ResMed AirFit X30i Oral Cushion – Standard

Quick answer: This is the genuine ResMed replacement oral cushion for the AirFit X30i oral-nasal mask (part 64308) — the “over-the-mouth” half of the X30i’s unique dual-cushion design. It covers the mouth (giving full-face coverage for mouth breathers) and holds the nasal pillows securely in place, working in tandem with the X30i nasal pillows to deliver a stable seal with an open field of view. It’s a one-size (“Standard”) component that fits all X30i nasal pillow sizes. Nasal pillows, frame, and headgear not included.

What’s included

• 1 × AirFit X30i Standard oral cushion (part 64308)

Nasal pillows cushion, frame, and headgear not included.

About this part

The AirFit X30i is an oral-nasal (“hybrid”) mask with a two-cushion design, and this is the oral cushion — the piece that sits over the mouth. It does two jobs at once:

• Full-face coverage for mouth breathers — it covers the mouth, so people who breathe through their mouth get effective therapy.
• Holds the nasal pillows in place — it cradles and stabilizes the separate nasal pillows cushion, keeping them firmly seated for a consistent, leak-free seal.

Crucially, it does this without covering the bridge of the nose or blocking your line of sight — so you keep the open field of view (reading, TV, glasses) that pillow users like, with the coverage and stability of a full face mask. It also carries ResMed’s QuietAir™ diffused venting for quiet exhalation.

One size: the oral cushion is a single “Standard” size designed to work with all X30i nasal pillow sizes (Small, Medium, Large) — so you match your fit with the pillows, and the oral cushion stays the same.

Replacement schedule: because the X30i is an oral-nasal mask, ResMed says the oral cushion (and the nasal pillows) may be replaced up to twice a month for best hygiene and seal — more often than a typical full face cushion.

Compatibility: this oral cushion is exclusive to the AirFit X30i. Note the X30i shares its frame and headgear with the AirFit F30i, so the X30i oral cushion + nasal pillows combination can be fitted onto an F30i frame in place of the F30i full face cushion.

It covers the mouth (full-face coverage for mouth breathers) and holds the nasal pillows securely in place — while keeping the bridge of the nose and your line of sight clear.

Does it fit other ResMed masks?
No — it’s exclusive to the X30i. (The X30i shares its frame and headgear with the F30i, so the X30i cushions can go on an F30i frame.)
