ResMed AirFit N30i Under-Nose Nasal CPAP Mask - Top-of-Head Hose

The ResMed AirFit N30i is a nasal CPAP mask that offers 360° freedom of movement with its top-of-head tube connection. Designed for all sleeping positions, it features an under-the-nose cradle cushion and a self-adjusting frame. The product on this page is the AirFit N30i version with a standard (multi-hole) vent.

Why Choose This Mask?

Unlike traditional masks, the ResMed AirFit N30i allows you to move freely throughout the night thanks to its top-of-head tube connection. Its minimalist design makes it comfortable to use while watching TV or reading a book. The under-the-nose silicone cushion prevents red marks on the bridge of your nose and is an ideal solution for claustrophobic users.

Design and Comfort Features

The most prominent feature of the mask is its under-the-nose cradle cushion. This design eliminates pressure points by avoiding contact with the nasal bridge. The redesigned mask cushion is made entirely from soft material; it conforms better to facial contours than the old rigid-bodied cushion and maintains its seal when you turn your head.

The 360° swivel quick-release elbow allows you to disconnect the tube without removing the mask when you get up at night. The self-adjusting (SpringFit) frame system adapts to your natural facial movements and requires no constant adjustment.

Air Vent

• Standard (multi-hole) cushion: Vents your breath out through numerous small holes. The product on this page is this version.

Compatible Devices

The ResMed AirFit N30i can be used with CPAP, APAP, and BiPAP devices featuring a standard 22 mm conical tubing connection:

• ResMed AirSense 10 series
• ResMed AirSense 11 series
• ResMed AirCurve 10 / 11 series
• Philips DreamStation series
• Fisher & Paykel ICON / SleepStyle series
• Other CPAP and BiPAP devices with standard tubing connection

Important Note: Not compatible with ResMed AirMini. The AirMini only works with its specifically designed mask setups (such as AirFit P10 for AirMini, AirFit N30 for AirMini, AirFit N20 for AirMini); in these setups, the vent module is device-specific. The AirFit N30i is not on this list.

Sizing Guide

The AirFit N30i has two separate measurements: the mask cushion and the frame. The cushion is chosen based on the width of your nostrils, and the frame is chosen based on your head size.

Mask cushion sizes:

Measurement Method: Print ResMed's sizing template at 100% scale, cut it out, and hold it against your nostrils. Choose the cushion size that aligns with the template. You can also request the template from us; if you're unsure, we can assist you by phone.

Frame size: Two sizes are produced - Small and Standard.

• If the frame slides back over your head or sits too close to your ears, the Standard is too large; switch to Small.
• If the frame falls forward or sits too close to your eyes, the Small is too small; switch to Standard.

Care and Cleaning

Daily:

• Hand wash the mask cushion with warm water and a mild (neutral) liquid soap
• Rinse thoroughly and air dry in a place away from direct sunlight; do not use a towel

Weekly:

• Disassemble the parts: cushion, frame, elbow, headgear
• Hand wash all parts, including the headgear, with warm water and mild soap
• Rinse thoroughly with plenty of water and air dry

Do not use: Vinegar, bleach, alcohol, chlorine, or soaps containing moisturizers and antibacterial agents, as well as ozone (SoClean etc.) and UV cleaning devices. These can harden the silicone, discolor it, and invalidate the manufacturer's warranty. ResMed only recommends warm water and mild detergent.

Manufacturer's recommended replacement periods:

• Mask cushion: monthly
• Frame system: every 3 months
• Headgear: every 6 months

These intervals represent the upper limit for maintaining seal and hygiene and may vary depending on usage intensity. If the cushion starts to become oily, dull, lose its flexibility, or leave marks, replace it without waiting for the recommended period.

The frame is modular: the AirFit P30i nasal pillow can also be attached to the same frame, allowing you to switch between a cradle mask and a pillow mask.

Frequently Asked Questions

In which sleeping positions can the ResMed AirFit N30i be used?

Thanks to its top-of-head tube connection, you can comfortably use it in back, side, and even stomach sleeping positions. The 360° swivel elbow prevents the tubing from tangling.

How quiet is the mask?

The version on this page features a standard multi-hole vent, where your breath is exhaled through numerous small holes. The air vent is directed forward from under your nose, meaning it won't blow directly onto your bed partner.

What should I do if the mask leaks air?

First, ensure the cushion size is correct. The headgear should not be too tight or too loose. If the cushion is worn, replace it. If the problem persists, try a different cushion size, and if necessary, a different frame size.

Can bearded users wear this mask?

Yes, the under-the-nose contact area does not interfere with beards. However, it is recommended that there isn't very long facial hair in the area where the cushion sits. Short beards usually do not cause problems.

Why is it not compatible with AirMini?

The AirMini works with its own mask setups, where the air vent and humidification (HumidX) module are device-specific. The AirFit N30i is not among these setups. For AirMini, choose AirFit P10 for AirMini, AirFit N30 for AirMini, or AirFit N20 for AirMini.

What should be considered during first use?

An adaptation period of the first 3-5 nights is normal. Ensure the cushion size is correct. Do not overtighten the headgear; it should only be snug enough to prevent air leaks.

Pros and Cons from an Expert's Perspective

Pros:

• Full freedom of movement with a top-of-head tube connection
• Pressure-free, mark-free design that avoids the nasal bridge
• Ideal for wearing glasses, watching TV, and reading
• Suitable for claustrophobic users
• Modular frame: can also be used with the P30i pillow cushion

Cons:

• Incompatibility with AirMini device
• Not suitable alone for mouth breathers (may require a chinstrap or full-face mask)
• Cushion and headgear replacements sold separately

Field Tip: In my 20 years of experience, the most common mistake patients make when first using the N30i is overtightening the headgear. The cushion should only make gentle contact under the nose; overtightening out of concern for leaks can fold the silicone and, paradoxically, lead to air leaks.
