InfinitySeal™ Nasal Cushion

The AirFit™ N20 with InfinitySeal™ is an adaptive nasal cushion designed to help maintain a strong seal during therapy, even if positions change. The cushion has varying levels of thickness to better conform to the user's nasal structure, helping it fit a wider range of users.

Soft, Flexible Frame

The AirFit™ N20 frame adds more adaptability to the mask with its flexible design. The frame will flex depending on the sleeping position to help ensure the cushion remains in ideal placement. The frame has integrated padding for extra comfort.

Open Line of Sight

As a result of the frame resting below the eyes and not using a tradition forehead support, the Airfit™ N20 leaves line of sight open. The unobstructed view means nighttime TV watching and reading with the mask on is an option.

Quick Release Elbow

The AirFit™ N20 nasal mask features a quick release elbow allowing for the mask to be disconnected quickly and easily. Simply press the buttons on either side of the elbow to disconnect the mask from the short tube and CPAP hose.

Important Tips

Cleaning Tips

The components should be washed regularly in warm water with a mild detergent and allowed to dry out of direct sunlight as follows:

  • Daily: Cushion, Elbow, Short Tube
  • Weekly: Frame

When washing the frame, squeeze it during rinsing to ensure all soapy water has been rinsed out. Also, after rinsing, squeeze the frame to eliminate excess water for faster drying.

Sizing Tips

For choosing the correct size, please use the sizing guide found towards the top right of this page. Measure the ruler on the printed sizing guide to ensure it printed properly and to scale. The sizing guide uses the width of the nose as its determining factor.

The AirFit N20 has three interchangeable cushion sizes - small, medium, and large. Each size cushions easily clicks into the same mask frame so users can swap between them with ease for more flexibility. The size can be found on the bottom of the cushion, marked either S, M, or L.

Cushion Tips

The N20 cushion size is printed in black lettering on the bottom of the cushion. When installing the cushion, ensure the size indicator is facing down. The cushion should not be placed on the frame upside down.
