Philips Respironics’ DreamStation Humidifier Dry Box Assembly is the replacement assembly used to prevent water damage to the DreamStation Heated Humidifier.
Dry Box technology is used on PR humidifier systems to protect the device from potential water leakage. In the instance that water may seep or spill from the water chamber into the unit, the dry box is designed to capture the water to keep it from spreading throughout the humidifier and CPAP therapy device.
The Dry Box Assembly has an inlet seal located on the interior of the humidifier as well as a smaller seal located on the exterior of the unit where the machine and humidifier meet.
Please Note: Only the interior, inlet seal is intended to be replaced. If the seal on the exterior of the humidifier assembly is damaged, a new assembly must be purchased.
