Granular activated carbon filter cartridge adopts natural fruit shell activated carbon, coconut shell activated carbon or medium high quality activated carbon and other high-quality activated carbon for water purification, can effectively remove the pesticides, pesticide residues, organic solvents and he industry caused by chemical pollution. Can effectively remove organic matter, residual chlorine and other radioactive substances in water, and have the effect of decolorization and odor removal. The activated carbon particle filter is filled in the plastic filter container without any chemical additives. The upper and lower sides of the container have multi-layer superfine fiber non-woven layers to prevent the release of carbon powder. The shell is made of ABS material ultrasonic welding process. Due to the long and wide contact between liquid and activated carbon particles, the function of removing chlorine, deodorization and deodorization is effective.
