Does The Coconut Shell Activated Carbon in The Water Purifier Need To Be Replaced Regularly?

Coconut shell activated carbon is generally obtained by using coconut shell as raw material, heating it at high temperature while isolating the air, and continuously introducing water vapor to remove wood gas, wood tar and other substances decomposed by heating. Its main component is carbon , so it looks dark. Coconut shell activated carbon is covered with tiny pores inside and out, so its surface area is particularly large. It has been calculated that the surface area of 1 gram of coconut shell activated carbon can reach 500-1000 square meters. This makes coconut shell activated carbon have strong adsorption ability, and people can use it to absorb harmful substances in water or air to purify water or air.

  Coconut shell activated carbon mainly plays a filtering and adsorption role in the water purifier. If it is used for a certain period of time, the coconut shell activated carbon will be saturated with adsorption. Once it is "full", it will lose its purification function, and as time goes by , the adsorbed substances and the coconut shell activated carbon itself will also retain some microorganisms and bacteria.

Therefore, coconut shell activated carbon placed in a water purifier or filter tank cannot be used for many years. After using it for a certain period of time, it is best to replace the coconut shell activated carbon in the water purifier or filter tank in time. It should be three months to half a year, and generally not more than one year at the longest. Then you should consider replacing it with a new coconut shell activated carbon. . Although coconut shell activated carbon does not dissolve in water, even if some small particles float in the water, drinking it will not cause harm to the body, but you still need to pay attention to the cleanliness of the water purifier.
