An exhaust aftertreatment system for increasing fractional efficiency of diesel or gasoline particulate filters includes a particulate filter that includes a housing and a filter substrate positioned in the housing. The filter substrate is pre-conditioned with an aqueous solution or suspension configured to decompose or evaporate in response to exposure to heat so as to precondition the filter substrate.
