Camfil Pocket Filters Vietnam – Hi-Flo Pocket Filters for AHU & HVAC Systems

Camfil Pocket Filters Vietnam provide high-capacity particulate filtration for Air Handling Units (AHU), HVAC systems, supply-air systems, return-air systems and other General Ventilation applications in commercial and industrial facilities.

Pocket Filters are also commonly known as Bag Filters. Their characteristic multi-pocket construction creates a large filtration-media area within a standard HVAC filter module, allowing the filter to combine particulate-removal performance, dust-holding capacity and manageable pressure drop when correctly selected.

Camfil's current General Ventilation portfolio includes several Pocket Filter configurations, with Hi-Flo being one of its principal product families. Current Camfil Hi-Flo products use optimized pocket geometry and are available in multiple efficiencies according to ISO 16890.

VIETPHAT supports customers requiring Camfil Pocket Filters in Vietnam with product identification, technical selection, replacement matching and quotation based on Camfil article number, ISO 16890 efficiency, dimensions, pocket depth, number of pockets, rated airflow, pressure drop, frame material and application requirements.

What Is a Camfil Pocket Filter?

A Camfil Pocket Filter is an HVAC air filter constructed with multiple flexible filter-media pockets connected to a common header frame.

When air flows through the filter, the pockets expand and provide a much larger effective filtration surface than a flat filter with similar frontal dimensions.

This construction can provide:

• Large filter-media area.
• High dust-holding capacity.
• Fine particulate filtration.
• Longer operating life.
• Suitable airflow for large AHUs.
• Reduced replacement frequency when correctly selected.
• Potentially lower lifecycle cost.

The actual performance depends on the specific Camfil model, ISO 16890 efficiency, dimensions, media area, pocket design, airflow and operating conditions.

Is a Pocket Filter the Same as a Bag Filter?

Yes, in General Ventilation terminology, Pocket Filter and Bag Filter commonly refer to the same type of HVAC filter construction.

Camfil itself describes this product category as “Bag Filters” and notes that they are also called “Pocket Filters.”

Therefore, search terms such as:

• Camfil Pocket Filter.
• Camfil Bag Filter.
• Camfil Filter Bag.
• Camfil Pocket Air Filter.
• Camfil Hi-Flo Filter.
• Camfil Hi-Flo Pocket Filter.

can refer to closely related products within the same General Ventilation category.

Do Not Confuse HVAC Pocket Filters with Industrial Dust Collector Bags

The term “Bag Filter” can also describe long filter bags used inside industrial baghouse dust collectors.

These are different products.

Parameter	HVAC Pocket / Bag Filter	Industrial Baghouse Filter
Main Application	AHU and HVAC	Industrial process dust collection
Construction	Multiple flexible pockets	Long tubular or envelope filter bags
Typical Contamination	Ventilation particulate	High process-dust concentration
Typical Classification	ISO 16890	Application-specific industrial criteria
Example Camfil Family	Hi-Flo	Different industrial dust-collection products

Camfil Hi-Flo Pocket Filters are General Ventilation filters and should not be treated as substitutes for dedicated industrial dust-collection systems.

How Camfil Pocket Filters Work

Air enters through the front face of the filter and is distributed into multiple pockets.

Each pocket contains filtration media. The extended surface created by the pockets allows a large amount of media to fit within the filter module.

Airborne particles are captured as air passes through the media, while cleaned air continues downstream through the AHU or HVAC system.

The performance of the filter depends on:

• Filter-media properties.
• Total media area.
• Pocket geometry.
• Number of pockets.
• Pocket depth.
• Air distribution.
• Face velocity.
• Rated airflow.
• Filter loading.

Why Pocket Geometry Is Important

A Pocket Filter is more than several pieces of media sewn into bags.

Pocket geometry affects how air moves through the entire filtration surface.

A well-designed pocket configuration can help provide:

• Uniform air distribution.
• Effective use of filter media.
• Stable pockets under airflow.
• Controlled pressure drop.
• Improved dust loading.

Camfil specifically highlights optimized pocket design and air distribution within its Hi-Flo product families.

Camfil Hi-Flo Pocket Filters

Camfil Hi-Flo is a major Pocket Filter family designed for HVAC and industrial General Ventilation applications.

Current manufacturer information identifies Hi-Flo as a glass-fibre Bag Filter range with a robust metal header frame.

Important characteristics include:

• Glass-fibre filtration media in the referenced Hi-Flo range.
• Strong metal header frame.
• Multiple filter efficiencies according to ISO 16890.
• Flexible dimensions.
• Multiple pocket configurations.
• Optimized pocket design.
• High dust-holding capacity.
• Low pressure drop in appropriately selected configurations.
• Long operating life.

Camfil Hi-Flo Pocket Design

Camfil's current Hi-Flo design allows different numbers of pockets depending on the required dimensions, efficiency and performance.

Camfil notes that configurations with more pockets can be optimized for lower initial pressure drop and reduced energy consumption, including with shorter pocket lengths.

Configurations with fewer pockets can provide a more economical solution with reduced material use.

This illustrates an important engineering principle:

Two Pocket Filters with identical frontal dimensions and efficiency do not necessarily have identical pressure drop, media area or lifecycle performance.

Camfil Hi-Flo XLS Pocket Filters

Camfil Hi-Flo XLS is another current glass-fibre Pocket Filter range.

The Hi-Flo XLS uses fewer pockets and a molded recycled-plastic frame in the referenced current configuration.

Camfil highlights:

• Low initial pressure drop.
• Flat pressure-drop curve.
• Conical pockets.
• Optimized air distribution.
• Multiple standard sizes.
• ISO 16890 efficiencies.
• Molded recycled-plastic frame.

Camfil Hi-Flo vs Hi-Flo XLS

Parameter	Hi-Flo	Hi-Flo XLS
Filter Type	Pocket / Bag Filter	Pocket / Bag Filter
Media	Glass fibre in referenced range	Glass fibre in referenced range
Frame	Metal / galvanized steel depending model	Molded recycled plastic in referenced range
Pocket Design	Multiple optimized configurations	Conical/tapered pockets
Standard	ISO 16890	ISO 16890
Selection	Application-specific	Application-specific

Neither product should be selected from the family name alone. The exact efficiency, dimensions, airflow and pressure drop should be checked against the specific article number.

Camfil Pocket Filters and ISO 16890

ISO 16890 is the principal current classification framework for General Ventilation air filters.

The standard evaluates performance in relation to particulate fractions including:

• PM10.
• PM2.5.
• PM1.

General Ventilation filters can therefore receive classifications including:

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

Current Camfil Pocket Filters should preferably be specified using their tested ISO 16890 performance.

Camfil ePM10 Pocket Filters

Camfil offers Pocket Filter configurations with ePM10 performance.

For example, current Hi-Flo XLS data include an ePM10 60% configuration.

One manufacturer example is:

Parameter	Example Hi-Flo XLS
ISO 16890	ePM10 60%
Legacy EN 779	M5
Dimensions	592 × 592 × 640 mm
Number of Pockets	6
Airflow	3,400 m³/h
Initial Pressure Drop	40 Pa

This is one current manufacturer example and should not be interpreted as a universal specification for all Camfil Pocket Filters.

Camfil ePM1 Pocket Filters

For applications requiring higher fine-particle efficiency, selected Camfil Pocket Filters are available with ePM1 performance.

Depending on the exact Hi-Flo configuration and current regional portfolio, ePM1 efficiencies can include different performance levels.

When specifying an ePM1 Pocket Filter, always confirm:

• Exact ISO 16890 classification.
• Dimensions.
• Rated airflow.
• Initial pressure drop.
• Pocket depth.
• Number of pockets.
• Article number.

What Does ePM1 Mean?

ePM1 is an ISO 16890 classification related to the filter's tested performance against the PM1 particulate fraction.

It should not be interpreted as:

• Efficiency against every individual particle size.
• HEPA classification.
• Gas-removal efficiency.
• VOC-removal efficiency.
• A guarantee of indoor-air quality by itself.

Camfil M5 Pocket Filters

Older HVAC specifications frequently use the former EN 779 designation M5.

Current Camfil Hi-Flo XLS documentation can still show legacy M5 alongside current ISO 16890 information for reference.

For example, the referenced Hi-Flo XLS ePM10 60% configuration is also shown as M5 under the former EN 779 system.

However, procurement of current filters should preferably use ISO 16890 data where available.

Camfil F7 Pocket Filters Vietnam

Camfil F7 Pocket Filter remains a common search and procurement term in Vietnam because many older AHU specifications were written under EN 779.

F7 is a legacy General Ventilation classification.

When replacing an existing F7 filter, do not rely only on the F7 label.

Identify:

• Original Camfil article number.
• Current ISO 16890 performance.
• Dimensions.
• Pocket depth.
• Number of pockets.
• Airflow.
• Pressure drop.

Camfil F8 Pocket Filters Vietnam

F8 is another legacy EN 779 designation that can appear in older HVAC schedules.

When an F8 Pocket Filter requires replacement, the current ISO 16890 performance of the proposed filter should be checked rather than assuming a universal conversion.

Camfil F9 Pocket Filters Vietnam

Older HVAC systems may also specify F9 Pocket Filters.

F9 represented a higher-efficiency General Ventilation filter under the former EN 779 system.

F9 should not be confused with HEPA H13 or H14.

Can EN 779 Classes Be Directly Converted to ISO 16890?

No universal one-to-one conversion should be assumed.

EN 779 and ISO 16890 use different testing and classification methodologies.

Therefore:

• M5 does not universally equal one specific ePM value.
• F7 does not universally equal one specific ePM1 value.
• F8 does not universally equal one specific ePM1 value.
• F9 does not universally equal HEPA.

The current Camfil datasheet for the exact filter is the preferred reference.

Camfil Pocket Filter Standard Sizes

Camfil identifies 592 × 592 mm as a standard full-module frontal size for its Bag/Pocket Filter category.

However, Pocket Filters are available in many other dimensions.

Common module widths and heights can include approximately:

• 287 mm.
• 490 mm.
• 592 mm.
• 892 mm in selected configurations.

Exact sizes depend on the Camfil product family and article number.

Camfil Pocket Filter Depth

Camfil's general Pocket Filter category currently identifies depths ranging approximately from:

370–670 mm

depending on product.

Individual Hi-Flo and Hi-Flo XLS configurations can use different pocket lengths within or around this range.

Why Pocket Depth Matters

Pocket depth can influence:

• Total media area.
• Initial pressure drop.
• Dust-holding capacity.
• Filter life.
• Required AHU installation space.

A deeper Pocket Filter is not automatically superior. It must physically fit the AHU and operate correctly at the design airflow.

Number of Pockets

The number of pockets can vary significantly between Camfil configurations.

Depending on dimensions and product design, a Pocket Filter may contain:

• 3 pockets.
• 5 pockets.
• 6 pockets.
• 8 pockets.
• 10 pockets.
• 12 pockets.
• Other configurations depending on product.

The pocket count should be recorded when identifying an existing filter.

More Pockets Do Not Automatically Mean Higher Efficiency

The number of pockets primarily affects factors such as media area, airflow distribution, resistance and filter construction.

Efficiency should be determined from the filter's tested ISO 16890 classification.

Therefore:

Number of pockets ≠ efficiency class.

Camfil Pocket Filter Frame Materials

Camfil's current Bag/Pocket Filter category includes frame options such as:

• Galvanized steel.
• Recycled plastic.

The actual frame material depends on the product family.

For example, current premium Hi-Flo products can use a robust metal header frame, while Hi-Flo XLS configurations can use molded recycled plastic.

Camfil Pocket Filter Media

Camfil lists several media technologies within its broader Pocket Filter category, including:

• Glass fibre.
• Synthetic media.
• Glass fibre combined with activated carbon in selected specialty configurations.

Media should therefore be verified from the exact product datasheet rather than assumed from the Pocket Filter construction alone.

Raw Media Does Not Define Complete Filter Efficiency

The performance of a completed Pocket Filter depends on more than the raw filtration material.

It also depends on:

• Media area.
• Pocket construction.
• Seams.
• Frame.
• Air distribution.
• Filter sealing.
• Complete-filter testing.

A piece of glass-fibre media should therefore not automatically be labeled ePM1 simply because it is used in an ePM1 filter.

Camfil Pocket Filter Airflow

Airflow is a critical selection parameter.

Common full-size 592 × 592 mm Camfil Pocket Filter configurations are often designed around approximately 3,400 m³/h, but this is not a universal rating.

For example, current Hi-Flo XLS data show:

Dimensions	Example Rated Airflow
287 × 592 mm	1,700 m³/h
490 × 592 mm	2,800 m³/h
592 × 592 mm	3,400 m³/h

These values are examples for specific configurations and should not be generalized to every Pocket Filter.

Camfil Pocket Filter Pressure Drop

Pressure drop is the resistance created as air passes through the filter.

It is normally expressed in Pascals (Pa).

Pressure drop depends on:

• Filter efficiency.
• Media area.
• Pocket geometry.
• Pocket depth.
• Number of pockets.
• Airflow.
• Dust loading.

Initial Pressure Drop

Initial pressure drop refers to the resistance of a clean filter at a specified airflow.

For example, the current Hi-Flo XLS ePM10 60% configuration at 592 × 592 × 640 mm and 3,400 m³/h is listed by Camfil at approximately 40 Pa initial pressure drop.

A shorter 592 × 592 × 520 mm configuration at the same 3,400 m³/h is listed at approximately 45 Pa.

This demonstrates how pocket depth and media area can affect resistance even when frontal size and efficiency remain similar.

Operating Pressure Drop

As a Pocket Filter captures dust, its pressure drop generally increases.

This increasing resistance affects the fan throughout the filter's operating life.

For this reason, filter evaluation should consider more than the clean-filter pressure drop.

Why Low Pressure Drop Matters

Lower filter resistance at the required efficiency can potentially help:

• Maintain design airflow.
• Reduce fan-energy requirements.
• Maintain cooling performance.
• Maintain heating performance.
• Support required ventilation rates.
• Reduce lifecycle operating cost.

However, the lowest initial pressure drop alone does not automatically identify the best filter.

Camfil Pocket Filters and Energy Consumption

The filter itself does not consume electricity, but the HVAC fan uses energy to overcome its resistance.

For an AHU operating thousands of hours per year, even relatively small differences in average filter pressure drop can influence annual fan-energy consumption.

A lifecycle evaluation can therefore consider:

• Initial pressure drop.
• Average operating pressure drop.
• Fan efficiency.
• Airflow.
• Annual operating hours.
• Filter service life.

Dust-Holding Capacity

One of the principal benefits of Pocket Filter construction is the ability to provide a relatively large filtration surface.

Camfil states that Pocket Filters generally provide high dust-holding capacity and can offer longer service life than filters with less media area.

Actual dust capacity depends on the specific filter design and operating environment.

Camfil Pocket Filters for AHU Systems

Air Handling Units are one of the primary applications for Camfil Pocket Filters.

A typical two-stage filtration concept can be:

Outdoor Air → Pre Filter → Camfil Pocket Filter → Cooling Coil → Fan → Supply Air

The Pre Filter captures larger particulate contamination, while the Pocket Filter provides higher-efficiency filtration downstream.

Camfil Pocket Filters as First or Second Filter Stage

Camfil identifies Bag/Pocket Filters as suitable for first- and second-stage General Ventilation filtration depending on the specific product and required efficiency.

In many AHUs, higher-efficiency Pocket Filters are used as the second stage after a coarse or medium-efficiency Pre Filter.

For example:

Camfil Pre Filter → Camfil Hi-Flo Pocket Filter

Camfil Pocket Filters as HEPA Prefilters

Camfil also identifies Pocket Filters for use as prefilters in HEPA installations.

A conceptual filtration arrangement can be:

Pre Filter → Fine Pocket Filter → HEPA Filter

The Pocket Filter can reduce particulate loading on the more expensive downstream HEPA Filter.

This may help extend HEPA service life when the stages are appropriately selected.

Camfil Pocket Filters for HVAC Systems

Camfil Pocket Filters can be applied to central HVAC systems serving:

• Commercial buildings.
• Office buildings.
• Hotels.
• Shopping centers.
• Factories.
• Hospitals.
• Pharmaceutical facilities.
• Food factories.
• Electronics factories.
• Semiconductor facilities.
• Data centers.
• Cleanroom support systems.
• Warehouses.

Camfil Pocket Filters for Commercial Buildings

Commercial HVAC systems can use Pocket Filters to reduce airborne particulate contamination in supply air.

Applications can include:

• Offices.
• Hotels.
• Shopping malls.
• Airports.
• Schools.
• Universities.
• Retail facilities.
• Public buildings.

Filter efficiency should be selected according to outdoor-air quality, indoor-air requirements and HVAC capability.

Camfil Pocket Filters for Manufacturing Plants

Manufacturing facilities can use Camfil Pocket Filters in central HVAC and factory ventilation systems.

Potential applications include:

• Production halls.
• Assembly areas.
• Warehouses.
• Precision manufacturing.
• Automotive facilities.
• Electronics production.

General HVAC Pocket Filters should not be used as substitutes for dedicated process-dust extraction where high dust concentrations are generated directly by manufacturing processes.

Camfil Pocket Filters for Hospitals

Hospital AHUs can use Pocket Filters as part of multi-stage particulate filtration.

A conceptual configuration may include:

Pre Filter → Fine Pocket Filter → Additional Final Filtration where required

The actual filtration strategy depends on the clinical area, HVAC design and risk requirements.

HEPA filtration is not automatically required in every hospital HVAC zone.

Camfil Pocket Filters for Pharmaceutical Plants

Pharmaceutical facilities can use Pocket Filters upstream of HEPA filtration.

For example:

Pre Filter → Fine Pocket Filter → AHU → HEPA Final Filter

This arrangement can help reduce particulate loading on downstream critical filtration.

However, Pocket Filter efficiency or HEPA class alone does not establish GMP compliance.

Camfil Pocket Filters for Food Factories

Food and beverage HVAC systems can use Pocket Filters to control particulate contamination in supply air.

Selection should consider:

• Hygiene zoning.
• Product exposure.
• Outdoor-air contamination.
• Required air cleanliness.
• Humidity.
• Process conditions.

Heavy flour, sugar, powder or process dust can require dedicated source-capture and industrial dust-control equipment.

Camfil Pocket Filters for Electronics Factories

Electronics manufacturing can use Pocket Filters as intermediate filtration before higher-efficiency terminal stages.

For example:

Pre Filter → Pocket Filter → HEPA / ULPA → Controlled Production Area

Where gaseous Airborne Molecular Contamination is important, separate target-specific molecular filtration may also be required.

Camfil Pocket Filters for Semiconductor Plants

Semiconductor Make-Up Air Units and AHUs can use Pocket Filters for upstream particulate control.

However:

Pocket Filter ≠ HEPA ≠ ULPA ≠ Molecular Filter.

Each filtration stage performs a different contamination-control function.

Camfil Pocket Filters for Data Centers

Data centers can use Pocket Filters in AHUs, Make-Up Air Units and outdoor-air systems to reduce particulate contamination.

Important selection parameters include:

• Outdoor particulate concentration.
• Economizer operation.
• ISO 16890 efficiency.
• Airflow.
• Pressure drop.
• Operating hours.
• Energy consumption.

Where corrosive gaseous contaminants are a concern, molecular filtration should be evaluated separately.

Camfil Pocket Filters for Cleanrooms

Pocket Filters can be used upstream of final cleanroom filtration.

A typical concept is:

Pre Filter → Fine Pocket Filter → AHU → HEPA / ULPA → Cleanroom

The Pocket Filter helps protect downstream high-efficiency filters.

The Pocket Filter class alone does not define the ISO 14644 cleanroom classification.

Camfil Pocket Filter vs Pre Filter

Parameter	Typical Pre Filter	Fine Pocket Filter
Typical Position	First stage	Second stage
Main Function	Coarse-particle control	Higher-efficiency particulate control
Media Area	Usually lower	Generally larger
Protects	Fine filters / HVAC	Downstream equipment / HEPA where installed

Camfil Pocket Filter vs Panel Filter

Parameter	Panel Filter	Pocket Filter
Construction	Flat or pleated panel	Multiple flexible pockets
Installation Depth	Compact	Greater depth required
Media Area	Product-dependent	Generally high
Dust Capacity	Product-dependent	Can be high
Typical Role	Pre / General Filtration	General / Fine Filtration

Camfil Pocket Filter vs Compact Filter

Parameter	Pocket Filter	Compact Filter

Camfil Pocket Filter vs HEPA Filter

Parameter	Pocket Filter	HEPA Filter
Primary Standard	ISO 16890	EN 1822 / ISO 29463
Typical Application	General Ventilation	Critical high-efficiency filtration
Example Classification	ePM10 / ePM2.5 / ePM1	H13 / H14
Construction	Flexible pockets	High-area pleated element
Gas Removal	Not normally	No

Is an ePM1 Pocket Filter a HEPA Filter?

No.

An ePM1 Pocket Filter is a General Ventilation filter classified according to ISO 16890.

A HEPA Filter is evaluated according to standards such as EN 1822 or ISO 29463.

Do not describe an ePM1 Pocket Filter as H13 or H14 unless the complete filter has actually been tested and classified accordingly.

Can Camfil Pocket Filters Remove PM2.5?

Performance against fine particulate matter depends on the exact ISO 16890 classification.

Do not assume identical PM2.5 performance for every Pocket Filter.

Where PM2.5 control is important, specify an appropriate documented ISO 16890 efficiency.

Can Camfil Pocket Filters Remove PM1?

Selected Camfil Pocket Filters have documented ePM1 performance.

The exact ePM1 efficiency should be verified from the individual product datasheet.

ePM1 performance should not be inferred simply because a filter has multiple pockets or was historically classified F7, F8 or F9.

Can Camfil Pocket Filters Remove Odors?

Standard particulate Pocket Filters are not primarily designed to remove gases or odors.

For applications involving:

• Odors.
• VOCs.
• Corrosive gases.
• Acid gases.
• Basic gases.
• Other molecular contaminants.

an appropriate Camfil molecular filtration solution should be evaluated.

Pocket Filter vs Activated Carbon Filter

The technologies perform different functions.

Filter	Primary Function
Pocket Filter	Particulate filtration
Activated Carbon / Molecular Filter	Selected gaseous contaminants and odors
HEPA Filter	Very high-efficiency particulate filtration

A Pocket Filter does not replace molecular filtration, and activated carbon does not replace particulate filtration.

How Long Does a Camfil Pocket Filter Last?

There is no universal service-life interval.

Filter life depends on:

• Outdoor-air pollution.
• Upstream Pre Filter.
• Particle concentration.
• Airflow.
• Operating hours.
• Media area.
• Pocket depth.
• Dust-holding capacity.
• Final pressure-drop criterion.
• Environmental conditions.

Two identical Camfil Pocket Filters can therefore have very different service lives in different installations.

When Should a Camfil Pocket Filter Be Replaced?

Replacement decisions can consider:

• Differential pressure.
• System airflow.
• Physical condition.
• Hygiene requirements.
• Operating history.
• Manufacturer guidance.
• Facility maintenance requirements.

Where practical, differential-pressure monitoring is preferable to relying solely on an arbitrary fixed replacement interval.

Can Camfil Pocket Filters Be Washed?

Conventional Fine Pocket Filters should not automatically be treated as washable.

Only filters explicitly designed and documented by the manufacturer as washable should be washed and reused.

Improper washing can damage:

• Filter fibres.
• Pocket seams.
• Media structure.
• Frame.
• Filtration performance.

Can Pocket Filters Be Cleaned with Compressed Air?

Compressed-air cleaning should not automatically be applied to disposable Fine Pocket Filters.

High-pressure air can damage media and redistribute captured contamination.

For conventional disposable Pocket Filters, condition-based replacement according to manufacturer and facility requirements is generally more appropriate.

Camfil Pocket Filter Replacement Vietnam

For an accurate replacement, collect the following information from the existing filter:

• Camfil product family.
• Camfil article number.
• ISO 16890 efficiency.
• Legacy EN 779 class if shown.
• Width.
• Height.
• Pocket depth.
• Number of pockets.
• Rated airflow.
• Initial pressure drop.
• Frame material.
• Quantity.

How to Measure a Camfil Pocket Filter

Measure:

Width × Height × Pocket Depth

in millimetres.

Also count the number of pockets.

For example:

592 × 592 × 640 mm – 6 pockets

provides much more useful identification information than simply requesting a “592 × 592 Pocket Filter.”

Nominal Dimensions vs Actual Dimensions

Nominal HVAC filter sizes and actual manufactured dimensions can differ slightly.

Always verify:

• Existing filter label.
• Actual measurements.
• Filter-bank opening.
• Camfil article number.

An incorrectly sized filter can create bypass around the filter and reduce effective system filtration.

Dimensions Alone Are Not Enough

Two Pocket Filters with identical W × H × D dimensions can differ significantly in:

• ISO 16890 efficiency.
• Media type.
• Media area.
• Number of pockets.
• Airflow.
• Initial pressure drop.
• Dust-holding capacity.
• Expected service life.

Replacement selection should never rely solely on external dimensions.

How to Identify an Unknown Camfil Pocket Filter

If the original article number is unknown, provide:

• Photograph of the complete filter.
• Close-up photograph of the label.
• Camfil product code if visible.
• Actual dimensions.
• Pocket depth.
• Number of pockets.
• Existing efficiency.
• AHU model where available.
• Quantity.

This information can help identify the appropriate replacement configuration.

Replacing an Old Camfil M5, F7, F8 or F9 Pocket Filter

Older Camfil filters can potentially be identified from:

• Old article number.
• Filter label.
• Previous purchase order.
• Old Camfil datasheet.
• AHU specification.
• Dimensions.
• Legacy EN 779 class.
• Airflow.
• Pressure drop.

Where possible, the proposed replacement should then be specified using current ISO 16890 performance.

Can Another Brand Replace a Camfil Pocket Filter?

A technically compatible alternative can be evaluated where brand substitution is permitted.

Compare:

• ISO 16890 efficiency.
• Actual dimensions.
• Pocket depth.
• Number of pockets.
• Rated airflow.
• Initial pressure drop.
• Recommended final pressure drop.
• Media type.
• Frame.
• Operating conditions.

The same size and legacy F7/F8/F9 designation do not automatically establish equivalent performance.

Can a Higher-Efficiency Pocket Filter Replace the Existing Filter?

Potentially, but the HVAC system should be evaluated before upgrading.

A higher-efficiency filter can have different resistance characteristics.

Check:

• Existing filter pressure drop.
• Proposed filter pressure drop.
• Required airflow.
• Available fan static pressure.
• AHU fan curve.
• Cooling capacity.
• Heating capacity.
• Ventilation requirements.
• Energy impact.

An efficiency upgrade that causes excessive resistance can reduce system airflow.

Camfil Pocket Filter Lifecycle Cost

Filter purchasing decisions should not be based only on unit price.

Lifecycle cost can include:

• Filter purchase price.
• Average pressure drop.
• Fan-energy consumption.
• Dust-holding capacity.
• Service life.
• Replacement frequency.
• Maintenance labor.
• Disposal cost.
• Impact on downstream HVAC cleanliness.

A filter with a higher initial purchase price can potentially have a lower total operating cost if it provides suitable pressure-drop and service-life performance.

How to Select Camfil Pocket Filters Vietnam

1. Identify the Existing Camfil Filter

Record the product family and article number where available.

2. Determine Required Efficiency

Use current ISO 16890 performance wherever possible.

3. Measure Width and Height

Measure the actual filter frontal dimensions.

4. Measure Pocket Depth

Confirm that the selected depth fits the AHU.

5. Count the Pockets

Record the number of pockets for accurate replacement matching.

6. Confirm Rated Airflow

Provide airflow in m³/h.

7. Check Initial Pressure Drop

Compare filter resistance at the required airflow.

8. Identify the Upstream Filter

Appropriate Pre Filtration can influence Pocket Filter loading and service life.

9. Identify the Application

AHU, commercial building, factory, hospital, pharmaceutical, food, electronics, data center, cleanroom or another application.

10. Confirm Quantity

Provide quantity for each required size and efficiency.

No universal one-to-one conversion should be assumed because EN 779 and ISO 16890 use different test and classification methodologies.

Can Camfil Pocket Filters Be Used in AHUs?

Yes. AHU and HVAC General Ventilation are primary applications for Camfil Pocket Filters.

Can Camfil Pocket Filters Be Used Before HEPA Filters?

Yes. Appropriately selected Pocket Filters can be used as upstream filtration to reduce particulate loading on downstream HEPA Filters.

Can Camfil Pocket Filters Remove Odors?

Standard particulate Pocket Filters are not primarily designed for gas or odor removal. Appropriate molecular filtration should be evaluated for those contaminants.

Can Camfil Pocket Filters Be Washed?

Only products explicitly designed and documented as washable should be washed. Conventional Fine Pocket Filters should generally be treated according to their disposable-filter maintenance instructions.

How Often Should Camfil Pocket Filters Be Replaced?

There is no universal interval. Differential pressure, airflow, dust loading, physical condition, operating hours and manufacturer recommendations should be considered.

Can Another Brand Replace a Camfil Pocket Filter?

A technically compatible alternative can be evaluated where substitution is allowed, but efficiency, dimensions, pocket depth, number of pockets, airflow, pressure drop, media and application should all be compared.

What Information Is Needed for a Camfil Pocket Filter Quotation?

Provide the Camfil model or article number, ISO 16890 efficiency, dimensions, pocket depth, number of pockets, airflow, pressure drop, application and quantity.
