If the liner moves or bunches, try the following:

- Confirm you are using the correct liner for your mask and cushion size
- Ensure the liner lies flat inside the cushion before putting the mask on
- Avoid overtightening headgear straps

Small adjustments to mask placement can often resolve this issue.
