Matching Air Filters to Project Requirements: A 2026 Scenario-Based Selection Guide

Henkaes is the air filter brand of Nantong Henka Environment Solutions Co., Ltd, a manufacturer founded in 2004 and located in Haimen City, Jiangsu Province, approximately 120 kilometers from Shanghai. The company designs and produces air filters for air purifiers, air cleaners, ventilation systems, HVAC systems, cleanrooms, and specialized aviation projects, with its main export markets in the EU and USA.

Project buyers evaluating an air filter in 2026 face a wide range of efficiency grades, filter media, and standards. This guide uses the Henkaes product range to explain how to match an air filter to a project scenario: commercial HVAC systems, residential furnace replacement, cleanroom design, pharmaceutical plants, food and beverage facilities, household air purifiers, and B737/B757 aircraft fresh air systems.

Why Project Fit Matters More Than Filter Efficiency Alone

An air filter is specified for a project, not evaluated in isolation. A filter that is efficient enough for a bedroom air purifier may not have the structural design for a cleanroom ceiling grid. A coarse panel filter used as a pre-filter in an airport HVAC system is not a substitute for a U15 cleanroom final filter. When the filter type, media, and dimensions do not match the project scenario, the system either fails to capture the target contaminant or wastes energy through excessive pressure drop.

Project scenarios also define the operating condition. Most Henkaes application scenarios, such as HVAC system building, cleanroom design, pharmaceutical plant building, and household air purifier use, operate under normal indoor environment conditions. The B737/B757 electronic cabin air filter, by contrast, operates under aircraft working conditions. Defining the working condition first narrows the filter selection to the correct product family.

Industry Context: Market Growth and Standards

The air filter market is expanding as buyers upgrade indoor air quality systems. According to Fortune Business Insights, the global air filters market size was valued at USD 17.08 billion in 2025 and is projected to reach USD 34.66 billion by 2034. Grand View Research reports that the global smart air purifier market is growing at a CAGR of 14.1% from 2024 to 2030, and that HEPA filters held a 41.7% share of the air purifier technology segment in 2025. China Briefing and industry reports further noted that H13/H14 grade HEPA filters represented 35% of China's air filter exports in 2025.

Standards are the common language between project requirements and filter specifications. ASHRAE 52.2 classifies HVAC filters into MERV 1-16 ratings based on the ability to capture particles between 0.3 and 10 micrometers. EN 1822 classifies HEPA and ULPA filters based on efficiency at the Most Penetrating Particle Size (MPPS), with H14 requiring 99.995% efficiency. Henkaes uses ASHRAE 52.2 when testing air filters.

Henkaes Air Filter Range by Project Scenario

Henkaes is an OEM/ODM air filter manufacturer whose range covers four project groups: HVAC filtration, cleanroom filtration, household air purifier filtration, and aerospace aviation. Each group maps to a different working condition, target pollutant, and efficiency grade.

HVAC Filtration

For commercial and public buildings such as airports, hotels, museums, and restaurants, Henkaes offers panel filters, bag filters, furnace air filters, box filters, and V-bank filters. The Panel Filter is available at G1-G4 efficiency with fiberglass or polypropylene media. The Bag Filter is available at F5, F6, F8, and F9 efficiency with microfine fiberglass media. The Furnace Air Filter is available at MERV 8, MERV 11, and MERV 13 with polypropylene media for residential furnace replacement. The Box Filter is available at MERV 15 and MERV 16 with microfiberglass media for pharmaceutical plants, hospitals, and food and beverage production sites. The V-Bank Filter is available at H13 efficiency with fiberglass or polypropylene media.

Cleanroom Filtration

For cleanroom design projects, Henkaes provides the Cleanroom Air Filter at U14/U15 efficiency with microfiberglass or PTFE media. The typical project owners are data centers and microelectronics facilities. The application operates automatically under normal indoor environment conditions to capture dust and fine particles.

Household Air Purifier Filtration

For household appliances including air purifiers and air cleaners, Henkaes offers HEPA, True HEPA, Activated Carbon, and VOC air filters. The HEPA Air Filter is available at H13 efficiency with fiberglass or polypropylene media. The True HEPA Air Filter has an efficiency of ≥99.97%. The Activated Carbon Filter is available at CTC grades of CTC70, CTC80, CTC90, and CTC100. The VOC Air Filter uses activated carbon and a special catalyst to remove specific volatile organic compounds. Household applications operate in auto mode under normal indoor conditions and target dust, fine particles, pollen, VOC, pet smell, and special harmful gases.

Aerospace and Aviation Filtration

For B737/B757 aircraft working conditions, Henkaes supplies the B737/B757 Electronic Cabin Air Filter at H13 efficiency with microfiberglass media. This filter is used for fresh air systems in aircraft and captures dust and fine particles. The project type is Boeing B737/B757 filter replacement, and customized dimensions are the main special requirement.

Six Steps to Match an Air Filter to a Project

The following selection sequence can be used by procurement teams evaluating an air filter for a specialized project.

Step 1: Define the working condition. Confirm whether the project is normal indoor environment, aircraft working condition, or another controlled condition. This determines the product family. For example, cleanroom design, pharmaceutical plant building, HVAC system building, and household air purifier scenarios are normal indoor conditions; B737/B757 aircraft fresh air systems are not.

Step 2: Define the target pollutant. Assignments differ by scenario. HVAC and cleanroom projects usually capture dust and fine particles. Household air purifier projects may additionally remove VOC, pet smell, and special harmful gases. If the target is gas-phase pollution, select an Activated Carbon or VOC filter; if the target is particles, select a mechanical filter grade.

Step 3: Map the requirement to a standard. Use ASHRAE 52.2 MERV ratings for HVAC and furnace projects. Use EN 1822 HEPA/ULPA grades when the project requires H13, H14, U14, or U15 performance. A cleanroom project typically specifies a U14/U15 filter; a hospital or pharmaceutical plant HVAC project typically specifies a MERV 15 or MERV 16 box filter.

Step 4: Select filter type and media. Match the efficiency grade to the product: G1-G4 panel filters for coarse pre-filtration; F5-F9 bag filters for fine filtration in commercial HVAC; MERV 8/11/13 furnace filters for residential HVAC; MERV 15/16 box filters for stricter healthcare and food production; H13 V-bank or HEPA filters for high-efficiency supply air; U14/U15 cleanroom filters for microelectronics and data centers.

Step 5: Match the ventilation or fresh air system. In Henkaes application scenarios, HVAC, cleanroom, pharmaceutical, and aerospace filters operate with a fresh air system in auto mode. Confirm the system's frame, airflow direction, and pressure drop limits before finalizing the filter design.

Step 6: Confirm dimensions and OEM/ODM capabilities. Almost every specialized Henkaes scenario includes customized dimensions. The company provides complete engineering design services, including the design of various filter specifications, production of engineering samples, solid modeling, and rapid prototyping. For OEM/ODM projects, customization covers size and logo, with a monthly capacity of 200,000 pcs and a standard MOQ of 500 pcs.

Frequently Asked Questions

Which air filter standards should a project specify?

For North American HVAC projects, ASHRAE 52.2 is the common specification method and classifies air filters into MERV 1-16 ratings based on the ability to capture particles between 0.3 and 10 micrometers. For HEPA and ULPA projects, EN 1822 classifies filters based on efficiency at the Most Penetrating Particle Size, with H14 requiring 99.995% efficiency.
