I got my charcoal from a pet shop that sells fish tank supplies. The charcoal seems to be super active. I have been using it to filter drinking water. Our tap water is just poisonous and disgusting. I taped a cloth around the spout of a large funnel and filled the spout with the charcoal and poured the water through. You can't buy a better water filter.
