We all know that the filter element is the essence of all water purifiers, and since activated carbon is physically adsorbed, has no pollution, no side effects, and is inexpensive, activated carbon is a relatively common filter material in water purifiers. Can activated carbon 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 activated carbon is generally made of fruit shells, branches, etc., it is heated at a high temperature in the presence of air, and water vapor is continuously introduced to remove wood gas, wood tar, etc., which are decomposed by heat, such as shells and branches. Its main ingredient is charcoal, so it looks dark.
The activated carbon is covered with 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 a strong adsorption ability, people can use it To absorb harmful substances in water or air to purify water or air.
However, activated carbon plays a role of filtration and adsorption in the water purifier. If a certain amount of time is used, the activated carbon is saturated and once it is 'satiated', it will lose its purification function, and as time goes on, it will adsorb. The substance and activated carbon itself will retain some microorganisms and bacteria.
Therefore, the activated carbon placed in the water purifier or the canister can not be used for many years. It is best to replace the activated carbon in the water purifier or the canister in a timely manner after a certain period of time, preferably from three months to six months. For more than one year, it is necessary to consider replacing the new activated carbon. Although the 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 it is necessary to pay attention to the cleaning of the water purifier.
