Hi friends, desired to share last year I switched over to Resmed Airtouch F20 from Qauttro, many issues at first, headgear, leaks, etc... Once I figured out how mask fits on my face properly, I ordered Silent night mask liner and neck padding.
Past several months 0 leaks !!!!!!!!!!!! No Ahi over 1 !! I download data from Resmed Myair past 3 months, don't know how to attach image. I'm still in disbelief.
My little secret, suppose to change liners every week, I change once a month

The trick is, wash or wipe face down, before using mask liner.
Sleep wonderful friends............
