Setup and Assembly
Proper setup of your AirFit N30i Standard Frame System is crucial for effective and comfortable CPAP therapy. Follow these steps to assemble and prepare your mask.
1. Check Your Size

This image illustrates how to verify the correct size for both the nasal cradle cushion and the frame system. Ensure your cushion size (e.g., Medium) matches the frame for an optimal fit.
The AirFit N30i system comes with a medium nasal cradle cushion. It is important to ensure that the cushion and frame size are appropriate for your facial structure to achieve a proper seal and maximize comfort. Refer to the sizing guide provided with your complete CPAP mask system or consult your healthcare provider if you are unsure about your size.
2. Assembling the Frame System

This diagram shows the AirFit N30i Frame System, emphasizing its tube-up design which allows for greater freedom of movement during sleep.
- Connect the nasal cradle cushion to the frame. Ensure it clicks securely into place.
- Attach the elbow to the top of the frame. The elbow swivels to allow for hose connection from any direction.
- If you are replacing an existing frame system, detach your headgear from the old frame and reattach it to the new frame. The headgear is sold separately and is essential for securing the mask.
Operating Instructions
Once assembled, the AirFit N30i Standard Frame System is ready for use with your CPAP machine. Follow these guidelines for proper application and comfortable wear.
Wearing Your Mask

This image shows a user comfortably wearing the AirFit N30i mask, highlighting how the top-of-head tubing allows for unrestricted movement during sleep.
- Hold the nasal cradle cushion against your nose.
- Pull the headgear over your head, positioning the top-of-head tubing over the crown of your head.
- Adjust the side straps of the headgear to achieve a snug but comfortable fit. Avoid overtightening, as this can cause discomfort and leaks.
- Connect the CPAP hose to the elbow at the top of the mask.
- Turn on your CPAP machine and check for any air leaks around the cushion. Gently adjust the mask or headgear straps if necessary to minimize leaks.
The unique tube-up design of the AirFit N30i allows you to sleep in various positions, including on your side or stomach, without the hose getting in the way. This design promotes greater freedom of movement and a more natural sleep experience.
