Why do I need a DPF anyway?
Diesel Particulate Filters (DPFs) are used to reduce the amount of particulate matter (soot) released from the exhaust of a diesel vehicle. They are usually fitted to vehicles in order to meet required emissions regulations such as the European Emission Standards (Euro limits). Reducing these emissions is important because they are very damaging for people’s health, particularly in the concentrations found in many urban areas. The World Health Organisation (WHO) has listed both diesel exhaust in general, and particulates specifically, as carcinogenic. In addition to increasing the risks of cancer, particulates are also believed to worsen asthma, other respiratory problems and cardiovascular disease.
