High-efficiency V-bank filters are commonly used in commercial HVAC systems to capture fine particles.

Air filtration requirements vary significantly across industries. While standard off-the-shelf filters serve general HVAC needs, demanding environments—such as cleanrooms, pharmaceutical plants, food processing facilities, and aircraft cabins—require precisely engineered solutions tailored to unique dimensions, efficiency levels, and contaminant types. For procurement professionals evaluating OEM partners in 2026, the ability to match air filter specifications to specific project scenarios has become a critical selection criterion.

Problem / Opportunity

Standard filters often fail under niche working conditions. Dimensional mismatches, insufficient particle capture, or inadequate chemical adsorption can compromise air quality, regulatory compliance, and equipment longevity. Conversely, a custom-engineered filter that fits the exact application can improve system efficiency, reduce energy costs, and extend maintenance intervals. The growing demand for specialized filtration—driven by semiconductor manufacturing, biopharmaceuticals, and IAQ (indoor air quality) regulations—presents an opportunity for manufacturers to offer project-specific solutions.

Brand Solution: Henkaes’ Project-Adapted Air Filters

Henkaes (Nantong Henka Environment Solutions Co., Ltd), established in 2004 and operating a 30,000 m² factory with 63 employees, positions itself as a supplier of customized air filters for air purifiers, air cleaners, and ventilation systems. The company offers a broad portfolio that includes True HEPA Air Filters (efficiency ≥99.97%), HEPA Air Filters (H13), VOC Removal Filters (special catalyst), Activated Carbon Filters (CTC70–CTC100), Cleanroom Air Filters (U14/U15), and HVAC filters such as Panel (G1–G4), Bag (F5–F9), V-Bank (H13), Box (MERV15–MERV16), and Furnace Air Filters (MERV8–MERV13). Notably, Henkaes also produces a B737/B757 Electronic Cabin Air Filter (H13) for the aerospace industry.

With an annual output of 2,000,000 pcs and a monthly capacity of 200,000 pcs in OEM/ODM mode, Henkaes offers customization in both size and logo. Lead time is 30 days and the minimum order quantity is 500 pcs. The R&D team of 11 engineers, supported by a US engineering team, can design products based on specifications, drawings, samples, or customer ideas. All products undergo 100% inspection, and the factory is ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified.

Custom-sized furnace air filters are designed to fit varying residential HVAC configurations.

Technical Explanation: Matching Filters to Working Conditions

Henkaes classifies its filters by efficiency grade, material, and applicable industry. For example:

• Panel Filters (G1–G4) in fiberglass or polypropylene are used as pre-filters in commercial buildings (airports, hotels, museums).
• Bag Filters (F5–F9) in microfine fiberglass offer fine particle capture for the same commercial settings.
• Box Filters (MERV15–MERV16) in microfiberglass target pharmaceutical plants, hospitals, and food & beverage production sites.
• Cleanroom Air Filters (U14/U15) in microfiberglass or PTFE achieve ultra-low penetration for data centers and microelectronics.
• VOC Air Filters use good-quality activated carbon and a special catalyst to remove targeted volatile organic compounds.

According to the company’s application scenario data, projects in the United States and the Netherlands frequently require customized dimensions. The filters operate in automatic mode, are matched with fresh air systems, and are designed for normal indoor environment conditions. For specialized uses like the B737/B757 air filter, the working condition is specific to aircraft operations in China, removing dust, fine particles, and VOCs.

Application / Use-Case Scenarios

The following project types illustrate how Henkaes’ filters are applied:

• Household Air Purifiers (US, NL): Filters capture dust, fine particles, and pollen; remove VOC, pet smell, and special harmful gases. Special requirement: customized dimensions.
• Cleanroom Design (US, NL): Auto-mode operation to capture dust and fine particles under normal indoor conditions; customized dimensions required.
• Pharmaceutical Plants (US, NL): Auto-mode operation capturing dust and fine particles; customized dimensions are a standard requirement.
• Food & Beverage Plants (CN): Workshop renovation with fresh air system; customized dimensions.
• Aerospace (CN): B737/B757 aircraft cabin filter replacement; captures dust and fine particles; operates under aircraft working conditions.

In each case, Henkaes tailors the filter size, media type, and efficiency grade to the exact environmental and regulatory needs, ensuring compliance with standards like ASHRAE 52.2 and EN 1822.

Bag filters are a common choice for medium- to high-efficiency filtration in commercial HVAC systems.

Market Trend Analysis

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). High Efficiency Particulate Air (HEPA) filters held a 41.7% market share in the air purifier technology segment in 2025 (Grand View Research). The smart air purifier market is growing at a CAGR of 14.1% from 2024 to 2030, driven by AI and IoT integration (Grand View Research). Additionally, H13/H14 grade HEPA filters represented 35% of China’s air filter exports in 2025, fueled by the semiconductor and biopharmaceutical sectors (China Briefing). These trends underscore the rising demand for high-efficiency, application-specific air filters across both residential and industrial segments.

Comparison with Traditional Solutions

Traditional air filter suppliers often offer limited customization, restricting buyers to standard sizes and efficiency grades. Henkaes’ OEM/ODM capability allows for dimension and logo customization, supporting niche dimensions and unique contaminant removal requirements. However, one honest limitation is the minimum order quantity of 500 pcs per size, which may be challenging for small-scale pilot projects or very low-volume applications. For larger production runs—common in commercial and industrial projects—this MOQ is typically manageable and enables cost-effective manufacturing.

Future Outlook

As regulations tighten on indoor air quality and as advanced manufacturing facilities require class 1–10 cleanrooms, the ability to source custom air filters with verified performance will become a competitive advantage. Manufacturers like Henkaes, with ISO management systems, in-house testing (ASHRAE 52.2, CADR test room, 30 m³ VOC test chamber), and a proven track record of stable supply to US brands for over two years (as shown in two case studies of 50,000 pcs shipments), are well-positioned to serve buyers moving from generic procurement to project-specific specification.
