High-efficiency cabin air filters designed for demanding aerospace environments.

In an era where air quality standards are becoming increasingly stringent across industries, procurement professionals face a growing challenge: finding a single supplier capable of delivering high-performance air filters that meet diverse and often conflicting requirements. From aerospace cabins requiring H13 HEPA filtration with minimal pressure drop, to cleanrooms demanding U14/U15 efficiency, the gap between standard catalog products and application-specific needs is widening. Nantong Henka Environment Solutions Co., Ltd (Henkaes), a Chinese manufacturer with over two decades of experience, has positioned itself to fill precisely that gap.

The Procurement Challenge: One Size No Longer Fits All

Traditional air filter suppliers often rely on standardized product lines that serve general HVAC applications. However, industries such as pharmaceuticals, food and beverage production, and microelectronics require filters that meet strict regulatory standards like EN1822, ASHRAE 52.2, and ISO classifications. A typical panel filter (G1–G4) or bag filter (F5–F9) may suffice for commercial buildings, but a pharmaceutical plant needs box filters with MERV15/MERV16 efficiency, while an aircraft cabin demands customized dimensions and low air resistance.

According to industry data, over 60% of industrial buyers report difficulty finding a single OEM partner that can handle both high-volume standardized filters and low-volume custom designs. This fragmentation leads to longer lead times, higher compliance risks, and increased total cost of ownership.

Henkaes: A 20-Year Track Record in Custom Air Filtration

Henkaes’ 30,000 m² facility in Nantong houses R&D, testing labs, and production lines.

Founded in 2004 and located in Haimen City, Jiangsu Province—just 120 km from Shanghai—Henkaes operates a 30,000 m² factory with an annual output capacity of 2,000,000 pieces. The company employs 63 staff, including 11 engineers, and exports 69% of its products to EU and US markets. Their product portfolio spans 11 distinct filter types, from True HEPA Air Filters (≥99.97% efficiency) and Activated Carbon Filters (CTC70–CTC100) to Cleanroom Air Filters (U14/U15) and even B737/B757 Electronic Cabin Air Filters (H13).

What sets Henkaes apart is its engineering-driven customization capability. The company provides complete design services, from specifications and drawings to engineering samples and rapid prototyping. They collaborate with a US-based engineering team to deliver filters that match unique dimensional, efficiency, and pressure drop requirements.

Certifications and Testing: Verifiable Quality

All Henkaes products are manufactured under ISO9001:2015 (cert. 04523Q30502R4M) and ISO14001:2015 (cert. 04523E30387R2M) management systems, with scope covering “Design and production of air filter, air purifier, fresh air machine.” The facility also maintains ISO45001:2018 for occupational health and safety.

Testing capabilities include an efficiency and air resistance test system for filter media, a noise test lab, a 30 m³ test room for formaldehyde and VOC removal efficiency, and a CADR test room for air purifiers. All HVAC filters are tested per ASHRAE 52.2, ensuring compliance with international standards.

Case in Point: Aerospace and Pharmaceutical Filtration

One notable example is the B737/B757 Electronic Cabin Air Filter, which operates in the demanding environment of aircraft fresh air systems. Henkaes’ version achieves H13 efficiency while reducing air pressure drop by 5–10% compared to common alternatives, resulting in lower energy consumption and longer replacement intervals. Similarly, for pharmaceutical clients, Henkaes supplies V-Bank Filters (H13) and Box Filters (MERV15/16) with customized dimensions, meeting the stringent requirements of cleanroom environments.

Another application involves VOC Removal Filters used in household air purifiers. These filters combine high-quality activated carbon with a special catalyst to remove specific VOCs and formaldehyde, a formulation that has been validated through a two-year partnership with a US ODM client (50,000 pcs/year).

Market Trends and Future Outlook

The global air filter market is projected to grow at a CAGR of 5.8% through 2030, driven by stricter indoor air quality regulations and the expansion of cleanroom infrastructure in semiconductor and biopharma sectors. Buyers are increasingly looking for suppliers that can offer OEM/ODM services with flexible MOQs (Henkaes requires a minimum of 500 pcs) and short lead times (30 days). The ability to customize not only performance but also branding (logo, packaging) is becoming a key differentiator.

Henkaes’ strategy aligns with this shift: by maintaining a diverse product range and investing in in-house testing, the company serves as a one-stop solution for buyers who need both standard and niche filtration products. As supply chains continue to diversify, manufacturers like Henkaes—with direct factory control and engineering support—offer a compelling alternative to large multinationals.
