A Good Fit at a Glance
What a Suitable Starting Fit Should Support
- Comfortable contact with the face
- Stable positioning during normal movement
- A consistent seal without excessive tightening
- A style compatible with breathing and sleeping habits
Fitting options vary. Mask availability, sizing and trial options may differ by clinic, manufacturer and individual requirements.
Comfort and Therapy
Your Mask Is the Connection Between You and Your CPAP System
The mask delivers airflow from the machine through the nose, mouth or both. An unsuitable fit can contribute to leaks, movement, discomfort, dryness or difficulty continuing therapy.
Do not respond to mask discomfort by independently changing prescribed pressure settings. Contact the appropriate healthcare professional or MedPro team for support.
The Fitting Process
Your CPAP Mask Fitting at a Glance
The exact process may vary, but most fittings include several common steps.
01
Discuss Your Sleep and Breathing Habits
Talk about nasal or mouth breathing, sleeping position, movement, congestion, dryness, facial hair, glasses and comfort concerns.
02
Compare Mask Categories
Review full-face, nasal and nasal-pillow options based on your needs and equipment compatibility.
03
Determine an Appropriate Size
Use model-specific sizing guidance, facial measurements or trial fitting with available equipment.
04
Adjust the Mask and Headgear
Position the mask according to its instructions and secure the headgear without crushing the cushion against the face.
05
Check Comfort and Seal
Whenever practical, review the fit while lying in your usual sleeping position and with airflow operating.

Understanding the Main CPAP Mask Options
The right choice depends on breathing habits, sleeping position, comfort preferences and equipment compatibility.
Full-Face Masks
Cover the nose and mouth.
- May suit regular mouth breathing
- Can be considered when nasal-only therapy is difficult
- Provides broader facial coverage
- Seal should be checked during movement
Nasal Masks
Fit over the nose.
- Often chosen by people who mainly breathe through the nose
- Moderate facial coverage
- Available in many frame and cushion designs
- Mouth leak should be discussed
Nasal-Pillow Masks
Use small cushions positioned at or near the nostrils.
- Minimal facial contact
- Can work well with glasses or reading in bed
- Lower-profile design
- Nostril sensitivity and mouth breathing should be considered
Personalized Selection
The Best Mask Style Is Different for Everyone
Fit, comfort, breathing pattern and therapy compatibility should be considered together.
Breathing Habits
Do you usually breathe through your nose, mouth or both?
Sleeping Position
Side, back, stomach and active sleepers may experience different pressure points or tubing movement.
Facial Features
Face shape, nose shape, facial hair and dental structure may affect the seal.
Comfort Preferences
Some patients prefer minimal contact, while others feel more secure with greater coverage.
Vision and Bedtime Activities
Glasses, reading or watching television in bed may make a lower-profile design appealing.
Equipment Compatibility
Masks, tubing connections and machine features should be compatible with the prescribed system.
The smallest-looking mask is not automatically the best choice. Fit, comfort, breathing pattern and therapy compatibility should be considered together.
Fit and Seal
Secure Does Not Mean Extremely Tight
Headgear should be adjusted evenly and only enough to support the mask and seal. Tightening a leaking mask more and more can distort the cushion, increase pressure on the skin and sometimes worsen the leak.
Always follow the fitting instructions for your specific mask model because cushion placement and adjustment steps vary.
Signs of a Suitable Starting Fit
- The mask rests in the intended position
- The cushion is not visibly compressed
- Headgear feels secure rather than painful
- The mask does not shift with normal movement
- Airflow is not directed toward the eyes
- The seal remains reasonably stable while lying down
- The mask can be removed and reapplied correctly
A More Realistic Fit Check
A Mask Can Fit Differently When You Lie Down
Facial muscles and the position of the jaw can change when lying down and relaxing. A fit check in your usual sleeping position can reveal movement or leaks that are not obvious while sitting.
01
Put the mask on as demonstrated
02
Lie in your usual sleeping position
03
Start airflow using the instructed process
04
Check movement, comfort and obvious leaks
Do not block or cover the mask’s ventilation openings while checking for leaks.
Recognizing Fit Concerns
Contact MedPro When Problems Continue
Persistent leaks, pressure, irritation or difficulty keeping the mask on are signs that the fit should be reviewed.
Air Leaking Toward the Eyes
May indicate that cushion placement, sizing or headgear adjustment needs review.
Frequent Mask Movement
The mask may not match the sleeping position, frame size or movement pattern.
Pressure Marks or Pain
A secure mask should not require painful pressure or excessive strap tension.
Skin Irritation
Review cleaning, cushion condition, fit and skin-contact materials.
Dry Mouth or Nasal Dryness
Leaks, breathing habits, humidification or mask style may need to be considered.
Removing the Mask During Sleep
This may relate to comfort, leaks, dryness, claustrophobia or difficulty becoming accustomed to the mask.
Leak Troubleshooting
Why a CPAP Mask May Leak
A leak can result from fit, position, movement, cleaning or worn equipment—not only loose straps.
Fit and Position
- Cushion is not positioned correctly
- Mask size may not be suitable
- Headgear is uneven
- Headgear is too tight
- Mask shifts when changing position
- Tubing pulls against the mask
Equipment Condition and Care
- Cushion has accumulated facial oils
- Cushion or seal is worn
- Headgear has stretched
- Components are assembled incorrectly
- Mask parts are not fully dry
- A replacement component may be required
Do not assume that tighter straps will solve every leak. Repositioning the cushion or reviewing the mask size may be more appropriate.

Mask Fitting FAQ
Common Questions About CPAP Mask Fit
Contact MedPro when discomfort, leaks or irritation continue.
How tight should my CPAP mask be?
The headgear should feel secure, not painful. Tightening should be even and only enough to support the mask and seal without crushing the cushion.
Should a CPAP mask leave marks on my face?
Temporary light marks can occur, but persistent redness, pain or deep pressure marks should be reviewed. The mask may need repositioning, resizing or a different style.
Why does my mask leak when I lie down?
Facial muscles, jaw position, sleeping posture and pillow contact can change the seal. Recheck the fit while lying in your normal sleeping position.
Can I switch from a nasal mask to a full-face mask?
A different category may be appropriate when breathing habits, comfort or fit needs change. Confirm compatibility and sizing with MedPro or the appropriate healthcare professional.
What if I breathe through my mouth?
Discuss this during the fitting. A full-face mask or another solution may be considered depending on your prescribed therapy and individual needs.
Can facial hair affect the mask seal?
Yes. Facial hair can affect cushion contact and may require careful positioning, a different cushion design or another mask style.
Why does air leak toward my eyes?
This can happen when the cushion sits too high, the size is not suitable or the headgear is uneven. Reposition the mask and seek support if the leak continues.
What should I do if my mask causes skin irritation?
Check cleaning, cushion condition and fit. Stop using products not recommended for the equipment and contact MedPro when irritation persists.
How do I know whether I need a different size?
Ongoing leaks, movement, pressure or difficulty positioning the cushion may indicate a sizing issue. Model-specific sizing should be reviewed.
How often should mask parts be replaced?
Replacement timing depends on wear, manufacturer guidance, insurer requirements and individual use. Inspect parts regularly and replace them when worn or damaged.
