Philips Respironics DreamStation Humidifier Dry Box Assembly is required for Respironics DreamStation CPAP humidifiers. It is the path of the heated and humid airflow from the humidifiers to DreamStation CPAPs.
This assembly does not include the DreamStation dry box inlet seal.
The unique design prevents accident water spills. However it is not 100% one direct valve! Still handle your humidifier with care when it has water filled.
How to remove the dry box assembly
Use one finger to push the clip, and use your another finger to pull the assembly from the airflow outlet.
