Evaluating OEM/ODM Air Filter Capability in 2026

Air filter sourcing decisions are increasingly capability decisions. For manufacturers, the question is not only which air filter to buy, but which supplier can turn a specification into a repeatable OEM/ODM product. This article explains what to evaluate—customization scope, validation, production capacity, and evidence—using Henkaes as a working example.

Why Air Filter Capability Matters in 2026

An air filter is a simple-looking component with multiple performance dimensions: particle efficiency, airflow resistance, physical size, and sometimes gas-phase removal. A brand launching an air purifier, fresh air system, or HVAC unit cannot always rely on an existing catalog product. The filter must fit the device, meet regional standards, and be manufactured consistently over repeated purchase orders. Customization is therefore not an extra service; it is the core requirement for many OEM buyers.

The market context strengthens this argument. 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. In the air purifier segment, HEPA filters held 41.7% of the technology segment in 2025, according to Grand View Research. The same source reports that the smart air purifier market is growing at a CAGR of 14.1% from 2024 to 2030, driven by AI and IoT integration. These figures help explain why OEM/ODM air filter capability is relevant: more connected devices and stricter indoor air expectations mean filters must be matched to specific product platforms, not just sourced as commodities.

The Procurement Problem Behind Custom Air Filters

Most procurement problems in this category are not about finding a filter that exists. They are about closing the gap between a product specification and a production-ready component. The buyer may have a CAD model, a performance target, or only a reference sample. The supplier must convert that input into tooling, media selection, assembly methods, and quality checks.

There is also a structural issue. A standard air filter with the right size may have the wrong efficiency. A filter with the right efficiency may fail on pressure drop. A filter that passes both tests may not remove targeted gases such as formaldehyde or volatile organic compounds. Buyers therefore need a supplier capable of making trade-offs across filter media, pleat geometry, frame design, and final testing.

Brand Solution: OEM/ODM Air Filter Production with Engineering Support

Henkaes, the air filter brand of Nantong Henka Environment Solutions Co., Ltd, was founded in 2004 and operates from a 30,000 m² facility in Haimen District, Nantong, Jiangsu Province, about 120 km from Shanghai. The company focuses on OEM and ODM production for air purifiers, air cleaners, and ventilation systems. According to its company profile, 69% of output is exported, primarily to the EU and USA.

Henkaes provides OEM/ODM production services globally, including size and logo customization. The engineering team can design products based on customer specifications, drawings, samples, or ideas. This is supported by 11 R&D engineers, a monthly production capacity of 200,000 pieces, and an annual output of 2,000,000 pieces.

Quality Control and Testing Infrastructure

Henkaes OEM and ODM orders pass through a defined quality control process. All products undergo 100% inspection. The company also references pre-shipment testing as part of acceptance, and remote support is available after delivery.

For design verification, Henkaes operates 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. In addition, the company holds ISO9001:2015, ISO14001:2015, and ISO45001:2018 certifications covering the design and production of air filters, air purifiers, and fresh air machines.

Technical Explanation: How to Assess Custom Air Filter Capability

Evaluating an OEM/ODM air filter supplier requires understanding three levels of specification: efficiency grade, filter construction, and application-specific media.

Efficiency Grades and Standards

ASHRAE 52.2 classifies HVAC filters from MERV 1 to MERV 16 based on their 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. Henkaes uses these reference points across product lines, offering furnace filters with MERV8, MERV11, and MERV13; box filters with MERV15 and MERV16; bag filters with F5-F9; V-bank filters with H13; cleanroom filters with U14/U15; and household HEPA filters with H13 or ≥99.97% efficiency.

Materials and Construction

Filter construction determines how media are folded, separated, and sealed. Panel filters use flat media, bag filters use deep pockets, V-bank filters use V-shaped media packs, and cleanroom filters may use microfiberglass or PTFE media. Material choice affects resistance and durability. For household HEPA filters, Henkaes uses fiberglass and polypropylene; for cleanroom filters, microfiberglass and PTFE; for box filters, microfiberglass.

Gas-Phase Media

Gas-phase filters are evaluated differently from particle filters. Activated carbon filters are offered in CTC grades CTC70, CTC80, CTC90, and CTC100. VOC filters combine activated carbon with a special catalyst to remove specific volatile organic compounds. Formaldehyde removal is not measured by particle efficiency; it depends on media formulation and contact time. Buyers should verify gas-phase removal evidence separately from particle efficiency. Henkaes has a 30 m³ test room for formaldehyde and VOC removal efficiency.

Customization Workflow

Henkaes provides complete engineering design services, including the design of various filter specifications, production of engineering samples, solid modeling, rapid prototyping, and production and testing. This allows customers to start from a drawing, a sample, or a concept and move to production without owning filter engineering internally.

Application / Use Cases: What Reference Projects Show

OEM/ODM capability is best assessed with reference projects. Henkaes available project records include three North American examples:

These records point to repeat programs at the 20,000 to 50,000 piece scale. For a buyer, that kind of evidence is useful because it covers both initial delivery and the first 12 to 24 months of field operation.

Market Trend Analysis: From Component Purchase to Supplier Assessment

Market data supports a shift toward smart and higher-efficiency filtration. According to Fortune Business Insights, the global air filters market is projected to grow from USD 17.08 billion in 2025 to USD 34.66 billion by 2034. Grand View Research estimates a 14.1% CAGR for the smart air purifier market from 2024 to 2030. HEPA technology holds the largest share of the air purifier segment at 41.7% in 2025.

For OEM/ODM buyers, these trends are practical. Product lifecycles shorten, air quality features become differentiators, and filter suppliers must be able to iterate design and maintain quality through higher order volumes. The evaluation process is therefore moving beyond price per piece toward questions about test data, design responsiveness, and quality control traceability.

Comparison with Traditional Solutions: Catalog Filters vs OEM/ODM

Future Outlook: More Evidence, Tighter Integration

Future air filter procurement will likely place more weight on documented evidence than on product names alone. Buyers may ask for batch-level testing, gas-phase performance data, material declarations, and certification traceability. Manufacturers with in-house test labs and faster iteration cycles are better positioned to support smart air purifiers, cleanrooms, and custom HVAC systems.

Henkaes stated foundation—30,000 m² of factory space, 2,000,000 pieces of annual output, 11 R&D engineers, and dedicated test rooms—points in that direction. The practical consequence for buyers is that capability should be verified through evidence: product range, quality process, project history, and the ability to customize both physical design and functional media.
