How much water should my humidifier use overnight?

This will vary on a number of factors but on average an entire chamber of water will be used every 1-2 nights.

On average, people go through an entire chamber of water every 1-2 nights. However this may vary depending on a number of factors such as:

• Temperature/humidity of your bedroom
• Length of time your machine is being used for during the night
• Pressure settings of your machine
• Humidity level of your machine

If you find that the water in your humidifier is empty in the morning, then you can consider adjusting some of things mentioned above.

Don’t be surprised if the amount of water varies from night to night. It varies from one humidifier to the next, from one patient to the next, and with the temperature and humidity of the bedroom, as well as the settings of the humidifier itself.
