The Philips Respironics Dreamstation water chamber is made with a stainless steel base designed to prevent corrosion. It has been well designed with no lid and this allows for easy cleaning and can be placed in the dishwasher.
The chamber will develop discolouration over time if used with tap water and the manual recommends usage of distilled water to prevent discolouration
