The objective of this study is to manufacture an efficient activated carbon fiber (ACF) assemblies filter. Cellulose acetate and phenolic resin were dissolved in acetone and coated on a 2 cm-long and 2 cm-wide stainless steel mesh. Various concentrations of cellulose acetate and phenolic resin in acetone solution were examined for the extent of coating on the stainless steel mesh using a thermogravimetric analyzer (TGA), a surface area analyzer (BET) and a microscope. As a result, the best quality of coating on the stainless steel mesh was obtained with 2 wt,% cellulose acetate and 10 wt,% phenolic resin in acetone solution. The ACF filter was also impregnated with ZnCl2, KOH, H3PO4 and Na2CO3, respectively to enhance its adsorption capacity. Iodine number increased by impregnating with the chemical compound in the following order: KOH > ZnCl2> Na2CO3> H3PO4. Iodine numbers for the ACF filters impregnated with ZnCl2 (ACFz) and KOH (ACFK) were found to be 972 ~ 1,117 mg/g and 987 ~ 1,183 mg/g respectively.
