CPAP Cleaning & Maintenance Checklist

A clean machine isn't just more pleasant to use — it prevents mask leaks, skin irritation, odors, and premature equipment failure. Here's a routine that takes minutes a day.

Daily

• Wipe the mask cushion with a damp cloth or CPAP-safe wipe to remove facial oils.
• Empty any leftover water from the humidifier chamber (don't let it sit all day).

Weekly

• Wash the mask cushion, frame, and headgear in warm water with mild, unscented soap. Rinse thoroughly and air dry out of direct sunlight.
• Wash the humidifier water chamber the same way — check for any mineral buildup or discoloration.
• Wipe down the tubing exterior; if using non-heated tubing, an occasional interior rinse with warm water helps prevent buildup.
• Check the air filter and replace foam filters if visibly dirty or discolored.

Monthly

• Replace disposable filters on schedule (check your model's manual — commonly every 2–4 weeks).
• Inspect the mask cushion for signs of wear, stretching, or loss of shape — replace if the seal has degraded.
• Deep-clean tubing by soaking in a mild vinegar-water solution (1 part white vinegar to 3 parts water), then rinsing thoroughly and air-drying completely before reuse.

Every 3–6 months

• Replace tubing, cushions, and reusable filters per manufacturer guidelines — most insurance plans cover these replacements on a set schedule.
• Replace the humidifier water chamber if it shows any cracking, cloudiness, or persistent buildup.
