The ResMed AirSense 10 AutoSet is one of the most common CPAP machines in Australia, and like the AirSense 11 it needs a few parts replaced on a regular schedule.

Filter: most people replace the standard filter every 30 days, or every 2 weeks if using the hypoallergenic version. A dusty or discoloured filter is the usual cause of a musty smell from the machine.

Humidifier tub: the water chamber is generally replaced every 6 months. Rinse it daily and check for cracking or cloudiness sooner if you notice reduced humidification.

Tubing and power supply: standard or heated ClimateLineAir tubing is usually replaced every 6 months. If your machine won't power on, check the power supply before assuming the machine itself has failed — it's a separate, replaceable part.

Every part here ships genuine, direct from ResMed's Australian supply chain, with free shipping on orders over $200 and same-day dispatch from our Adelaide warehouse.
