Rosedale's new Activated Carbon Fiber (ACF) filter bags are used for the removal of contaminants and impurities in liquids. The ACF bags boast a carbon fiber specific surface area rating of 1200m2/g. The immense amount of carbon fiber surface traps pollutants inside the pore structures. They can remove oils, heavy metals, organic compounds, solvents, aromatic and aliphatic hydrocarbons, as well as iodine.
