A large number of pores with different shapes are formed in the activation process of activated carbon, which constitutes a huge surface area with adsorption function, and its specific surface area is 500 ~1200m2/g. The larger the specific surface area, the better the adsorption effect. Both activated carbon and KDF can remove residual chlorine in water, but the reaction between KDF and chlorine produces zinc ion (Zn2+), which may lead to excessive zinc in water, while using activated carbon to remove chlorine has no such worry.
Proper amount of zinc is harmless to human body. Drinking water in the water purifier for a long time depends on the standard of the water purifier. If the water purifier is manufactured according to national standards, whether it meets national water quality standards is no different from bottled water.
