Adsorption removes particulates via the activated coconut carbon fiber mesh surface areas, which adsorbs contaminants such as heavy metals, chemicals, pharmaceuticals, & herbicides as they pass by. Depth filtration (6mm thick) involves the removal of suspended waste products as they try to pass through the millions of layers of coconut carbon fiber.
