// Cleaning

A documented cleaning line

Every filter runs the same process — so you get verified airflow back, not a guess.

  1. 01

    Inspect & weigh

    The incoming filter is logged, weighed on the soot scale and flow-tested to set a baseline.

  2. 02

    Thermal regeneration

    A controlled bake in the regeneration oven converts trapped soot to ash.

  3. 03

    Aqueous flush

    The flush booth drives water and air through every channel to pull the ash out.

  4. 04

    Dry

    The filter is fully dried before final testing.

  5. 05

    Blast & detail

    Inlet and outlet faces are finished in the blast cabinet.

  6. 06

    Verify & report

    Final weight and airflow are measured and documented against the baseline.

// FAQ

DPF questions, answered

Should I clean or replace my DPF?
If the filter is structurally sound, cleaning restores airflow for a fraction of replacement cost. If it's cracked, melted, or past its service life, a new DPFXFIT filter is the better call — we'll tell you straight after inspection.
Do you clean DOC and SCR too?
Yes — DPF, DOC, SCR and EGR. Each gets the right combination of thermal and aqueous cleaning, with documented before-and-after soot weight and airflow.
How long does cleaning take?
Most filters move quickly through our standardized line. We'll give you a firm turnaround when you drop off — or when we pick up.
Do you offer pickup and delivery?
Yes — free pickup and delivery along the Wasatch Front.
What comes with a new filter?
DPFXFIT filters ship complete with OEM-quality clamps and gaskets, and are backed by a 3-year, unlimited-mileage warranty.
What vehicles and equipment do you cover?
On- and off-highway diesels from 2007 and newer — trucking, construction, agriculture, generator sets, transit and more.
