Distilled water is needed for humidification in Oxygen generators and CPAP machines. When water is used for humidification, it is important to have the minerals removed so they do not create deposits or scale in the water reservoir and tubing in Oxygen Concentrators or CPAP machines. This is why distilled water is often recommended as it has the minerals removed from the water.
Harvey DI+ water purification system is an alternative to distilled water.
