Global Automotive Air Filter Market accounted for US$ 5.08 billion in 2020 and is estimated to be US$ 5.90 billion by 2030 and is anticipated to register a CAGR of 1.5%. The air filter keeps insects, dust, particles, sand, and debris out of the engine, as well as ensuring a good air-fuel mixture for optimal performance. Air filters for automobiles are available in a variety of designs, including panels, circular filters, and cylindrical filters. They're made of cotton, synthetic paper, or foam pleated material that filters the air. Before reaching the air to combustion chamber of the engine, it must pass through a filter to avoid other particles in the air that are damaging to the engine or fuel combustion. The air filters play a crucial function in preventing engine damage and improving engine performance by filtering the air before it enters the engine.
