This Silicone Full Face Cushion, from Respironics, is supplied with all Amara Silicone Full Face CPAP/BiPAP Masks; and it can be used as an alternate cushion for Amara Gel Full Face Masks. The lightweight, clear silicone cushion offers a more traditional fit that uses airflow from your CPAP or BiPAP machine to seal the cushion gently against the face without pinching or pressure points.
