Replacement standard water chamber for the H5i Heated Humidifier for use with ResMed S9 machines. Unlike chambers for other machines, the H5i water chamber easily lifts up, so cleaning or replacing the chamber is quick and easy. This water chamber is not machine washable. Each chamber holds a maximum of 380 millilitres of water.

For best results, fill with room temperature distilled water and empty every day. Do not put any chemicals or additives into the water. Replace the standard water chamber every six months or when necessary to keep your CPAP machine working like new. This also ensures the effectiveness of your sleep therapy.
