Philips Respironics brand large silicone cushion for the Amara full face CPAP mask. This cushion is easily changed and snaps into the mask frame. These cushions are also available in a gel version and are interchangeable so if you currently use a large gel cushion you can use the large silicone cushion on the same mask frame. In general, we recommend replacing these cushions every six months, or when they develop air leaks. Pk/1
