Using a CPAP machine is one of the most effective treatments for obstructive sleep apnoea — but for many patients, the real challenge isn’t the machine itself... it’s the mask. If your mask isn’t comfortable or doesn’t fit properly, you're less likely to stick with therapy. That’s why finding the right CPAP mask is one of the most important decisions you'll make for your sleep health.
In this guide, we break down the different types of CPAP masks, who they’re best for, and what to consider when choosing your perfect fit.
🛌 Why Mask Fit Matters
A well-fitted CPAP mask:
-
Prevents air leaks and ensures proper pressure delivery
-
Increases comfort for a better night’s sleep
-
Reduces the risk of skin irritation or pressure sores
-
Makes long-term therapy more successful
Poor fit, on the other hand, is the leading cause of discontinued CPAP use.
🧍 The Three Main Types of CPAP Masks
1. Nasal Masks
These cover only the nose and are ideal for:
-
People who breathe through their nose
-
Side sleepers
-
Users who want a lighter mask
Pros: Compact, less intrusive
Cons: Not suitable if you breathe through your mouth at night
2. Full Face Masks
These cover both the nose and mouth and are best for:
-
Mouth breathers
-
People with nasal congestion
-
Higher pressure settings
Pros: Great seal even with open-mouth breathing
Cons: Larger and can feel bulkier; may increase risk of leaks if not adjusted properly
3. Nasal Pillow Masks
These rest at the nostril entrance and are the most minimalist option. Best for:
-
Users who feel claustrophobic with larger masks
-
Those with facial hair
-
Active sleepers
Pros: Ultra-lightweight, open field of vision
Cons: Can cause nasal dryness or irritation for some
🔍 Key Factors to Consider When Choosing a Mask
✅ Your Breathing Style
Do you breathe through your nose or mouth while sleeping? Mouth breathers typically need a full face mask or a nasal mask with a chin strap.
✅ Your Sleep Position
-
Side sleepers: Nasal or nasal pillow masks are more suitable due to lower profile.
-
Back sleepers: All mask types can work, but full-face may feel more stable.
-
Stomach sleepers: Nasal pillows are the least obtrusive.
✅ Comfort and Seal
A proper seal prevents air leaks. Always test different cushion sizes and materials (silicone, memory foam, gel) to find what feels best.
✅ Pressure Settings
Higher pressure settings may require a more stable full face mask to avoid blowouts or leaks.
✅ Claustrophobia or Facial Hair
Claustrophobic patients usually prefer nasal pillows. Full face masks may not seal properly over facial hair.
