AirFit F20 Full Face CPAP Mask by ResMed

Key Features:

  • Magnetic clips - hassle-free mask removal and reattachment without compromising fit
  • Quick-release elbow - disconnect mask from CPAP hose without removing the mask
  • InfinitySeal cushion - minimizes leaks and blow-outs even at high pressures
  • Open-faced design - lack of an obstructive forehead support allows users to watch TV or read before sleep
  • Flexible and compact frame - opens up the field of view, reducing feelings of claustrophobia
  • Modular design - interchange the AirFit F20 silicone cushion with the AirTouch F20 foam cushion
  • Whisper quiet - QuietAir Vent diffuser reduces operation noise to just 21 decibels

InfinitySeal Cushion
The AirFit F20 InfinitySeal cushion is designed to accommodate a wide range of facial structures and to provide a secure seal under varying pressure levels. The cushion's sophisticated engineering offers significant support around the nose, which effectively reduces the occurrence of disruptive mask leaks and blow-outs, contributing to a better sleep experience. With the AirFit F20 cushion, users can experience a comfortable and effective therapy session, ensuring a good night's sleep.

Plush Headgear and Magnetic Clips
The AirFit F20 headgear is designed for ultimate comfort and stability, no matter the sleeping position. The flexible headgear's four-way adjustable design ensures it stays put all night long, which minimizes readjustments and interruptions to your sleep.

Additionally, the magnetic headgear clips provide an effortless and convenient way to attach the headgear to the frame, making it easy to put on and take off the mask. This feature allows for quick and hassle-free removal and reattachment of the mask without readjusting the headgear, compromising that perfect fit.

Note: If you have a metallic medical implant, such as a pacemaker, defibrillator, etc., we recommend choosing a mask that does not use magnetic clips.

Quick-Release Elbow for Ultimate Convenience
The AirFit F20 Full Face Mask features a specially designed quick-release elbow that offers unparalleled convenience. This innovative feature allows users to disconnect the mask from the CPAP hose without removing the mask itself, providing a hassle-free experience when you need to get up during the night.

Simply squeeze the sides of the quick-release elbow to detach it, along with your CPAP hose, from the front of the AirFit F20. Upon your return to bed, you can quickly reconnect the elbow to the front of the mask by pushing the quick-release elbow in until you hear an audible click. The AirFit F20's quick-release elbow eliminates the need to readjust any straps or components so users can minimize interruptions to their sleep apnea treatment.

Flexible, Open-Faced Frame
Shaped like adaptive wings, the F20 mask frame runs along the cheeks and extends up the sides of the forehead. This innovative design allows ResMed to eliminate the forehead support bar without compromising mask seal, providing users with an open field of view which not only reduces feelings of claustrophobia, but also makes it possible to watch TV or read before bed.

Whisper Quiet Operation
ResMed's F20 CPAP mask features innovative QuietAir Vent technology which reduces operation noise to an impressively low 21 decibels that is truly "whisper quiet." A ring of small ports on the mask's quick-release elbow gently disperses exhaled air away from the user and bed partner, minimizing noise and draft to prevent unpleasant awakenings.

Multiple Headgear and Cushion Sizes Available

The ResMed AirFit F20 Full Face Mask is available in three cushion sizes - Small, Medium and Large. All three cushion sizes come with a Standard sized headgear. ResMed also offers Small and Large headgear sizes which are available separately.

First-time AirFit F20 users should consider using the AirFit F20 Sizing Gauge to determine their cushion size as CPAP mask cushion sizes are not identical across manufacturers. The Sizing Gauge can be found under the "Size Gauge" tab on this webpage. For accurate sizing, please ensure the Sizing Gauge is printed to scale and the measurement is taken with the aid of a mirror or a second pair of eyes.

Interchangeable Cushions

The AirFit F20 Full Face Mask is also compatible with ResMed's AirTouch F20 Memory Foam Cushion which offers a light, breathable seal and ultra-soft performance.

Note: The AirFit F20 Mask Frame is compatible with all sizes of AirFit/AirTouch F20 Cushions.


How often should I replace the AirFit F20 Full Face Mask?
The F20 mask frame, elbow and headgear should be replaced every 6 months while the AirFit F20 silicone cushion should be replaced every 2 to 3 months. We encourage more frequent cushion replacements compared to other mask parts because the silicone softens with use (i.e., from contact with face oils, dead skin cells etc.) which inevitably compromises mask seal.

How do I clean the ResMed AirFit F20 mask?
Daily: cushion
Weekly: frame, elbow, headgear

Disassemble the mask before cleaning and hand wash all parts with mild soap and water. Use a soft bristle brush to gently scrub the vent ports on the quick-release elbow. Rinse each part thoroughly under running water and air dry away from direct sunlight. Squeeze excess water out from the headgear before laying it flat to air dry.

Regular mask cleaning helps control bacterial growth and prolongs the lifespan of the silicone cushion. CPAP wipes can be used in place of soap and water for quicker, hassle-free mask maintenance.

How do I determine what size cushion I need for the AirFit F20 mask?
Please use the Sizing Gauge that is available under the "Size Gauge" tab above to determine your cushion size.

How do I disassemble/assemble the AirFit F20 mask?

  1. Remove the elbow from the frame.
  2. Unclip the magnetic clips from the frame.
  3. Undo upper and lower headgear tabs.
  4. Pull the headgear away from the frame and slide the magnetic clips off the headgear straps.
  5. Pull the cushion away from the frame by holding the frame in one hand and the hard plastic portion of the cushion in the other. If your mask has never been disassembled, you will need to exert some force to pull the cushion off.


  1. Attach the cushion to the frame by lining up the circular opening on the cushion to the frame and pushing until the pieces are connected.
  2. Thread the magnetic clips onto the bottom headgear straps. Fold over the straps to secure the Velcro.
  3. Thread the upper headgear straps through the slots in the frame. Fold the Velcro tabs over to secure.
  4. Push the elbow into the front of the mask until an audible click is heard.

I order the mask when I received it and open it it seen like it had been used and had a funny smell i call the very next morning the lady had an attitude when i told her I wanted my money back now i have to pay shipping to return it I don’t know if someone had previously returned the mask and they sold it to me but u could even see a fingerprint on the mask save your money and time and buy it somewhere else they don’t appreciate the business and I can’t use something that who knows who touch it or use it especially when u have to put it in your face.

I eagerly awaited receipt of my new F20, expecting that Resmed would have improved on the F10, which I find ok except the cushions do not last long and the headgear is pretty hopeless as usual. However, although I followed Resmed's instructions, I found that the only way to stop leakage was to have the mask fairly tight. In turn this made the bridge of my nose and cheeks sore by morning. I think the cushion is awful and the plastic of the mask very harsh. The mask is very noisy too and it is easy to dislodge the connecting elbow. The headgear is fine and would be better adapted to the F10. Overall, it will be chucked into the box with other masks that I find difficult to use. A waste of money on my part.

I don't usually write reviews but the only review on this site was super negative. I didn't think it was that bad. I don't think there will ever be a perfect full face mask but this was the best I've ever had. I find with all the full face masks I've tried that you have to really cinch down the straps to limit/stop the leaks. This can cause you to have a minor sore spot on the bridge of your nose and of course stap marks. This is the first mask I've had that doesn't leak and you know what that means, a good sleep! I'll take the minor and temporary nose irritation until they have improved this issue.

Subject: AirFit F20 Full Face CPAP Mask - ResMed
I had difficulty getting a good seal at first. When I got past that I found my AHIs quadrupled. I am not using the mask anymore. Since I had already used my Mask Assurance in the last 12 months I am out the money.

Hi there, I'm sorry this mask did not work out for you. If your AHI was increasing it could be because the the lower 2 straps are too tight. When a full face mask is too tight and causing your lower jaw to recede this may actually cause obstructions. Your device may have a mask fitting option which may be helpful. Please give us a call for assistance.

Subject: F20 full mask
Normally I have used a nasal pilly but with my nasal polyps getting worse I wasn't able to breathe through my nose. I decided to try the ResiMed F20 full mask since with the correct adapter I can use it on my Dreamstation and with the Air Mini elbow with my travel Air Mini. The fit is good on the F20 and I sleep great (even being a side sleeper). Although the parts are ridiculously expensive that is a problem with med equipment manufacturers gouging users.

I am using the ResMed Airfit F20 full face CPAP large mask with headgear. I like it except that in order to get a good seal (NO leaks) it must be worn tight on my face. It also causes soreness at the bridge of my nose when I use or. remove the mask. ResMed, if you can correct this problem the mask would be great I am going to try a medium size mask and hope this will correct the problem. Send this to ResMed for corrections to the mask, please. Thank you.

Full Face Mask ResMed A20. It's excellent. I'm new to this whole CPAP thing, and I was about to give up on it using the nose pillow. I was having to decide whether I would sleep or use the CPAP -- there was no way to do both at once. The full face mask fixed that problem. I'm sleeping well with it, and I can use the CPAP as I should. Delivery was very fast. Totally happy with the transaction.

Is there a full face mask that has the forehead attached to face mask. It does not stay forward on my head and then leaks around the mask. I have to tighten it so much that it causes a red mark on the bridge of my nose that takes hours to go away.

Thank uou

My account number is 646692. The full face mask seems to be okay however I was not happy that the mask came in an unsealed container or plastic bag. I am still working with the correct air pressure to achieve full satisfaction. Thank you for the concern.

Does this mask make you feel claustrophobic?
Everyone's response to a full face mask is different. That is why there are so many to choose from. Give us a call and we will be happy to discuss masks with you.
What is the difference in size for ResMed small Airfit 20 and the small Airfit 20 for her?
For Her masks have a slightly smaller headgear and are a different color.
Will this fit my airsense 10
Yes it will.
I'm having it very very hard to find a full face mask I can wear. I love the Airfit 20 ( memory foam) but I need an XS.
Where can I find a mask that would work as well
Thank you
I am sorry this mask only comes in a small. There is not an xsmall at this time available.
How are the straps attatched to the mask, I have a full mask and the clips, clip on and sometimes my hands don't work too well,,
Here is a great video that will show how to put the mask headgear together. Thank you
I use AirFit F20 full face mask. During sleep there is air leak which in turn leads to very parched dry mouth, I believe, and disrupts sleep. Would AirTouch with foam mitigate or eliminate this problem? Thank you.
Hi there, if you are already wearing a full face mask the airtouch would not mitigate leak. It helps with sensitive skin. I would suggest a few things. Ensuring the mask is being washed. Ensure the mask size is correct, the top of the mask should sit on the bridge of your nose and the bottom of the mask just under your lower lip. If you do have facial hair you want to ensure that you are shaving, facial hair will not create a seal on the face. Also ensure the mask is adjusted and tightened evenly around, you want to be able to fit two fingers under your strap and if you cant it might be too tight.
