Is charcoal a purifier?
Adsorption binds impurities chemically on the surface of the charcoal filter rather than physically absorbing them. Activated charcoal is the ideal water filter because it removes toxins from the water without stripping the water of salts and important minerals.
Does charcoal absorb VOCs?
