Overview
The ResMed AirFit F20 covers your nose and mouth with a silicone cushion that fills with air and shapes itself to your face, so it seals on light strap tension rather than a tight squeeze. That seal is designed to stay with you as you turn over.
Day to day, the frame sits low, under your eyes, so you can read in bed with it on, and the magnetic clips make the mask quick to take off and put back on. Its QuietAir vent softens the sound of each breath out.
Key features:
- Broad fit: In ResMed's own fitting studies, the AirFit F20 fit 97% of the existing CPAP users who tried it.
- Night-time breaks: Two buttons on the elbow free the hose, so you can get up during the night and leave the mask on.
- Works with AirMini: Pair it with ResMed's AirMini travel machine using the AirMini setup pack for F20 masks.
- Oxygen compatible: It works with supplemental oxygen when your prescriber adds it, through a standard connector your care provider fits.
- Made without latex: ResMed makes it without natural rubber latex, PVC, or phthalates, which is useful if you have a latex allergy.
- Licensed in Canada: Health Canada licenses the AirFit F20 as a Class II medical device, with the licence number listed under Specifications.
The AirFit F20 is ideal for mouth breathers, people living with allergies, and anyone who wakes up congested. If silicone irritates your skin, the AirTouch F20 fits a memory foam cushion to this frame, and the For Her version suits a smaller face.
Note: The frame and both lower clips hold magnets. If you have a pacemaker, defibrillator, or other implant that magnets can affect, or a bed partner or anyone else near you at night does, call us for a mask without magnets.
How it works
Putting the mask on
Unclip both magnets, then hold the cushion so its top edge lines up with the top of your nose bridge. Slide the straps back over your head with the ResMed logo facing out, bring the lower straps beneath your ears, and let each magnet find the frame.
Even out the upper straps first, then the lower ones, until the mask feels stable. With air flowing, lift the mask off your face for a moment so the cushion can fill and resettle. A leak near the top calls for the upper straps, and one near your chin for the lower pair.
Daily and weekly care
Each morning, separate the cushion, frame, and elbow, rinse them, then soak them in warm water mixed with a mild detergent, ten minutes at most, and shake them well. Brush around the vent holes and the frame joints, rinse again, and let everything dry in the air, out of direct sun.
Once a week, hand-wash the headgear the same way, leaving the magnetic clips attached. ResMed hasn't approved ozone or UV cleaners for this mask and warns that they can discolour or damage it.

Features and fit
Cushion comfort and support
ResMed varies the thickness and finish of the silicone around the cushion, adding support at the rim and softness where it meets your skin.
- Frosted silicone gives a softer touch around your nose
- Polished silicone along your mouth and jaw keeps the cushion from riding up
- Flexible side wings curve to follow your facial profile
- A soft nasal bridge, which ResMed designed to make red marks less likely
Padded under-the-eye frame
The frame is soft, flexible, and padded, so it adapts to many face shapes. Plush headgear holds it steady from the back of your head.
- A fabric lining on the frame adds softness where it touches you
- Long hair, even in a high ponytail, fits through the opening at the back
Clips and quick-release elbow
Magnets guide each lower strap to the frame, which ResMed notes is a real help if you have limited dexterity or low vision. The elbow is equally simple.
- Press its two side buttons to free the hose and get up without removing the mask
- It swivels a full 360 degrees as you change position
Machines and parts that fit
The AirFit F20 works with CPAP and bilevel machines from ResMed and other makers. On an AirSense or AirCurve, choose the Full Face mask setting.
- AirMini, with ResMed's AirMini setup pack for F20 masks
- Other brands: pick MIR FULL if the machine offers it, otherwise FULL FACE

InfinitySeal cushion
It holds its seal when you turn over, without cranking the straps tight. The silicone cushion fills with air and settles onto your face, and ResMed designed it to keep that seal at any pressure setting.
Under-the-eye frame
Your view stays clear for reading or watching TV in bed, because the padded frame sits below your eyes. ResMed designed it for people who find full face masks closed in.
Magnetic clips
Putting the mask back on takes seconds. The lower straps snap onto the frame with magnets and release with a twist, so your strap settings stay exactly where you left them.
QuietAir venting
Your exhaled air leaves quietly, so it's less likely to disturb you or the person sleeping next to you. The QuietAir vent spreads it out evenly, softening both the draft and the sound.
Common questions
When is it time for a new cushion and headgear?
ResMed suggests a new cushion every month, a new frame system every three months, and new headgear every six months. Replace any part sooner if you see cracks, tears, or other wear, as ResMed's user guide advises.
How do I find my AirFit F20 size?
Use ResMed's AirFit F20 fitting template, printed at full scale. It runs from the top of your nose bridge to just below your lower lip and shows which cushion size matches your face. Sizes from other masks may not carry over, so measure for this one.
What's different about the AirFit F20 For Her?
It's the same mask with smaller headgear, lavender accents instead of blue, and Small and Medium sizes only. It takes the same cushions as the standard Small and Medium, so replacement cushions are easy to find.
Is the AirFit F20 safe for someone with a pacemaker?
No. ResMed rules out magnetic masks when you, or someone in close contact with you while you wear one, such as a bed partner, has a pacemaker, defibrillator, neurostimulator, shunt, insulin pump, or a metal implant like an aneurysm clip or stent. Keep the magnets at least 150 mm from such devices. Call us for a mask without magnets.
Should I choose the AirFit F20 or the AirTouch F20?
Pick the AirFit F20 when you want a cushion you can wash each morning that holds its seal at high and low pressures. The AirTouch F20 shares the frame, headgear, and elbow, with a memory foam cushion ResMed designed to be gentler on skin. Both cushions are replaced monthly and fit either frame.
Do I need a prescription to buy this mask?
No. Masks don't need a prescription, so you can order this one straight away. We only ask for a prescription with CPAP machines and ventilators, before they ship.
