Activated carbon is a porous carbon material with highly developed pore structure. This porous structure provides it with a large surface area, enabling it to fully contact gases (impurities) and thus possesses adsorption properties. When the pore structure of activated carbon is slightly larger than the diameter of harmful gas molecules, optimal adsorption can be achieved. Therefore, coconut shell activated carbon can effectively adsorb and remove harmful substances and odors from water, enhancing the safety and taste of the water.

Note that coconut shell activated carbon has limited adsorption capacity and needs to be replaced regularly to maintain its effectiveness. Additionally, coconut shell activated carbon has strong regeneration capabilities, which can be reactivated and reused through certain methods, thereby reducing costs and resource waste.
