As we all know, the filter element is the core element of the water purifier. Because activated carbon is physical adsorption, no pollution, no side effects, and low price, activated carbon is a relatively common filter material in water purifiers.
So, can the activated carbon filter element in the water purifier be used for a long time, and why should it be replaced regularly?
Activated carbon has a strong adsorption effect
Because activated carbon is generally made of husks, branches, etc. as raw materials, it is heated at high temperature in the absence of air, and water vapor is continuously introduced to remove wood gas, wood tar and other substances decomposed by heat such as husks and branches. Yes, its main ingredient is charcoal, so it looks black.
Activated carbon is full of tiny pores inside and out, so it has a particularly large surface area. 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, and people can use it to adsorb harmful substances in water or air to purify water or air.
Activated carbon filters need to be replaced regularly
The activated carbon filter element mainly plays the role of filtration and adsorption in the water purifier. If it is used for a certain period of time, the activated carbon adsorption is saturated. The substances and activated carbon itself will also retain some microorganisms and bacteria.
Therefore, the activated carbon filter element in the water purifier cannot be used for many years.
After using it for a certain period of time, it is best to replace the activated carbon in the water purifier or the filter tank in time.
Unlike other electrical appliances, water purifiers cannot be bought once and for all. Therefore, in order to avoid drinking "sewage" caused by secondary pollution, we must pay attention to the regular replacement of the filter element of the water purifier!
