These Nasal Pillows Sleeves are designed for use with all Mirage Swift (Original) CPAP/BiLevel Masks.
Sizing Information: The Mirage Swift (Original) uses a single frame size so any pillow sleeve will fit on Mirage Swift (Original) any mask. The sleeves are interchangeable, so if you are currently using a small pillow sleeve and feel a medium might work better for you, you can just purchase a new sleeve to change the size of your mask. For best performance replace every 3-6 months on average.
Usage Information: These Pillow Sleeves have vent holes on the front. They WILL NOT work with the Mirage Swift II CPAP/BiLevel Mask. Those pillow sleeves are available elsewhere on this site.
