How to start a DPF cleaning business in India
Everything before the sales pitch: what the work actually is, who succeeds at it, what you earn per filter, the space and power you need, the licences to arrange, and what your team has to learn. Read it, then decide.

Four things come through the door
A DPF machine is not a single-service purchase. Each component type is a different customer and a different ticket size.
Car & SCV filters
Your volume business. Most common on Indian roads, blocked mainly by city driving that never completes a regeneration.
Truck DPFs
Fewer units, much higher ticket — bigger filters, longer cycles, and fleets that book in batches.
DOC units
Oxidation catalysts, often flooded with oil after a turbocharger failure. Common, and rarely serviced anywhere.
SCR & AdBlue
Urea crystallisation inside the catalyst. Almost nobody in India cleans these — which is exactly why fleets ask.
Four things you need to know before getting started
From startup costs to monthly earnings, here’s what you need to know before you begin.
New to DPF cleaning?
Three things stop most people from starting: infrastructure, skilled labour, inventory. DPF cleaning asks for almost none of them. One machine, your existing bay, your existing team. We handle the training and stay available.
When will I start earning?
You can generate revenue from the first day of operation if you actively take care of promotion while waiting for the machine to be delivered. With the right preparation and customer contacts, you will be ready to provide services from the moment you launch the service.
When can I expect a return on investment?
Usually our customers in Europe are able to pay off the lease installment of the machine after just 4-6 cleanings per month. Each additional cleaned filter is pure profit for you!
How much do I have to invest?
To get started, all you need to do is invest in a machine priced in between 7.5 Lakhs a month (leasing). For this, you need a space of about 30 m² - enough to install the equipment and serve customers comfortably.
Four kinds of business that make it work
The pattern is consistent: the ones who succeed already have diesel vehicles or diesel customers. The machine adds a service, rather than starting a business from zero.
Multi-brand car garages
You already see BS6 diesel cars every day, and you are currently sending DPF work away or telling customers to visit the dealer. Bringing it in-house captures work you are already touching — no new customer acquisition, faster turnaround, and a margin you keep instead of pass on.
Diesel aggregate & reman centres
Turbo, injector and EGR specialists have a natural advantage: a failed turbo floods the DOC and DPF with oil, so the filter needs cleaning as part of the same job. Offering both in one place turns two visits into one invoice.
Transport & fleet companies
Fleet owners buy the machine to stop paying for cleaning or replacement on their own vehicles — then discover the spare capacity is worth money. Cleaning for neighbouring workshops turns a cost centre into a revenue line.
Dedicated DPF service points
A standalone centre serving other garages rather than end customers. Local workshops send filters to you, fleets book batches, and couriers extend your reach well beyond your own city. This is how the network grows fastest.
What One Filter Actually Earns You
Revenue is the easy half. What matters is what survives after the solvent, the labour and the power — so both halves are here.
| Per job | Car & SCV DPF | Truck DPF | DOC / SCR |
|---|---|---|---|
| What you charge | ₹4,000–₹8,000 | Higher — quoted per assembly | Quoted per assembly |
| Cycle time | About 150 minutes | Longer | Longer |
| Who sends it | Walk-ins, garages, taxi fleets | Truck garages, fleets, OEM dealers | Fleets, reman centres |
Volume, Honestly
What comes out of the revenue
The setup checklist
Nothing exotic. Most workshops already have three quarters of this — but check all of it before you order a machine, not after.
- Around 400 sq ft is enough — machine, soak tank, filter handling and a customer area
- Covered, ventilated space with a solid floor
- Drainage point for the machine's water handling
- Somewhere lockable to store solvent safely
- No dedicated bay needed — the machine does not occupy a vehicle lift
- Three-phase power connection [confirm kW load per model]
- Water supply — recycled inside the machine, so it is refill rather than continuous
- Compressed air [confirm CFM and pressure]
- Earthing and a dedicated MCB for the machine
- Ventilation where solvent is handled
- Firm or company registration, and GST
- Municipal trade license / Shop & Establishment registration
- State Pollution Control Board consent — used solvent and sludge are regulated waste
- A tie-up with an authorized waste disposal vendor
- Fire safety and PPE compliance for the working area
Requirements vary by state and municipality. Confirm locally — we help partners prepare the documentation, but we are not your legal advisor.
- One technician to train on the machine and the SOP
- A service advisor who can explain cleaning versus replacement
- ₹7.5 lakh (Pro / Plus) or ₹11.5 lakh (Supreme), plus GST
- Working capital for solvent refills and the first months of marketing
- Equipment finance from a bank or NBFC if you would rather not pay up front
You do not need to already know DPFs
Almost nobody entering this business does — there is no established trade to have learned it from. Training covers the theory, the machine and the customer conversation, on real filters rather than slides.
The hardest part is not operating the machine. It is diagnosing correctly, knowing when a filter cannot be saved, and explaining both to a customer who has just been quoted ₹80,000 by a dealer.
How a DPF works, and why it fails
Filter construction, regeneration, and the four contamination types — soot, ash, fuel residue and oil films.
Diagnosis & measurement
Scan tools, fault codes, backpressure readings, and judging whether a core is recoverable before you quote.
Removal, machine operation & refitting
Hands-on cycles on real filters, plus safe removal without damaging sensors, clamps and gaskets.
Safety, PPE and waste handling
Solvent handling, compressed air safety, and how sludge and used solvent are disposed of legally.
Documentation & job cards
What goes on the worksheet, and how before/after readings become your proof and your marketing.
Selling the job
Explaining cleaning versus replacement honestly, quoting, and handling the customer who wants a delete instead.
Six things that win repeat work
Garages and fleets are not comparing your machine. They are comparing how easy you are to deal with.
Pickup & delivery
Collecting the filter from the garage removes the single biggest reason they will not send you work.
Same-day turnaround
The vehicle is on a lift while the filter is with you. Speed is worth more than a discount.
A printed job report
Before and after readings, in writing. Fleets need it for their records and garages use it to justify the bill.
An honest diagnosis
Telling a customer their core is cracked and cleaning will not help earns you the next ten jobs.
Courier acceptance
Filters arriving by courier from other cities extend your market far past your own locality.
Trade rates & a warranty
Regular garages want a standing price and a stated warranty, not a fresh negotiation every filter.
Non-thermal, solvent-based, measured
Heat-based machines risk cracking the ceramic substrate. Water-only flushing moves soot and leaves ash. Our cycle does neither.
Garages first
Visit the multi-brand workshops around you. They already see clogged filters and have nowhere to send them. Trade work fills a machine faster than walk-ins ever will.
Fleets & taxi operators
One taxi fleet or transport company can steady an entire month. Offer a free health check on two vehicles and let the readings do the talking.
Your Google listing
A verified Google Business Profile with real photos and reviews is what wins "DPF cleaning near me" locally. It costs nothing and outranks a website for local searches.
Before/after proof
Photograph every filter and keep the readings. A WhatsApp message showing 210 mbar dropping to 30 sells better than any brochure.
Pickup & courier
Collect filters from garages, and accept couriered filters from other cities. This is how a single centre serves a whole region.
Pick the machine that matches your traffic
Buy for the vehicles already coming through your gate, not for the ones you hope will arrive.
