Our Carbon Block filter cartridges are extruded by high quality activated coconut shell carbon. Coconut shell activated carbon filters have a better filtration effect to chemicals like chlorine, organic compounds, and synthetic chemicals. Product Characteristics Made by active carbon particle loading body. Good adsorbability: can adsorb organic matter, heavy metal ions, and charged ions in the fluid. Dual functions:filtration and purification. Effectively:can remove the residual chlorine, odor, color and organic matter in the water. High flow; Fast adsorption;Long service life Application Pre-filtration treatment of drinking water R.O system prefilter Additional Details ------------------------------ Product description: Our Carbon Block filter cartridges are extruded by high quality activated coconut shell carbon.
