HEPA Filters

Clean-Link supplies HEPA filter solutions for commercial, industrial, and controlled environments, supporting applications that require reliable removal of fine particulates and biological contaminants.

What Are HEPA Filters?

HEPA filters are high-efficiency air filters typically rated to capture at least 99.97% of particles at 0.3 microns, depending on the applicable standard and classification. They are constructed using fine glass fiber or synthetic filter media arranged to maximize surface area while maintaining controlled airflow resistance.

HEPA filtration is commonly specified in cleanrooms, healthcare facilities, laboratories, and critical process environments.

Contaminants Removed by HEPA Filtration

HEPA filters are designed to capture:

• Fine dust and airborne particulates

• Bacteria and microorganisms

• Allergens and biological contaminants

• Combustion particles and aerosols

• Process-generated fine particles

Due to their high efficiency, HEPA filters are often used as the final stage in a multi-stage air filtration system.

Typical Applications

HEPA filters are commonly applied in:

• Cleanrooms and controlled environments

• Hospitals and healthcare facilities

• Pharmaceutical and biotechnology production

• Laboratories and research facilities

• Data centers and critical technical rooms

• Electronics and precision manufacturing

Each application may have specific airflow, sealing, and compliance requirements that influence filter selection.

Standards and Efficiency Classes

Clean-Link HEPA filters are designed in accordance with commonly referenced international standards, including:

• EN 1822 (E10–H14 classifications)

• ISO 29463 (where applicable)

Filter selection should consider the required efficiency class, leakage performance, and test certification relevant to the application.

Filter Configurations and Options

HEPA filters are available in multiple configurations to accommodate different system designs, including:

• Mini-pleat HEPA filters

• Gel seal or gasket seal designs

• Aluminum, galvanized steel, or stainless steel frames

• Standard and custom dimensions

• High-temperature or specialized variants (where applicable)

Configuration selection depends on installation method, airflow conditions, and maintenance access.

Integration in Multi-Stage Filtration Systems

To ensure stable performance and extended service life, HEPA filters are typically installed downstream of:

• Prefilters for coarse particle removal

• Fine or medium-efficiency filters

Upstream filtration reduces dust loading on the HEPA filter, helping maintain airflow stability and predictable pressure drop over time.

Selection Considerations

Key factors when selecting HEPA filters include:

• Required efficiency and standard compliance

• Airflow rate and pressure drop limits

• Sealing method and housing compatibility

• Environmental conditions such as temperature and humidity

• Maintenance and replacement strategy

Proper selection ensures both filtration performance and operational reliability.

Manufacturing and Quality Control

Clean-Link manufactures HEPA filters under controlled production processes with consistent media pleating, frame integrity, and sealing performance. Products are designed for compatibility with common air handling units and filtration housings used in critical environments.
