What is the difference between carbon and “activated” carbon? The carbon used in air purifiers and water filters is put through a baking process to dry the carbon. The heat during this process drives out impurities and causes the carbon to fracture at a microscopic level. Doing this opens up a large surface area where contaminants are captured. After activated carbon has fully absorbed a large volume of pollutants, heating it again will reactivate it; however, the reactivation process is impractical and dangerous.
