Penta Ultra Purified Water uses a unique, patented 13-step, 11-hour filtration and purification process to ensure absolutely pure drinking water that is easy to absorb. Unlike most bottled waters that rely on chemicals to purify their water, Penta's unique process includes spinning the water under high speed and pressure (cavitation) to produces smaller, more readily absorbed water clusters that in turn provide advanced hydration. Penta is the only bottled water that uses patented physics, not chemicals to produce pure water to keep your body healthy and function at peak performance.
