Camfil High Efficiency Air Filters Vietnam – ePM1, HEPA H13 & H14 Filters

Camfil High Efficiency Air Filters Vietnam provide advanced particulate filtration solutions for AHU, HVAC, cleanrooms, pharmaceutical plants, hospitals, laboratories, electronics factories, semiconductor facilities, food production, data centers, commercial buildings and other contamination-sensitive environments.

In air filtration, the term high efficiency air filter should not be treated as one specific filter class. Depending on the application, Camfil high-efficiency filtration can range from ISO 16890 ePM1 general ventilation filters to EPA, HEPA H13, HEPA H14 and ULPA filtration for more demanding contamination-control applications.

Relevant Camfil product families include Opakfil ES for energy-efficient ePM1 filtration in AHU and HVAC systems, Absolute V for high-airflow EPA/HEPA final filtration, and Megalam for terminal HEPA/ULPA cleanroom applications.

VIETPHAT supports customers requiring Camfil High Efficiency Air Filters in Vietnam with product identification, technical selection, replacement matching and quotation based on filtration efficiency, dimensions, airflow, pressure drop, media, frame, gasket or gel seal, installation position and application.

What Are Camfil High Efficiency Air Filters?

Camfil high-efficiency air filters are designed to provide greater particulate removal performance than basic coarse or prefiltration stages.

Depending on the required air quality, this category may include:

• ISO 16890 ePM1 filters.
• High-efficiency bag and pocket filters.
• Compact V-Bank filters.
• EPA filters.
• HEPA H13 filters.
• HEPA H14 filters.
• ULPA filters.

The correct filter should be selected according to the required performance standard rather than simply specifying “high efficiency.”

Camfil High Efficiency Air Filter Classification

Filtration Level	Typical Standard	Typical Camfil Product Direction	Typical Application
ePM10	ISO 16890	Opakfil ES	General HVAC
ePM1 60%	ISO 16890	Opakfil ES	High-efficiency AHU/HVAC
ePM1 70%	ISO 16890	Opakfil ES	Fine particulate control
ePM1 80%	ISO 16890	Opakfil ES	Higher-efficiency HVAC
E10–E12	EN 1822 / ISO 29463	Selected Absolute products	EPA final filtration
H13	EN 1822 / ISO 29463	Absolute / Megalam	HEPA applications
H14	EN 1822 / ISO 29463	Absolute / Megalam	Critical HEPA applications
ULPA	EN 1822 / ISO 29463	Selected Megalam products	Advanced cleanrooms / semiconductor

ISO 16890 High Efficiency Air Filters

For General Ventilation applications, current air-filter specifications commonly use ISO 16890.

The standard evaluates filtration performance against particulate fractions including:

• ePM10.
• ePM2.5.
• ePM1.

For higher-efficiency HVAC filtration, ePM1 performance is particularly relevant because it describes filtration effectiveness against the PM1 particle-size fraction.

However, ePM1 does not mean HEPA.

Camfil ePM1 High Efficiency Air Filters

Camfil provides multiple ePM1 filter configurations for higher-efficiency General Ventilation applications.

A major example is the Camfil Opakfil ES compact V-Bank filter family.

Current configurations include:

• ePM1 60%.
• ePM1 70%.
• ePM1 80%.

These filters can be used where higher fine-particle filtration is required without necessarily moving to HEPA filtration.

Camfil Opakfil ES

Camfil Opakfil ES is a compact V-Bank air filter developed for high-efficiency General Ventilation applications.

Important characteristics of the current product family include:

• ISO 16890 ePM1 and ePM10 configurations.
• Low initial pressure drop.
• High dust-holding capacity.
• Large effective media area.
• Aerodynamic radial V geometry.
• Glass-fibre filter media.
• Rigid ABS frame in referenced current configurations.
• Compact installation depth.
• High airflow capability.

Camfil Opakfil ES ePM1 60%

A current full-size Opakfil ES ePM1 60% configuration has the following reference data:

Parameter	Reference Value
ISO 16890	ePM1 60%
Legacy EN 779	F7
Dimensions	592 × 592 × 296 mm
Rated Airflow	3400 m³/h
Initial Pressure Drop	65 Pa
Filter Media	Glass Fibre
Frame	ABS

The values above apply to the referenced configuration and should not automatically be applied to every Opakfil ES size.

Camfil Opakfil ES ePM1 70%

A current 592 × 592 × 296 mm Opakfil ES ePM1 70% configuration provides approximately:

• ISO 16890: ePM1 70%.
• Legacy EN 779: F8.
• Rated airflow: 3400 m³/h.
• Initial pressure drop: 75 Pa.

This configuration can be considered where higher PM1 filtration is required and the HVAC system can accommodate its airflow resistance.

Camfil Opakfil ES ePM1 80%

A current 592 × 592 × 296 mm Opakfil ES ePM1 80% configuration provides approximately:

• ISO 16890: ePM1 80%.
• Legacy EN 779: F9.
• Rated airflow: 3400 m³/h.
• Initial pressure drop: 90 Pa.

This example demonstrates why filtration efficiency and pressure drop should be evaluated together.

Camfil ePM1 60% vs ePM1 70% vs ePM1 80%

Filter	ISO 16890	Legacy Class	Example Airflow	Example Initial DP
Opakfil ES 0160	ePM1 60%	F7	3400 m³/h	65 Pa
Opakfil ES 0170	ePM1 70%	F8	3400 m³/h	75 Pa
Opakfil ES 0180	ePM1 80%	F9	3400 m³/h	90 Pa

The referenced examples use a 592 × 592 × 296 mm filter.

Legacy F7, F8 and F9 classes originate from the former EN 779 system. There is no universal exact one-to-one conversion between legacy EN 779 classes and ISO 16890 performance, so current ISO 16890 test data should be used when specifying new filters.

Is Camfil ePM1 a HEPA Filter?

No.

ISO 16890 ePM1 filters and HEPA filters belong to different classification systems.

General Ventilation filters:

ISO 16890 → ePM10 / ePM2.5 / ePM1

High-efficiency EPA/HEPA/ULPA filters:

EN 1822 / ISO 29463 → EPA / HEPA / ULPA

Therefore:

ePM1 ≠ HEPA.

Is F9 a HEPA Filter?

No.

F9 is a legacy fine-filter classification under the former EN 779 system.

H13 and H14 are HEPA classifications.

Therefore:

F9 ≠ H13 ≠ H14.

Camfil HEPA High Efficiency Air Filters

When the application requires particulate filtration beyond General Ventilation ePM1 performance, Camfil provides EPA, HEPA and ULPA filtration products.

Relevant families include:

• Absolute V.
• Absolute compact HEPA filters.
• Megalam HEPA panels.
• Megalam ULPA panels.

Camfil Absolute V

Camfil Absolute V is a V-shaped high-efficiency final-filter family designed for applications requiring very high airflow with relatively low pressure drop.

Current Camfil information identifies Absolute V configurations covering:

E10 to H14

with MPPS efficiencies across the family ranging from approximately:

85% to 99.995%.

The exact efficiency depends on the selected filter class.

What Is MPPS?

MPPS means Most Penetrating Particle Size.

It represents the particle-size range at which a particular filter is most penetrable under the relevant test conditions.

HEPA classification under EN 1822 evaluates filter performance around this challenging particle-size range rather than relying only on a generic particle size.

Camfil H13 HEPA Filters

Under EN 1822, an H13 HEPA filter has an overall efficiency of at least:

99.95% at MPPS.

Potential applications include:

• Cleanrooms.
• Pharmaceutical facilities.
• Hospitals.
• Laboratories.
• Electronics production.
• Selected food-production areas.
• Critical manufacturing processes.

Camfil H14 HEPA Filters

H14 provides a higher HEPA filtration level.

Under EN 1822, H14 has an overall efficiency of at least:

99.995% at MPPS.

H14 may be specified for more contamination-sensitive environments where the process or engineering specification requires this filtration level.

Camfil H13 vs H14 High Efficiency Filters

Parameter	H13	H14
Category	HEPA	HEPA
Overall MPPS Efficiency	≥99.95%	≥99.995%
Typical Application	Critical clean-air systems	More demanding critical applications
Pressure Drop	Product-dependent	Product-dependent
Standard	EN 1822 / ISO 29463 as applicable	EN 1822 / ISO 29463 as applicable

Is H14 Always Better Than H13?

H14 provides higher particulate filtration efficiency, but it should not automatically be selected for every application.

Engineering considerations include:

• Required cleanliness.
• Contamination-control strategy.
• Design airflow.
• Available fan static pressure.
• Filter pressure drop.
• Housing compatibility.
• Seal configuration.
• Energy consumption.
• Testing and validation requirements.

The appropriate filter is the one that meets the required performance while remaining compatible with the complete air-handling system.

Camfil Absolute V High Airflow HEPA Filter

Absolute V is designed for high-airflow final filtration.

Camfil currently identifies the family for very high airflow applications, including configurations exceeding approximately 3400 m³/h depending on the selected model.

The V-shaped media arrangement increases effective media area within a compact filter housing.

Camfil Absolute V Construction

Current Camfil information identifies features including:

• V-shaped filter packs.
• Controlled Media Spacing technology.
• Hot-melt separators.
• Rigid self-supported media packs.
• Seamless polyurethane gasket on referenced configurations.
• High airflow capability.
• Low-pressure-drop design.

These characteristics are intended to provide controlled airflow through the media and minimize bypass when the filter is correctly installed in a compatible housing.

Camfil Absolute V Applications

Potential applications include:

• Make-up air units.
• Recirculation units.
• Air-conditioning systems.
• Final HEPA filtration.
• Cleanroom air systems.
• Protection of terminal HEPA filters.
• Selected exhaust-air applications.

Camfil Megalam High Efficiency Air Filters

Camfil Megalam represents another important category of high-efficiency filtration.

Megalam products are panel-type HEPA and ULPA filters intended primarily for terminal clean-air applications.

Potential applications include:

• Cleanroom ceilings.
• Terminal HEPA housings.
• Laminar-flow systems.
• Unidirectional airflow systems.
• Clean benches.
• Pharmaceutical manufacturing.
• Electronics production.
• Semiconductor manufacturing.

Opakfil ES vs Absolute V vs Megalam

Product Family	Primary Filtration Level	Typical Position	Typical Application
Opakfil ES	ISO 16890 ePM	AHU fine/final general ventilation stage	HVAC / AHU
Absolute V	EPA / HEPA	High-efficiency final stage	AHU / MAU / Critical systems
Megalam	HEPA / ULPA	Terminal filtration	Cleanrooms / Pharma / Semiconductor

High Efficiency Filter vs HEPA Filter

The terms should not automatically be used interchangeably.

Filter	Classification	HEPA?
Opakfil ES ePM1 60%	ISO 16890	No
Opakfil ES ePM1 70%	ISO 16890	No
Opakfil ES ePM1 80%	ISO 16890	No
Absolute V E10-E12	EPA	No
Absolute V H13	HEPA	Yes
Absolute V H14	HEPA	Yes

Camfil High Efficiency Filters for AHU

AHU systems are one of the main applications for high-efficiency air filtration.

A typical multi-stage arrangement can be:

Outdoor Air → Prefilter → ePM1 High Efficiency Filter → Coil → Fan → Supply Air

For critical applications:

Prefilter → ePM1 Filter → HEPA → Controlled Environment

The exact sequence depends on the required air quality and AHU configuration.

Why Use a Prefilter?

High-efficiency filters should generally be protected from unnecessary coarse-particle loading where practical.

An upstream prefilter can capture larger contaminants before they reach the fine or HEPA stage.

Potential benefits include:

• Reduced downstream dust loading.
• Longer high-efficiency filter life.
• Reduced replacement frequency.
• Cleaner coils.
• Cleaner fans.
• More stable system operation.

Camfil Multi-Stage Filtration

A conceptual Camfil filtration train may include:

Camfil Panel Prefilter → Camfil Opakfil ES → Camfil Absolute / Megalam HEPA

Stage	Primary Function
Panel Prefilter	Capture coarse particles
Opakfil ES	Fine ePM1 particulate filtration
Absolute / Megalam	HEPA final filtration where required

This is a conceptual example. Actual filtration stages should be selected according to the specific system and contamination-control requirements.

Camfil High Efficiency Filters for HVAC Systems

Applications can include:

• Central air-conditioning systems.
• AHUs.
• Make-up air units.
• Recirculation systems.
• Commercial ventilation.
• Industrial ventilation.

For many General Ventilation systems, an appropriate ePM1 filter may provide the required performance without introducing HEPA-level pressure drop and sealing requirements.

Camfil High Efficiency Filters for Cleanrooms

Cleanroom air systems commonly use multiple filtration stages.

A possible arrangement is:

Prefilter → ePM1 Filter → HEPA / ULPA → Cleanroom

The upstream filters help reduce loading on expensive terminal HEPA or ULPA filters.

HEPA or ULPA filter class alone does not determine ISO 14644 cleanroom classification.

Room classification depends on the performance of the complete controlled environment.

Camfil High Efficiency Filters for Pharmaceutical Plants

Pharmaceutical facilities may use high-efficiency filtration at multiple stages of the HVAC system.

Depending on process requirements, filtration may include:

• Prefilters.
• ePM1 fine filters.
• H13 HEPA.
• H14 HEPA.
• Specialized exhaust filtration.

However, H13 or H14 filtration alone does not establish GMP compliance.

Pharmaceutical HVAC design also requires consideration of:

• Cleanroom classification.
• Pressure cascade.
• Airflow pattern.
• Temperature.
• Humidity.
• Process contamination risks.
• Qualification and validation.

Camfil High Efficiency Filters for Hospitals

Healthcare facilities can use different filtration levels according to room function and infection-control requirements.

A conceptual sequence may include:

Prefilter → ePM1 Filter → HEPA where required

HEPA filtration should not automatically be specified for every hospital area.

The required filtration level should follow the applicable healthcare HVAC design criteria for each space.

Camfil High Efficiency Filters for Operating Rooms

Operating-room air quality depends on more than the filter alone.

Important considerations include:

• Filtration efficiency.
• Airflow distribution.
• Room pressure.
• Supply and exhaust balance.
• Temperature and humidity.
• Filter sealing.
• System integrity.
• Maintenance.

A HEPA filter does not itself create positive room pressure; pressure is produced by the balance between supply, return and exhaust airflow.

Camfil High Efficiency Filters for Electronics Factories

Electronics manufacturing can require high levels of particulate control to protect sensitive processes and products.

Depending on the production environment, filtration may include:

• ePM1 HVAC filters.
• HEPA filters.
• ULPA filters.
• Molecular filters.

Each technology addresses a different contamination-control requirement.

Camfil High Efficiency Filters for Semiconductor Plants

Semiconductor manufacturing requires a clear distinction between particulate filtration and airborne molecular contamination control.

Technology	Primary Function
ePM1	Fine particulate filtration
HEPA	High-efficiency particulate filtration
ULPA	Ultra-high-efficiency particulate filtration
Molecular Filter	Target-specific gaseous/AMC filtration

HEPA and ULPA filters should not be expected to replace molecular filters for gaseous airborne molecular contamination.

Camfil High Efficiency Filters for Food Factories

Food factories may use high-efficiency supply-air filtration according to process exposure and hygiene zoning.

Applications can include:

• Production rooms.
• Packaging areas.
• High-care areas.
• Ingredient preparation.
• Make-up air systems.
• Controlled production environments.

There is no universal requirement that every food-production area use HEPA filtration.

Camfil High Efficiency Filters for Data Centers

Data-center filtration should balance particulate control against airflow and cooling-energy requirements.

Important factors include:

• Outdoor particulate concentration.
• Economizer operation.
• Cooling architecture.
• Required airflow.
• Fan static pressure.
• Filter pressure drop.
• Energy consumption.

HEPA filtration is not automatically required for every data center.

Camfil High Efficiency Filters for Manufacturing Plants

High-efficiency filters can be used in factory AHUs to improve particulate control in:

• Production areas.
• Control rooms.
• Packaging areas.
• Quality-control rooms.
• Equipment rooms.
• Selected process-support areas.

General HVAC filters are not a replacement for dedicated industrial dust collectors, cartridge collectors, baghouses, fume extraction or mist-control equipment where process emissions require source capture.

Do High Efficiency Filters Remove VOCs and Odors?

Conventional ePM1, HEPA and ULPA filters are primarily particulate filters.

They should not be expected to provide universal removal of:

• VOCs.
• Odors.
• Acid gases.
• Alkaline gases.
• Corrosive gases.

These contaminants may require activated carbon or other target-specific molecular filtration media.

High Efficiency Filter vs Activated Carbon Filter

Filter Type	Main Target
ePM1	Fine particles
HEPA	Very fine particulate contamination
ULPA	Ultra-high-efficiency particulate control
Activated Carbon	Selected gases, odors and VOCs
Specialty Molecular Media	Target-specific gaseous contaminants

Camfil High Efficiency Filter Pressure Drop

Pressure drop is one of the most important parameters when selecting a high-efficiency filter.

The fan must overcome filter resistance to maintain design airflow.

Important values include:

• Initial pressure drop.
• Operating pressure drop.
• Recommended final pressure drop.
• Average pressure drop during service life.

Why Low Pressure Drop Matters

Air filters do not normally consume electricity directly, but their resistance affects fan energy.

Lower average filter pressure drop can help reduce fan-energy requirements when filtration efficiency and other system requirements are also satisfied.

This is why filter evaluation should consider both:

Filtration Performance + Energy Performance

Can I Upgrade F7 to F9 or ePM1 80%?

Potentially, but the HVAC system should be checked before increasing filtration efficiency.

Review:

• Current airflow.
• Existing filter pressure drop.
• New filter pressure drop.
• Available fan static pressure.
• Required ventilation rate.
• Heating and cooling performance.

Higher filtration efficiency should not result in unacceptable reduction of system airflow.

Can I Upgrade an ePM1 Filter to HEPA?

This is a much more significant change than replacing one General Ventilation filter with another.

A HEPA retrofit may require evaluation of:

• Fan static pressure.
• Filter housing.
• Mechanical strength.
• Gasket or gel-seal design.
• Bypass leakage.
• Airflow.
• Filter-access arrangement.
• Integrity testing.

A HEPA filter should not simply be inserted into an existing HVAC system because the external dimensions appear compatible.

High Efficiency Filter Sealing

As filter efficiency increases, bypass control becomes increasingly important.

Air leaking around the filter frame is not filtered by the media.

Check:

• Housing condition.
• Filter dimensions.
• Gasket condition.
• Gasket compression.
• Clamping mechanism.
• Frame alignment.
• Gel-seal compatibility where applicable.

Gasket Seal vs Gel Seal

Gasket-seal filters rely on compression between the gasket and the housing sealing surface.

Gel-seal filters typically interface with a knife-edge housing that penetrates a gel channel.

The replacement filter must match the existing housing.

Similar external dimensions do not mean that gasket and gel-seal filters are interchangeable.

Factory HEPA Testing and Installed Integrity Testing

Factory testing verifies the filter under defined manufacturing test conditions.

For critical applications, installed integrity testing may also be required after installation.

This can help evaluate potential leakage through:

• Filter media.
• Filter frame.
• Gasket or gel seal.
• Housing interface.
• Installation defects.

Factory certification and installed integrity testing should therefore not be treated as the same activity.

When Should Camfil High Efficiency Filters Be Replaced?

There is no universal replacement interval applicable to every installation.

Service life depends on:

• Airborne particulate concentration.
• Operating hours.
• Airflow.
• Upstream filtration.
• Filter media area.
• Pressure-drop development.
• Application requirements.

Where practical, differential-pressure monitoring is preferable to relying only on a fixed calendar interval.

Can Camfil High Efficiency Filters Be Washed?

Conventional fine, compact, HEPA and ULPA filters should generally be considered disposable unless the exact product is specifically designed and documented as washable.

Washing can damage:

• Fine filter fibres.
• Pleat geometry.
• Separators.
• Sealants.
• Gaskets.

It can also change tested filtration performance.

Can High Efficiency Filters Be Cleaned with Compressed Air?

Compressed-air cleaning should not be used as a generic regeneration method for disposable high-efficiency filters.

High-pressure air can damage fine media and does not reliably restore original tested performance.

Camfil High Efficiency Replacement Filters Vietnam

For replacement identification, provide:

• Camfil product name.
• Article number.
• Efficiency classification.
• Applicable test standard.
• Width × height × depth.
• Rated airflow.
• Initial pressure drop.
• Frame material.
• Gasket or gel-seal configuration.
• Application.
• Quantity.

Why Filter Dimensions Alone Are Not Enough

Two high-efficiency filters with identical dimensions can have different:

• Efficiency.
• Pressure drop.
• Media area.
• Airflow rating.
• Frame construction.
• Seal configuration.
• Testing requirements.

For this reason, dimensions alone should not be used to identify a technically equivalent replacement.

How to Identify an Unknown Camfil Filter

If the original article number cannot be read, provide:

• Photo of the complete filter.
• Close-up photo of the label.
• Actual dimensions.
• Efficiency information.
• Frame material.
• Gasket or gel-seal position.
• AHU or equipment model.
• Application.
• Quantity.

Camfil High Efficiency Filter Lifecycle Cost

Filter selection should consider more than purchase price.

Lifecycle cost can include:

• Initial filter cost.
• Average pressure drop.
• Fan energy.
• Service life.
• Replacement frequency.
• Maintenance labor.
• Disposal cost.
• Downstream-filter protection.
• System downtime.
