AirFit F20 Full Face CPAP Mask by ResMed

InfinitySeal Cushion
The cushion is designed to fit a variety of facial structures while maintaining a strong seal at a range of pressures. Engineered to provide significant support around the nose, the F20 cushion prevents blow-outs and disruptive mask leaks.

Plush Headgear and Magnetic Clips
The headgear is designed for extra comfort and stability, providing a better night's sleep no matter your sleeping position. Magnetic headgear clips help guide the headgear to the frame and make putting on and taking off your mask a breeze.

Quick Release Elbow and Diffused Venting
The specially designed quick-release elbow on the AirFit™ F20 mask allows you to remove the tubing without having to take off the mask. Squeeze the sides of the quick-release elbow to detach it, along with your CPAP hose, from the mask.

When you return to bed, just push the quick-release elbow back into the front of your mask to reconnect it to your machine. Now you can get up during the night without having to worry about readjusting any straps when you get back in bed.

Multiple Headgear Sizes Available

The AirFit™ F20 is available in multiple sizes. A size gauge can be printed off and used as a guide to determine which size would be best suited for you.

This gauge is found on this webpage under the Size Gauge tab. It can be used to calibrate cushion sizes for the AirFit™ F20 mask. The cushion is available in Small, Medium, and Large. A Standard sized headgear comes with all three cushion sizes. Small and Large headgear sizes are available separately.

Interchangeable Cushions

Note: AirFit and AirTouch cushions of all sizes are compatible with the same F20 frame.

AirFit F20 Features:

  • Magnetic clips
  • Quick release elbow
  • InfinitySeal cushion
  • Adjustable headgear
  • Soft and flexible frame fits all size cushions

Disassembling and Reassembling the F20

Steps in disassembling the 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.

Steps in reassembling the F20 mask:

  1. Attach the cushion to the frame.
  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. Connect the elbow to the mask frame by pushing in until you hear a click.


How often should I replace the AirFit F20 mask?
In order for the mask to continue giving you the best sleep apnea therapy available, we recommend replacing the silicone cushion every 2 to 3 months. Replace the frame, elbow, and headgear every 6 months.

How should I clean my AirFit F20 mask?
Clean your mask regularly to control bacterial growth and prolong the life of the silicone cushion. Clean the cushion daily, and the frame, elbow, and headgear weekly. Handwash your mask parts with mild detergent and warm water. Air dry all parts out of direct sunlight.

How do I find out what mask size I need for the AirFit F20 mask?
The AirFit F20 has a size gauge available to make sure you find the best fit for you. Please print out the size gauge template you can access under the Size Gauge tab above.

I was long time user of the AirFit F10 full face, but I decided to upgrade to the F20 since it had some features I wanted to try. Immediately, I find the F20 to be a big upgrade and it’s a very good mask. It fits well and feels comfortable, and I have no complaints to speak of.

The big reason I wanted to upgrade from the F10 is that the F20 adds magnetic clips to the bottom two straps. I can’t stress how big of an addition this was, and how much easier it makes life. Probably the biggest part of getting great feel and performance from a mask is finding the perfect tightness on the straps. With the F10 however, you have to undo the bottom straps each morning, which means you’re changing the adjustment each time you take the mask off. Now, with magnetic clips, you just pull them off and your straps haven’t changed tightness at all. I’ve been getting consistent performance from this mask thanks to that, with no leakage issues to speak of.
Another big boon of the F20 over the F10 is that it’s a universal frame size now. The F10 had two different sizes I believe, which means you had to keep track of that alongside your cushion size. That’s no longer a problem.

Other than that huge addition, the F20 is very similar to the F10, which is a good thing. The headgear is still light and comfortable, holding onto my head well. No problems at all adjusting them to get an ideal fit. Cushion is still great too, it’s not quite the same as the F10 but it performs amazingly. The seal inflates well against my face and has no leakage issues. Just make sure not to tighten the mask too much, as you want the seal to fill in the gaps a little.

The hose still has the quick release elbow which is fantastic, since you can disconnect from your machine very quickly. It keeps the ring of vents too, so the air flow out is quiet and non-disruptive. Of course, as standard on the AirFit masks, there’s no bridge/forehead portion, which means you can wear glasses and have an unobstructed line of sight. Great for anyone like me who enjoys reading in bed.

The F20 is a great mask that takes all the best parts of the F10 and adds on some great convenience features. With the addition of the magnetic clips, I feel fully satisfied with this mask and I don’t imagine I’ll be changing masks any time soon. I would highly recommend to anyone on F10 looking to upgrade, or just to anyone looking for a great full face mask.

I heard really good things about AirFit masks from a friend, who used a nasal mask. However, I’m more of a mouth breather so I wanted a nasal mask and settled on the F20. So far, I can say it’s excellent in both build and performance.
The materials all feel very good, the straps on this one feel stronger than the straps I’ve had on past masks. On those masks, the straps would stretch out over time and fail to hold on to my head well. I don’t think I’ll have that problem with the F20 as the straps feel like they’ll hold their shape much longer.
Cushion material feels nice too, it’s nice and supple and seems to conform to the curves of my face quite well. Really solid seal and I haven’t had any problems with pain/red lines. It’s easy to disconnect the hose from the air feed which is always convenient and the design of the mask keeps my eye line mostly open.
If you’re looking for a good full-face mask with all the cutting edge features, I would recommend the F20.

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.

Hi I originally panned the F20 after one night of trying it out, but since then have found that, if adjusted properly, it is less likely to leak than any other mask I have tried, and I have many unused masks. I use a Bipap AVAPS machine and recently travelled overseas for a few weeks, taking both my F10 and F20, thinking that I would use the F10 mostly, but after a few days of travel realised that the F20 gives a better seal, is more comfortable and the straps are more reliable and less likely to rub. I have tried many masks including nasal masks, pillows and full face masks. As I suffer from COPD, lung caner and sinus problems I can only use a full face mask and this is the best I have found so far.

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.

I have tried many of the full-face masks available. I've not been happy with many of the masks I tried, probably because I sleep on my side - I think that makes it even harder to get a good mask seal. I really wanted to like the hybrid masks (under the nose style) but I couldn't get them to stop leaking. And of the masks that I could use, I find the AirFit F20 works best for me. The mask stays in place and seals very well. The hose attachment swivels effortlessly, and the air flow out of the mask is diffuse and silent. The cushion is easy to clean and replace, and I like the straps and fittings.

I work at a DME provider and with this mask the key is to not over tighten the headgear. Once you get a good seal adjust it then and let the cushion take over. If you can't run a finger between your headgear and your skin it's too tight and could cause leaks. Also make sure you are sized correctly. All masks run different. You may run a small in a Respironics but need a medium Resmed. I personally use this mask myself and have tried most mask just so I can tell my patients what to expect. This mask and the Amara View are my highest recommended for a full face mask.

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.

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.
