Increase the purification effect of carbon by 150%

1. Pour the carbon into a stainless steel saucepan, and fill with at least twice as much boiling water.

2. Stir with a large spoon, allow the carbon to sink to the bottom of the saucepan before discarding the surplus water. Repeat the process 4-5 times, making sure all soluble substances in the carbon have been washed out.

Cover with boiling water, put a lid on the saucepan, and leave it to soak for 24 hours. It is the internal wetting within the carbon granule that mostly increase the purification effect. Those 24 hours add 50% more so we can use the whole capacity of the activated carbon.

3. Discard surplus water and cover once more with hot or boiling water.

3. Stir and pour off remaining water.
