Replacement pillows for the Swift FX Mask System. The Swift™ FX nasal pillows are designed with dual-wall flaps with improved support and comfort. The cushion's base is outfitted with an integrated flexible chamber that provides stability for side sleepers. This added flexibility accommodates movement and a reliable seal at high therapy pressures.
There is not a sizing guide for the Swift FX pillows but medium fits most men, and small fits most women.
