A water ionizer (also known as an alkaline ionizer) is a home appliance which claims to raise the pH of drinking water by using electrolysis to separate the incoming water stream into acidic and alkaline components.[1][2][3] The treated water is called alkaline water. Proponents claim that consumption of alkaline water results in a variety of health benefits, making it similar to the alternative health practice of alkaline diets. Such claims violate basic principles of chemistry and physiology.[4] There is no medical evidence for any health benefits of alkaline water. Extensive scientific evidence has completely debunked these claims,[5][6][4] leaving such claims in the pseudoscientific realm.[4]
The machines originally became popular in Japan and other East Asian countries before becoming available in the U.S. and Europe.
