These Nasal Pillows Sleeves are designed for use with all Mirage Swift II CPAP/BiLevel Masks. For best performance replace every 3-6 months on average.
Sizing Information: Because the Mirage Swift II uses a single frame size all pillow sleeve sizes are interchangeable; therefore if you are currently using a Small pillow sleeve and feel that a Medium might work better for you, you can just purchase a new sleeve in order to change the size of your mask.
Usage Information: These Pillow Sleeves have a solid front with an embossed ResMed logo. They WILL NOT work with the Mirage Swift (Original) CPAP Mask. Pillows Sleeves for the Mirage Swift (Original) are available elsewhere on this site.
