Activated charcoal consists of small, black beads or a solid black porous sponge. It is used in water filters, medicines that selectively remove toxins, and chemical purification processes.
The most common everyday use of activated charcoal is to filter water. It improves water clarity, diminishes unpleasant odors, and removes chlorine.
It will filter:
- Some drugs
- Hydrogen sulfide and some other volatile compounds that cause odors
- Small amounts of metals, such as iron, mercury, and chelated copper
