Cleanable Water Chamber for AirSense™ 11 Humidair™ Heated Humidifier

ResMed's Long Life Dishwasher Safe Humidifier Water Chamber is designed for use with the HumidAir Humidifier in all AirSense 11 series CPAP machines. Unlike the Standard chamber, this version can be fully disassembled and washed in the dishwasher or cleaned by hand.

Is This the Right Water Chamber for You?

This is the right choice if you'd rather run your water chamber through the dishwasher instead of hand-washing it every week. If you're comfortable hand-washing and want the standard, non-dishwasher-safe version instead, see the Standard Water Chamber for AirSense 11. Both fit the same AirSense 11 series machines — the choice comes down to cleaning method.

Standard vs. Cleanable: Which One Do You Need?

ResMed sells two versions of this chamber for the AirSense 11. This Cleanable chamber is dishwasher-safe and can be disassembled for a more thorough clean. The Standard chamber, sold separately, is designed for handwashing only. Both work with the same AirSense 11 series machines and provide the same heated humidification — this version simply gives you the option to run it through the dishwasher instead of washing by hand every week. See the Standard Water Chamber for AirSense 11 if you'd prefer that option.

Cleaning & Care

1. Disassemble the chamber weekly for cleaning.
2. Wash it in the dishwasher, or by hand with warm water and a mild detergent.
3. Dry it out completely, away from direct sunlight and heat, before reinstalling it in your machine.

Replace the chamber as needed, on average every 2 years, or sooner if you notice cracks, discoloration, or other wear. For complete instructions, review the documentation that came with your equipment.

Usage Notes

Drinking-quality water may be used with this chamber. A water chamber must always be installed in the AirSense 11 for the machine to work properly, unless a side cover is attached instead — useful to know if you ever need to run the machine without humidification, such as in Airplane Mode while traveling.
