Meet the Resmed AirFit F40 Full Face Mask—built for those of us who are tired of leaky cushions and bulky full face designs. This CPAP mask features a compact cushion with a flexible seal that sits just under the nose, a promising alternative to old-school masks that leave you feeling claustrophobic.

Best of all, the AirFit F40 has been clinically proven to fit everyone. That's right—a 100% universal fit—thanks to its AdaptiSeal cushion and flexible frame that stay in place even when you toss and turn. That means an easier fit, fewer leaks, and steadier therapy.

Whether you're brand new to CPAP and looking for a full face mask or you've been around the block a few times and just want to try something new, the AirFit F40 is a top contender.

  • Minimal coverage: Under‑nose cushion reduces bulk and bridge pressure.
  • Leak-free seal: AdaptiSeal silicone conforms to your facial contours.
  • Quieter therapy: QuietAir venting diffuses airflow for quieter nights.
  • Freedom to move: Short, swiveling tube helps limit hose tug as you turn.
  • Quick-release headgear: Magnetic headgear simplifies your bedtime routine.
  • Side sleeper-friendly: Supports back, side, and stomach sleeping.

Full face coverage without the bulk—AirFit F40

Minimal bulk, maximum comfort

The F40 is about as light as you can get for a full face mask, meaning less bulk on your face and fewer pressure spots. Its soft AdaptiSeal™ cushion and flexible frame ease pressure around the face and head, while the quiet diffuser vents help light sleepers rest easier.

  • Seals under nose with a soft padded frame
  • Wake up with fewer red marks and irritation
  • Soft cushion gently conforms to your face
  • Low-profile design eases claustrophobia
  • The quietest full face mask–just 20 decibels

Your CPAP routine, simplified

CPAP doesn't have to make life harder. Whether you're disconnecting for a quick bathroom trip, or cleaning your mask after a good night's sleep, the AirFit F40 makes your day-to-day–and your night-to-night–easier.

  • Save your fit with magnetic headgear
  • Quick-release elbow for bathroom breaks
  • Adjust in seconds with easy-to-reach fit tabs
  • Fewer parts means faster cleaning
  • Easy to wear during your nightly routine

Strong, adaptive seal

An AdaptiSeal™ cushion flexes with you to maintain a secure seal—whether you’re on your side or tossing and turning. Multiple cushion and frame sizes make it easier to get the right fit without over-tightening. This mask is stable, secure, and built to stay put.

  • Clincally proven, 100% universal fit
  • AdaptiSeal™ silicone molds to your features
  • Stays sealed even when you move
  • Attached short tube eliminates mask pulling
  • Choose from 3 frame sizes for a better fit
  • 4-point headgear stabilizes the seal
Features

100% universal fit: The AirFit F40 is designed for all face shapes and sizes. According to Resmed's clinical testing, the AirFit F40 achieved a secure seal and comfortable fit for 100% of participants.

Magnetic headgear: The magnetic clips allow for quick and easy fitting or removal of the mask, reducing hassle before bedtime and upon waking. A redesigned quick-release elbow also makes it easier than ever to quickly disconnect for middle-of-the-night bathroom trips.

AdaptiSeal Cushion: The AdaptiSeal silicone cushion adapts to your facial contours, providing comfort and maintaining an effective seal throughout the night, even if you change sleeping positions or toss and turn.

Soft-touch headgear: The F40's headgear is padded with soft, moisture-wicking, and cooling material. As you move your head, the headgear moves with you, and the velcro tabs allow for quick and easy adjustments if needed.

Attached short tube: This mask adds a flexible, full swivel short tube between your mask and CPAP hose. That little bit of slack prevents tugging when you turn or roll over, keeping your seal steady so you’re free to settle into a comfy position for the night.

Easy compatibility: This mask is compatible with all CPAP and BiPAP machines, except for the AirMini. If you’d like to use this mask with the AirMini, you will need to purchase the Zephair Universal Adapter.

Sizing

Choosing your frame size: The AirFit F40 is available in three frame sizes, including small, standard, and large. Most people fit into the standard size, so it's best to start with this headgear and then order the small or large size if necessary.

Selecting your cushion size: Cushion sizes are offered in small-wide, medium, and large. If you do not know your cushion size, we suggest ordering an AirFit F40 Starter Pack, which comes with all three cushion sizes, so you can test them out. You can also check out the sizing guide linked above.

Finding your current cushion size: If you currently own an AirFit F40 and are looking to re-order your current mask size, you can find your mask's cushion size by checking the plastic shell of your mask cushion. On this cushion, you will see an SW, M, or L indicating the size of your cushion.

Care and cleaning

CPAP Mask Replacement Schedule:

  • Cushion: Every 1-3 Months
  • Headgear: Every 3-6 Months
  • Mask Frame: Every 3-6 Months

Daily Cleaning: Disconnect short tube/elbow and hang to drip dry. Wipe or wash cushion/frame daily.

Weekly Cleaning: Fully disassemble, wash each mask part using gentle soap/warm water, rinse thoroughly, and allow everything to air dry before reassembling.

Dishwasher Safety: Do not wash any part of your AirFit F40 mask in the dishwasher.
