PURPOSE: A refinement process of active charcoal and product containing charcoal manufactured thereby are provided to prevent contamination of the product which uses this as filler by fundamentally blocking the generation of dust within the active charcoal itself, protect the human body from generating dust, and integrally wash it without separating filler containing active charcoal. CONSTITUTION: A refinement process of active charcoal comprises the following steps. A step of repeating washing and dehydrating by injecting active charcoal of more than 90 gradient and rotating in forward and backward in the water; a step of repeating washing active charcoal had finished the first washing in a same step as the first washing with 0.01 - 0.1% of grass aqueous solution; a step of drying active charcoal within dryer; and a step of drying after dipping the dried active charcoal to 0. % - 0.5% of the grass aqueous solution. |
