Key Features

  • InfinitySeal silicone cushion – Self-adapts to your facial contours for a consistent, leak-minimizing seal across different sleeping positions.
  • Magnetic headgear clips – Snap on and off instantly without losing your headgear adjustment — no re-fitting needed during the night.
  • Flexible frame – Moves with you during sleep, reducing displacement and pressure points for active and side sleepers.
  • Quick-release elbow – Disconnects from the hose without removing the mask, making nighttime trips easier.
  • Clear line of sight – Low-profile design keeps your vision unobstructed for glasses, reading, or TV before bed.
Description

The ResMed AirFit N20 Nasal CPAP Mask delivers a secure, comfortable fit for a wide range of facial structures using ResMed's InfinitySeal cushion — a soft silicone design that self-adapts to your facial contours to minimize leaks and pressure points through the night. Available in Small, Medium, and Large, with a FitPack option that includes all three sizes.

Magnetic clip headgear makes on and off effortless — disconnect without readjusting your fit, reconnect in seconds. The flexible frame moves with natural sleep position changes, making it a reliable choice for active sleepers and side sleepers who need a nasal mask that stays in place. A quick-release elbow lets you disconnect from the hose without removing the mask entirely.

The low-profile under-nose frame keeps your line of sight clear for reading or watching TV before bed, and the soft plush headgear reduces facial pressure during extended wear. Compatible with most CPAP and BiPAP machines — and with the AirMini using an additional connector.

Product questions & answers

What sizes are available and which should I choose?
The AirFit N20 comes in Small (63503), Medium (63501), and Large (63502). Medium fits most average users. If you're unsure, the FitPack (63535) includes all three cushion sizes so you can test the fit before committing to replacements.

What is the InfinitySeal cushion made of?
The InfinitySeal cushion is made from soft silicone — not memory foam. It flexes and adapts to your facial contours to create a seal that holds through movement during sleep. If you prefer a memory foam cushion, the ResMed AirTouch N20 uses UltraSoft memory foam and is a direct alternative.

Is this mask compatible with the ResMed AirMini?
The AirFit N20 can be used with the AirMini travel CPAP with the addition of a compatible AirMini connector, sold separately. Without the connector, it is not directly compatible.

Can I use this mask with a BiPAP machine?
Yes. The AirFit N20 is compatible with most CPAP and BiPAP machines across major brands. Confirm your machine's hose connection type before ordering if you are unsure.

How often should I replace the cushion and headgear?
Replace the cushion every 1–3 months depending on wear. Replace the headgear every 6 months. Signs it's time to replace: the cushion feels stiff or loses its shape, or you notice more leaks than usual despite a properly adjusted fit.

Does Order Your Supplies provide an insurance receipt for this purchase?
Most products are sold as cash-pay purchases. After your order is placed, you can request an insurance-ready receipt that includes the item description, cost, and HCPCS code. You can then submit it to your insurance provider to ask about out-of-network or self-purchase reimbursement if your plan allows it.
