The Mirage Liberty™ is a hybrid style CPAP mask 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 mask. With fewer mask parts than other full face masks, 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 mask that seals individually at the mouth and nose. With less skin contact and an open field of vision, this unobtrusive mask feels light on the face. These replacements mouth nasal pillows are available in small, medium, and large sizes.
