Cushions for the Quattro FX Full Face CPAP Mask

Dual-wall Design

The replacement Full Face Cushion for the Mirage Quattro FX come as a single cushion in your desired size: small, medium, or large. All three sizes fit on the ResMed Mirage Quattro FX, but aren't a match for the original ResMed Mirage Quattro.

The dual-walls consists of an inner, supportive layer that stabilizes the cushion and a softer, outer membrane that reduces the likelihood of leaks and pressure sores. As air flows through the cushion, the outer membrane rolls and inflates around the nose rather than stretching over it.
