ResMed AirFit F40 Frame System (without Headgear)

Description

Quick answer: This is the genuine ResMed frame system for the AirFit F40 — ResMed’s newest compact under-the-nose full face mask. It includes the frame, the AdaptiSeal™ silicone cushion, and the quick-release elbow, ready to pair with your existing F40 headgear — a cost-effective way to refresh the frame and cushion when your headgear is still good. Note: headgear is not included, and the F40 frame contains magnets (see the important safety note below). Headgear not included.

⚠️ Contains magnets. The AirFit F40 has magnets in the frame and lower headgear clips (field strength up to 400 mT). Magnets are contraindicated for people with certain medical implants — see the safety section before ordering.

What’s included

• 1 × AirFit F40 frame (with magnetic clips)
• 1 × AdaptiSeal™ silicone cushion (in your selected size)
• 1 × quick-release elbow

Not included: headgear (acquire separately if needed).

About this part

The AirFit F40 is ResMed’s newest minimalist full face mask — a slim, low-profile mask that seals under the nose rather than over the bridge, with a soft, flexible AdaptiSeal™ silicone cushion that adapts to the face and holds a secure seal even as you move. It’s designed for side sleepers, mouth breathers, and glasses-wearers, and for anyone who finds traditional full face masks bulky or claustrophobic. Fitting is quick thanks to four adjustment points and magnetic clips.

This frame system is the structural core: the cushion seats into the frame, the headgear clips to its four points, and the quick-release elbow connects the tubing. Buying the frame system (frame + cushion + elbow) lets you refresh those parts while reusing your existing F40 headgear — cheaper than a complete new mask. It’s supplied without headgear.

Important: magnets & implants (read before ordering)

The AirFit F40’s magnets are located in the frame and lower headgear clips, with a field strength of up to 400 mT. Masks with magnetic components are contraindicated for people — or anyone in close physical contact with the mask — who have:

• Active medical implants that interact with magnets — e.g. pacemakers, implantable cardioverter defibrillators (ICDs), neurostimulators, cerebrospinal fluid (CSF) shunts, insulin/infusion pumps.
• Metallic implants/objects with ferromagnetic material — e.g. aneurysm clips/flow-disruption devices, embolic coils, stents, certain valves, electrodes, hearing/balance implants with magnets, ocular implants, metallic splinters in the eye.

Keep the mask magnets at least 6 inches (150 mm) away from implants or devices that may be affected. If this applies to you or someone in close contact with your mask, follow the full contraindications in the mask’s user guide and consult your physician.
