The automotive filter market size is expected to advance at a CAGR of 3.4% during 2024–2030, to reach $15.5 billion by 2030. This is ascribed to the rising concern regarding environmental pollution, global warming, and respiratory diseases, which has forced government to implement stringent emission norms.
Automobiles are a major cause of atmospheric pollution, especially in metropolitan cities. Poorly designed and maintained automobiles are a major cause of air pollution. They release of black smoke due to incomplete or improper fuel combustion in the engine, an inappropriate air–fuel mixture, or the use of low-quality fuel. As a result of the increasing number of vehicles on the roads, combined with these factors, air pollution levels are increasing day by day.
Therefore, emission norms are crucial as they help ensure environmental sustainability and public health and safety by controlling the amount of pollutants released by vehicles. For instance, new automobile emission rules became effective in India in April 2023. The government has imposed Real Driving Emission (RDE) norms, which are even stricter than the present Bharat Stage 6 standards. According to the new standards, automakers must provide RDE data for each of their vehicles.
Similarly, the United States Environmental Protection Agency has proposed to amend the CAFE and other GHG emission standards for cars and light commercial vehicles for model years (MY) 2023 through 2026.
The filter’s medium is crucial to both its efficiency and the ability of the engine to function properly and reliably. This is because it essentially captures hard particles, which can cause several problems in the fuel system. In addition to this, these contaminants can damage the moving parts and, further, lead to starting problems, such as poor engine performance, idling issues, and, potentially, complete engine failure.
Cellulose, synthetic, glass fiber, and activated carbon are used as the filtration medium, depending on the application. The cabin filters currently available can stop up to 99% of the particles 1–3 microns in size and all the particles measuring 3 microns or more from entering the engine. Further improvements in their materials or technology may offer a tremendous business growth potential for the makers of automobile filters.
With the increasing disposable income of customers and their simultaneously rising preference for high levels of comfort and safety, luxury car sales continue to boom. These cars often feature high-performance engines with advanced technologies, which produce higher power outputs and more-complex exhaust emissions. As a result, there is a greater need for efficient filtration systems to meet emission standards and ensure optimal engine performance. Moreover, these vehicles are equipped with advanced infotainment systems, electronic controls, and safety systems, which require filtered air to prevent damage by dust.
Globally, Asia-Pacific holds the largest share in the market in 2023, because automotive OEMs are investing in new technologies to increase vehicle production. In addition, the rising urbanization rate and increasing environmental pollution level will drive the demand for these filters during the forecast period. Additionally, India is fourth-largest automotive producer with an output of 5,456,857, as per OICA. Some of the most-well-known automotive brands based in the region are Maruti Suzuki, Honda, Hyundai, Tata Motors, Mahindra & Mahindra, Kia, and Toyota.
Furthermore, the increasing spending on infrastructure projects and the rising e-commerce activities in developing countries, such as India and China, are likely to propel the demand for commercial vehicles. Air filters are essential to their performance as these vehicles often operate on tough terrains, in adverse weather, and under heavy loads.
The most-significant automotive filter market players are DENSO Corporation, MAHLE GmbH, Robert Bosch GmbH, K&N Engineering, Inc., Sogefi Group, MANN+HUMMEL International GmbH & Co. KG, Hengst SE, Parker-Hannifin Corporation, Hollingsworth & Vose, and Ahlstrom.
