Our review of the AirFit F40

ResMed's AirFit F40 is a compact full face mask made for people who breathe through both their mouth and don’t want to feel buried under bulky equipment. 

Its under-the-nose cushion and open-face design reduce facial contact, making it a good option for CPAP beginners who need face coverage.

Unlike many full face masks, the F40 also supports side sleeping without sacrificing seal quality, thanks to the AdaptiSeal cushion. Unlike some of the masks on this list, this one offers a triple swivel short tube, which creates a bit more room to move.

Another standout feature is the ultra-quiet design. The QuietAir vents dampen noise to just 20 decibels, making it the quietest CPAP mask on today's list.

Bottom Line: If you’re a mouth breather who wants the security of a full face mask with less weight and noise, the AirFit F40 delivers comfort without too much compromise.

Best Mouth Breather Mask for Side & Stomach Sleepers

ResMed AirFit™ F30i Full Face Mask

Pros

  • Slim front of mask is perfect for side or stomach sleeping

  • Top-hose connection eliminates tangling for active sleepers

  • Open line of sight for glasses and screens

  • Wide range of frame & cushion sizes to choose from

  • Offered in large frame and wide cushion

✗ Cons

  • Hollow frame may seem loud to some people

  • Hose connection is difficult to reach for people with arthritis

Our review of the AirFit F30i

The ResMed AirFit F30i is our top choice for CPAP users who sleep on their stomach or side. It combines full face coverage with the freedom of a top-of-head hose connection, which eliminates bulky tubing at the front of your face.

This mask is also good for people who toss and turn, as the 360-degree swivel elbow helps reduce hose drag and keeps your seal more secure throughout the night. 

Its under-the-nose cushion design also means less bulk on your face, fewer pressure points, and a clear line of sight for bedtime reading or TV.

The F30i is available in three different frame sizes and four cushion sizes, giving you more ways to get the perfect fit. These sizing options are especially helpful for people with larger heads or wider facial features.

Bottom Line: If you want a full face mask that stays sealed as you move and doesn’t get in your way when you change positions, the F30i is one of the most flexible options available.

Best Mouth Breather Mask for Active Sleepers

ResMed AirFit™ X30i Full Face Mask

Pros

  • Nasal pillows add security to your seal as you move

  • Top-of-head hose connection eliminates hose pulling & tangling

  • Ideal for restless or active sleepers

  • Minimizes bulk for side or stomach sleeping

  • Easy on and off magnetic clips

  • Magnetic clips save your fit settings

  • More stable than traditional nasal pillows

✗ Cons

  • Nasal pillows can cause sinus irritation

  • Magnetic clips not suitable for some implants

  • Hollow frame may seem loud to some people

  • Hose connection is difficult to reach for people with arthritis

  • Most expensive mask on our list

Our review of the AirFit X30i

The ResMed AirFit X30i is one of the most innovative full face masks available, offering the seal security of a full face mask with the low-profile feel of a nasal pillow.

Instead of sealing around your nose and mouth, this unique design uses a nasal pillow-style cushion for the nose combined with mouth coverage, making it more stable for people who shift positions frequently.

The top-of-head hose connection and 360° swivel elbow help reduce nighttime tugging and provide greater freedom to move. This design is especially helpful if you tend to roll from side to side or change positions while sleeping.

The minimal frame leaves your line of sight open, and magnetic clips make the mask easy to remove or reattach without adjusting your straps.

While this mask is more expensive than others and nasal pillows can sometimes cause sinus irritation, it's one of the best options out there for active CPAP users who need a full face seal that won’t budge when you toss and turn

Bottom Line: If you’re a mouth breather who moves around a lot at night, the X30i offers a secure, no-fuss seal that keeps up with your sleep style.

  • Can be leaky at high pressures

  • May irritate the base of the nose

  • Air venting not as quiet or gentle as other masks

  • Older design compared to newer mask models

  • More bulky compared to other under-nose masks

Our review of the Amara View

The Amara View Full Face Mask by Philips Respironics was one of the first under-nose masks on the market. Today, it delivers a popular design at more than half the price of other masks, like the AirFit F40. 

Its under-the-nose cushion helps eliminate pressure across the nose and opens up your line of sight, making it ideal for anyone who wears glasses or wants to unwind with a book or show before bed.

The headgear includes 5 adjustable straps, including a crown strap for a secure fit, plus magnetic clips for hassle-free removal.

Though it’s one of the more affordable full face masks on the market, it still delivers dependable therapy and a lighter, more open feel than many competitors.That said, some users report that it can leak at higher pressure settings or irritate the nostrils. 

Bottom Line: The Amara View's price point and comfort features make it a strong value—especially for mouth breathers who don’t want a mask that overwhelms their face.

Resmed AirTouch™ F20 Full Face Mask

Pros

  • Ultra-soft memory foam cushion is gentle on skin

  • Universal design fits 97% of people

  • No over-tightening needed to get a secure seal

  • Quiet design approved by light sleepers

  • Great for higher pressure settings

  • Magnetic headgear clips for easy removal

Our review of the AirTouch F20

Resmed's AirTouch F20 is the go-to full face mask for people with sensitive or easily irritated skin.

Its standout feature is the ultra-soft memory foam cushion, which gently sits against the face, creating a secure seal without overtightening your headgear.

Like the AirFit F20, the AirTouch version, this mask is a solid option for mouth breathers, especially those needing higher CPAP pressure.

The plush headgear is soft against your face, creating fewer red marks, while the magnetic clips make it easy to put on and take off.

Keep in mind that the memory foam cushion cannot be rinsed or soaked in water, and it requires more frequent replacement. Still, for many users, the tradeoff is worth it for the added comfort and reduced red marks.

Bottom Line: If traditional cushions leave your skin red or sore, the AirTouch F20’s soft memory foam is the most skin-friendly full face option out there.

Important features for CPAP masks for mouth breathers

Without the right equipment, people who breathe through their mouth during CPAP therapy often struggle with dry mouth, noisy air leaks, and poor treatment results. Choosing a full face or hybrid mask that seals both the nose and mouth is key. Look for these helpful features:

  • Soft, flexible cushions that adapt to your face shape

  • Slim under-the-nose full face designs that support side and stomach sleeping

  • Top hose connections that minimize bulk while allowing you to move freely

  • Adjustable headgear for a secure fit

  • Quiet venting for you and your partner

  • Fit packs with multiple cushion sizes so you can easily find your perect size

Choosing the best types of CPAP masks for mouth breathing

Under-the-Nose Full Face Masks: These compact masks seal under the nose and around the mouth, offering nose and mouth coverage with less bulk. These are ideal if you want something with minimal touchpoints. 

Traditional Full Face Masks: Great for high pressure settings or if you have thick facial hair. Covers both your nose and mouth for reliable therapy.

Hybrid Full Face Masks: These masks offer full face coverage, but seal inside the nostrils instead of around the nose, creating a secure seal that is less likely to leak air.

Top-of-Head Hose Connections: Eliminates bulk at the front of your face, so you can rest comfortably in any position without compromising your mask seal.

How to find a mouth breather CPAP mask for you

Start with your breathing style 

If you are unable to breathe through your nose while you sleep, a nasal or nasal pillow mask alone won’t work. Choose a full face or hybrid style to maintain your seal.

Consider your sleeping position

The next factor is how you sleep. Back sleepers can use any mask style, but side sleepers and stomach sleepers need something with a slim side profile that doesn't get pushed aside by your pillow. And active sleepers should choose a top-of-head hose connection for ultimate freedom. 

There are a range of sizing options

Full face masks usually come in three parts, including the headgear, frame, and cushion. Often times the headgear is one-size-fits-all all but the frames and cushions are offered in multiple sizes, including standard. So if you need a mask with extended sizing, keep that in mind. 

Keep in mind headgear adjustability

Almost all full face masks come with at least 4 adjustable pull tabs, usually with velcro. However, some masks, like those from Fisher & Paykel, feature an adjustable crown strap that allows for an even better fit. Masks like the Mirage Quattro even offer precision adjustments using a dial. 

Cushion design matters

Your cushion design is one of the most important parts because it's what creates your mask seal. Look for flexible cushions that fit the contours of your facial features and adapt to movement. If you have skin sensitivities, check out other cushion materials such as the memory foam AirTouch F20.

Tips for using CPAP as a mouth breather

Use a full face or hybrid full face mask

These mask styles seal your nose and mouth, so your CPAP air gets delivered to your airway, even with your mouth open.

Use a heated humidifier with heated tubing

Increasing your humidity levels prevents dry nosedry mouth, and sore throat by keeping moisture levels consistent, even if your environment changes. Heated tubing allows you to use Automatic Climate Control on your CPAP machine for even more control. 

Clean your CPAP mask regularly

Keep your CPAP mask clean by wiping it down daily and washing it weekly to avoid buildup that can affect your seal quality, cause air leaks, and lead to dryness and discomfort. 

Try a cushion liner to improve your seal

mask liner can add extra padding to reduce irriation and improve the seal quality between your cushion and your face. 

Frequently asked questions

Can mouth breathers use nasal pillows or nasal masks?

Yes and no. While you can't use a nasal pillow or nasal mask on its own, you can pair it with a chinstrap or an alternative treatment such as Somnifix to help keep your mouth closed during sleep.

Why do I wake up with a dry mouth even when using my CPAP?

Dry mouth is usually caused by air leaking from the mouth. A full face mask or improved mask fit can help.

What’s the difference between full face and hybrid masks?

Hybrid masks offer nose and mouth coverage but with a nasal pillow or nasal prong at the nose part. So unlike a full face mask that seals around the nose or nostrils, hybrid masks seal just inside the nostrils.

How often should I replace my full face CPAP mask?

The schedule for replacing your CPAP mask cushion depends on the cushion material, but generally speaking, your cushion should be replaced every 1–3 months, headgear every 6 months, and everything else every 6–12 months.

Final thoughts

If you breathe through your mouth at night, a full face CPAP mask is the best way to ensure comfortable, effective therapy. 

The best CPAP masks for mouth breathers offer a reliable seal, great fit, and minimal pressure points so you sleep better. Whether you choose a top performer like the AirFit F40 or an affordable option like the Amara View, your perfect mouth breather mask is out there.
