This is the Replacement cushion for the Philips Respironics Amara full face CPAP mask. Choose from four sizes according to whichever size cushion you currently use - petite, small, medium and large. Note that all sizes of cushions fit on the same mask frame. Built on an entirely new, lightweight platform, Amara is designed to be extraordinarily appealing to patients and extremely simple for you to fit. A unique modular design uses one frame to which a petite, small, medium, or large-size cushion simply attaches with one click-no more matching frame sizes with cushion sizes.
