How to Clean the Diesel Exhaust Filters of Your Vehicle

DPFs or diesel particulate filters are straining devices frequently put in the exhaust flow pipe of a vehicle. Putting this on in the exhaust meets the norms set by the Environmental Protection Agency to take care of our environment most especially the air we breathe all the time. DPFs, moreover, are often times disposable as to easily get rid of them once they became almost clogged with particulates. However, there are those who are actually reusable which clean themselves (passive DPF) or can be cleaned easily (active DPF). So if you have the reusable DPF, how do you do the sprucing up of your device?

  1. Always consult the user’s (or owner’s) manual that came along upon the purchase of your vehicle. You can learn what type of DPF that is actually used for your automobile. As mentioned before, passive DPFs clean themselves, but if you have the active one, you must learn about cleaning them. Remember as well that clogged DPF will make poor performance for your vehicle.

(Note: If you’re not confident in cleaning your DPF for the first time, consult professional help service.)


  1. Confirm that the DPF warning light is on by checking on your vehicle’s dashboard. Apparently, you need to heat up your exhaust gas to burn up particulates in your DPF. On the other hand, slow-speed driving won’t burn those particulates; thus, clogged filters occur.


  1. For quick and simple cleaning, just step on the gas and zoom your vehicle to the highways or roadways allowing high speed. Reach for the 40mph speed and maintain it for about 10 minutes. This will enable to raise temperature on the exhaust and will help burn particulates within the DPF. Monitor the warning light until it turns off which means that your DPF is cleansed already.
