Activated carbon is a hydrophobic adsorbent made of carbonaceous materials through high temperature carbonization and activation. Activated carbon contains a large number of micropores, which can adsorb organic pollutants and some inorganic substances. It mainly plays the role of filtration and adsorption in the water purifier. If it is used for a certain time, the pores of activated carbon will be saturated and the adsorption will be reduced to zero.
Moreover, with the increase of time, the adsorbed substances and activated carbon itself will retain some microorganisms and bacteria, so it is best to replace the activated carbon in the water purifier in time after a certain period of use.

Types and functions of activated carbon filter element in water purifier
1, compressed activated carbon filter element
Function: Adsorption of residual chlorine, odor and pigment, removal of organic matter.
2. Sintered activated carbon filter element
Function: remove residual chlorine, decolorize more than 98%.
3. Activated carbon hollow fiber composite filter.
Function: Made of sintered activated carbon filter core and imported hollow fiber, it not only has the function of sintered activated carbon filter core, but also has sterilization effect.
4. Granular activated carbon filter element
Function: Adsorption of residual chlorine, odor and pigment, removal of organic matter and residual pesticides.
People's health network-activated carbon is not so magical? Failing to replace or re-release harmful gases in time.
