The reduction of traditional filters: Electric vehicles (EVs) no longer use internal combustion engines, so the demand for fuel filters and oil filters will gradually decline as the trend of internal combustion engine vehicles recedes.
The demand for cabin air filters is on the rise: EVs are paying more attention to the air quality inside the vehicle, and the demand for high-efficiency HEPA/ activated carbon/antibacterial and antiviral filters in passenger cars is growing rapidly.
The rise of thermal management system filters: The demand for liquid filters in EV battery cooling systems is forming a new growth point.
Prediction: By 2030, the proportion of electric vehicles may exceed 50% (even higher in China), the traditional filter market will gradually shrink, and cabin and dedicated thermal management filters will become the main force
Emission standards in Europe, the United States, Japan, China and other regions have been continuously tightened (such as Euro 7 and China's National VII), which has forced the precision, heat resistance and lifespan of engine filters to improve.
The improvement of air quality standards (with stricter limits on PM2.5, VOC and NOx) has led to the wide application of anti-haze, formaldehyde removal and antibacterial filter materials in vehicles.
Development trend: From traditional paper-based filter materials → composite polymers, nanofibers, electrostatically charged materials → intelligent self-cleaning systems
In the future, filters will no longer be "purely passive components", but will develop towards "intelligent monitoring + life management".
For instance, the air filter element is equipped with a built-in sensor that can determine the degree of clogging, remind for replacement, and even automatically adjust the air conditioning system.
Commercial vehicles, engineering vehicles and high-end models are gradually piloting such "intelligent filtration systems".
Enterprises attach great importance to "carbon neutrality + circular economy" : using renewable materials (such as PLA biodegradable materials) to manufacture filter elements;
Introduce a recyclable structural design and encourage modular replacement (only replace the filter element, not the housing);
Develop a "water-washable and reusable" filtration system to reduce the frequency of replacement and the amount of discarded filter elements.
As the world's largest automotive market, China has over 400 million vehicles in use (by 2025), and its replacement market is extremely large.
Policy guidance, a complete local supply chain, and global leadership in electrification have enabled China to gradually shift from manufacturing to technological leadership in the field of filters.
Many domestic brands (such as Dongfeng Filter, Wanli Road, Sofima China, and Man China) are accelerating the high-endization and internationalization of their products.
Qinghe County Dongsen Auto Parts Co., Ltd. is located in Qinghe County, Xingtai City, Hebei Province. It was established in 2024. Although the company was established a short time ago, it has more than 10 years of production experience. We are a manufacturer specializing in the production of air filters, air conditioning filters and oil filters. The filters produced by our factory serve the domestic and foreign markets and have won unanimous praise from customers in Southeast Asia, Africa, South America and other regions.
