Recently I purchased Silent night mask liners. Liners work to good, complete seal. Prior to liner, mask was sliding all over my face, from oil/sweat, strap adjustment, Resmed Airtouch F20 mask would slightly leak for various reasons.
6 out of 12 nights 0 leaks other 6 nights, very minimal leaks 1-5 L/Min, I did have one night 18L/Min
My AHi has not been above .3
During 12 nights, I did not wake up one time, but I developed severe aerophagia, I could hadly eat or drink anything

Super happy about mask liner, but aerophagia is the worst.......
