A common complaint of CPAP users is that humidification systems could not last through-out the night. In addition, cleaning humidifier chambers proved to be a challenge.

The DeVilbiss solution is a unique calmshell humidifier chamber design. The IntelliPAP humidifier chamber features a large flat surface area, as opposed to the jar-type humidifiers that have become an industry standard. Inside the chamber is a series of baffles along a snaking path in which the air flows. By directing the airflow and creating turbulence, the air flowing through the chamber can pick up more humidity. In addition, by creating a larger surface area, the level of the water is shallower, which also allows for a more humid air flow delivered to the CPAP user. The clamshell design allows the chamber to be split into two pieces – making cleaning easier.
