The replacement ComfortGel Blue Cushion for the ComfortGel Blue Full Face Mask comes as a single gel cushion in medium size, and doesn't include the SST Flap. The cushion is a perfect match for the ComfortGel Blue Full Face Mask.
The blue gel cushion is soft to the touch and hugs your facial curves for an amazing fit.
Where do I find the size?
To find the size of the full face cushion, turn the mask so that you are looking directly at the bottom of the full face cushion. The full face gel cushion does not have an identifiable size. Use the letter indicated on the silicone flap to determine the size of the gel cushion.
The full face cushion is replaceable. The size of the mask frame must match the size of the full face cushion.
Sizing Indicator Update 2015: In 2015, Philips Respironics changed the sizing indicator on the silicone flap for ComfortGel Blue Series Nasal and Full Face Masks.
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 ComfortGel Blue Full Face CPAP Mask is X1. Please Note: System One Resistance Control is for System One Machines only.
