humidifire question

I was just wondering what is the benefit of the heat feature on my bipap machine I am always told by my friends that I don't need to use the heat at night and I will still get humidification in my hose without the heat turned on, how true is this because I am concerned about getting dry mouth in the middle of the night.

If you don't heat the water, you will get a little humidity from the water. If you need more, the way the CPAP humidifier gets your more water is by heating the water. The warmer the water, the more humidity.

The amount of humidity in your breathing air will depend on the room temperature and humidity, and on the design of the humidifier and the temperature of the water.

Some machines sense the temperature and humidity of the room air and take it into account when they control the heat of the the water tank.
