Activated Carbon Pocket Filter

Clean-Link supplies activated carbon pocket filters for commercial and industrial applications where both molecular contamination control and operational efficiency are required.

What Is an Activated Carbon Pocket Filter?

An activated carbon pocket filter is a bag-style air filter that incorporates activated carbon media within flexible filter pockets. The pocket design increases media surface area and contact time, allowing efficient adsorption of gaseous pollutants while handling higher airflow volumes compared to flat carbon panels.

These filters are commonly used as a secondary or final filtration stage in HVAC systems requiring gas-phase air purification.

Key Contaminants Removed

Activated carbon pocket filters are designed to remove:

• Odors from organic and industrial sources

• Volatile organic compounds (VOCs)

• Chemical fumes and solvent vapors

• Low-concentration gaseous pollutants

• Mixed particulate and gas-phase contaminants (depending on media type)

The adsorption performance depends on carbon type, pocket depth, and airflow conditions.

Typical Applications

Activated carbon pocket filters are widely used in:

• Commercial buildings and office ventilation systems

• Hotels and hospitality facilities

• Airports and public infrastructure

• Healthcare facilities and laboratories

• Data centers and technical rooms

• Industrial HVAC systems requiring odor control

They are suitable for applications where extended filter life and consistent gas adsorption are important.

Advantages of Pocket-Style Carbon Filters

Compared to flat or panel carbon filters, pocket-style designs offer:

• Increased media surface area

• Lower pressure drop at higher airflow rates

• Extended service life due to higher adsorption capacity

• Improved airflow distribution within filter housings

These characteristics make activated carbon pocket filters suitable for continuous operation in large air handling units.

Filter Media and Configuration Options

Clean-Link activated carbon pocket filters are available with various media and design options, including:

• Carbon-loaded synthetic or nonwoven media

• Standard or impregnated activated carbon

• Multiple pocket depths and pocket counts

• Rigid frames for secure installation

• Standard and custom dimensions

Filter configurations can be tailored to specific system requirements and contaminant profiles.

Integration in Multi-Stage Filtration Systems

Activated carbon pocket filters are typically installed downstream of:

• Prefilters for coarse particle removal

• Fine or medium-efficiency filters

Upstream particulate filtration helps protect the carbon media, maintain adsorption efficiency, and extend service life.

Selection Considerations

When selecting activated carbon pocket filters, key factors include:

• Target gases and odor sources

• Airflow rate and available installation depth

• Required adsorption capacity

• Acceptable pressure drop limits

• Maintenance and replacement intervals

Proper selection ensures reliable gas-phase filtration performance over the intended operating period.

Manufacturing and Quality Control

Clean-Link manufactures activated carbon pocket filters with consistent media distribution, stable pocket construction, and dimensional accuracy.

Products are designed for compatibility with common HVAC filter housings used in commercial and industrial environments.
