The H5i Cleanable chamber is designed for the H5i Humidifier which attaches to the S9 CPAP series. It has a stainless steel base and can be opened for cleaning and has a water measurement gauge to tell you where to fill the water level to.
The stainless steel base prevent corrosion but it is still recommended that it is used with Distilled water. The simple clipping system prevents water leakage and assists in preventing water entering into the CPAP machine.
