Catalyzed Soot Filters (CSF)

BASF's Catalyzed Soot Filters (CSF) (also called diesel particulate filters or DPF) are designed to reduce emissions of particulate matter (PM) from diesel engines. The filters first trap particulates and then use a patented catalytic technology to continuously burn them at normal diesel operating exhaust temperatures.


  • Able to trap very fine particles including those below one tenth of a micron which includes most of the PM10
  • Can reduce particulate matter, carbon monoxide and hydrocarbons by 90+%
