How to replace the activated carbon in Cohen water

  • Detail

Many users know that the filter element is the essence of all water purifiers. Because activated carbon is physical adsorption, there is no pollution, no side effects, and the price is low, activated carbon is a common filter element material in water purifiers. Can the activated carbon in the water purifier be used for a long time? Why should it be replaced regularly

the activated carbon in the water purifier needs to be replaced regularly

because the activated carbon is generally made of fruit shell, branches, etc., heated at high temperature under the condition of isolation from the air, and continuously injected with steam to remove the wood gas, wood tar and other substances decomposed by fruit shell, branches, etc. due to heating. Its main component is carbon, so it looks black

the activated carbon is full of small pores inside and outside, so its surface area is particularly large. After calculation, the surface area of 1 gram of activated carbon can reach 500-1000 square meters. This makes activated carbon have strong adsorption ability. People can use it to adsorb harmful substances in water or air to purify water or air

however, activated carbon mainly plays a role of filtration and adsorption in the water purifier. If activated carbon adsorption is saturated after a certain period of time, once it is "full", it will lose its purification function, and with the growth of time, some microorganisms and bacteria will remain in the adsorbed substances and activated carbon itself

therefore, the activated carbon placed in the water purifier or filter can not be used for many years. After a certain period of time, it is best to replace the activated carbon in the water purifier or filter tank in time, preferably from three months to half a year. Generally, the longest time is not more than one year, and it is necessary to consider replacing the activated carbon with a new one. Although activated carbon will not dissolve in water, even if some small particles float in the water, drinking it will not cause harm to the body, but we should still pay attention to the cleaning of the water purifier
