From the Manufacturer:
The Enviro Products Alkaline Pitcher Filter adds negatine hydroxyl ions, which lowers the ORP (oxidative reduction potential)* giving the water molecules a negative charge. Water from the Enviro Products Alkaline Pitcher Filter has an ORP ranging from -200 to -400. The lower number, the better. It also raised pH to 8.5-9.5 by adding the perfect balance of naturally ionized magnesium, potassium, calcium, and sodium.
