The replacement Nasal Cushion for the Wisp Nasal Mask comes as a single silicone nasal cushion in your desired size: petite, small / medium, large, or extra large. All four sizes fit on the Wisp Nasal CPAP Mask.
The Wisp cushion is small and lightweight with minimum facial touchpoints for a maximum seal.
Where do I find the size?
To find the size of the nasal cushion, look at the bottom of the silicone cushion, where the mask frame and nasal cushion connect. A large, black letter will indicate the size of the nasal cushion.
System One Resistance Control Tips
If using a Respironics System One machine, a system one resistance control number from Respironics can be set to allow the machine to compensate for different mask types. The resistance control number for the Wisp Nasal CPAP Mask is X1. Please Note: System One Resistance Control is for System One Machines only.
