Collection: AirSense 11 Replacement Parts

The ResMed AirSense 11 AutoSet needs a few genuine parts replaced on a regular schedule to keep therapy clean and effective.

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.

HumidAir 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: standard or heated ClimateLineAir tubing is usually replaced every 6 months — look for cracks, kinks that won't straighten, or a whistling leak.

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.
