We all know that the filter cartridge is the core component of all water filters, and the activated carbon filter cartridge is the most commonly used filter element in water purifiers.Because activated carbon can physically adsorb contaminants, it does not cause pollution, has no side effects, and is inexpensive. Therefore, activated carbon is a relatively common filter cartridge material in water purifiers. So can the activated carbon cartridge in the water purifier be used for a long time, and why should it be replaced regularly?
Because activated carbon is usually made of nut shells and trees. For example, activated carbon filter material of HUATAN FILTER is made of coconut shell certified by NSF.These materials are heated at high temperature under the condition of being isolated from the air, and continuously pass water vapor, and finally remove the wood gas and wood tar that are decomposed by heating due to heat. The remaining main component is activated carbon.
The activated carbon is covered with tiny pores inside and out, 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 adsorb harmful substances in water or air to purify water or air.
The activated carbon filter cartridge mainly plays a filtering and adsorption role in the water purifier, but after a certain period of time, the adsorption performance of the activated carbon filter cartridge will saturate and will lose its purification function.And with the increase of the use time, the adsorbed substance and the activated carbon filter itself will also retain some microorganisms and bacteria.
