The activated carbon filter cartridge machine is made by adding activated carbon particles and a binder to heat and sinter. The innermost layer of the filter element is a polypropylene skeleton to enhance the compressive strength of the filter element. The framework is covered with two layers of polypropylene microfiber felt, which can intercept the liquid through the carbon filter and bring out particles larger than 10 microns. The outer layer of the melt-blown filter element is covered with two layers of polypropylene ultra-fine fiber felt, which can intercept particles larger than 10-20 microns in the liquid, so that the filter element has the dual functions of filtration and purification. The outermost layer is a white plastic mesh cover, which gives the filter element a complete appearance and neat appearance. The two ends of the filter element are equipped with soft nitrile rubber end caps, so that the filter element has a good seal after being installed in the filter cartridge. The finished activated carbon filter is tightly sealed with a plastic film to prevent the filter from being polluted and keep the filter in a fresh state. Activated carbon filter has a good adsorption effect, which can effectively remove residual chlorine, odor, color and organic matter in water.
