Do I need a Humidifier?
A humidifier adds moisture to the airflow coming from the CPAP machine.
Using a humidifier can help to reduce dryness and nasal congestion and improve your comfort because the airflow generated from the device is often greater than what your body is accustomed to. You can adjust the humidifier settings to suit your personal needs and seasonal temperature changes. These days, most CPAP machines come with a built in humidifier.
