3. Setup and Installation
To install the replacement cushion, ensure your AirFit N20 mask frame is clean and dry.
- Align the new silicone cushion with the mask frame. The cushion has specific grooves and attachment points that correspond to the frame.
- Gently press the cushion onto the frame, ensuring all edges are securely seated. You should feel a slight click or firm attachment as it locks into place.
- Verify that there are no gaps or misalignments between the cushion and the frame, as this can lead to air leaks during therapy.
