Store water in a copper container

Keeping water in a copper bottle/jar overnight or for 4/5 hours helps to purify water. This has been proven with the scientific experiment.

Spiritually, it is believed that water has memory. Since it travels through various pipes to reach your tap, it may acquire negative energy, keeping it in a copper container helps to bring back the water to its original positive state.

I would recommend storing filtered water in copper jars/bottles/containers overnight and drink it the next day.

I have ordered a copper jar from the below website and I am happy with the quality. 

I prefer a jug over a bottle as it’s very convenient to clean it.
