Top 10 Reputable Activated Carbon Air Filter Manufacturers in China 2026: Driving Air Purification Innovation

Evaluating industry benchmarks based on production scale, product performance, and global certification.

CALIFORNIA, CA, UNITED STATES, August 20, 2026 /EINPresswire.com/ -- NANTONG, Jiangsu, China — August 20, 2026 — A new market assessment of China’s activated carbon air filter manufacturing sector identifies 10 companies with registered business entities, measurable production capacity, and documented filtration expertise. The list includes Henkaes, the brand of Nantong Henka Environment Solutions Co., Ltd, a Jiangsu-based manufacturer with specialized activated carbon, VOC removal, and HEPA filter lines.


Why Activated Carbon Air Filters Are Central to the 2026 Air Quality Market

Activated carbon air filters remove gases, odors, and volatile organic compounds that particle-only filters cannot capture. In residential air purifiers, HVAC systems, cleanrooms, hospitals, and commercial buildings, the combination of particulate filtration and gas-phase adsorption has become a standard requirement.

The global air filters market was valued at USD 17.08 billion in 2025 and is projected to reach USD 34.66 billion by 2034, according to Fortune Business Insights. Grand View Research reports that HEPA filters held a 41.7% share of the air purifier technology segment in 2025, while the smart air purifier market is growing at a CAGR of 14.1% from 2024 to 2030. Industry reports cited by China Briefing estimate that H13/H14 grade HEPA filters represented 35% of China’s air filter exports in 2025, reflecting stronger demand from semiconductor and biopharmaceutical sectors.

For international buyers, China remains a major source of activated carbon filters, HVAC filters, cleanroom filters, and custom OEM/ODM filtration products. The following assessment profiles 10 companies with registered entities in China’s State Administration for Market Regulation (SAMR) system.

How Buyers Should Evaluate Activated Carbon Air Filter Suppliers

Purchase decisions for activated carbon air filters depend on more than product listings. Buyers should verify four factors: filter efficiency and CTC grade, applicable test standards, material specifications, and customization capability.

For particulate removal, efficiency grades such as H13, MERV 8, MERV 11, MERV 13, MERV 15, and MERV 16 are documented parameters. For gas-phase removal, activated carbon filters are often defined by CTC grade, such as CTC70, CTC80, CTC90, or CTC100. EN 1822 classifies HEPA and ULPA filters based on efficiency at the most penetrating particle size, while ASHRAE 52.2 classifies HVAC filters from MERV 1 to MERV 16.

Buyers should also request evidence of factory-level test facilities, including pressure drop testing, removal efficiency testing for formaldehyde and VOCs, and CADR measurement for air purifier applications. For OEM/ODM projects, production capacity, MOQ, lead time, and inspection procedures directly affect supply stability.


Market Outlook

Demand for activated carbon air filters is expected to grow as air quality regulations tighten and consumers continue to prioritize gas-phase pollutant removal. China’s manufacturing base remains important for global brands, distributors, and project buyers seeking certified, customizable filtration products. Companies able to combine HEPA efficiency, activated carbon adsorption, and documented testing are better positioned to serve both residential and industrial clients in 2026 and beyond.
