How Car Filters Work

All filters incorporate a filtering device constructed from various materials. These materials can vary from cloth fibers, paper fiber and wire mesh screens or any combination of the three. Most fuel and oil filters are housed within a metal container connected to the engine or fuel system. Most vehicles have one or more filters that require regular maintenance (replacement). These filters range from a air filter, fuel filter, air cabin filter and oil filter. A properly maintained filter system will enhance the performance and extend the life of vehicle. Air filters remove debris from the air before it is allowed into the engine. If dirt where allowed to enter the engine it would cause premature failure.
