Along with the unique baffle design, the water chamber allows the airflow to collect more humidity. DeVilbiss designed the chamber to hold enough water for a full night's sleep. At the humidifier's highest setting, you can still expect a full 8 hours of humidification.

This dishwasher safe humidifier chamber is constructed of strong Lexan (polycarbonate resin thermoplastic) and has a stainless steel heat transfer plate. The chamber is easy to remove and replace and it includes built-in overfill protection which prevents humidifier water from damaging the CPAP!
