Top 7 China Filtration Equipment Companies 2025
China's filtration equipment industry, valued at approximately CNY 120 billion, spans air filtration (HVAC, cleanrooms, industrial dust collection), liquid filtration (water treatment, pharmaceutical, food and beverage), and specialized filtration for semiconductor and medical applications. Rapid growth in semiconductor fab construction, pharmaceutical cleanrooms, and data center HVAC systems has driven strong demand for high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters. Environmental regulations on industrial emissions continue to expand the market for baghouse filters and cartridge dust collectors.

Frequently Asked Questions
What is driving growth in China's filtration equipment market?
Three main drivers: semiconductor fab construction requiring ULPA filters, pharmaceutical cleanroom expansion requiring HEPA filters, and stricter industrial emission regulations requiring baghouse dust collectors. Data center cooling is an emerging driver for specialized AHU filters.
Which Chinese companies supply filters for semiconductor fabs?
Nanjing Blue Sky Filter is the dominant domestic supplier of HEPA and ULPA filters for semiconductor cleanrooms in China. Their products meet EN 1822 H13-U17 standards and are installed in SMIC, Hua Hong, and Nexchip fabrication facilities.
How are Chinese filtration companies addressing sustainability?
Companies are developing washable and reusable filter media to reduce waste, energy-efficient filter designs that lower HVAC fan power consumption by 20-30%, and bio-based filter media from PLA and cellulose fibers. Blue Sky Filter has introduced recyclable aluminum frame HEPA units.
What filtration standards do Chinese manufacturers follow?
Leading manufacturers comply with EN 1822 (HEPA/ULPA), EN 779 (general ventilation), ASHRAE 52.2 (MERV rating), and GB/T 14295 (Chinese air filter standards). Nantong Environmental follows GB 16297 emission standards for industrial dust collection.
What is the outlook for China's filtration market?
China's filtration market is expected to grow at 10% CAGR through 2030, reaching CNY 200 billion. Semiconductor and data center applications will be the fastest-growing segments, while industrial dust collection will benefit from carbon neutrality policies driving cement and steel plant upgrades.
