This is the replacement cushion for ResMed AirFit™ F30 Full Face Mask. The UltraCompact cushion
is designed to seal securely at the bottom of the nose to prevent nasal bridge discomfort and red marks. Small and Medium size cushions are available and either size cushion will fit on the F30 frame, making them interchangeable. There is no Large size in the F30, as the medium size cushion with the adjustable top headgear strap will fit most patients that require a large size.
