Purifilter™ Passively Regenerating
  • Our industry leadership doesn’t stop with our DOC technology, the Purifilter™ was the first passively regenerating DPF to attain an industry leading 90% PM emissions reduction credit value*. Purifilters are more efficient as they are manufactured with Silicon Carbide substrates which offer superior filtration and durability compared to other DPF materials.
  • The Purifilter employs a base and precious metal catalyst impregnated onto the silicon carbide DPF surface to passively oxidize accumulated particulate while complying with stringent California Air Resources Board (CARB) limits on NO2 emissions.
  • The bottom line is that your investment in Purifilter™ delivers the most effective, durable and quiet solution to your environmental mandate.
