Our drinking systems do not require electricity. Many products use electrolysis to Ionize water. However, water passing through the machine cannot be purified if electrolysis is to work. This means that whatever is dissolved into the water, including any and all contaminants, becomes ionized as well, meaning contaminants are more easily absorbed by the body in ionized water. A Sorso system purifies the water and then adds essential minerals that are ionized back into it, ensuring that your body is only absorbing the "good stuff.
