The ComfortCurve Nasal Interface System comes complete with 3 size cushions (S, M, L), headgear and our exclusive tubing system. It is packaged in an attractive pouch for convenient travel.

Every ComfortCurve cushion contains a blue plastic clip with 3 blue teeth that are used to attach the cushion to the white cross tube.

The ComfortCurve cushion is designed to be worn under the nose for a seal that cradles or saddles the base of the nose.

The ComfortCurve cushion is assembled onto the cross tube by lining up the 3 blue teeth with the corresponding notches on the cross tube.

To attach the cushion, wrap it around the cross tube as shown.

The cushion should audibly snap into place. Be sure to firmly press the cushion onto the cross tube so it is attached at all 3 points. Please note: the cushion may create unwanted leak if not completely attached.

To remove the nasal cushion from the ComfortCurve, simply grasp the top of the cushion and peel it away from the cross tube.

By removing the bridge and attaching the cushion, it is easy to see how the cushion attaches to the cross tube. Note: this photo illustrates how the cushion attaches in order to use the ComfortCurve, the bridge would also need to be assembled.
