp 77 for most of the past week with no issues with the same room temps.

Any idea why I would get condensation using the auto setting?

Soooo it turns out that in the middle of the night I thought I changed the settings to 77 / auto climate control, but apparently did not and did 77/4 again.  Please disregard.

I can get condensation in the mask when the room is cooler than my usual 22C (72F), Our nose and lungs add a lot of moisture to the air we exhale, so if the mask is cool, that moisture will condense on it.

zzz1, what mask model are your using? A full face mask presents a large surface area to the ambient air, and if humid air hits that cooler surface, it can condense. The solution is to reduce humidity, increase the temperature, or insulate the mask surface. Take a look at the Pad A Cheek full face mask liner, or the CPAP Comfort Cover as examples of insulation. Also, you might turn the heated hose temperature higher (80 F) to provide a slightly higher temperature with the same humidity into the mask. The other way to avoid this is keep the room warmer.

I’m using the F20. I thought I had left it set in Auto Climate but when I checked it was in manual mode. The tube itself was clear so it probably was the combination of the humid air and warm breath hitting the cooler mask surface.

I noticed that the condensation is only in between the part of the mask where the headgear attaches and the the part where the cushion attaches to it, but not beyond that area.  Is that pretty much normal for condensation?  The tube remains clear.

I'm only asking again because I used AutoClimate On and I didn't expect to see any condensation with the machine handling everything.  I did change the temp to 77, but kept AutoClimate On and expect the machine compensates.  Room temp was 66.

I dropped the mask a couple of times and it popped apart.  I put a new cushion on since, but wonder if the headgear part of the mask where the cushion attaches became slightly off somehow?
