Sizing Information: Spring air cushions come in four sizes -- ExtraSmall, Small, Medium & Large. Please review the information below to determine which sizes will work with your current mask:
- AirFit F10 and AirFit F10 For Her masks use two different frame sizes so cushion sizes ARE partially interchangeable. The ExtraSmall-Small frame will fit both Extra Small and Small cushions. The Medium-Large frame will fit both Medium and Large cushions.
- Quattro Air and Quattro Air For Her masks use a different frame for each mask size so cushion sizes are NOT interchangeable. When ordering a cushion you must order the size that is designed to fit your mask frame.
