This is the replacement elbow for the Mirage Quattro full-face masks.
Important Tips
Quattro mask frames, cushion clips and cushions are NOT interchangeable
To find the size of the cushion, flip the mask so you can see the underside of the cushion. There should be a large, clear embossed letter on the silicone flap that specifies the size.
The cushion, mask frame, and cushion clip are required to be the same size for the mask to work efficiently.
The Mirage Quattro does not have magnetic clips so it is safe to use for anyone with a pacemaker or defibrillator.
