A humidifier moistens the filtered air a CPAP machine pumps, helping prevent dryness in the user’s throat and mouth.
There are several types of humidifier including;
Built-in humidifiers which are enclosed within the main design of the machine.
Heated humidifiers which increase the efficiency of the humidification
Integrated humidifiers which are sold separately and are often of a proprietary nature, connecting to a specific brand of CPAP machine.
Waterless humidifiers which work by using the natural water vapor a user exhales to humidify the air for their next breath.
