Cushion for D100 Nasal CPAP Mask

Where do I find the size?

The Cushion for the D100 Nasal CPAP Mask mask is replaceable.

To find the size of the nasal cushion, turn the mask to view the flat bottom of the mask frame and nasal cushion. The words "S M A L L," "M E D I U M," or "L A R G E" will be found near the lip that secures the cushion to the mask frame.
