The performance of an automobile is bolstered significantly by the presence of high performance filter media in the engine compartment and in various other locations. The ultimate goal is to balance filtration performance with the desired cleanliness level. The media in a filter is the physical mechanism used for contamination control. Media construction and filter configuration are used to determine the filter's efficiency for particle removal, its contaminant capacity and the pressure drop through the filter. By working with these variables - efficiency, capacity, pressure drop - the filter's performance level can be determined. The filter media ranges from mesh screens to depth style media such as threads or chopped paper to 100 % natural cellulose to 100 % man-made fibres to almost any conceivable combination in between. With so many media choices, it becomes a complex aspect to choose a right kind of media for an engine system. From this point of view the authors discuss the various aspects of air, oil, fuel, and cabin filter construction, filter performance and related developments. Over the past decade significant attention is being paid in designing and development of air filters, oil filters, fuel filters and cabin filters. Many new designs differing in construction and raw material have come up and are continuously evolving. Presently nano-fibre filter media has been successfully used in a variety of filtration applications mainly due to their low density, large surface area to mass, high pore volume and tight pore size.
