We proposed a new dry cleaning for air filters, particularly chemical filters, by using supercritical carbon dioxide. The regeneration of chemical filter media loaded with diethyl phthalate and toluene were investigated in terms of the breakthrough curve after cleaning at various cleaning conditions. The recovery of filter media loaded with diethyl phthalate and toluene were higher 90 % in some suitable temperature and pressure conditions. And, we investigated cleaning performance for not only single component gas but also multicomponent gases. The recovery of filter media adsorbed various gases were higher 99 % at the pressure from 10 to 20 MPa and the temperature of about 45℃.
