AirFit F20 homemade Mask Liner
First off, I love the F20 FFM, however I found that after a couple of months, it just starts to leak and wakes me up during the night when you get that brrpppp sound from the side of your face.
I have tried suggestions from the mask primer, I wash and use cpap wipes, I just have a hard time getting it to seal properly over my cheek area. Funny thing is, if I open my mouth it will stop the leak, however mouth breathing seems counter intuitive.
Anyways, I searched online and came across mask liners but they were very expensive for what they are. So, I decided to try to make my own version last night and see how that would work.
It actually worked much better that I thought it would and I did not have to adjust for that brrppp sound leak at all. First in a while. Strap tension was even just a bit loser than without the liner. I did have a tiny bit of leak around the eyes initially but then moved the cover back more at the top so that there was more silicon available on the nose bridge.
Basically, I took a never used pair of dress socks and cut them into 3 -1/4" tubes and just placed them over the mask as shown in photo.
There was no itching, scratching or annoyance, nothing It was even out of my visual as well. I did notice that the edge of the material did leave a thin red line where it contacted my face, the same way the straps do.
simple easy mode that might help with some leaking for some people. I figure it must just put enough pressure on the outside silicon walls to keep them from flapping so to speak.
I think I may play around with the sock material. Maybe try a felt or flannel or even some type of nylon or spandex material to see which is better. Perhaps even fold ends over and sew them to make a nicer edge that will not be pron to coming apart once I wash these.
For the price of a pair of socks, it is worth the try compared to what they cost on amazon or elsewhere.

I actually think I woke less during the night. AHI back down below 2, (1.8) and I raised my EPAP from 13.4 to 14 just to see how the extra pressure felt. Felt great.
