Step-by-Step care for your CPAP device

Regular cleaning of your Continuous Positive Airway Pressure (CPAP) device is key to achieving optimal results. Inevitably, the ambient humidity level and the air exhaled by the user lead to the formation of a microscopic layer composed of bacteria, fungi, and protozoa. Together, they form what is known as biofilm. This biofilm allows microorganisms to multiply within the mask and tubing of the device. The appearance and growth of biofilm increase the risk of respiratory tract contamination.

It is essential to thoroughly clean all parts of your CPAP device. However, remember that you should never use products such as alcohol, bleach, vinegar, or chlorine to clean your device. In addition, it is best to keep the CPAP machine near your bed, in a well-ventilated and dust-free area.

How to properly clean your CPAP device – Part by part

Humidifier

  • Cleaning frequency: Daily
  • Each evening before use, fill the water chamber with distilled or demineralized water up to the maximum fill line.
  • If limescale is visible in the humidifier, clean the deposits with a soft cloth and warm water. Then rinse the tank thoroughly with clean water.

Mask

  • Cleaning frequency: Weekly
  • Wash the mask with mild soap and lukewarm water. Rinse thoroughly with clean water.
  • Allow the mask to air dry in a cool, dry place.
  • Regular cleaning of the mask helps prevent skin irritation and reduces slipping caused by sebum buildup.

Tubing

  • Cleaning frequency: Weekly
  • Wash the tubing with mild soap, lukewarm water, and a non-abrasive sponge sized for the device’s tubing.
  • To ensure it is completely dry for the next use, clean it in the morning and hang it to air dry.

CPAP Filter

  • Cleaning frequency: Weekly
  • The filter’s role is to capture dust from the surrounding air.
  • Replace the filter as needed, and at least every 6 months.

CPAP Device

  • Cleaning frequency: Weekly
  • The exterior of the CPAP device must also be cleaned.
  • Wipe it down with a slightly damp cloth and a small amount of mild soap.
  • Dry with a clean, dry cloth.
