ResMed AirFit X30i Oral Nasal CPAP Mask

The X30i frame comes in small, standard, and large sizes.

• The Standard frame should work well for the majority of wearers.
• If you have a wider face or strong bone structure, consider sizing up.
• Petite users may prefer the small frame, available with assembly kits.
• If your mask feels too loose or too tight, adjusting your frame size may help.

Finding Your Cushion Size

The X30i cushion includes two components: a universal-fit oral cushion and interchangeable nasal pillow cushions.

• The mouth cushion is one-size-fits-most and works with all X30i and F30i frames.
• Your mask kit includes small, medium, and large nasal pillows—try each to find the size that gives you the best comfort and seal with minimal leaks.

The AirFit X30i will work with any standard-sized tubing connection, meaning it is natively compatible with most CPAP machines, even if you're using heated tubing.

If you're interested in pairing the AirFit X30i with an AirMini Travel CPAP, you'll need the Zephair Tubing Adapter and a regular, unheated CPAP hose like Resmed's SlimLine Tubing.

Yes, the AirFit X30i and F30i use an identical frame, so you can swap seamlessly between the F30i's nasal cradle cushion and the X30i's hybrid nasal pillow design in seconds.

For the most hygienic, consistent, and comfortable therapy, Resmed recommends replacing the X30i's nasal pillows twice a month. Typically, you can use the same set of nasal pillows for 1 to 3 months on other masks. The X30i's oral cushion should be replaced every 3 to 6 months for consistently comfortable therapy.

For most people, the Standard frame should fit well. If you typically use smaller hats or headgear, or have a generally smaller head size, you may be better off with the small frame. Similarly, if you typically wear larger hats or headgera, or have a generally larger head size, you may be better off with the large frame.
