The ResMed AirFit™ F30 replacement cushion is made of a silicone material that provides you a seal when attached to your F30 full face CPAP mask. Facial oil build up on the silicone will break down the consistency of the cushion over time and lead to mask leak. When this occurs it is time to replace your AirFit™ F30 seal. The “Fit” series and “Touch” series are the newest family of sleep apnea therapy products from ResMed. The full face style implements a design that covers the nose and mouth allowing the user to breathe through both.
