Camfil High Efficiency Air Filters Vietnam – HEPA, ULPA and Fine Filtration Solutions

Camfil High Efficiency Air Filters Vietnam covers advanced particulate filtration solutions for industrial HVAC systems, air handling units, cleanrooms, pharmaceutical manufacturing, electronics production and other facilities requiring controlled air quality.

VIETPHAT supports customers in Vietnam with Camfil filter selection, product identification, technical specification matching, replacement filter inquiries and quotations.

The product range includes high-efficiency general ventilation filters such as Hi-Flo and Opakfil, as well as HEPA and ULPA product families such as Absolute and Megalam.

Choosing the appropriate filter requires a clear understanding of the required filtration efficiency, airflow, pressure drop, installation conditions and applicable technical standards.

1. What Are High-Efficiency Air Filters?

High-efficiency air filters are designed to remove airborne particles according to specified performance requirements. However, the term "high efficiency" can refer to different filter categories.

In general ventilation, high-efficiency filters may be classified under ISO 16890, including products with ePM1 performance ratings.

For applications requiring substantially higher particle-removal efficiency, HEPA and ULPA filters are classified and tested under standards such as EN 1822 and ISO 29463.

These standards measure different aspects of filtration performance. An ePM1 filter must not be described as equivalent to an H13 or H14 HEPA filter.

2. Camfil High-Efficiency Air Filter Product Range

Product Family	Filter Category	Typical Applications
Hi-Flo	High-efficiency general ventilation bag filter	Industrial and commercial HVAC
Opakfil	Compact V-Bank fine filter	AHU, HVAC and cleanroom prefiltration
Absolute	EPA/HEPA, depending on configuration	High-efficiency air handling
Megalam	HEPA/ULPA, depending on configuration	Cleanrooms and controlled manufacturing

Product class, dimensions, airflow and availability must be confirmed using the exact Camfil article number and current technical documentation.

3. Camfil Hi-Flo High-Efficiency Bag Filters

Camfil Hi-Flo is a range of pocket filters for general ventilation systems. Selected configurations provide high particulate filtration efficiency according to ISO 16890.

Hi-Flo filters are designed with multiple pockets to provide a large filtration surface and support effective airflow distribution.

Fresh-air systems.
Selected HEPA prefiltration systems.

For replacement applications, buyers should confirm the existing filter dimensions, number of pockets, efficiency class, airflow and pressure drop.

4. Camfil Opakfil High-Efficiency Compact Filters

Camfil Opakfil is a compact filter family designed for general ventilation applications requiring high particulate filtration efficiency within a relatively small installation depth.

Its V-Bank construction provides a large media area while supporting airflow through the filter.

Opakfil ES is one example of a product designed to combine filtration performance, low pressure drop and high dust-holding capacity.

Example: Opakfil ES

ISO 16890 Class	Dimensions	Rated Airflow	Initial Pressure Drop
ePM10 70%	592 × 592 × 296 mm	3,400 m³/h	60 Pa
ePM1 60%	592 × 592 × 296 mm	3,400 m³/h	65 Pa
ePM1 70%	592 × 592 × 296 mm	3,400 m³/h	75 Pa
ePM1 80%	592 × 592 × 296 mm	3,400 m³/h	90 Pa

These figures are manufacturer-published examples for specific configurations. They must not be applied to every Opakfil model or dimension.

5. Camfil Absolute HEPA Filters

Camfil Absolute includes high-efficiency filter configurations suitable for applications requiring greater particulate control than general ventilation filters provide.

Depending on the product family, available configurations may include EPA and HEPA efficiency classes.

Typical Applications

Industrial high-efficiency air handling.
Selected pharmaceutical applications.
Clean manufacturing facilities.
Laboratories with specified filtration requirements.
Specialized HVAC installations.

When selecting an Absolute filter, engineers must verify the exact efficiency class, dimensions, airflow, pressure drop, frame construction and sealing requirements.

6. Camfil Megalam HEPA and ULPA Filters

Camfil Megalam is a cleanroom filtration product family with selected HEPA and ULPA configurations.

Megalam products are used in controlled environments where high particulate filtration performance and installation integrity are essential.

Typical Applications

Pharmaceutical cleanrooms.
Microelectronics manufacturing.
Semiconductor production.
Selected healthcare facilities.
Critical manufacturing environments.

Exact model selection depends on the required filter class, airflow, pressure drop, frame dimensions, media type and gasket or gel-seal configuration.

Not every Megalam model is available in every HEPA or ULPA efficiency class.

7. HEPA H13 and H14 Filtration Efficiency

HEPA filters are tested and classified according to standards such as EN 1822.

Filter Class	Minimum Overall Efficiency at MPPS
H13	99.95%
H14	99.995%

MPPS stands for Most Penetrating Particle Size. Efficiency requirements at MPPS are central to the EN 1822 classification system.

HEPA filters capture airborne particles. They do not inherently remove gaseous pollutants or chemically destroy microorganisms captured on the filter media.

8. ULPA U15, U16 and U17 Filtration Efficiency

ULPA filters are used in selected applications requiring even higher particulate filtration efficiency.

Filter Class	Minimum Overall Efficiency at MPPS
U15	99.9995%
U16	99.99995%
U17	99.999995%

ULPA filters may require specialized housings, sealing arrangements and installation testing.

The use of a ULPA filter alone does not establish a cleanroom's ISO 14644 classification.

9. ISO 16890 vs. EN 1822

Standard	Primary Application	Classification Examples
ISO 16890	General ventilation particulate filters	ePM10, ePM2.5, ePM1
EN 1822	EPA, HEPA and ULPA filters	E10–E12, H13–H14, U15–U17
ISO 29463	High-efficiency filters and filter media	Classes defined by the standard

These standards serve different testing and classification purposes. Efficiency values should be compared only using an appropriate technical framework.

10. High-Efficiency Filters for Industrial AHU Systems

Industrial AHUs commonly use multistage filtration to control dust loading and protect downstream equipment.

A typical arrangement may include:

Prefilter → Fine Filter → HEPA Filter, where required.

The final configuration depends on the facility's required air quality, available fan pressure and system design.

Using a higher-efficiency filter without evaluating the AHU can reduce airflow or increase fan energy consumption.

11. High-Efficiency Filters for Pharmaceutical Manufacturing

Pharmaceutical facilities may require high-efficiency filtration in air handling systems, terminal housings and critical production environments.

Selected Camfil Absolute and Megalam configurations may be evaluated according to the applicable process and contamination-control requirements.

HEPA efficiency is only one element of a qualified cleanroom. Room airflow, pressure differentials, installation integrity, environmental monitoring and documented qualification must also be considered.

12. High-Efficiency Filters for Electronics Manufacturing

Electronics manufacturing facilities can require precise particulate control to protect sensitive components and production processes.

Depending on the manufacturing environment, HEPA or ULPA filtration may be appropriate.

Some facilities also require airborne molecular contamination control. Specialized molecular filtration must be assessed separately from particulate filtration.

13. High-Efficiency Filters for Semiconductor Cleanrooms

Semiconductor production can involve stringent requirements for airborne particles, molecular contaminants and materials compatibility.

Selected Camfil Megalam configurations can be considered for critical cleanroom filtration, subject to exact product specifications.

Filter media, outgassing characteristics, airflow, pressure drop, sealing and test documentation should be verified for the relevant manufacturing process.

14. High-Efficiency Filters for Hospitals

Healthcare facilities contain different functional areas with different ventilation and filtration requirements.

HEPA filters may be specified for selected critical areas, but not every hospital space requires HEPA filtration.

Filter selection should follow the facility's ventilation design, infection-control requirements and applicable technical guidance.

15. High-Efficiency Filters for Food Manufacturing

Food-processing facilities may require different filtration levels across production, packaging and storage areas.

Fine filters, HEPA filters and selected specialized products can be evaluated according to hygiene zoning and process requirements.

There is no universal requirement for every food-manufacturing area to use H14 or ULPA filtration.

16. Energy-Efficient High-Efficiency Filtration

High filtration efficiency must be balanced against airflow resistance and operating cost.

Important selection factors include:

Required filtration efficiency.
Initial pressure drop.
Average operating pressure drop.
Rated airflow.
Dust-holding capacity.
Expected service life.
Fan energy consumption.
Maintenance and replacement costs.

A filter with a higher initial purchase price may offer a lower total cost of ownership if its operating characteristics are more suitable for the system.

Actual energy savings depend on the fan, motor, controls, operating hours and overall system resistance.

17. How to Select Camfil High-Efficiency Air Filters

Step 1: Define the Application

Identify whether the filter is required for general ventilation, industrial HVAC, cleanroom prefiltration, terminal HEPA filtration or another specialized application.

Step 2: Determine the Required Efficiency

Specify the relevant ISO 16890, EN 1822 or ISO 29463 classification.

Step 3: Confirm Airflow

Determine the rated airflow through each filter module.

Step 4: Verify Dimensions

Confirm width, height, depth and available installation space.

Step 5: Check Pressure Drop

Evaluate the filter's initial and expected operating pressure drop against the available fan static pressure.

Step 6: Confirm Frame and Sealing

Check the holding frame, header, gasket or gel-seal interface as applicable.

Step 7: Review Documentation

Request the exact product datasheet and any required model-specific test documentation.

18. Camfil High-Efficiency Replacement Filters

VIETPHAT supports customers seeking replacement Camfil filters for existing air handling units and cleanroom systems.

To reduce the risk of ordering an incompatible filter, customers should provide:

Existing product name.
Article number or product code.
Width × Height × Depth.
Required efficiency class.
Rated airflow.
Initial pressure drop.

Matching dimensions alone does not establish technical equivalence.

19. Maintenance and Replacement

High-efficiency filters should be maintained according to their application and manufacturer instructions.

For general ventilation filters, pressure-drop monitoring can help determine when replacement is required.

For HEPA and ULPA installations, maintenance may also involve physical inspection, airflow verification and integrity testing where applicable.

Conventional HEPA and ULPA filters should not be washed unless explicitly permitted by the exact product manufacturer.
