Using a dirty CPAP machine can cause respiratory symptoms, sinus issues, and skin irritation from breathing in mold, bacteria, and allergens.

Respiratory and Sinus Symptoms

  • Nasal congestion: A stuffy or blocked nose upon waking.
  • Runny nose or sneezing: Signs of irritation or allergic reactions to dust and mold inside the hose or filter.
  • Sore or scratchy throat: Irritation caused by uncleaned air passing through a dirty mask or tubing.
  • Coughing: Ongoing or dry coughs from airway irritation.
  • Sinus infections: Frequent sinus pressure, pain, or infections.
  • Morning headaches: Caused by restricted airflow from a dirty filter or sinus inflammation.
  • Severe infections: Higher risk of bronchitis or pneumonia if harmful pathogens or mold grow in the water chamber.

Skin and Face Symptoms

  • Skin irritation: Redness, itchiness, or soreness where the mask touches your face.
  • Breakouts and acne: Caused by oils, sweat, and bacteria building up on the mask cushion.
  • Skin rashes or dermatitis: Painful inflammation or rashes from neglected mask hygiene.

Warning Signs in the Equipment

  • Musty or moldy smell: A bad odor coming from the mask, hose, or water tank.
  • Visible buildup: Discolored filters or slimy residue in the water chamber.
