Carbon is a commonly-used medium in water filtration processes. In fact, nearly every type of water filter system–whether it’s a backpacking water filter, refrigerator filter, shower filter, pitcher filter, reverse osmosis water filtration system or whole-house filter–utilizes carbon filtration in some way.
Carbon filters for water filtration are produced by grinding up a carbon source.
This carbon source could be:
- Bituminous coal
- Coconut shells
Carbon filters remove contaminants through adsorption.
