The ResMed AirFit F40 is the smallest full face mask ResMed makes, and it wears like it. Instead of stretching over the bridge of your nose, the AdaptiSeal silicone cushion seals just under your nostrils and over your mouth, so you keep a clear line of sight for reading, wearing glasses, or watching TV before you fall asleep.

We recommend it if you sleep on your side, breathe through your mouth some nights, or have felt boxed in by a bulkier full face mask before. The frame is a single flexible piece that moves with your face instead of fighting it, and the headgear clips on with magnets you can find and snap into place without turning on a light.

If you'd rather keep more coverage over your nose bridge, our AirFit F20 is the larger ResMed option built for higher pressures. Prefer your hose routed over the top of your head instead of in front of your face? The AirFit F30i does that. All three share the same family of cushion sizes, so switching between them later is straightforward. Browse the rest of our full face CPAP masks to compare. The AirFit F40 requires a prescription, and it's FSA/HSA eligible.

CPAP Mask Buying Guide

Adjust the headgear evenly on both sides until the mask feels snug, not tight. Overtightening will not improve the seal and can cause pressure marks.
Position the AdaptiSeal cushion just under your nostrils before you tighten the straps. It is designed to seal there, not up over the bridge of your nose.
The magnetic clips on the frame and lower headgear should snap together easily. Keep the mask's magnets at least 6 inches (150 mm) away from a pacemaker, defibrillator, or other implanted device. See our guide to CPAP masks for pacemaker and defibrillator patients if this applies to you or a bed partner.
Use the quick-release elbow to disconnect from your hose without pulling the whole mask off your face, useful for a quick trip out of bed.
If you notice leaks, reposition the mask before tightening the headgear further. Most leaks come from placement, not strap tension.
Clean the cushion and frame daily with warm water and a mild, fragrance-free soap to remove facial oils.
Use CPAP mask wipes for a fast clean when you do not have time for a full wash, especially while traveling.
Wash the headgear weekly by hand in warm, soapy water, then let it air dry away from direct sunlight to protect the elastic.
Let every part dry completely before you reassemble the mask, since trapped moisture can affect the seal and shorten the cushion's life.
Replace the AdaptiSeal cushion about once a month to keep the seal tight and hygienic.
Replace the headgear about every 6 months, since the fabric stretches with regular washing and use.
Check the cushion and frame for cracks, discoloration, or a loss of stretch, and swap out any part that is showing wear.
A UVC sanitizing device can give the mask, headgear, and tubing a deeper clean between hand washes.
Run a CPAP tube and mask brush set through the inside of your tubing regularly to clear out buildup.
Pack a spare cushion or a set of strap covers if you are traveling, since replacement parts are not always easy to find on the road.
Use the myAir app to check your mask fit and leak rate each morning, and adjust the headgear if the app flags a leak.

While this product includes the essential mask and headgear components, you'll still need to purchase a CPAP machine and hose to complete your therapy setup

FAQs

Everything you need to know about the AirFit F40

The AirFit F40 is ResMed's most compact full face design, so there is less mask on your face overall. That means a clearer sightline for reading or watching TV, and less bulk pressing against your pillow if you sleep on your side.

The AdaptiSeal silicone cushion seals just under your nostrils and over your mouth instead of stretching across the bridge of your nose, so you keep an open, unobstructed feel while it still holds a secure seal through the night.

The headgear snaps onto the frame with two magnetic clips instead of buckles, so putting the mask on or taking it off is a one-handed motion you can do without turning on a light.

Disconnect Without Taking the Mask Off

The AirFit F40 uses a quick-release elbow with a short tube, the only ResMed full face mask built this way. Pop the hose free for a quick trip out of bed, then click it back into place without touching your headgear.

Quiet Enough Not to Wake Your Partner

QuietAir venting is built into the elbow instead of scattered across the cushion, so exhaled air diffuses quietly away from your bed partner instead of blowing across the room.

One Frame That Flexes to Fit Your Face

The universal frame is a single flexible piece, so there's no separate frame size to match to your cushion. It moves with you instead of holding a rigid shape against your skin.

Gentle on Sensitive Skin

The AirFit F40 and its AdaptiSeal cushion are made without natural rubber latex, so it's a safer pick if latex sensitivity has been a problem with other masks.

Works With Nearly Any CPAP, APAP, or BiPAP Machine

The F40 connects with standard CPAP tubing, so it pairs with virtually any home CPAP, APAP, or BiPAP machine already using a standard hose, not just ResMed devices.

Bring It Along on an AirMini Trip

The AirFit F40 isn't a native AirMini mask, but it can connect for travel with an adapter and standard tubing. Confirm you have the right adapter before you pack it for a trip.

Silicone Comfort, No Memory-Foam Swap

The F40 uses ResMed's AdaptiSeal silicone cushion only, there's no AirTouch memory-foam version for this model. If you want that plush feel, our AirTouch F20 uses memory foam instead, and our AirTouch vs. AirFit comparison can help you decide.

Built for Side Sleepers Who Want a Low-Profile Fit

Less bulk sits against the side of your face and pillow than a traditional full face mask, which is why ResMed positions the F40 for side sleepers. See our picks for side sleepers for more options.

How to Use

Questions & answers

Is this comparable with the air mini / travel Cpap?: If your question is if the ResMed Airfit F40 is compatible with the Airmini, it is not really compatible but it can work. You just need to purchase these adapters and use a standard tubing https://sleeplay.com/products/snugell-airmini-hose-connector https://sleeplay.com/products/zephair-cpap-tubing-connector

FAQs

Yes. The AirFit F40 is a Class II medical device and requires a valid prescription, the same as any CPAP or BiPAP mask. We verify your prescription before your order ships.

The box includes the universal mask frame, the AdaptiSeal silicone cushion in your selected size, a quick-release elbow with a short tube, headgear, and two magnetic headgear clips.

The AdaptiSeal cushion seals just under your nostrils and over your mouth instead of stretching over the bridge of your nose. It still covers your nose and mouth airway as a full face mask, just with a smaller, more minimal-contact footprint than a traditional design.

The F40 is ResMed's smallest full face mask, with an under-nose AdaptiSeal cushion, a single flexible frame, and a short-tube quick-release elbow. The AirFit F20 is larger, covers over the nose bridge with an InfinitySeal cushion, uses a standard elbow, and can also swap to a memory-foam AirTouch cushion, which the F40 does not offer.

Both use an under-nose cushion, but the tubing routes differently. The F40 connects at the front with a short-tube quick-release elbow, while the F30i routes the tube over the top of your head. Choose based on whether you would rather keep the hose in front of you or out of your way overhead.

Yes, the AirFit F40 uses two magnetic headgear clips to connect the lower straps to the frame. Keep the mask's magnets at least 6 inches (150 mm) away from active medical implants such as pacemakers, defibrillators (ICDs), neurostimulators, CSF shunts, and insulin or infusion pumps, and from ferromagnetic metallic implants. If you or your bed partner has one of these devices, talk to your doctor before using this mask.

No. The AirFit F40 uses a 100% silicone AdaptiSeal cushion only; there is no AirTouch memory-foam version or cushion swap for this model. If you want a memory-foam full face option, the AirTouch F20 uses ResMed's UltraSoft memory foam cushion.

The cushion comes in Small Wide, Medium, and Large. Headgear comes in Small, Standard, and Large; the complete system ships with Standard headgear, and Medium cushions are also available paired with Small or Large headgear.

Not natively. The AirFit F40 connects with an adapter and standard tubing rather than AirMini's proprietary connector, so it can work for travel with the right adapter, but it is not a direct AirMini setup mask.

Yes. The mask and its cushion are made without natural rubber latex.

Yes. The AirFit F40 qualifies as an FSA/HSA eligible expense, so you can use pre-tax funds toward the cost.

The AirFit F40 connects with standard CPAP tubing, so it works with virtually any CPAP, APAP, or BiPAP machine that uses a standard hose connection.

As a general guide, replace the cushion about once a month and the headgear about every 6 months. Replace the full mask assembly about every 3 months if you are tracking an insurance replacement schedule, and replace any part sooner if you notice cracks, tears, or a loss of seal.

Yes. Its small, low-profile design and single flexible frame put less bulk against the side of your face and pillow than a traditional full face mask, which is why ResMed positions it for side sleepers.
