Troubleshooting (AirFit F20)
Problem/possible cause
Mask is uncomfortable.
Headgear straps are too tight.
Mask could be the wrong size.
Mask is too noisy.
Elbow incorrectly installed or incorrect
assembly of the mask system.
Vent is dirty.
Mask leaks around the face.
Cushion membrane is creased. Mask is
incorrectly positioned or adjusted.
Mask could be the wrong size.
Solution
The cushion membrane is designed to inflate
against your face to provide a comfortable
seal with low headgear tension. Adjust straps
evenly. Ensure that the headgear straps are
not too tight and that the cushion is not
creased.
Talk to your clinician to have your face size
checked against F20 fitting template. Note
that sizing across different masks is not
always the same.
Remove the elbow from your mask, then
reassemble according to the instructions.
Check that the mask is correctly assembled
according to the instructions.
Use a soft bristle brush to clean the vent.
Refit your mask according to the instructions.
Ensure that you position the cushion correctly
on your face before pulling headgear over
your head. Do not slide the mask down your
face during fitting as this may lead to
creasing of the cushion.
Talk to your clinician to have your face size
checked against fitting template. Note that
sizing across different masks is not always
the same.
