Henkaes OEM/ODM Air Filter Manufacturing: Proven Capability for Custom Solutions

Nantong Henka Environment Solutions Co., Ltd (Henkaes) is a Chinese manufacturer of air filters established in 2004, specializing in OEM (Original Equipment Manufacturing) and ODM (Original Design Manufacturing) for household, HVAC, cleanroom, and aerospace applications. This technical guide examines Henkaes’ end-to-end production capabilities, quality control processes, and documented project experience to help procurement teams assess whether the supplier can meet custom filtration requirements.

Why OEM/ODM Capability Matters in Air Filter Sourcing

Buyers in industrial and commercial filtration often require filters that deviate from standard catalogs—custom dimensions, specific efficiency grades, unique media, or branded packaging. The global air filter market, valued at USD 17.08 billion in 2025 and projected to reach USD 34.66 billion by 2034 (Fortune Business Insights), is increasingly driven by specialized applications. HEPA filters alone held 41.7% of the air purifier technology segment (Grand View Research). Identifying an OEM/ODM partner with proven manufacturing scale, testing infrastructure, and direct client experience reduces project risk during the evaluation-to-execution phase.

Henkaes’ Production and Customization Capabilities

Henkaes operates a 30,000 m² factory with 63 employees and 11 engineers. Annual output reaches 2,000,000 pieces. The manufacturer offers OEM and ODM production services globally, with customization options for size and logo. All products undergo 100% inspection as part of quality control. Monthly capacity is 200,000 pieces, lead time is 30 days, and minimum order quantity is 500 pieces. Payment terms are TT 50%/50%, with delivery methods including FOB, EXW, and DDP. Remote support is available for after-sales technical issues.

The company holds ISO9001:2015 (cert. 04523Q30502R4M), ISO14001:2015 (cert. 04523E30387R2M), and ISO45001:2018 certifications for design and production of air filters, air purifiers, and fresh air machines. Testing facilities include an efficiency and air resistance test system for filter media, noise test lab, 30 m³ test room for formaldehyde and VOC removal efficiency, CADR test room for air purifiers, and compliance to ASHRAE 52.2 for HVAC filter testing.

How the OEM/ODM Process Works
