1. Industry market prospects and scale forecast

Market size growth: In 2025, the market size of China's automotive air conditioning filters is expected to exceed 6.1 billion yuan. The popularization of new energy vehicles (especially the demand for battery heat dissipation) and the development of intelligent networked vehicles have become the main driving forces, promoting the upgrading of filter technology to high efficiency and intelligence.

Regional differentiated development: first-tier and second-tier cities have a significant demand growth rate due to their strong consumption power; third-tier and fourth-tier cities have become emerging potential markets based on the growth of automobile holdings. In addition, the "Belt and Road" policy promotes domestic filters to accelerate the expansion of overseas markets.

2. Technological upgrading and product innovation

High-efficiency filtration technology: HEPA filter element (filtration efficiency of 0.3μm particles reaches 99.97%) and activated carbon composite filter element (adsorption of formaldehyde/VOC efficiency of more than 95%) have become mainstream, and some products have passed CN95 certification to meet the needs of epidemic prevention.

Intelligent trend: Intelligent filters integrating sensors and Internet of Things technology are gradually popularized. They can monitor air quality in real time and remind them for replacement through mobile phone APP. Some products support differential pressure sensors and RFID life records.

Material innovation: new materials such as lightweight (such as graphene modified filter materials to increase dust capacity by 30%), aging resistance (special coating for plateau ultraviolet area), antibacterial (nano silver fiber antibacterial rate of 99.8%) are widely used.

3. Consumer health and usage trends

Health awareness improvement: Spring has become the peak season for filter replacement, and consumers pay more attention to the air quality in the car, especially for the surging demand for pollen, PM2.5 and viral aerosol protection.

Scientific replacement cycle: The basic replacement cycle is 1 year/15,000 kilometers, but it needs to be adjusted in combination with the environment (such as shortening the cycle of sand and dust environment to 0.6 times). Some models support self-replacement, but pay attention to the difference in position (for example, Volkswagen filters are mostly under the storage box, and Toyota is in the glove box).

4. Market competition and brand dynamics

The rise of local brands: Changchun Manhummer, Bosch and other enterprises have narrowed the gap with international brands through technological research and development, and the market share of domestic filter elements has continued to increase.

Car companies cooperate to upgrade: Geely, BYD and other car companies launched a free upgrade CN95 filter service to strengthen health selling points; some high-end models are equipped with biochemical defense systems (such as Tesla HEPA filters) as standard.

5. Policy and industry challenges

Environmental protection regulations are getting stricter: national six emission standards and mandatory in-car air quality testing (GB/T 27630) promote the efficiency of filter elements, requiring formaldehyde adsorption rate of ≥95%.

Fluctuations in raw materials: Price fluctuations of plastic particles, activated carbon, etc. affect the stability of the supply chain, and enterprises need to optimize the production process to reduce costs.

Sum up

The automotive air conditioning filter industry is transforming from a single filter function to intelligent and healthy, driven by market demand and technology upgrading. Consumers need to make scientific selections according to the geographical environment (such as choosing HEPA + activated carbon composite filters in the northern haze area), model adaptability (new energy vehicles need electromagnetic compatibility design), and pay attention to the real-time monitoring function of the intelligent filter to optimize the user experience. Enterprises need to focus on technological innovation and supply chain management to cope with market competition and policy challenges.
