Important Tips

Where do I find the size?

The size of the Liberty™ mask frame is determined by the size of the cushion. The mask frame does not have an identifiable size, but the cushion attached to the frame directly corresponds to the size of the mask frame.

  • Small Liberty™ Mouth Cushion fits ONLY Small Liberty Mask Frame
  • Large Liberty™ Mouth Cushion fits ONLY Large Liberty Mask Frame

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.

For help with selecting the proper size cushion, use ResMed's Mirage Liberty Hybrid Sizing Guide.
