Abstract – In accordance with the defined requirements of the SRPS 8748, SRPS EN 14387 standard and the existing equipment, this work shows the results of the comparative tests of sorptive properties of the Filter М3 and the Filter М4 with the standard recipe and the altered recipe for the impregnation of activated carbon, upon   phosgene, chloropicrin, ammonia, sulphurdioxide and chlorine challenge at different concentrations, relative humidity and flow of the inlet gas mixture for the standard quantity of active filling of the Filter М3.

Key words- active filling, impregnation of activated carbon, filters, sorptive properties of the filters and the efficiency of filtering.
