[Racing Air Filter]
An air filter is a device which removes solid particulates such as dust, pollen, mold, and bacteria from air.
Air filters are used in applications where air quality is important, notably in building ventilation systems and in engines,
such as internal combustion engines, gas compressors, diving air compressors, gas turbines and others.
The cabin air filter is typically a pleated-paper filter that is placed in the outside-air intake for the vehicle's passenger compartment. Some of these filters are rectangular and similar in shape to the combustion air filter. Others are uniquely shaped to fit the available space of particular vehicles' outside-air intakes. Being a relatively recent addition to automobile equipment, this filter is often overlooked[citation needed]. Clogged or dirty cabin air filters can significantly reduce airflow from the cabin vents, as well as introduce allergens into the cabin air stream.
