Activated carbon filters are used for decolorization, odor removal, and adsorption of impurities like endotoxins, proteins, and chlorinated compounds. Ideal for polishing steps in biologic manufacturing, they offer high surface area and customizable cartridge or capsule formats. These filters are used in pre-formulation, water treatment, and final formulation stages. With low extractables and high adsorptive efficiency, carbon filters support compliance in regulated environments. Activated carbon is often combined with prefiltration to create hybrid depth-carbon modules for enhanced process outcomes in cGMP operations.
