Keep your AirSense 11 humidification consistent and hygienic
Made for AirSense 11

This chamber is specifically designed for the AirSense 11. Your machine can even help you stay on schedule with the Humidifier Set function that provides replacement reminders. Browse other compatible components on the curated AirSense 11 Replacement Parts page or learn more about the device itself on the AirSense 11 AutoSet CPAP Machine page.

Care and cleaning, simplified

For best results, use roomโ€‘temperature distilled water only and avoid additives like oils or perfumes, which can affect materials and humidification output. Wipe the tub daily and dry it out of direct sunlight; wash weekly with warm water and mild detergent. The standard chamber is not dishwasher safeโ€”handโ€‘wash only.

  • Keep water below the marked max fill line.
  • Empty the tank before moving your device.
  • Rinse well and airโ€‘dry fully between uses.
Set up right, sleep right

Place your machine on a level surface below head height to help prevent water from reaching the mask or tubing. Do not power on without the tank installed; if youโ€™re not using water, keep the tank in place and set humidification to 0 to protect the motor and maintain proper airflow.

  • Avoid overfilling or tilting the device on its side.
  • Check for leaks or cracks and replace promptly if found.
