Carbon fiber filter element not only has the inherent characteristics of carbon material, but also has the soft processability of textile fiber. It is a new generation of adsorption material. More than 80% of the carbon atoms of the carbon fiber filter element are located on the inner and outer surfaces, forming a unique adsorption structure. It is a surface solid. In addition to chlorine, lead and peculiar smell, it is used to filter the sediment; economical. It is widely used in water treatment and purification, color removal, deodorization, organic matter removal, air purification devices, ozone filters, nuclear pollution air purification devices, gasoline traps and other industries.
