ResMed AirFit F20 Full Face CPAP Mask

The AirFit F20 is one of the most widely recommended full face masks in the ResMed range and it’s easy to understand why. Whether you're new to CPAP therapy or switching from another mask style, the F20 is designed to make your transition as smooth and comfortable as possible. What really sets it apart is its adaptability. Thanks to ResMed’s InfinitySeal silicone cushion, the F20 moulds to the natural contours of your face and adjusts to movement throughout the night. That’s particularly helpful for people who sleep on their side, change positions often or breathe through their mouth. And if you’re sharing a bed, your partner will appreciate the QuietAir vent technology. Integrated into the mask elbow, this diffuser brings sound levels down to a whisper-quiet 21 decibels, quieter than rustling leaves or a ticking clock. It gently disperses exhaled air in multiple directions, helping minimise noise and airflow drafts. Finally, the mask’s flexible frame sits low beneath the eyes, keeping your line of sight clear so you can comfortably read, wear glasses or watch TV while getting ready for bed. Simply put, the AirFit F20 is a dependable, user-friendly option that balances stability, comfort and quietness.

Yes, the AirFit F20 is universally compatible with nearly all CPAP, APAP and BiPAP devices from major brands. If your machine uses standard 22mm CPAP tubing, the F20 will fit right in – no special adapters required. If you're using a ResMed device like the AirSense 10 or AirSense 11, you'll benefit from additional features like mask detection, SmartStart and therapy tracking through the myAir app. These integrations help your machine recognise the F20, optimise therapy delivery and provide useful feedback about your mask seal and nightly usage. The F20 is also fully compatible with ResMed’s ClimateLineAir heated tubing, which helps prevent condensation in cooler rooms and keeps your therapy air at a comfortable, consistent temperature throughout the night. Whether you're upgrading from another mask, trialling full face therapy for the first time or just looking for something reliable and versatile, the AirFit F20 will likely be a seamless fit.

Choosing the right size is key to comfort and therapy success. The AirFit F20 is available in three sizes – Small, Medium and Large – to suit a wide range of facial shapes. It also comes in a ‘For Her’ variant designed with a smaller size range and lavender accents for users who prefer a more tailored fit. To get the perfect fit, we recommend you book a mask fitting appointment with one of our CPAP consultants. This is especially important if you're new to CPAP or switching from a different mask style. While many users are able to fit the mask confidently on their own, ResMed includes a detailed user guide with diagrams and instructions and we also offer easy-to-follow fitting video online to walk you through the process.

Yes, you can absolutely switch between the AirFit F20 and the AirTouch F20, as both use the same frame and headgear. The difference lies in the cushion. The AirFit F20 comes with the InfinitySeal silicone cushion, which is soft, durable and easy to clean. The AirTouch F20, on the other hand, uses an UltraSoft memory foam cushion, which conforms more closely to your face and provides a plush, gentle seal – ideal for sensitive skin or users prone to red marks. Many users like to alternate between the two – using the memory foam in cooler months when skin tends to dry out or the silicone version in warmer months for breathability. Cushion swaps take only seconds and you don’t need to purchase a second mask to try them both.

Magnetic clips are designed to make your mask easier to handle, but they aren’t suitable for everyone. If you or someone who will be in close contact with you while wearing the mask has certain medical implants or metal in the body, magnetic clips may not be safe. Please read the important safety information below before choosing a mask with magnets: Masks with magnetic components are contraindicated for use by patients where they, or anyone in close physical contact while using the mask, have the following: Active medical implants that interact with magnets (i.e., pacemakers, implantable cardioverter defibrillators (ICD), neurostimulators, cerebrospinal fluid (CSF) shunts, insulin/infusion pumps) Metallic implants/objects containing ferromagnetic material (i.e., aneurysm clips/flow disruption devices, embolic coils, stents, valves, electrodes, implants to restore hearing or balance with implanted magnets, ocular implants, metallic splinters in the eye)

Regular cleaning keeps your mask working effectively and extends its lifespan. After each use, it’s a good idea to wipe down the cushion with a damp cloth or a CPAP-safe wipe to remove facial oils, makeup or residue that can affect the seal. Once a week, ResMed recommends a full clean:

• Disassemble the mask into its separate components (cushion, frame, elbow and headgear)
• Wash everything – except the headgear – in warm water with a mild, non-fragranced detergent
• Rinse thoroughly to remove all soap residue and let air dry completely out of direct sunlight
• Wash the headgear separately and allow it to dry fully before reassembly

Avoid harsh soaps, antibacterial wipes, bleach or alcohol-based cleaners, as these can degrade the materials and shorten the life of your mask. If you're not sure whether you're cleaning your mask properly, refer to the instructions in the user guide or check out our video walkthroughs which demonstrate the process step by step.

Like most CPAP masks, the AirFit F20 is built to last but regular wear-and-tear means some components will need replacing on a schedule to keep things working properly. Here’s a general guide: Cushion: Replace every 1 to 3 months or sooner if you notice leaks, yellowing or reduced comfort Headgear: Replace every 6 months, especially if it becomes stretched, frayed or loses its shape Frame and elbow: These tend to last longer but should be replaced if cracked, warped or no longer secure If your mask suddenly feels uncomfortable, starts leaking or seems noisier than usual, it might be time to replace a component. Many CPAP providers offer replacement kits or subscription bundles that include everything you need to stay on track.

For optimal performance, your CPAP machine should generally be placed on a bedside table or a stable surface at about the same level or slightly lower than your head. This helps reduce the risk of rainout (water condensation in the tubing). If your machine is too high or too low, you may notice issues like water collecting in the tubing or uneven airflow. Keep the machine on a flat, stable surface with enough room for air circulation.
