Choosing the right CPAP mask can make or break your therapy experience. The three most common mask types, full face, nasal, and nasal pillow each fit differently and are designed for different needs. At HelloSleep.ca, we help Canadians understand how each mask works so they can choose one that’s comfortable and effective for their therapy. This guide breaks down the key differences, how each mask fits, and how to decide which one is right for you.
Why Mask Type Matters
Your CPAP mask is where therapy meets comfort. The right mask should feel secure without being tight, reduce air leaks, and match how you naturally breathe during sleep. If your mask doesn’t fit well, you may experience:
- Air leaks and noise
- Dryness or irritation
- Poor sleep quality
If you’re already dealing with leaks or discomfort, check CPAP Mask Leaks and How to Fix Them for quick solutions.
Full Face Masks
Full face masks are the largest of them all and cover both the nose and mouth, creating a seal around both areas. The DreamWear Full Face is one of our best selling full face masks on HelloSleep.ca
Best for:
- Mouth breathers. Learn more in Mouth Breather? High Pressure User? Why Evora Deserves a Look.
- High pressure users
- People with nasal congestion
How they fit:
They should sit evenly around the nose and mouth without gaps. Because they cover more of the face, they can feel bulkier but offer a more secure seal for certain users.
Things to consider:
- More surface area can mean more points of contact
- May feel heavier than other options
- Ideal if you struggle to breathe through your nose at night

Nasal Masks
Nasal masks cover only the nose, either around it or beneath it in a cradle-style design and are among the most commonly used types of CPAP masks. The ResMed AirFit N20 Series is one of our best-selling nasal masks.
Best for:
- Nose breathers
- Users who want a balance of comfort and stability
- Moderate pressure settings
How they fit:
The cushion should seal gently around your nose without pressing too tightly. They are less bulky than full face masks but still provide a stable fit.
Things to consider:
- Not ideal for consistent mouth breathers
- Offers a good mix of comfort and performance

Nasal Pillow Masks
Nasal pillow masks use soft inserts that sit just inside the nostrils for a lightweight feel. A notable mention in this category is the AirFit P10 Nasal Pillow Mask. It is popular and well loved for many years in a row.
Best for:
- Users who want minimal contact
- Side sleepers
- Lower to moderate pressure settings
How they fit:
The pillows should sit snugly in the nostrils without causing discomfort. These masks are lightweight and often feel less intrusive.
Things to consider:
- May not be comfortable for very high pressures
- Requires a good seal at the nostrils

How to Choose the Right CPAP Mask
Choosing between these mask types depends on your sleep habits and comfort preferences.
Ask yourself:

What If None of These Masks Fit?
Most CPAP users find success with a full face, nasal, or nasal pillow mask. However, if you've tried multiple masks and continue to experience leaks, pressure points, or discomfort, a custom-made mask may be worth considering.
The FormFit Custom-Made CPAP Mask is individually manufactured from a 3D scan of your face, creating a personalized seal that's designed specifically for your facial contours. Rather than choosing from standard cushion sizes, the mask is custom built to improve comfort, reduce leaks, and provide a more consistent fit.
A custom mask may be a good option if you:
- Have tried several CPAP masks without success.
- Have unique facial features that make standard masks difficult to fit.
- Experience persistent leaks despite proper sizing and adjustments.
- Want a personalized solution after exhausting conventional options.
While custom masks aren't necessary for most CPAP users, they can be an excellent solution for people who haven't found success with traditional full face, nasal, or nasal pillow masks.

Comfort and Fit Tips
No matter which mask you choose, proper fit is key:
- Keep the mask snug, not tight
- Turn on your CPAP while adjusting
- Check for air leaks before sleeping
- Replace cushions regularly

Summary
Each CPAP mask type serves a different purpose. Full face masks offer coverage and stability, nasal masks provide balance, and nasal pillows deliver a lightweight, minimal fit. If you've tried several mask styles without finding a comfortable seal, a custom-made option such as the FormFit Custom Made CPAP Mask may be worth exploring. Choosing the right mask depends on how you breathe, sleep, and what feels most comfortable because the best mask is the one you’ll use every night.
