The terms diesel emmission filter and diesel emission filter are both being used in the search engines when people are in search of this topic. While not everyone can be a great speller, every diesel powered vehicle can have their emissions reduced with the use of the diesel particulate filter (DPF).

This device was developed for the sole purpose of reducing the amount of solid material from reaching the end of the exhaust system on a diesel powered vehicle. This solid material is in the form of soot and other fine particles that are suspended in the exhaust gases when it leaves the combustion chamber of the engine.

At this time, there are two different styles of DPF in service on the fleets of diesel powered trucks that are roaming the highways. There is the disposable, and the passive regenerative filters. Both types are being manufactured to produce certified particulate reducing filters that are being retrofitted onto existing diesel powered trucks to help them meet the new EPA emissions standards.

The disposable DPF does require replacement after a set time or it will become clogged and no longer remove the particulates it was designed to trap. The passive regenerative DPF has a catalyst in its honeycomb chambers that converts the harmful particulates into non-hazardous material that also must be periodically cleaned out. On average, this cleaning period is every 6 months.

With most devices of this kind, the reduction in particulates from reaching the end of the tail pipe is between 85% and 100%. This amount of reduction can visibly be seen by those on the roads today. No longer does every diesel powered truck emit a large black puff of smoke each time their accelerator pedal is pushed.

Cleaning up the air we breathe is the only job of the diesel emission filter. No matter what the spelling, these filters give us cleaner air.
