A water ionizer is an appliance that ionizes water. Although there is no empirical evidence that ionized water is beneficial to human health, it is marketed with claims that it is an antioxidant and can slow aging and prevent disease. Such claims contradict laws of chemistry and physiology and are often unfounded.
There is no empirical evidence to support claims made by manufacturers that drinking ionized water will have a noticeable effect on the body. Drinking ionized water would not be expected to alter the body's pH, due to the acid-base homeostasis.
Electrolyzed water has been used by the food industry to sanitize food products; though effective in bacterial solutions, it was found less useful when sanitizing utensils, surfaces and food products.
