Product Overview
This replacement humidifier water chamber is compatible with the Luna II CPAP Machine. It is designed to be accessible and easy to use with a front cap to easily fill up and a label with a Max fill-up line.
Replaced every 6 months to avoid the chamber to become cloudy or even pitted due to the mineral levels found in most tap and drinking water. As the material deteriorates, invisible cracks may trap bacteria from moisture.
