Sizing the mask
Your physician or sleep therapist can assist you in selecting the right size
cushion.
If the mask frame falls back over your head or sits too close to your ears,
try a smaller frame size. If the mask falls forward on your head or sits too
close to your eyes, try a bigger frame size.
Disassembling your mask for cleaning
If your mask is connected to a device, disconnect the device air tubing
from the mask elbow.
1. Undo the fastening tabs on the upper headgear straps and pull from
the frame. Keep the mask clips attached to the lower headgear straps.
2. Squeeze the side buttons on the elbow and detach from the frame.
3. Grip the frame connector and lift to unclip from the cushion. Repeat
on the other side.
