Pure Eau Water Purifiers use reverse osmosis to remove all contaminants from mains supplied water.

This demonstration involves passing an electrical current through a number of different types of drinking water; tap, spring or mineral water and tap water filtered through a domestic filter.

As the electrical current is introduced, a reaction can be observed in some of the glasses that indicates the presence of conductive metals - contaminants in the water. As the reaction continues you will be astounded by the amount of contamination present in drinking water that previously seemed crystal clear. Only the sample purified by the process of reverse osmosis remains clear and clean.
