What Is A DPF Catalytic Converter?

A “DPF” or Diesel Particle (particulate) Filter is part of the exhaust system on a diesel engine. The DPF is part of the exhaust system on a diesel engine. With today’s EPA guidelines for emissions, the New, Large Diesel trucks have a DPF and a catalytic converter to reduce emissions, whereas older vehicles may only have a DPF.


DPF Cats are becoming more and more common as automakers add more diesel vehicles to their fleet offerings. The confusing part about DPFs is that they often come with 1-3 units per car or truck.

These different units do not always have the same value, which is confusing. Those units also could have very high or low values depending on the serial numbers. We always ask for all listed numbers to cross-check our database for the most accurate price quotes.
