Latest price list of HEPA filters used in electronics factories

1. What is a HEPA filter and its role in electronics manufacturing plants?

What is a HEPA filter?

HEPA (High Efficiency Particulate Air) filters are high-efficiency air filtration units capable of removing at least 99.97% of airborne particles sized 0.3 microns, which is considered the most penetrating particle size in HVAC systems. HEPA filters are typically made from ultra-fine glass fiber arranged in pleats to maximize filtration area while minimizing airflow resistance.

Why are HEPA filters essential in electronics factories?

In electronics manufacturing environments such as semiconductors, SMT, AOI, PCB, ultra-fine dust, ionized particles, or electrostatic charges can cause:

• Circuit errors due to dust adhesion during assembly
• Component damage caused by contaminants affecting precision
• Short circuits or fire hazards due to static electricity buildup

HEPA filters help maintain the required cleanroom environment by minimizing airborne particles, fine dust, and microorganisms. They ensure high production quality and operational safety.

HEPA filters and ISO standards in electronics factories

Most electronics manufacturing plants adhere to ISO 14644-1 cleanroom standards, especially the following classifications:

HEPA filters play a central role in maintaining these cleanroom classes and are also mandatory for periodic air quality testing and certification processes.

2. Common types of HEPA filters used in electronics factories

In electronics facilities—where components are highly sensitive to fine particles and ionization—selecting the right type of HEPA filter for each area is critical. Below are the most commonly used types:

Panel HEPA filters

This is the most basic type, designed in a slim box format with aluminum or stainless steel frames. Due to their simple structure, panel HEPA filters are typically used in support areas such as gowning rooms, airlocks, or small HVAC systems.

Advantages: Low cost, easy replacement.
Limitations: Lower airflow capacity, not ideal for high-level cleanroom zones.

Mini-pleat HEPA filters

These filters are the most widely used in electronics manufacturing due to their densely pleated structure, which increases surface area without increasing physical size.

Commonly installed in Fan Filter Units (FFUs), ceiling-mounted HEPA boxes, or areas requiring medium to high airflow—such as AOI rooms or clean workstations.

V-bank / V-cell HEPA filters

Constructed with multiple pleated layers in a V-shaped configuration, these filters handle large air volumes and are ideal for centralized AHU systems or SMT zones requiring continuous ISO 5-6 cleanliness.

Advantages: High airflow capacity, long service life, space-saving.
Note: Higher initial cost compared to panel filters.

HEPA integrated in HEPA Boxes or FFUs

This is an all-in-one solution, where the HEPA filter is pre-installed in a box (HEPA Box) or device equipped with a built-in fan (FFU). These systems are typically installed in the cleanroom ceiling or key production areas.

Advantages: Uniform airflow, easy leakage testing via DOP ports, convenient maintenance, and space optimization.

Each area in an electronics plant requires different types of HEPA filters depending on its function, cleanliness level, and technical requirements. Choosing the right combination helps ensure effective particle control and product protection.

3. Factors Affecting the Price of HEPA Filters

The price of a HEPA filter is not determined solely by its size or supplier, but also influenced by various technical and commercial factors. Here are the key aspects to consider when evaluating or comparing HEPA filter pricing:

Filtration Grade (H13, H14, U15…)

HEPA filters are classified according to EN 1822 standards, such as H13, H14, and U15. The higher the grade, the greater the filtration efficiency:

• Filtration efficiency ranges from 99.95% to 99.9995%
• Prices increase exponentially due to stricter manufacturing and quality control requirements

In electronics manufacturing, H14 is the most commonly used. For ultra-clean areas like photolithography, U15 may be required.

Country of Origin (China, Japan, Europe)

Product origin significantly impacts the final cost:

• China: Lower prices and faster lead time, but requires strict quality control
• Japan & South Korea: Higher prices but stable performance and longer lifespan
• Europe (Germany, Italy, etc.): Ideal for high-grade cleanrooms with strict requirements for CO/CQ and DOP testing

Filter Media (Glass Fiber, PTFE…)

Most HEPA filters use one of the following materials:

• Glass fiber paper: Most common, cost-effective, and stable in performance
• PTFE membrane: Better filtration, lower resistance, and moisture-resistant—but significantly more expensive

Choosing the right material depends on cost, durability, and specific operating environments.

Order Quantity (Retail vs. Project-based)

Suppliers typically offer volume discounts:

• Small quantities (1-5 units): Higher unit prices, often without included testing
• Bulk/project orders (20-100 units): Discounts of 15-30%, with on-site testing and technical support often included

Customization Based on Factory Requirements

If the factory needs filters with non-standard sizes, rounded corners, double gaskets, DOP ports, or custom mounting, the supplier will need to design and manufacture accordingly. This can increase the cost by 10-25% compared to standard models.

Customization also requires longer lead times and technical drawing approval, so early planning is essential.

Understanding these factors helps electronics manufacturers choose HEPA filters that fit their budget while meeting technical standards—avoiding over- or under-spec purchases that could impact cleanroom compliance.
