These Nasal Cushions from ResMed are for use with all Swift FX Nano & Swift FX Nano For Her CPAP/BiLevel Masks. The low profile design minimizes facial contact while the dual-wall construction adds stability, distributing pressure evenly and improving comfort.
Sizing Information: The Swift FX Nano Nasal Cushion is available in three sizes -- Standard, Wide and Small. Any cushion size can be used with any Swift FX Nano or Swift FX Nano for Her Nasal Mask; so if you think that a different size might work better for you than the one you're currently using, all you need to do is purchase a new Swift FX Nano cushion and attach it to your existing headgear and short tube.
Compatibility Information: These Nasal Cushions come standard with all Swift FX Nano and Swift FX Nano For Her Nasal Masks. While the fittings are compatible, nasal cushions are NOT recommended for use with Swift FX & Swift FX Bella Series Nasal Pillows Masks. This is due to subtle differences in the mask design required to position nasal cushions properly against the face.
