The mechanism of electrolysis has been extensively researched and has been deemed very safe in many studies (1, 2, 3, 4). It is important, however, to rinse your fruit and vegetables briefly under the tap using a colander after cleaning, to remove any remaining traces of the electrolysed water. You must not drink the (residual) water from the electrolysis process. Some people are put off by the smell of chlorine (bleach), but this is perfectly normal.
