Cushion for FlexSet and Serenity Nasal CPAP Masks

These cushions will fit the frame of the FlexSet or FlexSet II Nasal Mask and the Serenity or Serenity II Nasal Mask.

DeVilbiss changed its naming convention as of December 2012.

• Shallow is now referenced as Small
• Standard is now referenced as Medium

Where do I find the size?

The cushion is stamped with the name "SERENITY" only. The cushion does not have the name FlexSet stamped on it.

• Serenity is stamped along the lower edge of the cushion, along the long part that will rest above the upper lip. The Gel cushion has the letter G stamped after Serenity.
• The Shallow cushion has the letter S stamped after the word Serenity.
• The Standard cushion has only the word Serenity stamped on it.
