SIZING: The Mirage Swift II uses a single frame for all sizes, so all pillow sleeve sizes are interchangeable. If you are currently using a Small pillow sleeve and feel that a Medium might work better for you then you can just purchase a new sleeve in order to change the size of your mask.
USAGE: For best performance replace every 3-6 months.
The pillow fits well, but it does not have the the small holes in the piece that allows air to escape during use. I will have to make the holes with a needle or pin. Written by Verified Shopper, 2018-09-24
.It works for me
Pretty sure I selected Medium on the website but received Large. It seems to work fine though. So maybe it was fortuitous. Written by Verified Shopper, 2018-05-31

.Much more convenient to purchase
These products are the same products supplied by Pulmonary Companies, but less expensive to purchase, as well as more convenient to purchase from the comfort of home. Written by Vint 3, 2014-03-23
.Comfortable sometimes leaky
Generally a good seal, fairly quiet too. As they age skin oils reduce elasticity, so periodic repositioning is required or they leak. Expect 90+ days of use, with quick delivery of replacements! Written by Verified Shopper, 2013-10-01
