Air Filter Media – Synthetic, Fiberglass, HEPA, Carbon and Industrial Filter Media

Air Filter Media is the functional material inside an air filter that captures airborne particles or, in gas-phase applications, adsorbs selected odors, VOCs and gaseous contaminants.

The media is one of the most important components determining filtration efficiency, pressure drop, dust-holding capacity, service life and suitability for a particular application.

VIETPHAT supplies a wide range of Air Filter Media including synthetic fiber media, polyester media, fiberglass media, glass-fiber fine filter media, HEPA media, activated carbon media, paint booth ceiling media, fiberglass paint arrestor media, filter rolls and custom-cut filter pads for HVAC, AHU, FCU, cleanroom, industrial and spray booth applications.

What Is Air Filter Media?

Air Filter Media is the material through which air passes during filtration.

Depending on its structure and composition, the media may be designed to:

• Capture coarse dust.
• Capture fine particulate matter.
• Reduce PM10.
• Reduce PM2.5.
• Reduce PM1.
• Provide HEPA-level particulate filtration.
• Capture paint overspray.
• Adsorb selected odors and VOCs.
• Protect downstream filters and HVAC equipment.

Filter media may be supplied as raw rolls, cut pads, pleated packs, bags, pockets, mini-pleat packs, cartridges or fully assembled filters.

Why Is Air Filter Media Important?

Two filters with the same dimensions can perform very differently if their media is different.

Air filter media influences:

• Filtration efficiency.
• Initial pressure drop.
• Average operating pressure drop.
• Dust-holding capacity.
• Paint-holding capacity.
• Mechanical strength.
• Moisture resistance.
• Temperature resistance.
• Gas adsorption capability.
• Filter service life.

Air Filter Media for Pre Filters

Pre-filter media is designed primarily to remove larger airborne particles and protect downstream filters.

Common media include:

• Polyester fiber.
• Polypropylene fiber.
• Open-cell synthetic media.
• Washable mesh in selected applications.

Pre-filter media should provide adequate dust-holding capacity without creating excessive pressure drop.

Air Filter Media for Panel Filters

Panel filters may use:

• Flat synthetic media.
• Pleated synthetic media.
• Polyester media.
• Fiberglass media in selected constructions.

The media can be supported by expanded metal, wire mesh or pleat-support structures depending on the filter design.

Air Filter Media for Pleated Filters

Pleated filter media is folded to increase the filtration surface area inside a fixed frame.

Benefits can include:

• Higher media area.
• Higher dust-holding capacity.
• Lower face velocity through the media.
• More compact filter dimensions.

Air Filter Media for Bag Filters

Bag Filter Media may be manufactured from:

• Synthetic fiber.
• Meltblown synthetic media.
• Glass fiber.
• Multi-layer composite media.

Media selection influences:

• Filter efficiency.
• Pressure drop.
• Pocket stability.
• Dust-holding capacity.
• Service life.

Air Filter Media for Fine Filters

Fine filters require media capable of capturing smaller particles while maintaining acceptable airflow resistance.

Possible media include:

• Fine synthetic media.
• Meltblown media.
• Glass-fiber media.
• Composite media.

Air Filter Media for Compact and V-Bank Filters

Compact and V-Bank Filters commonly use mini-pleat media packs.

The media may be:

• Glass fiber.
• Synthetic fine-fiber media.
• Other engineered media depending on the product.

Mini-pleating provides a large effective media area in a relatively compact filter depth.

Air Filter Media for HEPA Filters

HEPA media is engineered for high-efficiency particulate capture.

The media is typically formed into:

• Mini-pleat packs.
• Deep-pleat separator packs.

Media alone does not determine the complete HEPA filter performance. The final assembly must also control:

• Media-pack sealing.
• Frame leakage.
• Gasket leakage.
• Gel-seal integrity.
• Damage during handling.

Air Filter Media for ULPA Filters

ULPA filter media is designed for even higher particulate filtration requirements than typical HEPA applications.

It is commonly used in:

• Semiconductor facilities.
• Microelectronics cleanrooms.
• Advanced FFU systems.

Air Filter Media for Activated Carbon Filters

Gas-phase filter media must provide sufficient adsorbent quantity and contact time for the target contaminant.

Common formats include:

• Carbon-impregnated nonwoven media.
• Carbon foam.
• Granular carbon beds.
• Carbon pellets.
• Rigid carbon panels.

Air Filter Media for Odor Control

Activated carbon media can help reduce selected odors generated by:

• Traffic pollution.
• Food preparation.
• Commercial buildings.
• Industrial processes.
• Selected VOC sources.

Odor is not a single contaminant, so media selection should consider the actual chemical composition whenever possible.

Air Filter Media for Paint Booths

Paint booth systems use different media on the intake and exhaust sides.

Supply-Air Media

Typical supply media include:

• Coarse synthetic pre-filter media.
• Fine synthetic ceiling media.
• Tackified ceiling filter media.

Exhaust Media

Typical exhaust media include:

• Fiberglass paint arrestor media.
• Paper paint media.
• Multi-layer overspray media.

Supply-air media and exhaust paint-arrestor media are not interchangeable because they perform different functions.

Air Filter Media Rolls

Air Filter Media Rolls provide flexible material for on-site or factory cutting.

They are commonly used for:

• Pre Filters.
• FCU Filters.
• Paint Booth Ceiling Filters.
• Paint Booth Floor Filters.
• Custom Filter Pads.

Air Filter Media Pads

Filter media can be pre-cut into pads for faster replacement and more consistent dimensions.

Custom pads may be supplied according to:

• Width.
• Height.
• Thickness.
• Media grade.
• Application.

Air Filter Media Sheets

Filter sheets may be used for:

• Custom fabrication.
• Small ventilation units.
• Equipment intake filters.
• Industrial machinery.

Air Filter Media Thickness

Media thickness influences airflow resistance, dust-holding capacity and application suitability.

Thicker media may provide:

• Greater fiber depth.
• Higher holding capacity.
• More progressive filtration.

However, thickness alone does not determine efficiency.

Progressive Density Air Filter Media

Progressive-Density Media is constructed so fiber density changes through the media depth.

The upstream side may capture larger particles while finer particles penetrate deeper before being retained.

This construction is common in:

• Paint booth ceiling media.
• Fiberglass paint arrestors.
• Selected pre-filter media.

Tackified Air Filter Media

Some filter media is treated with a tackifying agent to improve particle retention.

Tackified media is commonly found in selected:

• Paint booth ceiling filters.
• Dust-control media.
• Progressive-density synthetic filters.

The tackifying treatment should be compatible with the intended application.

Electrostatic Air Filter Media

Some synthetic media uses electrostatic charge to assist particle capture.

Performance can depend on:

• Fiber material.
• Charge stability.
• Airflow.
• Particle type.
• Environmental conditions.

Where stable long-term performance is important, tested filter performance should be reviewed rather than relying only on the presence of electrostatic properties.

Meltblown Air Filter Media

Meltblown Media is manufactured by forming very fine thermoplastic fibers into a nonwoven web.

It may be used in:

• Fine Filters.
• Bag Filters.
• Pleated Filters.
• Composite filtration media.

Nonwoven Air Filter Media

Nonwoven filter media is widely used because fiber diameter, density and layering can be engineered to provide different levels of filtration performance.

Common materials include:

• Polyester.
• Polypropylene.
• Composite synthetic structures.

Glass Fiber vs Synthetic Fine Filter Media

Criteria	Glass Fiber Media	Synthetic Fine Media
Fiber Type	Fine glass fibers	Polymer fibers
Typical Application	Fine / HEPA / ULPA	Fine / Bag / Compact Filters
Moisture Resistance	Depends on binder and construction	Often good depending on polymer
Mechanical Flexibility	Generally more delicate	Can be more robust depending on design
Selection Basis	Efficiency and application	Efficiency, pressure drop and durability

Air Filter Media and ISO 16890

ISO 16890 is widely used for general ventilation filter classification.

Main groups include:

• ISO Coarse.
• ePM10.
• ePM2.5.
• ePM1.

The standard applies to the performance of complete general ventilation filters rather than raw media alone.

Therefore, raw filter media should not automatically be described as a particular ISO 16890 class unless it has been tested as part of an applicable filter configuration.

G4, M5, M6, F7, F8 and F9 Filter Media

Filter media is often marketed using legacy terms such as:

• G4 Filter Media.
• M5 Filter Media.
• M6 Filter Media.
• F7 Filter Media.
• F8 Filter Media.
• F9 Filter Media.

These designations originate from the former EN 779 classification system.

For technically accurate selection, the performance of the finished filter should be confirmed rather than assuming a raw media roll alone guarantees a specific final filter class.

Air Filter Media and EN 1822

EN 1822 is used for high-efficiency air filters including HEPA and ULPA categories.

As with ISO 16890, classification applies to complete filter performance rather than raw media alone.

A roll of high-efficiency glass-fiber media should not automatically be sold as an H13 or H14 finished filter without appropriate filter testing and assembly verification.

Air Filter Media and ISO 29463

ISO 29463 is another standard used for classification and testing of high-efficiency particulate filters.

For critical HEPA or ULPA applications, complete filter test data and integrity should be considered.

Can Raw Media Be Called H13 or H14?

Raw media may have laboratory-level performance suitable for manufacturing H13 or H14 filters, but the final HEPA classification belongs to the complete filter assembly.

Factors affecting finished-filter performance include:

• Media quality.
• Pleating.
• Media damage.
• Sealant.
• Frame sealing.
• Gasket or gel seal.

Air Filter Media Efficiency

Media efficiency depends on:

• Fiber diameter.
• Fiber density.
• Media thickness.
• Electrostatic properties.
• Air velocity.
• Particle size.
• Media construction.

Higher density generally increases filtration but may also increase resistance.

Air Filter Media Pressure Drop

Pressure Drop is one of the most important performance factors when selecting filter media.

Media resistance is influenced by:

• Fiber density.
• Media thickness.
• Air velocity.
• Media area.
• Dust loading.

When raw media is installed inside a complete filter, pleating and effective media area significantly affect final pressure drop.

Media Area and Pressure Drop

A larger effective media area usually lowers the velocity through the media for the same total airflow.

This is why pleated, bag, compact and V-Bank filters can use significantly more media than flat filters.

Dust-Holding Capacity of Air Filter Media

Dust-holding capacity represents how much particulate contamination a filter can retain before reaching a defined operating condition.

It depends on:

• Media depth.
• Fiber structure.
• Media area.
• Particle characteristics.
• Airflow.

Paint-Holding Capacity of Filter Media

For paint booth exhaust filters, Paint-Holding Capacity is particularly important.

Media with higher overspray capacity can help:

• Extend replacement intervals.
• Reduce booth downtime.
• Maintain airflow longer.
• Reduce downstream paint accumulation.

Air Filter Media and Air Velocity

Filter media performance changes with airflow velocity.

Excessive velocity can:

• Increase pressure drop.
• Reduce filter service life.
• Change particulate capture behavior.
• Affect paint overspray capture.

Media should therefore be selected for the actual filter face area and system airflow.

Air Filter Media and Moisture

Moisture can affect certain filter media and supporting materials.

Potential issues include:

• Media deformation.
• Loss of structural strength.
• Binder deterioration.
• Microbial growth on accumulated contamination.
• Higher pressure drop.

Applications with high humidity or condensation should use media and frames suitable for those conditions.

Air Filter Media and Temperature

Every media type has a practical operating-temperature range.

High temperatures may cause:

• Synthetic fiber shrinkage.
• Binder deterioration.
• Adhesive failure.
• Changes in mechanical properties.

Industrial ovens and hot-process systems should use media specifically rated for the operating temperature.

Air Filter Media and Fire Performance

Some projects require filter media with defined flame or fire-performance characteristics.

Applicable requirements depend on:

• Building code.
• Equipment type.
• Paint booth design.
• Industrial process.
• Local fire-safety requirements.

Fire performance should be confirmed from relevant product test documentation rather than inferred from the media material alone.

Air Filter Media for HVAC Systems

HVAC systems may use several media types according to filtration stage.

A typical sequence may include:

• Synthetic coarse media.
• Fine synthetic or glass-fiber media.
• Mini-pleat fine media.
• Carbon media where gas-phase control is required.

Air Filter Media for AHUs

AHUs may contain multiple media technologies within one system.

Examples include:

• Polyester Pre Filter Media.
• Bag Filter Media.
• Fine Filter Media.
• Compact Filter Media.
• V-Bank Filter Media.
• Activated Carbon Media.
• HEPA Media in selected applications.

Air Filter Media for FCUs

FCUs generally require low-resistance media because their fans have limited static-pressure capacity.

Common options include:

• Synthetic fiber pads.
• Washable mesh.
• Low-resistance pleated media.

Air Filter Media for Commercial Buildings

Commercial buildings may use media for:

• Pre filtration.
• Fine particulate filtration.
• PM2.5 control.
• PM1 control.
• Selected odor reduction.

Air Filter Media for Manufacturing Plants

Factories may use air filter media in HVAC systems serving:

• Production areas.
• Warehouses.
• Packaging areas.
• Control rooms.
• Precision manufacturing zones.

Heavy process dust should generally be handled through dedicated process dust collection rather than ordinary HVAC filter media.

Air Filter Media for Hospitals

Healthcare facilities may use:

• Pre-filter media.
• Fine-filter media.
• HEPA media.
• Carbon or molecular media in selected applications.

Media choice depends on the room function and complete healthcare HVAC design.

Air Filter Media for Pharmaceutical Plants

Pharmaceutical plants may require:

• Fine synthetic or glass-fiber media.
• HEPA media.
• ULPA media for selected applications.
• Molecular media.

Filter media alone does not guarantee cleanroom classification or GMP compliance.

Air Filter Media for Food Factories

Food-processing HVAC systems may use:

• Synthetic pre-filter media.
• Fine-filter media.
• HEPA media in selected high-care applications.
• Carbon media for selected odor applications.

Air Filter Media for Semiconductor Plants

Semiconductor facilities require highly controlled filtration media for both particulate and molecular contamination.

Typical media may include:

• Fine glass-fiber media.
• HEPA media.
• ULPA media.
• Activated carbon.
• Specialized chemisorption media.

HEPA and ULPA media do not remove most gaseous airborne molecular contamination, so molecular filtration requires separate media.

Air Filter Media for Data Centers

Data centers may use:

• Fine synthetic media.
• Glass-fiber general ventilation media.
• Carbon media.
• Specialty molecular media in corrosive environments.

Pressure drop is especially important because data-center cooling systems often operate continuously.

Air Filter Media for High Temperature Applications

High-temperature applications require media that maintains structural stability at elevated temperatures.

Suitable materials may include:

• Glass fiber.
• Micro-glass fiber.
• Specialty mineral-fiber media.

The complete filter construction, including frame, sealant and gasket, must also be temperature rated.

Air Filter Media for PM10

Media intended for PM10 control should be evaluated through applicable finished-filter testing.

For general ventilation, ISO 16890 ePM10 classification provides relevant performance information.

Air Filter Media for PM2.5

Fine-filter media can be incorporated into filters designed to reduce PM2.5.

ISO 16890 ePM2.5 or ePM1 data should be reviewed for the finished filter.

Air Filter Media for PM1

Very fine synthetic or glass-fiber media may be used in finished filters classified for ePM1 performance.

Raw media alone should not be assumed to provide a specific ISO 16890 class without appropriate testing.

Replacing media with a visually similar material does not guarantee equivalent filtration performance.

Can Air Filter Media Be Washed?

Only media specifically designed as washable should be cleaned and reused.

Most fine synthetic, Bag, HEPA, ULPA and paint booth ceiling media is intended for replacement rather than washing.

Can Synthetic Filter Media Be Washed?

Some coarse synthetic media is washable, while other synthetic media is disposable.

Washability should be confirmed from the product specification.

Can Fiberglass Filter Media Be Washed?

Fiberglass paint arrestor media and fine glass-fiber filtration media are generally not intended for washing.

Can HEPA Media Be Washed?

No. Standard HEPA media should not be washed because water or mechanical cleaning can damage the fiber structure and compromise filter integrity.

Can Activated Carbon Media Be Washed?

Standard carbon media should generally not be washed. Water can alter adsorption performance and does not restore saturated carbon capacity.

When Should Air Filter Media Be Replaced?

Replacement depends on application.

Indicators may include:

• Excessive pressure drop.
• Heavy dust loading.
• Paint saturation.
• Physical damage.
• Moisture damage.
• Loss of odor-control performance.
• Facility maintenance requirements.

Air Filter Media and Differential Pressure

For particulate filters, differential pressure can help indicate loading.

However, raw media used in thin pads may be monitored differently from assembled Bag, Compact or HEPA Filters.

Carbon Media Replacement

Carbon media saturation may not create a significant increase in pressure drop.

Replacement should instead consider:

• Target contaminant concentration.
• Media quantity.
• Operating time.
• Humidity.
• Temperature.
• Breakthrough monitoring.
• Media analysis where required.

Common Problems with Air Filter Media

Media Has Too Much Pressure Drop

The media may be too dense, installed at excessive face velocity or insufficient in effective area.

Media Loads Too Quickly

Possible causes include:

• High contaminant concentration.
• Insufficient pre-filtration.
• Low media area.
• Incorrect media type.

Media Tears or Deforms

Potential causes include:

• Excessive airflow.
• Insufficient mechanical support.
• Moisture.
• Incorrect installation.

Paint Booth Media Becomes Blocked Quickly

The selected media may have insufficient paint-holding capacity or the spray process may generate unusually high overspray loading.

Carbon Media Does Not Control the Target Gas

The adsorbent may not be chemically suitable for the contaminant.

Raw Media Does Not Achieve the Expected Filter Class

Finished-filter performance depends on the complete assembly and cannot be determined from raw media alone.

How to Extend Air Filter Media Service Life

What Is HEPA Filter Media Made Of?

HEPA media is commonly manufactured from fine glass-fiber material engineered for high particulate filtration efficiency.

Can Raw Filter Media Be Classified as H13 or H14?

The complete filter assembly must satisfy the applicable high-efficiency performance requirements. Raw media performance alone does not guarantee an H13 or H14 finished filter.

What Is Activated Carbon Filter Media?

Activated Carbon Media is adsorbent material used to reduce selected gases, VOCs and odors rather than primarily capturing particulate matter.

Can Carbon Media Remove All Gases?

No. Different gases require different adsorbent properties, and some contaminants require impregnated carbon or other specialty molecular media.

What Is Paint Booth Ceiling Filter Media?

It is usually progressive-density synthetic filter media installed in the ceiling of a spray booth to reduce fine dust and help provide cleaner supply air.

What Is Paint Arrestor Media?

Paint Arrestor Media is exhaust-side filtration material designed to capture paint droplets and overspray.

What Is Filter Media Roll?
