ResMed CPAP Common Problems and How to Fix Them

Quick Answer

ResMed AirSense 10 and 11 devices share a common set of recurring problems that most users encounter within the first 2-3 years of nightly use. High mask leak warnings are the single most frequent complaint, followed by humidifier issues like water condensation in the tubing (rainout) and heating plate faults. Motor noise and the Motor Life Exceeded warning tend to appear after 3-4 years of heavy use.

Motor noise and the Motor Life Exceeded warning tend to appear after 3-4 years of heavy use. Most of these problems are fixable at home without tools - the exceptions are motor failure, screen failure, and internal heating circuit faults, which require DME provider service or warranty replacement.

Frequently Asked Questions

How often should I replace my ResMed CPAP supplies?
ResMed recommends replacing the mask cushion every 1-3 months, the full mask frame every 3-6 months, the disposable fine filter monthly, the hypoallergenic filter every 6 months, the tubing every 6-12 months, and the water chamber every 6-12 months. Insurance typically covers replacements on a similar schedule.
Why does my ResMed CPAP smell bad?
A musty or stale smell usually means the water chamber, tubing, or mask has bacteria or mold growth. Wash the water chamber and mask daily with warm soapy water. Replace the tubing if the smell persists after cleaning. Never reuse water left in the chamber from the previous night - always use fresh distilled water.
Can I travel with my ResMed CPAP?
Yes. The AirSense 10 and 11 have auto-switching power supplies that work on 100-240V, so they work internationally with just a plug adapter. The device does not count as carry-on luggage by TSA and airline policy. Empty and dry the water chamber before packing. Some users disable the humidifier entirely for short trips.
