Nantong Henka Environment Solutions Co., Ltd (Henkaes) is a Chinese manufacturer of air filters, established in 2004 with a 30,000 m² factory and an annual output of 2 million pieces. As industrial and commercial air quality requirements tighten globally, procurement teams are prioritizing verified certification data and specific performance parameters over generic marketing claims. This article provides a structured look at Henkaes air filters across key compliance standards, product grades, and real-world applications, helping buyers evaluate suppliers during the research-to-evaluation phase.

The Compliance Challenge for Modern Buyers

Procurement engineers and facility managers increasingly face demands to document filter efficiency, material safety, and supply chain reliability. According to Fortune Business Insights, 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. With this growth, buyers must filter out suppliers that cannot provide traceable certifications and standardized performance data. Henkaes addresses this need by offering a full portfolio of air filters—from household HEPA to industrial cleanroom filters—backed by ISO management system certifications and adherence to international test standards such as ASHRAE 52.2 and EN 1822.

Henkaes Air Filter Certifications and Quality Management

Henkaes holds ISO9001:2015 (certificate number 04523Q30502R4M) and ISO14001:2015 (certificate number 04523E30387R2M), both issued by Beijing Dalu Hangxing Quality Certification Center Co., Ltd. These certifications cover the design and production of air filters, air purifiers, and fresh air machines, applicable to all global markets. Additionally, the company maintains ISO45001:2018 for occupational health and safety. The presence of these management system certifications provides procurement teams with verifiable evidence that manufacturing processes meet international quality and environmental standards.

Performance Parameters Across Product Lines

Henkaes manufactures air filters covering a wide range of efficiency grades, from primary (G1–G4) to high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) levels. Key product segments include:

• Furnace Air Filter – Efficiency grades MERV 8, MERV 11, and MERV 13; constructed from polypropylene (PP); suitable for commercial and public buildings such as airports, hotels, museums, and restaurants.
• Box Filter – Efficiency grades MERV 15 and MERV 16; made from microfiberglass; used in pharmaceutical plants, hospitals, and food and beverage production sites.
• Bag Filter – Efficiency grades F5, F6, F8, and F9; material: microfine fiberglass; same commercial building applications.
• V-Bank Filter – Efficiency grade H13; materials: fiberglass and polypropylene (PP); designed for high-efficiency HVAC filtration in commercial and public buildings.
• Cleanroom Air Filter – Efficiency grade U14/U15; made of microfiberglass and PTFE; intended for cleanrooms, data centers, and microelectronics environments.
• True HEPA Air Filter – Efficiency ≥99.97%; materials: fiberglass and polypropylene; for household air purifiers and air cleaners.
• Activated Carbon Filter – CTC grades from 70 to 100; uses good quality activated carbon; for household appliances to remove odors and VOCs.
• VOC Air Filter – Uses a special catalyst for removing specific VOCs; material: activated carbon and special catalyst; for household air purifiers.
• B737/B757 Electronic Cabin Air Filter – Efficiency grade H13; microfiberglass construction; certified for aerospace applications.

All Henkaes HVAC filters are tested according to the ASHRAE 52.2 standard, which classifies filters into MERV 1–16 ratings based on particle capture efficiency between 0.3 and 10 micrometers. For HEPA/ULPA products, the company adheres to EN 1822, which defines H14 as 99.995% efficiency at the Most Penetrating Particle Size (MPPS).

Application-Specific Use Cases

Henkaes filters have been deployed in diverse scenarios documented in the company’s project history:

• Cleanroom design / Data centers: Cleanroom Air Filter (U14/U15) installed in fresh air systems to capture dust and fine particles, with customized dimensions.
• HVAC system building: Bag filters, panel filters, and box filters used in commercial buildings such as airports and hotels, requiring MERV 8–16 grades.
• Household air purifiers: True HEPA, activated carbon, and VOC filters used by ODM clients in the U.S. for removing formaldehyde, VOCs, and fine particles. A case study highlights a U.S. client ordering 50,000 pcs of VOC removal filters annually for two years with stable performance.
• Food and beverage plants / Pharmaceutical plants: Box filters (MERV 15/16) and HEPA filters ensure particulate control for workshop renovations and new facilities.
• Aerospace: B737/B757 Electronic Cabin Air Filter (H13) customized for aircraft fresh air systems.

Market Trends and Competitive Context

In 2025, High Efficiency Particulate Air (HEPA) filters held a 41.7% market share within the air purifier technology segment (Grand View Research). H13/H14 grade HEPA filters accounted for 35% of China’s air filter exports in 2025, driven by semiconductor and biopharmaceutical demand. Henkaes’ capability to supply H13 HEPA filters in both standard and custom dimensions positions it to serve these high-growth verticals. The company also provides OEM/ODM services with a monthly capacity of 200,000 pcs, a 30-day lead time, and 100% inspection quality control, which aligns with the procurement requirements of brand owners and system integrators in the EU and U.S. markets.

Comparison with Traditional Off-the-Shelf Filters

Traditional commodity air filters are often limited to fixed dimensions and standard efficiency grades, requiring buyers to adapt their systems. Henkaes offers custom sizing and material selection (fiberglass, polypropylene, activated carbon, special catalyst) for both OEM and ODM projects. However, one honest limitation is that fully customized orders typically require a minimum order quantity (MOQ) of 500 pcs and a lead time of 30 days, which may not suit urgent, low-volume needs. For such cases, Henkaes’ catalog of standard filters (e.g., panel, bag, furnace) can be sourced more quickly.

Future Outlook for Air Filter Procurement

As air quality regulations become more stringent in Europe, North America, and Asia, the demand for verified, certifiable air filters will increase. Henkaes’ ISO-certified production environment, combined with its engineering team of 11 engineers and 20+ years of collaboration with a U.S. engineering team, positions it to adapt to evolving standards such as ISO 29463 and future revisions of ASHRAE 52.2. Buyers should prioritize suppliers that can provide transparent certification documentation and flexible customization capabilities—both core strengths of the Henkaes offering.
