The Mirage Liberty™ is a hybrid style CPAP Interface that uses a mouth cushion seal in conjunction with nasal pillow inserts. This is a great option for CPAP users that have a narrow nasal bridge that cannot be seal with a standard full face CPAP. With fewer parts than other full face interface, Mirage Liberty is easy to handle, assemble and disassemble for cleaning. It is easy to put on and take off. Mirage Liberty is a full face interface that seals individually at the mouth and nose. With less skin contact and an open field of vision, this unobtrusive interface feels light on the face. These replacements mouth cushions are available in small and larges sizes.
