There are basically two types of CPAP humidifiers: the passover humidifier and the integrated humidifier.
A water chamber is the main component of a passover humidifier. Before air flows to the hose/tubing of a CPAP machine, it first passes over the water chamber before the patient can inhale it. It helps add moisture to the airflow thus reducing the risk of nasal irritation.
An integrated humidifier directly fits a CPAP machine so there is no need for an extra hose or power cord. It is easy-to-use because it more compact compared to other types of humidifier.Tags: dry, integrated, passover, humidifier
