Millions of people around the world suffer from sleep apnea and one of the best ways to control the condition is to wear a CPAP machine. Continuous Positive Airway Pressure (CPAP) therapy also prevents your airway from collapsing during sleep and alleviates pauses in breathing, promoting better sleep. There are however, many people who have CPAP Machine Problems during the first few days of using a therapy or after extended use. Fortunately, many of these problems are easily solved.
If you are still new to CPAP therapy or have used the device for years, it’s important to know about the potential CPAP issues and how to resolve them to keep your sleep comfortable and uninterrupted. In this guide, we will be identifying the most frequent CPAP Machine Problems and how to solve them, as well as what causes these problems. In this guide, we will focus on the most common CPAP Machine Problems, what causes them, and how to solve them.
Understanding CPAP Therapy
A CPAP machine is a machine that pushes air through a mask during sleep to keep your airway from collapsing. It is often used to treat people with obstructive sleep apnea (OSA).
The system consists of typically:
- CPAP machine
- Air tubing
- Humidifier (optional or inbuilt)
- CPAP mask
- Filters
All components need to be maintained and used properly to ensure successful treatment.
1. CPAP Mask Leaks
One of the most common CPAP Machine Problems is CPAP mask leaks. If air leaks through the side of the mask, treatment is not as effective and it may disrupt sleep.
Causes
- Loose headgear.
- Incorrect mask size.
- Worn-out mask cushion.
- Sleeping position changes.
- Any facial hair that covers the seal.
Solutions
- Troubleshoot the mask straps making sure not to put too much strain on them.
- Change worn cushions at least twice a month.
- Choose the correct mask size.
- If necessary, use a different type of mask.
- Wash mask cushion every day to get rid of oils on the face.
Correct CPAP mask fitting is essential for optimal use of the machine and to avoid any leaks.
2. CPAP Dry Mouth
Many CPAP users complain about experiencing CPAP dry mouth, especially those who tend to breathe through their mouth during sleep.
Causes
- Mouth breathing.
- Low humidifier settings.
- Air leaks from the mouth.

Solutions
- Increase the humidifier level.
- If available, use a heated tube.
