Troubleshooting - ResMed AirFit N20 User Manual

You do not need to clean the AirTouch N20 cushion every day.
It is recommended to replace your cushion every month. If any
visible deterioration of the cushion is apparent, the cushion
should be discarded and replaced. If required, wipe the
outside of the foam cushion with CPAP wipes or similar
alcohol-free wipes and allow to dry. Do not store or place the
cushion in direct sunlight.

Solution
Remove and refit your mask according to the
fitting instructions. Ensure that you position the
cushion correctly over your nose before pulling
the headgear over your head. Do not slide the
mask down your face during fitting as this may
lead to folding or curling of the cushion.
Reposition the mask on your face. If leak
continues, turn off device, resettle your cushion
and then turn device back on.
Cushion performance may deteriorate as the
foam nears the end of its lifespan. Adjust your
headgear and if the problem persists, replace
the cushion.
Ensure that the headgear straps are not
overtightened or too loose. You may find that
this mask does not need to be tightened as
much as other nasal masks.
Check that the headgear is not twisted.
Talk to your clinician to have your face size
checked against the fitting template. Note that
sizing across different masks is not always the
same.
Disassemble the mask, then reassemble
according to the instructions.
