Everything we do to a
diesel after-treatment system.

Passenger cars and SUVs typically start from ₹8,500, light commercial vehicles from ₹12,000, and heavy commercial or off-highway equipment from ₹18,000 depending on filter size and condition. The exact figure depends on the vehicle, the degree of ash loading and whether any upstream faults need correcting. For context, a replacement DPF commonly costs between ₹80,000 and ₹4,00,000: cleaning is usually a small fraction of that.

Substantially. Cleaning typically costs between 5% and 15% of a replacement filter. Replacement is genuinely necessary only where the substrate is physically damaged, cracked, melted or collapsed, which is a small minority of the filters we see. Our diagnostic pass establishes which case applies before you commit to anything, and we will tell you plainly if a filter is not worth cleaning.

Most passenger car and light commercial filters are completed within a single working day, typically four to eight hours from the filter reaching us to it being ready for collection. Heavy commercial and off-highway filters may take longer depending on size. Note that we clean the filter itself: it comes to us already removed, and goes back to your own workshop to be refitted. Fleet customers on contract can use our loan filter pool, so a cleaned filter is available to go on as yours comes off, which keeps the vehicle earning while its own filter is here.

Yes, where the performance loss was caused by exhaust restriction, which it usually is. A blocked filter raises back pressure, which directly reduces power and increases fuel consumption. Our flow bench testing regularly shows restoration to within 95–99% of original flow, and the corresponding recovery in power, throttle response and fuel economy is immediate and measurable. What cleaning cannot fix is a performance problem with a different root cause, which is precisely why we diagnose before we clean.
