• cpap • By Krystle von Fange author portrait

Some CPAP users love the lightweight feel of nasal pillows, while others prefer the secure fit of a nasal mask. But the choice isn’t always simple—your sleep position, breathing habits, and CPAP pressure settings all play a role in determining the best option.

In this guide, we’ll break down the key differences between CPAP nasal pillows vs nasal masks, their pros and cons, and how MouthShield can help optimize your therapy by preventing air leaks and mouth breathing.

 👉 Looking for a way to stop mouth leaks and improve CPAP therapy? Check out MouthShield, a simple and comfortable way to help you breathe through your nose comfortably—and actually stick with your CPAP therapy.

CPAP Nasal Pillows vs Nasal Mask: Choosing the Right One

The basic difference between nasal pillows and nasal masks is that nasal pillows sit right at the entrance of your nostrils with a super lightweight, barely-there feel. Meanwhile, nasal masks cover the whole nose—they’re a little more secure and offer a bit more coverage.


There’s no one-size-fits-all answer here. What feels amazing to one person might drive someone else up the wall. So, let’s dig in a little deeper to figure out what’s better for your sleep style, comfort level, and pressure needs.


Feature

Small inserts rest at the nostril entrance

Covers the nose but not the mouth

Best for

Light sleepers, side/stomach sleepers, facial hair

People who need a secure fit

Breathing Style

Only for nasal breathers

Air Pressure Levels

Cons

Can irritate nostrils, may not seal well for some

💡 Takeaway: If you prefer a lightweight, minimal-contact option, nasal pillows might be best. If you need a more secure fit and higher pressure support, a nasal mask is the way to go.

Nasal Pillows vs Nasal Masks: Understanding How They Work

Both mask types do the same basic job—they deliver steady air pressure from your CPAP machine into your airway to keep things open while you sleep. But they do it a bit differently.

How Nasal Pillows Work

Nasal pillows are small cushions that sit directly at the entrance of your nostrils, delivering pressurized air from your CPAP machine. The fit is minimal, with less facial contact than other CPAP masks.

✔ Best for people who feel claustrophobic with larger masks.
✔ Ideal for side sleepers and those with facial hair (since there’s less material to interfere).
✔ Can reduce red marks or skin irritation caused by larger masks.

Downsides? They can be uncomfortable at high CPAP pressures and may cause nostril irritation over time.

How Nasal Masks Work

A nasal mask covers the nose, forming a seal around the nose bridge and upper lip. It delivers airflow through both nostrils without entering the mouth.

✔ More stable fit, making it ideal for those who toss and turn.
✔ Better for higher CPAP pressures, as the airflow is less direct.
✔ Less nostril irritation compared to nasal pillows.

The downside? It’s larger and can feel bulkier, especially for those who don’t like the feel of straps on their face.

Comfort, Fit, and Breathing: Key Differences Between Nasal Pillows and Nasal Masks

Your choice between CPAP nasal pillows vs nasal masks depends on several factors:

✅ Comfort & Fit

  • Nasal pillows are smaller, lighter, and less intrusive.

  • Nasal masks provide a more secure seal but have more facial contact.

  • If you move around a lot in your sleep, a nasal mask may stay in place better.

✅ Breathing Style

  • If you’re a nasal breather, both options work well.

  • If you breathe through your mouth at night, you’ll need a chin strap or Mouth Shield to prevent leaks.

✅ CPAP Pressure Tolerance

  • Nasal masks work better at higher pressures since the airflow is spread out more.

  • Nasal pillows can feel too intense at higher settings, sometimes leading to discomfort or dryness.

It’s easy to get caught up in the technical differences, but at the end of the day, what matters is this: does it help you sleep comfortably and breathe easily through the night?

For a lot of us, nasal pillows are a breath of fresh air—literally. They’re less bulky, less sweaty, and less intrusive. But if you toss, turn, or sleep with your mouth open, they can become a headache quickly. You might wake up with dry mouth, sore nostrils, or realize your mask has shifted off completely.

Nasal masks tend to stay put better and work great if you’re mostly a back sleeper. But they can feel a bit claustrophobic and may leave marks on your nose or cheeks.

Neither one is perfect, which is why having a little support system—like Mouth Shield—can really seal the deal (pun intended). It helps both styles work better by reducing mouth leaks and nudging your body into nasal breathing mode.

Solving the CPAP Problems No One Warned You About

CPAP Discomfort

If nasal pillows irritate your nostrils… try a larger size or use a CPAP humidifier.

If a nasal mask feels too tight… adjust the headgear or try a different cushion style.

Mouth Breathing & Air Leaks

Let’s be real for a second: CPAP therapy is a blessing—but it’s not always a breeze. If you’ve ever:

  • Woken up with air blasting out of your mouth

  • Pulled your mask off in your sleep without realizing

  • Struggled to fall asleep because of the pressure

  • Or given up on therapy altogether because it just didn’t feel right...

...you’re not alone. We’ve been there. And more often than not, the core problem is mouth breathing.

When your mouth falls open at night—even a little—it can wreck your therapy. Air leaks out, pressure levels drop, and the benefits of CPAP go out the window. That’s where MouthShield comes in.

So, What Is MouthShield—and Why Do We Keep Talking About It?

We’re glad you asked.


If you're using nasal pillows or a nasal mask, your mouth needs to stay closed for your therapy to work properly. MouthShield was built for exactly that.


MouthShield is something we created because we were tired of dealing with all the usual CPAP frustrations—dry mouth, air leaks, and waking up feeling like the therapy just wasn’t working. If you’ve tried chin straps, mouth tape, or gadgets that feel like medieval devices, you know what we mean.


MouthShield is different.


It’s a soft, flexible silicone insert that gently fits between your lips and teeth—not over your face. That’s it. No adhesives, no straps, no setup. You just pop it in before bed, and it helps keep your mouth naturally closed while you sleep. This way, you can breathe through your nose and avoid leaks or that dreaded morning dry mouth.


And yes, it’s trimmable so you can make it fit your mouth perfectly (because we all know “one-size-fits-all” rarely fits anyone). It stays in place all night long, even if you roll around, and doesn’t feel invasive or cause jaw tension.


It’s been a game-changer for us. And because it’s easy to customize and doesn’t interfere with your CPAP mask (whether you're using nasal pillows or a nasal mask), it fits seamlessly into your routine.


We tried all the other options—chin straps that felt like headgear, mouth tape that made us anxious, and bulky masks that never quite stayed put. MouthShield was the thing that finally made it all click. We didn’t build it to replace your CPAP—just to make it finally work the way it’s supposed to.

Making the Right Choice: Sleep Position, Breathing Habits, and Pressure Needs

Here’s the thing: there’s no gold medal winner between CPAP nasal pillows vs nasal mask. It’s about finding what feels right for you—and that might take a little trial and error.

Here are some quick tips based on our own experiences:

✔ Choose nasal pillows if:

  • You’re a side sleeper or want minimal facial contact.

  • You don’t need high CPAP pressure.

  • You don’t have frequent nasal congestion.

✔ Choose a nasal mask if:

  • You move a lot in your sleep.

  • You need higher CPAP pressures.

  • You prefer a more secure, traditional fit.

Choosing the Best CPAP Mask and Accessories for Effective Therapy

Finding the right CPAP mask is only half the battle—you also need the right accessories to make therapy work better.

✔ Mouth Shield prevents mouth leaks and promotes better nasal breathing.
✔ CPAP humidifiers help reduce dryness from pressurized air.
✔ Proper mask fitting ensures a secure, leak-free seal.

Final Thoughts: Try MouthShield For Better Sleep

Finding the right CPAP setup isn’t about choosing the “best” mask—it’s about choosing the one that helps you sleep peacefully, comfortably, and consistently. That might mean going with nasal pillows. It might mean a nasal mask. But for a lot of us, the missing piece was figuring out how to stop mouth leaks and actually breathe through our nose.

That’s what MouthShield was made for.

We designed it because we were frustrated too. We were tired of waking up exhausted, dealing with dry mouth, or wondering if CPAP was even doing anything. MouthShield changed that. And it can do the same for you.
