Key Takeaways:
Overview: Glass fiber air filter paper is a filter medium made primarily of glass fiber using a wet-laid process. Compared with other filter materials such as animal and plant fibers, synthetic fibers, and activated carbon, it features large dust holding capacity, high filtration efficiency, and uniform fiber distribution, making it an ideal clean air filtration material.
Upstream of the industrial chain: Microfiber glass wool is the main raw material for glass fiber air filter paper, and its characteristics have a decisive influence on the performance of the filter paper. Microfiber glass wool is flocculent and loosely structured, resulting in filter paper with high porosity and uniform fiber distribution, ensuring high filtration efficiency while maintaining low air resistance. In recent years, my country's microfiber glass wool production has increased, from 150,700 tons in 2018 to 222,000 tons in 2024, with a compound annual growth rate of 6.7%. With the increase in microfiber glass wool production, the raw materials for glass fiber air filter paper will be secured.
Market size: China's glass fiber air filter paper industry started in the mid-1990s and, after decades of development, has formed a certain industrial scale. In recent years, with the increasing attention to air quality and the increasingly serious air pollution problems brought about by the accelerated industrialization process, the market demand for glass fiber air filter paper has shown a continuous growth trend. At the same time, the development of emerging fields such as new energy vehicles and smart homes has also provided new market opportunities for the glass fiber air filter paper industry. In terms of technological progress, China's glass fiber air filter paper industry is also constantly innovating and improving its processes.
