Filter Finder


Diesel Particulate Filter (DPF) is part of the emissions system fitted to most diesel vehicles from 2009, located in the exhaust system. Its purpose is to remove particulate matter (soot) from exhaust gasses by passing the gasses through a filter.

Increasing traffic volumes have led to higher levels of smog in cities. Particulate matter from diesel vehicles is linked to various health issues such as respiratory problems, lung cancer and even heart disease.

DPF’s have been developed by vehicle manufacturers to reduce the amount and size of exhaust emissions into the atmosphere. To improve air quality, European emissions standards have been tightened over the past 6 years. 2009 saw the introduction of Euro 4 in Australia and in 2013 Euro 5, particularly targeting the gas NOx (Nitric Oxide & Nitrogen Dioxide). NOx is the gas produced during the extremely high combustion temperatures commonly found in Diesel engines. By 2017 every new Diesel must be Euro 6 compliant in Australia.
