ResMed Nasal Mask Assembly Kit - AirFit N20

The ResMed AirFit N20 Nasal Mask Assembly Kit combines an advanced InfinitySeal cushion with a flexible frame for superior comfort and a secure seal with minimal facial contact. This kit includes the frame, cushion, and elbow; headgear is sold separately or can be added as an option at checkout.

Is This Assembly Kit Right for You?

This is the right choice if you're replacing a worn frame, cushion, or elbow and already have usable AirFit N20 or AirTouch N20 headgear, or if you'd rather build your mask piece by piece. If you need everything in one purchase, add headgear as a checkout option, or see the AirFit N20 Mask with Headgear instead.

Why Choose the AirFit N20 Assembly Kit

InfinitySeal Cushion for a Precise Fit

The InfinitySeal cushion uses "infinity" loops with variable thickness to adapt closely to your nose shape, reducing blowout and providing support at the sides of the nose while relieving pressure at the nasal bridge. The soft, frosted surface is designed to feel natural against skin and maintain a secure seal even at high therapy pressures.

A Frame That Flexes With You

Rather than a rigid shell, the minimalist frame naturally flexes to your face for a custom fit, with integrated padding that adds softness so you can read or watch TV comfortably before falling asleep, without pinching or pressure points.

One-Handed, Quick-Release Elbow

The elbow's squeeze-tabs let you detach the tubing with one hand, useful if you need to get up during the night without fumbling in the dark. It also rotates a full 360° and includes an independent tube swivel, which reduces the drag and pull that can otherwise disturb your seal as you move.

Quiet Venting, Built Into the Elbow

Diffused venting built into the elbow disperses air gently away from you and your bed partner, aiming for ultra-quiet performance rather than a loud, direct air stream.

A Flexi-Tube Built for Movement

The integrated, lightweight Flexi-Tube extends off the frame and stretches and bends with you, maintaining seal and stability across a wide range of sleep positions without dragging or catching on bedding.

AirFit N20 for Her

The AirFit N20 for Her is designed to fit a smaller, more feminine face shape, providing a stable fit and an open field of view. It's available as the "Small for Her" size option on this listing.

Sizing

Available in Small, Medium, Large, and Small for Her. If you're not sure which size fits you best, check ResMed's official sizing guidance before ordering, since full-face and nasal mask fit depends on precise facial measurements rather than general preference.

Frequently Asked Questions

Does this include headgear?

Not by default — this kit includes the frame, cushion, and elbow only. You can add headgear as a checkout option to make it a complete mask, or purchase it separately.

What's the difference between this and the AirFit N20 Mask with Headgear?

This assembly kit is the frame, cushion, and elbow, with headgear as an optional add-on. The AirFit N20 Mask with Headgear includes everything by default in one listing.

Is there a version for women?

Yes. The "Small for Her" size option is designed to fit a smaller, more feminine face shape with a stable fit and open field of view.

How does the elbow help with nighttime movement?

The elbow rotates a full 360° and includes an independent tube swivel, reducing the drag and pull on your mask as you shift positions, and detaches with one hand via squeeze-tabs if you need to get up.

Is this mask quiet?

Yes. Diffused venting built into the elbow disperses air gently away from you and your bed partner for quieter operation.

Do I need a prescription to buy this?

No. This mask assembly kit does not require a prescription.
