Activated carbon is treated or activated with oxygen to give it tiny holes and make it absorbent like a sponge. This solid block of porous carbon creates a chemical reaction when water passes through which absorbs chlorine and other organic materials. There is a 5-micron membrane surrounding the activated carbon block filter to trap any particles that may detach during the water filtration process.
