Measure, then act
No filter is cleaned before it is tested, and no clean is signed off before it is tested again. Every claim we make about a job has a number behind it.
About us
Specialists, not
a general workshop.
DPF Masters Pvt Ltd does one thing: diesel after-treatment. We restore filters that would otherwise have been replaced at many times the cost — and we tell customers when they do not need us at all, because a filter is a symptom and we would rather find the cause.

Why we exist
Because replacement became the default answer
When BS-IV arrived, the standard response to a blocked filter was a new one. The parts were expensive, the diagnosis was thin, and a great many perfectly serviceable substrates went to scrap.
A diesel particulate filter is a ceramic substrate, not a consumable. In the overwhelming majority of cases a blocked one has simply run out of the ability to regenerate itself — which is a cleaning problem, not a replacement problem. The physics said so; the industry was not set up to act on it.
So we built around measurement instead. Every filter that comes through is tested before we touch it and tested again before it goes back, on a calibrated flow bench. That single habit is what separates a repair from a result, and it is why we can put a number behind every claim on this site rather than an adjective.
It also means we occasionally do the commercially stupid thing and tell someone their filter is fine, their sensor has drifted, and the job is a fifth of what they were quoted elsewhere. We would rather have that customer for a decade.

How we work
Four things we do not compromise on
These are not aspirations on a wall. Each one costs us money in a specific, predictable way, which is how you can tell they are real.
Diagnose the cause
A blocked filter is a symptom. If we clean it without finding out why it blocked, you will be back in four months — and we will have failed you.
Restore, do not replace
A replacement filter costs many times what a clean does. We treat replacement as the last resort it should be, not the first quote.
Document everything
Photographs, torque figures, flow results and root cause, issued as a report you keep. Your next engineer should not have to guess what we did.

Capability
What being a specialist actually buys you
A general workshop can remove a filter. Whether what happens next is a repair or an expensive guess is a different question.
Factory-level training
Certified DPF Specialists
Technicians trained and assessed specifically on diesel after-treatment systems — not general mechanics who also attempt filters.
Flow-bench verified
Advanced Cleaning Technology
Thermal and pneumatic cleaning equipment with calibrated flow benches, so every result is measured rather than asserted.
Assessed before charged
Restore Rather Than Replace
A replacement filter costs many times what a clean does. We assess whether cleaning will actually work before you are charged for it — and tell you plainly when it will not.
Same-day turnaround
Same Day Service
Most passenger and light commercial jobs are completed within a single working day. Fleet work runs on a loan filter pool for zero downtime.
Solvent-free
Eco Friendly Cleaning
A water-and-air based process with no aggressive solvents, and full capture and disposal of extracted ash under regulation.
12-month warranty
Warranty on Cleaning
Every clean carries a written warranty on flow restoration, backed by the documented before-and-after test results.

Reach
Workshop-based, nationally deployed
Retail and light commercial work runs through the workshop. Fleet and off-highway work goes to the vehicles — mobile units deploy to depots, yards, quarries and mine sites across the country.
- Filters accepted by courier from anywhere in India
- Mobile cleaning units for sites where machines cannot travel
- Site induction, permit-to-work and PPE compliance handled as standard
- 24/7 escalation line for fleet customers under contract
