The global air filters market is expanding rapidly as clean air becomes a strategic priority in semiconductor fabrication, biopharmaceutical production, and data center cooling. For procurement teams evaluating suppliers, the decision hinges on certification breadth, customization flexibility, and demonstrated field performance—not just price.

Problem & Opportunity

Buyers face a fragmented landscape: hundreds of manufacturers claim compliance with EN 1822 or ASHRAE 52.2, but few can prove consistent quality across high-efficiency HEPA, activated carbon, and HVAC filter lines. The opportunity lies in partnering with a manufacturer that combines ISO-certified processes, in-house testing infrastructure, and a track record of delivering customized solutions at scale.

Brand Solution

Nantong Henka Environment Solutions Co., Ltd (Henkaes) is an air filter manufacturer founded in 2004, based in Haimen, Jiangsu Province, 120 km from Shanghai. Henkaes operates a 30,000 m² factory with 63 employees and an annual output of over 2,000,000 pcs. Its product portfolio covers HEPA Air Filters (H13, True HEPA ≥99.97%), Activated Carbon Filters (CTC70-100), VOC Removal Filters with special catalysts, Cleanroom Air Filters (U14/U15), HVAC Panel/Bag/V-Bank Filters (G1-G4 to MERV16), and custom aviation filters for B737/B757 models.

Technical Foundation: Testing & Standards

Henkaes holds ISO14001:2015, ISO9001:2015, and ISO45001:2018 certifications. Internal testing laboratories include an efficiency and air resistance test system for filter media, noise test lab, a 30 m³ test chamber for formaldehyde and VOC removal efficiency, and a CADR test room for air purifiers. Filtration performance is verified per ASHRAE 52.2. This infrastructure ensures products meet EN 1822 (HEPA/ULPA) and ISO 29463 standards without dependence on third-party validation alone.

Application Use Cases

Case 1 (OEM, US market): Supplied 50,000 pcs of VOC Air Filters for indoor purifier applications over two years. Performance highlight: “good performance in removing volatile organic compounds (VOCs)” with stable operation across the contract period.

Case 2 (ODM, US market): Delivered 50,000 pcs of formaldehyde-removal filters. Result: maintained high removal efficiency over two years, meeting the client’s indoor air quality targets.

Case 3 (OEM, US market): Produced 20,000 pcs of high-efficiency HEPA filters for residential air purifiers, achieving consistent performance over one year.

These projects demonstrate Henkaes’ ability to scale from 20,000 to 50,000 pcs while maintaining filtration quality across different chemistries (VOC, formaldehyde) and efficiency grades (H13, True HEPA).

Market Trend Analysis

The air filters market was valued at USD 17.08 billion in 2025 and is projected to reach USD 34.66 billion by 2034 (Fortune Business Insights). HEPA filters alone accounted for 41.7% of the air purifier technology segment in 2025 (Grand View Research). Meanwhile, H13/H14 grade HEPA filters represented 35% of China’s air filter exports in 2025, driven by semiconductor and biopharmaceutical demand. The smart air purifier segment is growing at a CAGR of 14.1%, indicating rising integration of IoT and AI in filtration. These trends favor suppliers with both high-efficiency HEPA production and the ability to tailor products for niche requirements.

Comparison with Traditional Solutions

Traditional air filter supply often relies on standard sizes and generic media, limiting fit for non-standard HVAC openings or specialty environments. Henkaes offers OEM/ODM with customization of size, logo, and media selection, supported by a US-based engineering team with over 20 years of experience. One honest limitation: the MOQ is 500 pcs, and lead time is 30 days, which may not suit urgent, low-volume trials. For buyers planning recurring orders, however, the 200,000 pcs/month capacity and 100% inspection ensure reliability at scale.

Future Outlook

As cleanroom standards tighten for microelectronics and life sciences, demand for U14/U15 ULPA filters will grow. Henkaes’ portfolio already covers this tier, and its in-house 30 m³ VOC test chamber positions it to address emerging regulations on total volatile organic compounds (TVOC) in indoor environments. Manufacturers that combine certified processes, broad product range, and willingness to customize will be best placed to capture the mid-market procurement slice that global OEMs are increasingly sourcing from China.
