The right CPAP mask matches three things about you: how you breathe (through your nose or your mouth), how you sleep (on your side, back, or stomach), and what feels comfortable enough to wear every night. Get those three right, and therapy becomes much easier to stick with. Get them wrong, and you end up fighting leaks and red marks instead of sleeping.
Here's the short version before we help you narrow it down. If you breathe through your nose, a nasal or nasal pillow mask is usually the most comfortable choice and the least likely to leak. If you breathe through your mouth or run at high pressures, a full-face mask that seals over your nose and mouth is the safer choice.
Quick answer
- Breathe through your nose? Start with a nasal or nasal pillow mask, the most comfortable and least likely to leak (Journal of Sleep Research, 2022). [2]
- Breathe through your mouth, or run high pressure? Choose a full-face mask that seals over your nose and mouth.
- Not sure of your size? Use a fit pack or a printable fitting guide (both below) before you commit.

CPAP Mask Types at a Glance
Most people choose between three CPAP mask styles: nasal pillow, nasal, and full-face. But manufacturers like Fisher & Paykel also count a fourth oral category that seals only the mouth. [8] However, that differs from oral appliance therapy, a custom mouthpiece treatment that doesn't use CPAP. [9]
Here's how the three main styles compare, so you can spot your best starting point at a glance.
| Mask type | Where it seals | Best for | Watch out if | Example |
|---|---|---|---|---|
| Nasal pillow | At the nostrils | Side and stomach sleepers, claustrophobia, facial hair, glasses | You run very high pressure or breathe through your mouth | ResMed AirFit P10 |
| Nasal | Over the nose | Nose breathers who want a stable seal at most pressures | You are congested often or breathe through your mouth | F&P Solo, ResMed AirFit N30i |
| Full face | Over the nose and mouth | Mouth breathers, chronic congestion, higher pressures | You feel closed in by larger masks | ResMed AirFit F40, F&P Evora |
For a deep dive into how each style works, including hybrid and total-face options, see our companion guide on CPAP mask types.
How to Choose the Right Mask for You
Choosing the right CPAP mask comes down to four questions: how you breathe, how you sleep, what pressure you run, and what matters most for your comfort. Getting this decision right early pays off for the long haul of your sleep apnea treatment.
Mayo Clinic notes that getting the right fit, mask, and machine early on increases your chance of long-term success with CPAP therapy. [6] The American Academy of Sleep Medicine's treatment guideline also recommends education and hands-on troubleshooting support when you first start CPAP, which is when the right mask makes the biggest difference. [1] Work through the four questions below in order.
"Different preferences, sleeping positions, anatomy, and lifestyle all affect the mask type that works best for you."
— Teresa, Clinical Sleep Coach, Sleeplay
1. Do you breathe through your nose or your mouth?
Your breathing route is the single most important question. If you breathe through your nose, start with a nasal or nasal pillow mask.
The evidence favors them. A 2022 network meta-analysis in the Journal of Sleep Research found that nasal masks and nasal pillows are better interfaces than full-face (oronasal) masks. [2] A randomized trial published in the Journal of Clinical Sleep Medicine also reported fewer leak and fit problems with nasal masks. [3]
If you breathe through your mouth, a full-face mask is the answer. Mayo Clinic recommends one when you still breathe through your mouth at night after trying a nasal mask. [6] For nose breathers whose jaws tend to fall open during sleep, a CPAP chin strap can help keep the mouth closed so the nasal mask keeps working.
2. What position do you sleep in?
Side and stomach sleepers: Choose a low-profile mask that won't get knocked out of place by the pillow. Nasal pillow masks, such as the ResMed AirFit P10, work well here. Top-of-head tube designs like the ResMed AirFit N30i and AirFit P30i work well too, moving with you and keeping the hose out of the way.
Back sleepers: You have the widest choice. Nasal, nasal pillow, and full face masks all seal well when you sleep on your back.
3. What pressure do you run?
Your pressure setting matters because higher pressures push harder against the seal. Full-face masks like the ResMed AirFit F30i or AirFit F40 tend to maintain a stable seal at higher settings. Nasal pillow masks like the AirFit P10 shine at lower pressures.
Not sure of your pressure? Your prescription lists it. Our guide on how to tell if your CPAP pressure is too high also explains the warning signs and what to do about them.
4. What matters most for your comfort?
Sensitive skin, a beard, or the desire for a wide field of vision for reading all point toward minimal-contact designs. Nasal pillow masks touch the least skin. Memory-foam cushions, like the one on the ResMed AirTouch N20, mold to your face and work well if you're prone to irritation.
You'll find more comfort-first picks in our roundup of the top 5 most comfortable CPAP masks.
Best CPAP Mask by Situation
The best CPAP mask for you depends on the specific challenge you're trying to solve, whether that's side sleeping, mouth breathing, a beard, or feeling closed in. Find your situation below and start with the mask named for it. Each one is a real recommendation, not a spec list.
How we picked these: These are the masks our CPAP specialists reach for most when a customer describes their situation. Our picks come from hands-on fitting experience, what customers keep after our mask exchange program, and manufacturer fit specs. We sell every mask here, and we still tell people the smallest mask that solves their problem is usually the best first choice.
Best for side sleepers
The best CPAP masks for side sleepers hold their seal when your cheek presses into the pillow. The AirFit N30i and AirFit P30i route the tube over the top of your head, so you can roll freely. For nose breathers, the F&P Solo sits light and low on the face.
Your pillow plays a part too. A CPAP pillow with cutouts keeps the mask from shifting when you turn onto your side.
"You need a mask that stays put even when you don't. Adjustable headgear gives you a snug, custom fit that won't shift when you change positions."
— Daniel Feldman, CPAP Expert, Sleeplay
Best for back sleepers
Back sleepers can wear almost any style. Nasal, nasal pillow, and full-face masks all seal well against your face, so choose based on your breathing route and what feels most comfortable.
Best for stomach sleepers
Stomach sleepers do best with the lowest-profile option. A slim nasal pillow mask like the AirFit P10 or a top-of-head design keeps bulk off the pillow and away from your face.
Best for mouth breathers
The best CPAP mask for mouth breathers is a full face mask. It covers your nose and mouth, so therapy keeps working even if your jaw drops open during sleep. The AirFit F40, F&P Evora Full Face, and AirFit F20 are all strong, well-sealing options.
Best for facial hair and beards
Facial hair makes it harder for most cushions to seal, since they're designed to sit on flat, smooth skin. Nasal pillow masks like the AirFit P10 seal inside the nostrils instead, so a beard interferes far less.
Best for claustrophobia (and the smallest footprint)
The best CPAP mask for claustrophobia is the smallest one that still treats your sleep apnea. The AirFit P10 nasal pillow mask keeps your field of vision open and touches very little of your face.
This matters more than it might seem. Feeling boxed in is a documented reason people abandon CPAP therapy, so easing in with a minimal mask gives you a better chance of sticking with it. [5]
"If you are claustrophobic, you will not use your machine. You will be so nervous you won't be able to relax enough to go to sleep. That is understandable, and there are other options."
— Lilly Perez, Respiratory Therapist, Sleeplay
Best if you wear glasses or read in bed
If you wear glasses or like to read or watch TV in bed, look for a top-of-head tube mask that doesn't contact the bridge of your nose. The AirFit P30i and AirFit N30i both leave room for glasses and give you a clear line of sight.
Best for higher pressures
Higher-pressure settings require a full-face mask that can maintain a steady seal. The AirFit F30i and AirFit F40 both perform well at higher pressures. If you're not sure of your setting, check your prescription or read through our CPAP pressure guide.
Best for restless movers
If you toss and turn, top-of-head tube designs like the N30i, P30i, and F30i let the hose follow you instead of tugging on the cushion.
Best for sensitive skin
The best CPAP mask for sensitive skin minimizes contact or uses a softer cushion. Minimal-contact pillow masks touch the least skin. Memory-foam cushions like the AirTouch N20 mold to your face and ease pressure points.
If your skin still reacts, soft mask liners add a gentle barrier between the cushion and your face.
Signs You Picked the Wrong Mask
The most common signs of the wrong CPAP mask are air leaking near your eyes, red marks, a dry mouth, feeling closed in, and loud air noise. A few bumps are normal when you start. Most of them are a signal to adjust, not to give up.
If any of these sound familiar, the table below shows the likely cause and the first thing to try.
"Most mask problems happen for one reason. People try to solve discomfort by tightening the mask, and that almost always makes things worse. A good seal comes from fit and positioning, not pressure."
— Lilly Perez, Respiratory Therapist, Sleeplay
| What you feel | Likely cause | What to try first |
|---|---|---|
| Air leaking near the eyes | Cushion too big, or headgear over-tightened | Refit with a sizing guide, loosen slightly, then re-seat the cushion |
| Red marks or sore spots | Straps too tight or wrong cushion size | Loosen the headgear (over-tightening causes leaks and marks), refit, or add strap covers |
| Dry mouth in the morning | Mouth is opening on a nasal mask | Add a chin strap, or switch to a full face mask |
| Feeling closed in | Mask footprint is larger than you need | Move to a nasal pillow mask like the AirFit P10 |
| Loud air noise | Leak at the seal, or a dirty vent | Re-seat the cushion, clean the vents, replace a worn cushion |
Most fit problems are fixable, and they're a signal to adjust, not to quit. In our experience, the fix is usually the mask, the humidification, or the pressure.
Research backs this up. A 2019 review of CPAP adherence studies in the journal Lung lists the mask interface as one factor that shapes whether people stay on therapy. That makes the wrong mask a common, and very fixable, reason people struggle with CPAP. [4]
How to Choose the Correct Size
To choose the correct CPAP mask size, measure your face with a printable fitting guide or try a fit pack that includes several cushion sizes. Getting the size right matters as much as getting the style right.
An ill-fitting mask leaks, marks your skin, and weakens your therapy. As Mayo Clinic puts it plainly, air leaks happen when the mask does not fit correctly. [7]
Even the right mask needs a proper first fit. Put it on while lying down in your sleep position, then turn the machine on. Tighten the straps only until the leak stops, and no further. Over-tightening is the most common fit mistake we see.
"When you're trying to fit a CPAP mask, you're looking for three things. First, adequate therapy. Second, that the mask is comfortable enough to use. Third, that it is the proper size so it seals properly."
— Oswald (Ozzy) Azua, Respiratory Therapist, Sleeplay
Watch Ozzy demonstrate the process step by step in the video below:
CPAP mask sizing guide
These are the masks customers ask us to size most often, across all three styles. Each row links to the printable size guide we host for that mask, or to the size selector on the product page. If you're between sizes, a fit pack lets you try more than one.
Fit packs and replacement parts
Fit packs: Still unsure of your size? A CPAP mask fit pack includes several cushion sizes in one box, so you can keep the one that seals best. The AirFit P10, F&P Solo, and Swift FX all come this way.
Keep it, don't rebuy it: Once you find your fit, you can maintain the mask with replacement cushions, headgear, and frames instead of buying a whole new mask.
Will This Mask Fit My Machine?
Almost every CPAP mask will fit your CPAP machine or CPAP device. It's one of the most common questions we get, and the answer is reassuring.
Almost always yes: Nearly every CPAP mask fits nearly every CPAP machine because they share a standard tube connection. The mask sets your comfort and seal, and the machine sets your pressurized air.
Popular machines are covered: Any mask in this guide works with the ResMed AirSense 11 and the AirSense 10. It also works with the AirMini travel CPAP unit, which uses a small mask-specific adapter sold with its setup packs.
When to double-check: An unusual setup or a very high prescribed pressure is worth a second look. When in doubt, ask your provider or us.
So if you're looking for the best mask for your AirSense 11, use the same rules as any other machine: breathing route first, then sleep position and comfort. Shopping for a new machine too, such as an auto CPAP? Our AirSense 11 bundles pair the machine with the mask you choose.
Common Mask Problems and Quick Fixes
Most common CPAP mask problems and side effects, like a dry nose, congestion, or sore spots, have a quick fix or the right accessory. Here are the ones we see most.
Dry nose: Add a heated humidifier to add moisture to the air and prevent dryness.
Congestion: Try a saline spray at bedtime, or switch to a full-face mask like the AirFit F40.
Claustrophobia: Switch to a nasal pillow mask, such as the AirFit P10.
Red marks or sore spots: If a refit doesn't solve it, add soft strap covers or a mask liner as a barrier between the mask and your skin.
Trouble exhaling against pressure: Ask your provider about pressure relief settings.
Replacing worn parts: A cushion that won't hold its seal is worn out, not broken. We generally recommend swapping the cushion every few weeks and the mask every 6 to 12 months.
When an issue goes beyond the mask itself, our full playbook on common CPAP problems and their fixes walks you through the next steps.
Choosing with Confidence: Returns, FSA/HSA, and Prescriptions
Buying a CPAP mask is low-risk once you understand exchanges, FSA/HSA payments, and prescriptions. Picking a mask you've never worn can feel like a gamble, so we make it low-stakes. Here's how the buying side works.
Mask exchange: If your first choice doesn't work out, our mask exchange program lets you swap it for a different size or style. You can find all the details in our mask exchange policy.
FSA and HSA: CPAP masks are FSA- and HSA-eligible, so you can usually pay with pre-tax dollars.
Prescriptions: Under FDA rules, a mask is a prescription item, just like your machine. If you already have a CPAP prescription, it covers your mask too. New to prescriptions? Our guide on buying a CPAP without a prescription explains what you'll need.
The Bottom Line
If you remember three things, remember these.
Breathing comes first: Start with how you breathe, then match your sleep position, pressure, and comfort. Nose breathers do best with a nasal or pillow mask, and mouth breathers need a full face mask.
Size matters: Get the size right with a printable fitting guide or a fit pack, and lean on our exchange program if the first pick isn't perfect.
Adjust before you quit: If CPAP still feels hard, in our experience the answer is usually the mask, the humidity, or the pressure, not quitting.

FAQs
How do I know which CPAP mask is right for me?
Match the mask to how you breathe, how you sleep, and your prescribed pressure. Nose breathers typically do best with a nasal or nasal pillow mask. Mouth breathers need a full face mask that covers both the nose and mouth. Side sleepers benefit from low-profile designs or masks with a top-of-head tube connection that stay in place when you roll over.
What is the most commonly used CPAP mask?
Nasal and nasal pillow masks are the most widely used because they are compact, comfortable, and seal well for the majority of CPAP users who breathe through their nose. Full face masks are the standard choice for mouth breathers.
Which CPAP mask is least likely to leak?
A correctly sized mask that matches your breathing pattern leaks the least. Research shows nasal masks tend to have fewer leak and fit problems than full face masks. Most leaks are caused by the wrong cushion size or headgear that has been overtightened to compensate for a poor fit.
What is the easiest CPAP mask to get used to?
Many first-time users find nasal pillow masks easiest to adapt to because they have the smallest footprint, keep your field of vision open, and are much less likely to trigger feelings of claustrophobia. The ResMed AirFit P10 is a common starting point for new users for exactly these reasons.
Which CPAP mask is best for mouth breathers?
A full face mask that covers both the nose and mouth is the right choice for mouth breathers, so therapy remains effective if your jaw drops open during sleep. Commonly recommended options include the ResMed AirFit F40, the Fisher and Paykel Evora Full Face, and the ResMed AirFit F20.
How often should I replace my CPAP mask?
The cushion or pillow inserts should be replaced every few weeks to once a month. The full mask frame and headgear should be replaced roughly every six months to a year. Replace sooner if the cushion can no longer hold a seal, or if the silicone feels sticky, stiff, or visibly worn.
Can I use any CPAP mask with my CPAP machine?
In almost all cases, yes. Nearly all CPAP masks are compatible with nearly all CPAP machines. The mask provides the seal and comfort interface while the machine provides the pressurized air. If you have an unusual setup or a specialized device, confirm compatibility with your equipment provider.
What is the best CPAP mask for side sleepers?
Side sleepers do best with a low-profile mask that stays in place when the face contacts a pillow. Top-of-head tube designs such as the ResMed AirFit N30i and AirFit P30i allow you to roll freely without dislodging the mask. A slim nasal pillow mask like the AirFit P10 is another strong option. Using a CPAP pillow with cutouts at the sides can also help any mask stay sealed while side sleeping.
What is the smallest CPAP mask?
Nasal pillow masks have the smallest footprint because they seal at the nostrils rather than over the nose or face. The ResMed AirFit P10 is one of the most minimal designs available and is a common first choice for people who feel closed in or uncomfortable with larger masks.
Which CPAP mask brands does Sleeplay carry, and how do I choose between them?
We carry ResMed, Fisher and Paykel, and Philips Respironics, the three brands that account for most prescribed masks. The best approach is to choose by fit and feel rather than brand. Start by identifying your mask type based on how you breathe: nasal pillow, nasal, or full face. Then compare specific models within that type for size range, cushion material, and comfort features.
