About us

Founded in 2020, DPF Bros has built its reputation on expert diesel emissions cleaning, diagnostics, and repair services. Originally operating as Diesel Emissions Specialists in Cincinnati, Ohio, we focused on helping commercial truck owners, fleets, and repair shops maintain peak performance through professional cleaning and restoration of diesel aftertreatment systems.

With years of hands-on experience servicing Diesel Particulate Filters (DPFs), Diesel Oxidation Catalysts (DOCs), SCR systems, EGR components, and complete One Box assemblies, we became a trusted name in the diesel industry. Our expertise in cleaning, diagnosing, and repairing emissions systems has helped customers reduce downtime, improve efficiency, and extend the life of critical components.

As we worked closely with fleets, owner-operators, and repair facilities, we recognized a growing demand for affordable, dependable emissions parts backed by real-world experience. This led to the creation of DPF Discounter, our online parts division dedicated to providing high-quality DPF, DOC, SCR, EGR, and One Box solutions at competitive prices.

What sets DPF Bros apart is that every product and service we offer is backed by practical industry knowledge. We don't simply sell parts—we provide proven solutions that have been tested and trusted through our own operations. From professional cleaning services and emissions system diagnostics to OEM replacements and cost-effective aftermarket options, our team is committed to helping customers keep their trucks running clean, efficient, and compliant.

Whether you need expert cleaning services, reliable emissions parts, or technical guidance from experienced professionals, DPF Bros is here to support your business—every mile of the way.
