It's been a while since my last login. Hope all is well and that you all are winning the battle.
Here's a simple thing I did with my P10 headgear, after the straps became really loose, and soaking in hot water stopped doing the trick. As a result, my P10 pillows were not pressed tight against nostrils, and I started experiencing lots of air leaks throughout the night.
One solution is obviously buying a new mask, or at least a new headgear, the other one would be those strap clips. Frankly, I wasn't very happy with any of these options, pricing wise, so I tried something else, and it seems to be working just fine, at least for now.
I simply tied a knot at the end of one of the straps, shortening its length. Tried doing it on both at the same time, but then it was too short and way too tight. Here's a picture of what it looks like:
Much better fit, and leak rate is dramatically reduced.
