When I changed from drinking water from a $4000 electric ionizer to the Cerra Water Pitcher I was impressed with an improvement in energy, regularity and clarity of thought. Because of my high blood pressure I had more peace of mind using the Cerra Water knowing that I was getting a balance of minerals rather than a high amount of sodium from my electrical unit. My Cerra Water pitcher consistently produces a PH of 9.5 and an ORP of around -400. I love being able to take our pitcher with us wherever we go out . and drink fresh alkaline water.
