Need Help with Mask Condensation (no hose rainout)

.
Hi all, I have been on CPAP therapy since 2007. Last year, I started getting water droplets in my mask along with dampness where I have to wipe the mask out a few times a night. The heated hose is always completely dry. When it started, I had not changed anything...masks, room temp, CPAP settings, nothing. So it baffles me what started it. I am still having the problem every single night. I have tried changing heated hose temp and humidity settings to no avail. I recently changed to the AirFit F40 and I have the same problem with this one. If I drop down the humidity too much, I get a horrible dry mouth. Room temp is normally around 69-70. Any help would be greatly appreciated.

Yikes! I've been 9 characters since then!

I had a similar problem with the water dispenser in my side-by-side refrigerator-- everything froze because one micro-atmosphere invaded the other.

Anyway, take the cushion


and cover it with thick flannel, tiny-bubble bubblewrap or anything that will provide insulation. Cut out holes and slots for hose and attachment protrusions. Use double-sided tape or some adhesive to hold in place if necessary.

'Member the old hose-cozies? Same idea.

I was trying to think of a way to cover it, but didn't want to use glue...have no idea why I didn't think of double-sided tape! Bubblewrap sounds interesting, but wonder if it would start popping during the night since I sleep on my side...haha! I will be trying your suggesting tonight...THANK YOU!

Yep, I remember the old hose cozies. I also remember ordering my first heated hose from a company not in the US where I am because no one here sold them yet.
