What goes through the shop.

Every filter that comes through Proflo runs the same certified process — cleaned, inspected, data-logged, and shipped back ready to run. Here's the full breakdown.

01 — The Level 4 Process

Liquid, thermal, and air — in that order.

Our Level 4 cleaning process combines blast, thermal, and liquid cleaning technologies. It's built to fully restore flow through the substrate without the stress a single-method clean puts on the ceramic core.

  • Liquid wash breaks down oil ash and soot
  • Thermal bake removes residue without substrate stress
  • Blast & air clears channels to OEQ spec

02 — OEQ Reman Program

12-point inspection. Every filter, every time.

Our focus is cleaning, not parts replacement. Unlike other reman programs, we clean your filters and return them to you — we don't push a new part when yours can be restored.

  • 12-point inspection process on every unit
  • Data collected & stored for statistical trend analysis
  • Full certification on return

03 — What We Clean

DPF and DOC. Heavy duty to automotive.

  • DOC cleaning — all classes
  • New DPFs supplied when a unit can't be saved
