Water purifier is usually a basic device for home use that filters chemicals and impurities. Purifiers are unable to change the pH values, ORP values or the structure of water molecules. A water ionizer uses electrolysis to alter water pH and ORP values and molecular cluster structures of the water. It regulates the water chemistry for the user as per their needs. The pH value of the output can be selected for different uses; drinking, cooking, washing, healing, beautification etc.
