ly and may not always be available for purchase.
He says this is because some OEM core exchange
remanufacturing programs will prioritize use of
these new OEM filters to replace failed filter cores
if the returned core is deemed unfit to reuse.
"When they get a filter back and it's bad, they have
to seed that with a new filter, so some of the remanufactured [DPFs] out there end up being brand new
filters because [with] a failed
part, you'd have to bring a part
in to replace that, otherwise you
run out of filters eventually,"
Anderson says.

tionable results. The term 'remanufacture' itself is a
misnomer as there are no parts replaced as there are
with [other] remanufactured products."

Conclusion

Though replacing a DPF is something fleets hope to
prevent through careful maintenance and cleaning,

it cannot always be avoided. When it comes to choosing a replacement DPF, be sure to keep in mind any
recommendations from the engine's OEM, budget,
driving routes, and the reputation of the company
you are buying the replacement DPF from.

Aftermarket
An aftermarket filter can come
from a number of suppliers who
have replicated the filter, says
Daimler's Gedert. Aftermarket
filters are typically less expensive than OEM filters, and there
are more options to choose
from, but aftermarket DPFs
are banned in California as
most do not follow the same
efficiency standards required
in OEM DPFs.
Additionally, DPF performance may be hindered.
"The consequence of using
aftermarket DPFs that don't
meet OEM specifications may
result in system performance
fault codes," Volvo's Moore says.
Reman
Remanufactured DPFs are
reused substrates, Just says,
that were in another vehicle,
but have been cleaned and
certified and should provide
the same level of life expectancy as an OEM DPF. Just
cautions, however, that if the
remanufactured DPF was
not remanufactured for OEM
purposes it may not be meeting
the EPA/CARB specifications.
Remanufactured DPFs
are the least costly of all the
DPF replacement options,
but they are also banned in
California. Fleets should take
any non-OEM remanufactured
DPFs into careful consideration before buying them.
"There is no history to where
this filter came from or how it
was treated by its previous
owner," Koukal says. "If the
previous owner mistreated the
aftertreatment system by ignoring regenerations or prolonging
cleaning intervals or if there
was a catastrophic failure that
occurred, the DPF's life could be
compromised. Also, the process
used to remanufacture a filter
has shown to provide ques-
