Overview

The AirFit F20 is ResMed's full face mask for anyone who breathes through their mouth, deals with nasal congestion, or just can't hold a seal with a nasal mask overnight. It covers your nose and mouth with one InfinitySeal silicone cushion, so you're not fighting leaks every time you shift position or open your mouth. It's a solid pick if you're one of our mouth breathers looking for a mask built around that.

The frame sits under your eyes instead of across the bridge of your nose, so you keep a clear line of sight to read, watch TV, or wear glasses in bed. Magnetic clips on the lower headgear straps let you snap the mask on and pull it off in one motion, and the quick-release elbow disconnects from your hose without breaking your seal. It comes in Small, Medium, and Large, plus a For Her fit in Small and Medium with lavender accents, worth trying if the standard sizing runs big on you.

This is the silicone version of the F20. If you'd rather try a softer cushion, the AirTouch F20 uses the same frame and headgear with a memory foam cushion instead, so you can switch between the two whenever you want.

Like any CPAP mask, the AirFit F20 requires a prescription, and it's FSA/HSA eligible. Because the headgear uses magnetic clips, check the magnet safety FAQ below before you buy if you or anyone who sleeps near you has a pacemaker or another implanted medical device.

Important Tips

  • Check your cushion size before your first night. The InfinitySeal cushion should sit under your eyes and along your nose without gaps or pinch points.
  • Browse our full lineup of full face CPAP masks if you want to compare other brands and styles before you buy.
  • Adjust the headgear straps evenly on both sides. The mask should feel snug, not tight: overtightening causes leaks and red marks, not a better seal.
  • Attach the lower straps after you've placed the cushion on your face, then use the magnetic clips to snap the mask into position. The same clips make it easy to pull the mask off in the middle of the night.
  • If the standard fit runs big, try the AirFit F20 for Her or the AirTouch F20 for Her in Small and Medium sizes with lavender accents.
  • Side sleeping is fine with the F20. If you shift positions a lot, a CPAP-friendly pillow with cutouts for the mask and hose makes it easier to hold a seal.
  • If your mask is still leaking after checking the fit and cushion, our guide to reducing CPAP mask leaks covers the most common fixes.
  • Clean the mask daily with mild soap and warm water, paying extra attention to the cushion. Facial oils left on the silicone break down the seal faster.
  • Wash the headgear by hand about once a week and let it air dry completely. Machine washing and high heat wear out the elastic faster.
  • Inspect the cushion and frame for cracks, stiffness, or a cushion that's lost its shape. A worn cushion is the most common cause of a leak that won't go away.
  • Want a different feel? The AirTouch F20 memory foam cushion fits the same frame, so you can switch it in without buying a new mask.
  • If the vent or Anti-Asphyxia Valve is cracked or missing, replace the elbow rather than the whole mask. Don't use the mask with a damaged elbow.
  • Need other AirFit F20 parts? Shop cushions, frames, elbows, and headgear together in our CPAP mask parts collection.
  • Traveling with a ResMed AirMini? You'll need the F20 mask connector or the AirMini setup pack for F20 and F30 masks, plus a HumidX cartridge if you want humidification on the road.
  • If you notice marks or discomfort around your chin, the anti-leak strap is a comfort accessory made for the F20 and F30.
  • The headgear and frame contain magnets. Keep them at least 6 inches (150 mm) from a pacemaker or other implanted medical device, and see the magnet safety FAQ below for the full list of contraindications. If you need a magnet-free option instead, browse our full face masks without magnets collection.

Everything you need to know about the AirFit F20

One-Motion Magnetic Fit
Magnetic clips in the lower headgear guide the mask onto the frame and let you take it off in one motion, so there's no fumbling with straps if you wake up in the middle of the night.

Full Face Coverage for Mouth Breathers
The InfinitySeal silicone cushion seals over your nose and mouth in one cushion, so you keep your seal even if you breathe through your mouth, have a stuffy nose, or shift positions overnight.

Clear Sightline Under Your Eyes
The soft frame sits under your eyes instead of across your face, so you can read, watch TV, or wear glasses while you're on therapy.
ResMed AirFit F20 Full Face CPAP Mask

Compatible With Any CPAP or BiPAP Machine

The AirFit F20 works with CPAP and BiPAP machines from any manufacturer through a standard tubing connection. Just set the mask type to Full Face on your device (or MIR FULL if that's the option shown), and the quick-release elbow connects without extra adapters.

Find Your Size With the F20 Fitting Guide

Sizing is based on the cushion, and it doesn't carry over from other ResMed masks. Use the printable AirFit F20 fitting guide to measure your face before you order, and choose Standard Small, Medium, or Large, or For Her in Small or Medium with lavender accents.

Cushion and Headgear Replacement Schedule

Replace the InfinitySeal silicone cushion about once a month, since a worn cushion is the most common cause of a leak that won't go away. ResMed recommends replacing the frame about every 3 months and the headgear about every 6 months.

Complete Mask vs. Assembly Kit: What's Included

The Complete Mask includes the frame, InfinitySeal silicone cushion, quick-release elbow with a built-in vent and safety valve, and magnetic headgear, ready to use out of the box. The Assembly Kit is the same frame, cushion, and elbow without headgear, for anyone who already owns compatible F20 headgear.

Swap Between Silicone and Memory Foam Cushions

The AirFit F20 and AirTouch F20 share the same frame and headgear, so you can switch between this InfinitySeal silicone cushion and the AirTouch F20's memory foam cushion anytime. Silicone tends to hold its seal longer; memory foam feels softer against sensitive skin.

Quiet Enough for a Shared Bed

The QuietAir vent spreads your exhaled air out instead of releasing it in one noisy stream, so therapy is quieter for the person sleeping next to you.

Magnets in the Frame and Headgear

The frame and lower headgear clips contain magnets with a field strength up to 400 mT. Keep the mask at least 6 inches (150 mm) from a pacemaker, defibrillator, or other implant, for yourself and anyone who sleeps close enough to be affected. See our magnet safety FAQ for the full list.

Travel-Ready With Your ResMed AirMini

Pair the F20 with your ResMed AirMini using the F20 mask connector or the AirMini setup pack for F20 and F30 masks, since the standard F20 elbow doesn't attach directly. Add a HumidX cartridge for waterless humidification on the road.

FAQs

Do I need a prescription for the AirFit F20?

Yes. The AirFit F20 is a Class II medical device, so it requires a prescription from your doctor before you can buy it.

What's included with the AirFit F20?

The Complete Mask includes the frame, InfinitySeal silicone cushion, quick-release elbow with a built-in vent and Anti-Asphyxia Valve, and magnetic headgear. The Assembly Kit is the same frame, cushion, and elbow without headgear, for anyone who already owns compatible F20 headgear.

How do I choose between Standard and For Her sizing?

Standard comes in Small, Medium, and Large. For Her is the same mask in Small and Medium only, with lavender color accents. It is not a narrower cushion; the difference is the size range and color. Sizing is based on the cushion, and it doesn't carry over from other mask models, so size using the AirFit F20's own fitting guide.

Are the magnetic clips safe if I have a pacemaker or other implanted device?

No, not without talking to your doctor first. The frame and lower headgear clips contain magnets with a field strength of up to 400 mT, and the mask should be kept at least 6 inches (150 mm) away from active implants such as pacemakers, ICDs, neurostimulators, CSF shunts, and insulin or infusion pumps, and from metallic implants such as aneurysm clips, stents, valves, and cochlear or ocular implants. This distance applies to you and to anyone who sleeps close enough to be affected. If that describes you or a partner, talk to your doctor first, or browse our full face masks without magnets collection for a magnet-free alternative.

Will this mask work for a mouth breather or someone with a stuffy nose?

Yes. The AirFit F20 covers your nose and mouth in one cushion, so you keep a seal even if you breathe through your mouth or have nasal congestion that makes a nasal mask unreliable.

What's the difference between the AirFit F20 and the AirTouch F20?

The AirFit F20 and AirTouch F20 share the same frame and headgear; the only difference is the cushion. The AirFit F20 uses the InfinitySeal silicone cushion, which tends to hold its seal longer. The AirTouch F20 uses a memory foam cushion that feels softer against sensitive skin or facial hair, but wears faster and can't be washed. You can switch either cushion onto this same mask.

Can I use the AirTouch F20 memory foam cushion on this mask?

Yes. The AirFit F20 and AirTouch F20 share the same frame and headgear, so you can switch between the InfinitySeal silicone cushion and the AirTouch F20's memory foam cushion whenever you want a different feel.

How well does the F20 fit different face shapes?

In ResMed's fitting studies, the AirFit F20 fit 97% of participants across a range of facial profiles. The frame also sits under your eyes rather than across your face, which keeps your sightline clear for reading or watching TV.

Is the AirFit F20 compatible with my CPAP machine?

Yes. The AirFit F20 works with CPAP and BiPAP machines from any manufacturer through a standard CPAP tubing connection. On a ResMed AirSense, AirCurve, or S9, select "Full Face" as the mask setting; on other machines, choose "MIR FULL" if it's listed, or "FULL FACE" if not.

Can I use the AirFit F20 with a ResMed AirMini?

Yes, but you'll need the F20 mask connector or the AirMini setup pack for F20 and F30 masks, since the F20 doesn't attach to the AirMini directly. Add a HumidX cartridge if you want waterless humidification while you travel.

How often should I replace the cushion and headgear?

Replace the InfinitySeal silicone cushion about once a month, the frame about every 3 months, and the full headgear about every 6 months, or sooner if you notice cracking, loss of shape, or a cushion that won't hold a seal.

Is the AirFit F20 latex-free?

Yes. It's made without natural rubber latex and without PVC or phthalates such as DEHP, DBP, or BBP.

Is the AirFit F20 FSA/HSA eligible?

Yes. The AirFit F20 qualifies for FSA and HSA funds since it's a prescribed medical device.

Can I sleep on my side with the AirFit F20?

Yes. The soft frame and cushion move with you, though side sleepers sometimes find it easier to keep a seal with a CPAP-friendly pillow that has cutouts for the mask and hose.

What should I do if my AirFit F20 is leaking?

Start with the basics: check that you have the correct cushion size, make sure the cushion isn't worn or cracked, and reseat the mask by breaking the seal and gently pressing it back into place rather than pulling the straps tighter. Over-tightening is a common cause of leaks and red marks, not a fix for them. For more troubleshooting steps, see our guide to reducing CPAP mask leaks.
