Water ionizers are plastic or metal electronic filtration units that are usually of a small size and contain all the components necessary to convert normal water into alkaline. When regular tap water enters a regular alkaline water (ionizer) device the carbonate minerals which are calcium and magnesium minerals are converted into hydrate minerals and this process is known as the electrolysis process and after connecting the water ionizer to the kitchen tap it will be given direct access to your water supply Thus all water atoms will be ionized by your ionizer before being used for drinking, cooking or cleaning.
