Coconut shell-activated carbon has a very high hardness and more abrasion resistant than any other type of activated Carbon. It's a fully natural, eco-friendly product, that has a very small carbon element. It's come from coconut shells. The coconut-shell carbon can efficiently absorb impurities with micropore molecular structures of more than 85%, such as those present in drinking water. The Main difference between its chemical and physical characteristics and also high abrasion resistance.
