Yes, StayPure preserves and protects water while it is being stored.  This is achieved by the combined technologies of StayPure; it continuously reacts and interacts with the water.  It adsorbs and absorbs impurities whilst also releasing valuable trace minerals in accordance with the demands of the water. It also functions to achieve and preserve a natural balance of trace minerals and pH in the water. Furthermore, StayPure functions as an oxidation catalyst that serves to oxidise the water, preserving and protecting it from contamination.
