Replacement water chamber for the PR System One Heated Humidifiers.

The clear lid is compatible with the 50 and 60 series Respironics machines. The dark gray lid is compatible with the 60 series TS Respironics machines. The standard H5i Humidifier Chamber is not cleanable and cannot be disassembled. The standard H5i Disposable Water Chamber cannot be taken apart and is recommended to be replaced every 6 months.

The Chamber will hold 380 ml of water (when properly filled to the fill line). Chamber should be filled with clean water each night. Using distilled water is not required, but it will maximize the life of the chamber and reduce mineral deposits.
