The Most Common CPAP Problems—and How to Fix Them

Why CPAP Problems Are Common (and Solvable)

Starting CPAP therapy can feel like a huge adjustment — you’re suddenly sleeping with air pressure, tubing, and a mask on your face. Almost every user experiences some frustration early on, but most issues have quick, simple solutions.

The goal of CPAP is to make you feel better, not burden you with discomfort. Here are the most common CPAP problems and what you can do to fix each one.

1. Mask Leaks

The problem:
Air leaking around your mask reduces pressure effectiveness and can cause noise or dry eyes.

Why it happens:

• Poor mask fit or wrong size 
• Facial hair or oily skin breaking the seal 
• Old or worn mask cushion

The fix:

• Try a different mask style — nasal pillow masks are great for minimal leaks. 
• Wash your face nightly to remove oils. 
• Replace mask cushions every 3–6 months for optimal sealing. 
• Adjust the straps while lying down with the machine running to find a natural sleeping fit.
  

💡 Pro tip: Over-tightening can make leaks worse by distorting the cushion. Aim for snug, not tight.

2. Dry Mouth or Throat

The problem:
Waking up parched or with a sore throat.

Why it happens:

• Mouth breathing with a nasal mask 
• Low room humidity 
• Insufficient humidifier settings
  

The fix:

• Switch to a full-face mask if you breathe through your mouth. 
• Add or increase your CPAP humidifier’s moisture setting. 
• Use a heated hose to keep airflow warm and prevent dryness. 
• Consider a chin strap to encourage nasal breathing. 

3. Nose Congestion or Irritation

The problem:
Stuffy nose, sneezing, or nasal irritation after using CPAP.

Why it happens:

• Dry air or allergies 
• Dirty filter or mask 
• Incorrect humidity level
  

The fix:

• Adjust your humidifier — often increasing humidity solves it. 
• Replace your air filter monthly. 
• Rinse your nose with a saline spray before bed to keep nasal passages open.
  

If symptoms persist, check for mask or detergent sensitivity and switch to hypoallergenic cleaning products.

4. Pressure Feels Too High or Too Low

The problem:
Feeling “blasted” by air or struggling to breathe against pressure.

Why it happens:

• Pressure setting not personalized 
• Ramp feature disabled or too short 
• Mask leaks altering pressure delivery
  

The fix:

• Enable the ramp feature — it starts at a lower pressure and gradually increases as you fall asleep. 
• Consult your sleep specialist about switching to an auto-adjusting CPAP (APAP) that fine-tunes pressure as you sleep. 
• Always fix leaks first; they can cause false pressure readings.

5. Difficulty Falling Asleep with the Mask

The problem:
You can’t relax or it feels awkward breathing with the mask.

Why it happens:

• Anxiety about the equipment 
• Unfamiliar noise or sensation 
• Poor mask comfort
  

The fix:

• Wear your mask for short periods during the day while reading or watching TV to desensitize yourself. 
• Try breathing exercises — focus on slow, even breaths through your nose. 
• Explore lighter, low-profile masks for less claustrophobia. 
• Add white noise in your room to mask machine sounds.
  

Remember: It often takes 1–2 weeks for your brain to adapt. Don’t give up too early — consistency is key.

6. Claustrophobia or Mask Anxiety

The problem:
Feeling trapped or panicky when the mask is on.

Why it happens:

• New users adjusting to sensation and sound 
• Mask style covers too much of the face
  

The fix:

• Start with nasal pillow masks or smaller cushion designs. 
• Practice wearing your mask for a few minutes with the machine off, then on. 
• Try relaxation techniques — gentle breathing or visualization before bed. 
• If anxiety persists, discuss it with your sleep doctor — small prescription changes or desensitization programs can help.

7. Noise and Disturbance

The problem:
The CPAP or mask makes noise that disturbs you or your partner.

Why it happens:

• Mask leaks 
• Obstructions in tubing 
• Old or malfunctioning machine
  

The fix:

• Check for leaks first — they’re the top culprit. 
• Ensure tubing isn’t kinked or pressed against furniture. 
• Replace aging machines (5+ years old) — newer ones are nearly silent (~25 dB).
  

Consider adding a CPAP hose holder to keep tubing stable and reduce noise.

8. Skin Irritation or Red Marks

The problem:
Redness, sores, or rash where the mask touches the skin.

Why it happens:

• Tight straps 
• Allergic reaction to mask material 
• Poor mask hygiene
  

The fix:

• Loosen the straps slightly and use mask liners for a soft barrier. 
• Wash mask cushions daily with mild, unscented soap. 
• Avoid alcohol or harsh cleaners — they break down silicone.
  

Rotate between mask styles or use moisture-barrier creams for sensitive areas.

9. Water in the Hose (“Rainout”)

The problem:
Condensation builds up inside tubing or sprays into your mask.

Why it happens:

• Cool room temperature vs. warm humid air 
• Humidity level too high
  

The fix:

• Use heated tubing or an insulating hose cover. 
• Lower your humidity setting slightly. 
• Keep your CPAP machine level with or below your bed height.

10. Mask Doesn’t Fit Right

The problem:
Discomfort, shifting during sleep, or leaks even after adjustments.

Why it happens:

• Wrong size or shape 
• Sleeping position misalignment
  

The fix:

• Get professionally fitted or use manufacturer sizing templates. 
• Try different styles — full face, nasal, or nasal pillow. 
• Consider a mask designed for your preferred sleep position (side, back, stomach). 

Final Thoughts

Every CPAP challenge has a solution — and once you find the right setup, therapy becomes second nature. The key is patience, consistency, and personalization.

If you’re struggling, don’t give up. Work with your equipment provider or sleep specialist to fine-tune your mask, humidity, and comfort features. The reward is worth it: deeper sleep, more energy, and a healthier life.
