Keep water in copper pots overnight, and drink it in the morning to start your day with good health. This is what Rishi-Muni practiced years and years ago. Copper is a purifier and a boon to life. Please keep only cold or room-temperature water in the jug. Do not boil, and do not serve anything beyond water in it, as acidic drinks may cause the metal to erode. Holds 6.7 cups (1600ml) of water.
