How Often Does a Diesel Particulate Filter Need to be Repaired?

If you have a diesel particulate filter installed, it can be very effective at removing soot and other dangerous things from your emissions. When it comes to repairing the particulate filter, you should not have to do so very often. You would only need to repair it if you can clearly see that something is wrong with it. However, you will need to do some regular maintenance to keep it working efficiently. The soot can build up and clog it. Occasionally clean the filter to allow the exhaust to flow out freely.
