How Much Water Does the ResMed AirSense™ 10 Humidifier Water Chamber Hold?

The ResMed AirSense™ 10 Humidifier Water Chamber has a water capacity of 380 mL, so you should never have to refill during the night. If you find that you run out of water in the middle of your therapy, humidification settings may need to be adjusted. These can be accessed through the “My Options” menu on your ResMed AirSense 10. If water remains in the chamber following a night of CPAP therapy, remove it and rinse the chamber thoroughly before refilling and beginning therapy again.
