DPF filters are used to remove particulate matter from the exhaust gas of diesel engines. Particulate matter is any solid or liquid substance that is suspended in the air. The most common type of particulate matter is soot, which is made up of carbon particles that are released when diesel fuel is burned.
DPF filters are designed to capture and retain particulate matter, preventing it from being released into the atmosphere. In order to work properly, DPF filters must be regularly cleaned or replaced. The most cost effective way to replace them is with aftermarket parts.
