Getting more moist airflow into a CPAP mask is accomplished by both built in humidifiers and stand alone models. A built in humidifier is part of the machine and is non-detachable, although users can take out the water reservoir to clean or replace it.

Machine models with these kinds of humidifiers are more compact and easier to transport because there’s one less piece of equipment. Most patients who buy new CPAP machines choose ones with a built in humidifier.

Many older machine models and some newer ones don’t have built in humidifiers, so users purchase a stand alone version. These humidifiers are designed to be compatible with the majority of CPAP masks and machines. A short hose attaches them to the machine, and there are a number of different model types available.

Another type of humidifier is called an integrated humidifier, which is designed to be used with a specific machine. It attaches to the machine and does not have a power cord or a second hose.
