In clean room, HVAC and industrial air treatment projects, if the system needs to handle a larger volume of air, the effective filtration area, structure, face velocity and resistance of the filter will all affect product selection.
The high-efficiency filter with partitions uses partitions to support the pleated filter material to maintain a certain distance between adjacent filter pleats and form a filter channel for air to pass through.
Therefore, when designing a large air volume filtration system, the configuration can be made accordingly according to the filter size, filter material area and system operating conditions.
Things to note are:
Having a baffle structure does not mean that the filter is suitable for all large air volume systems.
The final air volume still needs to be determined based on the specific model and test parameters.
After the air enters the filter, the particles are intercepted by the filter material.
Its basic process can be understood as:
Air enters → passes through the filter material → particles are filtered → clean air is output
The function of the partition structure is to maintain a stable spacing between the pleated filter materials.
The structure can be expressed as:
Filter media → folded → separated by partitions → formed filter channels → air passes through
The partition is not directly responsible for filtration, but mainly plays the role of supporting the filter material and maintaining the distance between the filter pleats .
The filter needs to allow a certain amount of air to pass through the filter material.
Under other similar conditions, the filter area is related to the surface wind speed of air passing through the filter material.
It can be simply understood as:
The filtration area increases → the air volume passing through the unit area can be reduced → which is beneficial to the air volume configuration of the system
But this does not mean that simply increasing the filter area can increase the air volume infinitely.
Actual air volume is also affected by:
filter area |
face wind speed |
Filtration efficiency |
system resistance |
|---|---|---|---|
Filter material expansion area |
The speed of air passing through the filter surface |
H13/H14 etc. |
Pa |
filter size |
Filter material structure |
System air volume |
Fan capacity |
W×H×D |
There are partitions etc. |
m³/h |
Determine according to the system |
Therefore, these parameters need to be considered together when selecting a high air volume filter.
It can be used in corresponding large air volume air filtration systems, but the specific air volume needs to be determined according to the product model.
The high-efficiency filter with partitions uses partitions to maintain the pleat distance of the filter material, and can be configured with a larger expansion area of the filter material within a certain size range.
For projects with large air treatment capacity, the following can be used:
System air volume → filter size → filter material area → surface air velocity → resistance
Perform product matching.
If the project requires high air volume, structures such as V-type high-efficiency filters can be further considered .
When purchasing a large air volume high-efficiency filter, it is not recommended to only ask:
'Can this filter be used for large air volume?'
A more accurate way is to provide the specific parameters of the system.
System air volume |
Filtration efficiency |
filter size |
initial resistance |
|---|---|---|---|
m³/h |
H13/H14 etc. |
W×H×D |
Pa |
face wind speed |
Filter area |
Usage environment |
Fan conditions |
m/s |
Determine based on structure |
Clean room/HVAC, etc. |
Determine according to the system |
Together, these parameters determine whether a filter is suitable for your current air handling system.
For example, just because two filters have the same dimensions doesn't mean they have the same airflow rating.
Because the filter also involves:
Filter material type → filter pleat structure → effective filtration area → filtration efficiency → surface wind speed → resistance
If one of these parameters changes, the air volume and resistance performance of the product may also differ.
Therefore, engineering projects should be based on the technical parameters and test data of specific models .
If the project requires a larger air handling capacity, you can compare the partitioned structure with the V-shaped structure.
High efficiency filter with partition |
V type high efficiency filter |
|---|---|
Use partitions to support filter media |
Multiple sets of filter elements form a V-shaped structure |
Traditional partitioned structure |
Suitable for increasing filter media expansion area |
Can be used with a variety of air filtration systems |
Commonly used for air treatment with larger air volume |
Determine air volume based on size and product configuration |
Determine air volume based on V-shaped structure and product parameters |
There is no simple substitution relationship between the two products.
If the equipment adopts a traditional high-efficiency filter installation structure, partition products can be considered; if the system space and air volume conditions are suitable for a V-shaped structure, you can further select a V-shaped filter.
You cannot decide whether to choose H13 or H14 simply based on 'large air volume'.
H13 and H14 belong to different filtration efficiency levels, and the specific selection should be determined based on the project's cleanliness requirements, system design and relevant standards .
For example:
Project requirements |
Selection considerations |
|---|---|
Common high-efficiency filtration requirements |
Choose the appropriate grade according to the design |
Higher cleanliness requirements |
Confirm efficiency levels such as H13/H14 |
High cleanliness applications such as semiconductors |
Choose according to cleanliness level and equipment requirements |
Special cleaning requirements |
Further evaluation of ULPA if necessary |
Also need to consider:
Filtration efficiency increases → System resistance may change → Fan margin needs to be rechecked
Therefore, we cannot just look at filtration efficiency as a parameter.
Can.
Baffled high-efficiency filters can be used in HVAC air handling systems based on system design requirements.
In HVAC applications, there are often important considerations:
System air volume → filter size → filtration efficiency → initial resistance → fan margin
For equipment such as air conditioning boxes and air handling units that require large air handling capacity, high-efficiency filters with different structures can also be considered based on the internal space and air volume requirements of the equipment.
For example:
HVAC applications |
Key parameters |
|---|---|
air conditioning box |
Air volume, filtration efficiency, resistance |
air handling unit |
Filter size, air volume |
Clean air conditioning system |
Filtration efficiency and cleanliness requirements |
Industrial air treatment |
Air volume, environmental conditions, filter structure |
Can.
Clean room air filtration systems usually need to select corresponding filtration efficiency and filter structure according to the cleanliness level.
High-efficiency filters with partitions can be used in some clean room air filtration systems. The specific application location needs to be determined according to the clean room design.
For example:
Fresh air treatment → Air conditioning box filtration → Clean air conditioning → Terminal high efficiency filtration
Filtering requirements are not exactly the same across locations.
Therefore, clean room projects should configure filters based on the overall air handling system, rather than just selecting a certain device.
In addition to high-efficiency filter products, Aili Industry also involves FFU, EFU and clean air treatment products.。
Therefore, when selecting a project, the parameters of the actual equipment and air treatment system can be combined for matching.
For example, the customer needs:
High air volume HVAC filter
Can provide:
System air volume + filtration efficiency + installation size + initial resistance requirements
If the customer needs:
FFU/EFU matching high efficiency filter
You can further provide:
Equipment model + filter size + target air volume/wind speed + filtration efficiency + equipment installation space
This allows filter specifications to be determined based on actual equipment conditions.
Aili Industrial can configure corresponding high-efficiency and ultra-high-efficiency filtration products according to different application scenarios.

For different projects, the structure, efficiency and size of the filter need to be confirmed based on actual parameters.
Aili Industrial's product system also covers FFU, EFU, fans and control systems . In equipment matching projects, the parameters of filters and air purification equipment can be matched together.
If you are planning to purchase a high-efficiency filter with large air volume with partitions, it is recommended to provide the following information at one time:
01 Installation dimensions |
02 System air volume |
03 Filtration efficiency |
04 Initial resistance |
|---|---|---|---|
Length×width×height |
m³/h |
H13/H14 etc. |
Pa |
05 Usage environment |
06 Equipment Type |
07 Operating temperature |
08 quantity |
Clean room/HVAC, etc. |
Air conditioning boxes/equipment, etc. |
℃ |
Taiwan/unit |
If it is a replacement project, you can provide it directly:
Original filter photo + size + model + device used
Aili Industrial can further confirm product specifications based on this basic information.
The actual project can be carried out according to the following process:
Confirm system air volume → Confirm filtration efficiency → Confirm installation space → Confirm filter structure → Check resistance → Confirm product specifications
If system space is limited, filter thickness will also need to be focused on.
If the system air volume is large, you need to focus on the filter area, face velocity and resistance.
If the cleanliness requirements are higher, the HEPA or ULPA grade needs to be further confirmed.
High-efficiency filters are not products that can be selected simply by looking at one parameter.
For clean room, HVAC, electronic manufacturing, pharmaceutical, FFU, EFU and other projects, you need to:
Filtration efficiency + air volume + resistance + size + structure + usage environment
judge together.
Aili Industrial can high-efficiency filters with partitions, high-efficiency filters without partitions, V-type high-efficiency filters, and ULPA ultra-high-efficiency filters .configure the product types according to the project parameters provided by the customer, including
If the project involves both FFU or EFU, the equipment size, fan parameters and filter specifications can also be combined for matching confirmation.

uncertain. Suitability needs to be confirmed based on system air volume, filter size, filtration area, face wind speed, resistance and fan conditions.
no. The filter needs to match the system air volume, filtration efficiency and resistance. The actual air volume should be based on the specific product parameters.
uncertain. The V-shaped structure is a product form suitable for corresponding air treatment conditions, and ultimately needs to be selected based on equipment space, air volume and system design.
You can't judge like this. H13 and H14 are different filtration efficiency levels, and large air volume is not the only basis for selecting filtration efficiency.
