Mouth Cushion for Mirage Liberty™ Full Face CPAP Mask

Where do I find the size?

The size of the full face cushion is placed in two locations.

1. With the elbow facing the user, turn the mask to view the left side of the mask frame. The size of the full face cushion is embossed into the silicone cushion along the rounded rim, where the full face cushion and mask frame connect.
2. To find the second location, turn the mask in the same manner, to view the right side of the mask frame. An identifiable, clear letter written above the rim of the full face cushion indicates the size of the full face cushion.

To find the size of the nasal pillow, look for the embossed letter found on the stem of either nasal pillow. The letter indicates the size of the nasal pillow. The removable nasal pillow does not have to correspond with the size of the full face cushion. The small, medium, and large nasal pillows are designed to fit the nasal pillow opening in both the small and large full face cushions to offer the user different options.
