Henkaes Long-Term Air Filter Partnership: OEM/ODM Supply

Henkaes is an air filter OEM/ODM manufacturer founded in 2004 and based in Haimen District, Nantong, Jiangsu Province, China, about 120 kilometers from Shanghai. The company designs and produces custom air filters for air purifiers, air cleaners, and ventilation systems. As the global air filters market moves from USD 17.08 billion in 2025 toward a projected USD 34.66 billion by 2034 (Fortune Business Insights), distributors, brand owners, and procurement teams are shifting from transactional orders to multi-year OEM/ODM supply relationships. This guide explains what Henkaes offers to buyers at the decision-to-execution stage: production capacity, engineering support, quality infrastructure, and commercial terms that make a long-term air filter partnership workable.

Why long-term air filter supply relationships fail

The recurring failure in air filter sourcing is not the quality of the first order; it is consistency in the orders that follow. When a distributor or appliance brand scales a product line, the manufacturer must hold tolerances across repeated batches, absorb seasonal demand spikes, and respond to specification changes without renegotiating the relationship each time. Capacity shortfalls, quality drift between batches, and slow engineering response are among the most frequent reasons buyers switch suppliers. Each of these risks is manageable when the manufacturer documents its capacity, testing infrastructure, and design process in advance. The sections below map those documented capabilities for Henkaes and show how a longer-term OEM/ODM arrangement is actually structured.

Air filter market context for long-term sourcing

Three verified market signals support early consolidation of air filter supply chains. First, 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 (Fortune Business Insights). This near-doubling of the market size over nine years means that capacity commitments made today will likely need to expand significantly. Second, HEPA filters held a 41.7% share of the air purifier technology segment in 2025 (Grand View Research), and the smart air purifier market is growing at a 14.1% CAGR from 2024 to 2030. Third, the industrial filtration market already shows consolidation at the top: Parker Hannifin led the global industrial filtration systems market with a 15.7% share in 2024 (Global Market Insights). For mid-sized distributors and brands, the practical implication is that supplier capacity — not just filter price — will be the limiting factor in serving the growing demand for HEPA, HVAC, and cleanroom filtration.

Standards also shape the long-term relationship. In North America, ASHRAE 52.2 classifies HVAC filters into MERV 1–16 ratings based on the ability to capture particles between 0.3 and 10 micrometers. In Europe, EN 1822 classifies HEPA and ULPA filters by efficiency at the Most Penetrating Particle Size, with H14 requiring 99.995% efficiency. Buyers who plan to sell into both regions need a manufacturer that can test against the relevant standard and design filters that meet the regional classification.

Henkaes OEM/ODM long-term supply model

Henkaes is a customized air filter supplier for air purifier and air cleaner brands in the North American market and the China market. The long-term supply model is built on four documented capabilities: production scale, engineering depth, quality infrastructure, and stable commercial terms.

Production capacity

Henkaes operates a 30,000 m² factory with 63 employees and reports a monthly production capacity of 200,000 pieces, or roughly 2,000,000 pieces per year. This level of output supports continuous replenishment for distributors and scheduled production windows for OEM customers. A monthly capacity of 200,000 pieces across multiple filter lines is sufficient to serve national appliance brands while keeping the factory responsive to custom specifications — the volume needed for long-term programs without the rigidity of single-purpose production lines.

Engineering and customization depth

Henkaes employs an R&D team of 11 engineers and has more than 20 years of experience working with a US engineering team. Customers can submit specifications, drawings, samples, or even initial ideas, and Henkaes provides complete engineering design services: design of various filter specifications, production of engineering samples, production and testing, solid modeling, and rapid prototyping. For OEM/ODM buyers, this means the product is engineered before the purchase order is placed, reducing the risk of specification mismatch during serial production.

Quality infrastructure and certifications

Henkaes holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications. The factory is equipped with an efficiency and air resistance test system for filter media, a noise test lab, a 30 cubic meter test room for formaldehyde and VOC removal efficiency, and a CADR test room for air purifiers. ASHRAE 52.2 is used in testing air filters, the standard that classifies HVAC filter performance across MERV 1–16. The company's HEPA line is rated H13; the True HEPA line is rated ≥99.97% efficiency; and the cleanroom line is rated U14/U15 with microfiberglass or PTFE media. For replacement-life management, Henkaes reminds customers to replace the product when the service lifespan is closing, which reduces the risk of running filters past their useful life.

Commercial terms for repeat orders

Henkaes's standard commercial terms are designed for repeatable execution: a minimum order quantity of 500 pieces, a typical lead time of 30 days, delivery under FOB, EXW, or DDP, acceptance through pre-shipment testing, and payment via 50% deposit / 50% balance by T/T. Pre-shipment testing matters for long-term buyers because it places the final quality check before goods leave the factory rather than after they arrive at the destination port.

Product portfolio across efficiency classes

Henkaes publishes its product specifications across household, HVAC, cleanroom, and aerospace applications. The table below summarizes the documented efficiency grades, materials, and typical end-uses.

Step-by-step: how a Henkaes OEM/ODM engagement works

A long-term partnership with Henkaes typically follows a six-step path, with each stage documented in the company's standard practice:

1. Submit the requirement. The customer provides a specification, drawing, sample, or an idea. The engineering team evaluates the filter type, efficiency grade, media, and target application.
2. Engineering design. Henkaes provides design services including solid modeling and rapid prototyping, so the customer can evaluate form, fit, and performance before tooling or mass production.
3. Engineering samples. Samples are produced and tested using the factory's efficiency and air resistance test system, noise test lab, 30 m³ formaldehyde/VOC test room, and CADR test room.
4. Order confirmation. The order is placed under a 500-piece minimum, with 50%/50% T/T payment and a choice of FOB, EXW, or DDP delivery.
5. Serial production. At a monthly capacity of 200,000 pieces, the factory runs the order with a typical lead time of 30 days.
6. Pre-shipment testing and delivery. Goods are tested before shipment, then dispatched under the agreed delivery term.

Use cases for Henkaes long-term supply

Household air purifier brands. For OEM/ODM customers serving the North American and Chinese air purifier markets, Henkaes supplies HEPA, True HEPA, activated carbon (CTC 70–100), VOC removal, and formaldehyde removal filters. HEPA technology's 41.7% share of the air purifier technology segment in 2025 (Grand View Research) makes this line a central part of household air purifier programs.

HVAC and commercial building maintenance. Distributors that supply airports, hotels, museums, and restaurants can consolidate pre-filters and fine filters from one manufacturer: panel (G1–G4), bag (F5–F9), V-bank (H13), box (MERV 15/16), and furnace filters (MERV 8/11/13). Consolidation reduces SKU fragmentation and simplifies long-term stock planning.

Cleanroom and life-sciences projects. Henkaes produces cleanroom air filters at U14/U15 with microfiberglass or PTFE media for data centers and microelectronics, and box filters with MERV 15/16 for pharmaceutical plants, hospitals, and food-and-beverage production sites.

Aerospace and aviation maintenance. The B737/B757 electronic cabin air filter (H13, microfiberglass) is a documented product line for the aviation segment.

Distributor and wholesale channels. Because Henkaes produces under the customer's brand as an ODM manufacturer, distributors can build a private-label air filter portfolio across HEPA, activated carbon, and HVAC lines without operating their own production facility.

Product comparison: Henkaes versus common-equivalent filters

Henkaes's engineering data positions its filters against common equivalents in seven categories. The table below summarizes the documented comparison points. Across the product lines, Henkaes reports either a lower air pressure drop at the same efficiency or a higher carbon quality grade (CTC above 70), with no price increase and a longer replacement lifespan.

Note: differences are as documented in Henkaes's product comparison data against the listed common-equivalent filters. Results can vary with application conditions. The comparison data also reports higher Energy Star alignment across these product lines.

FAQ: long-term air filter OEM/ODM partnerships

Conclusion

For buyers at the decision-to-execution stage, a long-term air filter partnership depends on four verifiable variables: production capacity, engineering responsiveness, quality infrastructure, and commercial terms. Henkaes, as a manufacturer founded in 2004 with a 30,000 m² facility and monthly capacity of 200,000 pieces, documents all four. The product portfolio spans household, HVAC, cleanroom, and aerospace applications, and the standard terms — 500-piece MOQ, 30-day typical lead time, pre-shipment testing, and FOB/EXW/DDP delivery — are structured for repeatable execution rather than one-off transactions.
