Many people use positive airway pressure (PAP) therapy to support their breathing. PAP therapy can help with conditions like obstructive sleep apnoea, respiratory muscle disorders, or lung conditions like Chronic Obstructive Pulmonary Disease (COPD) and Cystic Fibrosis (CF).

Some machines provide a steady flow of air to keep airways open (CPAP), while others give an extra boost when you breathe in (Ventilators). Whatever type of machine you use, here are some easy tips to help keep your equipment clean, safe, and in good working condition.

Note: always check and follow equipment manufacturer’s recommendations

1. Caring for masks, straps and tubing

  • Clean weekly: Separate the mask, straps, and tubing, and disconnect the tubing from the machine and humidifier. Wash with mild soapy water, rinse well, and let air dry. Hanging tubing over a rail helps it dry completely.
  • Avoid damage: Use lukewarm water and gentle soap. Avoid hot water, harsh cleaners, or drying in direct sunlight, which can damage the plastic and elastic.

2. Looking after the humidifier

If your machine has a humidifier, it helps keep the air moist and more comfortable to breathe. To keep it in top shape:

  • Daily care: Every morning, empty and rinse the chamber, then leave it to dry. Before bedtime, refill it with fresh demineralised or distilled water to avoid mineral buildup over time.
  • Weekly cleaning: Clean the chamber thoroughly with warm, soapy water. Rinse and air dry.
  • Monthly deep clean: Soak the chamber in a diluted solution of white vinegar (1 part vinegar to 10 parts water) to remove any lingering deposits.

3. Checking filters

  • Regular checks: Clean the filter area with a damp cloth to remove dust. Some filters can be washed, but disposable filters should be replaced every six months or sooner if they look dirty.

4. Maintaining the machine

  • Routine checks: PAP machines are designed to last, but they may need maintenance as they age. Manufacturers usually recommend a check-up after five years, or sooner if you notice unusual noises or other changes. Report any issues to your supplier promptly.
