Before You Start

Step-By-Step: How To Clean A ResMed AirSense 10 Water Chamber

Disassemble the humidifier: detach the water chamber from the main unit and remove any removable parts per the user manual.
Rinse with lukewarm water: gently rinse the chamber to remove loose dust and saliva residue.
Soapy wash: add a small amount of mild, fragrance-free soap and scrub the interior with the CPAP water chamber cleaning brush for ResMed or the long-reach brush to reach all corners.
Rinse thoroughly: ensure all soap bubbles are gone, as soap residue can irritate users during therapy.
Address mineral buildup: for hard water deposits, use CPAP humidifier chamber cleaning tablets for Water Chamber as directed by the tablet instructions.
Final rinse and dry: rinse again until completely clear, then pat dry with a clean towel and air dry the chamber away from direct sunlight.
Inspect for wear: check the seal, gaskets, and the chamber for cracks or discoloration. If any damage is found, consider a ResMed water chamber replacement kit.
Reassemble and test: once fully dry, reattach the chamber to the unit, fill with fresh water, and run a brief humidification test to ensure proper function.
Store properly: when not in use, keep the chamber in a clean, dry location to prevent contamination.
Follow a schedule: set a recurring reminder to clean weekly, or more often if you live in a hard-water area.
Supplemental care: consider using distilled water daily to minimize mineral buildup and extend the interval between deep cleanings.
