Our HEPA filter manufacturing support is built around project requirements, not only catalog models. Buyers can specify size, filter construction, frame material, gasket type, airflow, pressure drop target, efficiency class, installation method, documentation needs, and packaging requirements.

H13 and H14 HEPA Filter Manufacturing Capabilities

Clean-Link supports H13 and H14 HEPA filter projects for B2B applications where high-efficiency final filtration is required.

Typical H13 and H14 HEPA filter requirements may include:

• High-efficiency particle filtration
• Cleanroom HVAC final filtration
• Terminal HEPA filter modules
• Equipment-level HEPA filtration
• Industrial high-efficiency filtration
• Pharmaceutical and biotechnology environments
• Electronics and controlled production areas
• Replacement filters for existing HEPA housings
• OEM HEPA filter production

For each project, HEPA filter selection should consider more than efficiency class. Airflow, pressure drop, filter face area, sealing structure, frame strength, installation space, prefiltration, and test requirements all affect whether a filter is suitable for the system.

Clean-Link can review your project details and recommend a suitable HEPA filter structure based on confirmed specifications.

Mini-Pleat and Deep-Pleat HEPA Filter Options

Different HEPA filter designs are used for different airflow, space, pressure drop, and installation requirements.

Mini-Pleat HEPA Filters

Mini-pleat HEPA filters use closely spaced pleated media to provide a large filtration area within a compact structure.

They are commonly used in:

• Cleanroom ceiling systems
• HVAC final filter stages
• Compact air handling units
• Laboratories
• Electronics manufacturing environments
• Pharmaceutical production areas
• Terminal HEPA filter installations

Mini-pleat HEPA filters are often selected when the project requires compact depth, stable airflow, and high media area within limited installation space.

Deep-Pleat HEPA Filters

Deep-pleat HEPA filters are used where a deeper filter structure is suitable for the system.

They may be selected for:

• Industrial air handling systems
• High-airflow HEPA filter banks
• Replacement HEPA filter systems
• Equipment filtration
• Applications requiring stronger frame support
• Certain cleanroom or process ventilation systems

Deep-pleat construction should be matched with the airflow, pressure drop target, frame design, installation depth, and sealing requirements of the project.

Custom HEPA Filter Manufacturer for Project Requirements

Many HEPA filter projects require custom manufacturing because standard sizes or standard configurations do not match the system.

Clean-Link supports custom HEPA filters for:

• Non-standard dimensions
• Special filter depth
• Existing HEPA housing replacement
• Retrofit filter banks
• Cleanroom ceiling modules
• OEM equipment integration
• Industrial ventilation systems
• Special frame or gasket requirements
• Private-label or bulk supply programs

Custom HEPA filter specifications may include:

Custom Option	Available Project Considerations
Dimensions	Length, width, depth, actual size, non-standard size
Filter construction	Mini-pleat, deep-pleat, separator, box type, flange type
Efficiency	H13, H14, or project-specified efficiency requirement
Frame material	Aluminum, galvanized steel, stainless steel, or project-specific frame
Seal type	Gasket, gel seal, or project-specific sealing design
Media	HEPA media selected according to efficiency and airflow requirements
Airflow	Rated airflow or project airflow requirement
Pressure drop	Initial resistance and final resistance review
Installation	Ceiling terminal, AHU bank, equipment housing, duct module
Documentation	Datasheet, drawing, inspection data, test data where applicable
Packaging	Export packing, bulk packing, OEM or private-label packaging

 

Customization should solve a real system requirement, not only change the dimensions of a standard filter.

Frame Options: Aluminum, Galvanized Steel and Stainless Steel

HEPA filter frame selection affects strength, sealing, installation compatibility, corrosion resistance, and replacement handling.

Clean-Link can support different HEPA filter frame options depending on the project:

Aluminum Frames

Aluminum frames are commonly used for many cleanroom, commercial HVAC, and equipment-level HEPA filter applications. They are lightweight, stable, and suitable for many standard and custom HEPA filter designs.

Galvanized Steel Frames

Galvanized steel frames may be selected where stronger mechanical structure or specific industrial housing compatibility is required.

Stainless Steel Frames

Stainless steel frames may be considered for applications where corrosion resistance, cleaning requirements, or specific project environments make stainless construction more suitable.

Frame selection should be reviewed together with gasket type, installation method, airflow, filter weight, handling conditions, and system environment.

Gasket and Gel Seal Options

Proper sealing is critical for HEPA filter performance in real systems.

Even when a HEPA filter has the required efficiency rating, poor sealing, wrong gasket placement, frame mismatch, or housing leakage may allow air bypass.

Clean-Link can support:

• Upstream or downstream gasket configurations
• Foam gasket options
• EPDM or other gasket materials where applicable
• Gel seal options for suitable cleanroom systems
• Flange or box-type sealing designs
• Custom gasket position according to housing requirements

For cleanroom, pharmaceutical, electronics, and controlled process applications, gasket and sealing requirements should be confirmed before production.

Useful buyer information includes housing photos, installation drawings, gasket location, existing filter sample, airflow direction, and replacement method.

Airflow and Pressure Drop Review

HEPA filters should be selected according to both efficiency and system airflow capability.

A higher-efficiency filter is not automatically suitable for every system. The filter must work with the required air volume, fan capacity, installation area, prefiltration stage, pressure drop target, and replacement plan.

Important airflow and pressure drop factors include:

• Rated airflow
• Face velocity
• Initial pressure drop
• Recommended final pressure drop
• Filter face area
• Media area
• Installation depth
• Fan capability
• Existing system resistance
• Upstream prefiltration
• Operating hours and dust load

If airflow is too high for the filter area, resistance may increase and service life may be shortened. If the pressure drop is too high for the system, airflow may decline and equipment performance may be affected.

Clean-Link can help review HEPA filter specifications based on airflow, pressure drop, installation space, and application environment.

HEPA Testing and Leakage Testing Support

HEPA filter buyers often require documentation related to efficiency, resistance, integrity, or leakage testing.

Clean-Link can support HEPA testing and inspection requirements according to product type and confirmed project specifications.

Testing and inspection support may include:

• Visual inspection
• Dimension inspection
• Frame and gasket inspection
• Airflow resistance data where applicable
• Efficiency-related test data where applicable
• Leakage testing support where applicable
• Scan test support where applicable
• Individual test report discussion for project-based HEPA filters
• Datasheet and drawing support
• Packaging inspection for OEM or export orders

Testing scope, test method, report format, and acceptance requirements should be confirmed before production.

For HEPA and ULPA classification and testing context, buyers may refer to EN 1822 and ISO 29463 standards. Clean-Link can support project discussion based on the standard, efficiency class, testing expectation, and application requirement specified by the buyer.
