Canadian-Owned Aftermarket DPF & DOC Supplier
Our Story
DPF Global was founded by Len Gaudette, building on years of hands-on experience running Len's Clean Air, Ontario's trusted name in professional DPF and DOC cleaning for commercial fleets. Working directly with fleet operators, Len saw the same problem again and again: paying OEM prices for DPF and DOC filters when quality aftermarket alternatives existed at a fraction of the cost. DPF Global was built to fix that — our own inventory, no middleman, shipped fast from our Canadian and U.S. warehouse.

Meet the Founder
Len Gaudette
Founder, DPF Global & Len's Clean Air
Len Gaudette founded DPF Global after years of running Len's Clean Air, Ontario's trusted name in professional DPF and DOC cleaning for commercial fleets. Seeing firsthand how often fleet operators overpaid for OEM replacement filters, Len built DPF Global to give Canadian truck and equipment owners a better option: quality aftermarket filters, shipped fast from our own inventory — backed by the same hands-on expertise that built Len's Clean Air's reputation.
Quality & Warranty
Every filter we stock comes with a 3-year, unlimited mileage warranty and material certification available on request. If a filter fails due to manufacturing defect within the warranty period, we replace it — no questions asked.
