ResMed AirSense 10 Dishwasher Safe Water Chamber

How often should I change the water in the humidifier tub? I never seem to use it all in one night.
The water should be changed daily, even if you don't use it all in one night.
What is the water chamber capacity ?
380 mL
Can the humidifier chamber really be washed in a dishwasher ?
The manufacturer states, "the humidifier may be washed in a dishwasher on the delicate or glassware cycle (top shelf only). It should not be washed at temperatures higher than 65 degree Celsius." The silicone seal cannot be placed in the dishwasher. Clean the seal with warm water and mild soap.
