Dental water distillers heat water to produce steam, then cool the vapor so it condenses into distilled water while many nonvolatile minerals remain in the boiling chamber. In dental settings, distilled water is commonly used where equipment manufacturers specify mineral-reduced water, including certain autoclave reservoirs and other compatible devices. This category includes countertop distillers with model-dependent chamber capacity, output rate, power requirements, collection containers, and construction materials. Review capacity, production rate, maintenance instructions, voltage, and intended application before selecting a unit carefully.
