ResMed Quattro FX Full Face Mask Frame System-No Headgear (Large)
The Quattro FX's dual-wall Spring AirTM cushion provides soft, even pressure distribution around the nose and mouth absorbing even the slightest user movements. The cushion's supportive, inner layer stabilizes the cushion while the soft, outer membrane gently inflates to create a safe and secure seal against the skin. The Quattro FX's new Spring frame offers the same stability and angular adjustment as conventional full face masks but WITHOUT the annoying forehead support.
