Picking the right CPAP mask matters more than most people expect. In fact, mask fit is one of the biggest reasons CPAP therapy either works well — or gets abandoned entirely. The machine does its job only if the mask seals properly and feels comfortable enough to wear every night.
If you're shopping for a CPAP mask in Canada, this guide covers every main mask type, who each style suits best, and what to look for before you buy. We focus primarily on ResMed masks here. If you're considering Fisher & Paykel or Respironics masks — including options compatible with the DreamStation 2 — look for those dedicated guides coming soon on PAPSmart.
The Three Main Types of CPAP Masks
Not all CPAP masks work the same way. Each style seals differently, fits differently, and suits a different kind of sleeper. Here's how they break down.
Full Face CPAP Masks
A full face mask covers both your nose and mouth. It creates a seal across the bridge of your nose, your cheeks, and under your lower lip.
Full face masks work best for:
- Mouth breathers
- People with nasal congestion or allergies
- Patients prescribed higher pressure settings
- Anyone who tends to open their mouth during sleep
The tradeoff is size. Full face masks are bulkier than other styles, which some side and stomach sleepers find uncomfortable. However, for anyone who can't breathe comfortably through their nose alone, they're often the only reliable option.
Popular option: The ResMed AirFit F20 is one of the most widely used full face masks in Canada. It offers a secure fit across a wide range of face shapes, with a magnetic clip system that makes removal easy.
Nasal CPAP Masks
A nasal CPAP mask covers only your nose — from the bridge down to just above your upper lip. It's a smaller, lighter option than a full face mask.
Nasal masks work best for:
- Nose breathers
- Active sleepers who move around at night
- Patients who find full face masks claustrophobic
- Those on moderate to high pressure settings
Because airflow enters through the nose, mouth breathing will break the seal and reduce therapy effectiveness. If you're unsure whether you breathe through your mouth at night, a nasal mask may need a chinstrap to work properly.
Nasal Pillow Masks
Nasal pillow masks are the most minimal option. Instead of covering your nose, two small cushioned inserts sit at the base of each nostril and deliver airflow directly.
Nasal pillow masks work best for:
- Claustrophobic users
- Glasses wearers who read or watch TV before bed
- Side sleepers who find larger masks disruptive
- People with facial hair that prevents a proper nasal mask seal
The limitation is pressure tolerance. At higher prescribed pressures, many users find nasal pillows uncomfortable. They're also not suitable for mouth breathers without a chinstrap.
How to Choose the Right CPAP Mask
With three main mask types available, the right choice comes down to four factors.
1. How do you breathe at night? If you're a confirmed mouth breather, start with a full face mask. If you breathe through your nose, a nasal mask or nasal pillow mask will likely be more comfortable.
2. What pressure is your machine set to? Higher pressure settings generally work better with nasal or full face masks. Nasal pillows can feel uncomfortable at higher pressures for some users.
3. How do you sleep? Side and stomach sleepers often prefer nasal pillow masks because there's less mask to get in the way. Back sleepers tend to tolerate any style.
4. Have you had fit issues before? Facial hair, a narrow nose bridge, or prominent cheekbones can all affect seal quality. In those cases, trying a different mask style — or a different cushion size — is worth it before giving up on therapy entirely.
Shopping for a Respironics or Fisher & Paykel mask?

CPAP Mask Cushions & Headgear Replacements
Even the best mask won't perform indefinitely. Over time, mask cushions lose their shape and seal less effectively. Most manufacturers recommend replacing cushions every one to three months, depending on use.
CPAP headgear stretches with regular wear as well. When headgear loses elasticity, users compensate by overtightening — which ironically worsens the seal and causes pressure marks on the face. Replacing headgear every six months keeps the fit where it should be.
Staying on top of mask parts is simple and inexpensive. It also makes a real difference to how comfortable and effective your therapy feels night to night.

Frequently Asked Questions
What is the most comfortable CPAP mask type?
Comfort is personal, but nasal pillow masks are generally rated most comfortable by users who can tolerate them. They're the least intrusive option for nose breathers at standard pressure settings.
Can I use any CPAP mask with my ResMed machine?
ResMed masks connect to ResMed machines using a standard 22mm fitting. Most ResMed masks are compatible with both the AirSense 10 and AirSense 11. Always confirm compatibility before purchasing.
Does PAPSmart carry Fisher & Paykel and Respironics masks?
Yes. PAPSmart is an authorized seller of both brands. Dedicated mask guides for Fisher & Paykel and Respironics — including masks compatible with the DreamStation 2 — are coming soon to the PAPSmart blog.
How often should I replace my CPAP mask cushion?
Every one to three months. If you notice air leaking around the seal or skin irritation from a hardening cushion, replace it sooner.
Does insurance cover CPAP masks in Canada?
Many private health plans in Canada cover CPAP masks and replacement parts with a valid prescription. Check your specific plan for coverage limits and approved suppliers.
What size CPAP mask do I need?
Most masks come in small, medium, and large. Manufacturers include sizing guides based on facial measurements. When in doubt, medium fits the widest range of face shapes.
