Activated charcoal is the ideal water filter because it removes toxins from the water without stripping the water of salts and important minerals. Because impurities are kept in the filter, it's important to replace your carbon every 12 months to ensure it continues to work as it should.
Carbon filtering works by adsorption, in which pollutants in the fluid to be treated are trapped inside the pore structure of a carbon substrate. The substrate is made of many carbon granules, each of which is itself highly porous. As a result, the substrate has a large surface area within which contaminants can be trapped. Activated carbon is typically used in filters, as it has been treated to have a much higher surface area than non treated carbon. |
