Westinghouse AquaVie countertop Healthy Water System provides cutting edge technology that mimics the natural hydrolic process of the earth to provide 99% pure water in the comfort of your own home. The AquaVie is bPA free. The purity of water is much higher than most filter systems but without the wasteful packaging associated with bottled water and the added cost of different replacement filters. Water inside the transformation chamber of the AquVie is converted into steam while leaving the contaminants behind in the chamber. The steam then condenses into pure water droplets that percolate through a proprietary cartridge of calcium and magnesium to add heart healthy minerals to create perfectly balanced 99% pure water with a natural taste that is preferred over bottled or tap water.
