What is the difference between high-efficiency filters with and without partitions?

When purchasing HEPA high-efficiency filters, in addition to H13, H14 and other filtration efficiency levels, customers often encounter a problem:

'What is the difference between high-efficiency filters with partitions and without partitions?'

The main difference between these two products is not the filtration efficiency level, but the support and pleat structure of the filter material.。

Simple understanding:

High-efficiency filter with partitions: partitions are set between filter materials to maintain the distance between filter pleats.

Partitionless high-efficiency filter: It does not use traditional partitions and maintains the pleat distance of the filter material through other structural methods.

Both structures can be used for high-efficiency air filtration, but the specific applicable scenarios, product size, filtration area, and installation methods may be different.

1. What is a high-efficiency filter with partitions?

The high-efficiency filter with partitions sets partitions between pleated filter materials to keep a certain distance between the filter material pleats.

The basic structure can be understood as:

Filter media → folding → partition separation → sealing → outer frame

The main functions of partitions are:

• Maintain filter media pleat distance

• Support filter material structure

• Create channels for air to pass through

• Keep the internal structure of the filter stable

Common partition materials include paper partitions and aluminum partitions. Which one to use needs to be determined based on the product structure and project requirements.

2. What is a high-efficiency filter without partitions?

The partitionless high-efficiency filter does not use traditional paper partitions or aluminum partitions, but maintains the filter pleat spacing through the folding structure of the filter material and other fixing methods.

Common structures can be understood as:

Filter media → folding → fixed intervals → sealing → outer frame

Since there are no traditional partitions, its internal structure and filter material expansion method are different from products with partitions.

The partition-less structure is more common in FFU, EFU and some clean equipment with limited space.

3. What is the biggest difference between having partitions and without partitions?

It can be understood from the following aspects:

Special attention is required:

We cannot simply think that no partitions are necessarily better than having partitions, nor can we think that having partitions is necessarily better than no partitions.

The two structures correspond to different product design and application requirements.

4. Is the filtration efficiency the same with or without partitions?

The same filtration efficiency class can be used.

For example, depending on the specific product design, there can be:

H13 high efficiency filter with partition

Can also exist:

H14 high efficiency filter with partition

At the same time, it can also be configured according to the product structure:

H13 high efficiency filter without partition

or:

H14 high efficiency filter without partition

therefore:

'With partitions/without partitions' describes the structure, while 'H13/H14' describes the filtration efficiency level.

These two parameters cannot be confused.

5. Which filtration efficiency is higher, with or without partitions?

This cannot be judged directly.

The efficiency of the filter is related to factors such as filter material, filter structure, manufacturing process and testing conditions.

If two products reach the same filtration efficiency level, their level requirements are judged according to the corresponding standards.

therefore:

With partitions≠ higher filtration efficiency

No partitions ≠ higher filtration efficiency

What really needs to be compared is the filtration efficiency testing data and technical parameters of specific products.。

6. Which one has greater air volume, with or without partitions?

Likewise, one cannot judge solely based on whether there are partitions.

Filter air volume is related to:

Filtration area + face velocity + filter material structure + size + initial resistance

related.

For example:

If customers need to compare the air volume of two products, they should check the product parameters under the same or comparable test conditions.

7. Why do FFU often use high-efficiency filters without partitions?

FFU is an air purification device that combines a fan and a high-efficiency filter.

Its internal space usually needs to accommodate both:

Fan + filter + control components + box structure

Therefore, the structure, thickness and installation method of the filter need to match the FFU box.

High-efficiency filters without partitions can be designed accordingly according to the FFU structure, so they are common in some FFU products.

However, the specific filter structure used by FFU should still be based on the equipment design and product parameters.

8. Why do EFUs often use partition-less structures?

EFU is usually installed on production equipment or clean equipment.

Compared with ordinary clean room filters, EFU may be affected by:

Equipment height + installation space + air volume + filtration efficiency

and other conditions.

Especially when space at the top of the equipment is limited, filter thickness can become an important design parameter.

Aili Industrial's EFU products include equipment configurations using high-efficiency filters, and provide corresponding filter specifications based on the product structure.

Therefore, when selecting EFU, you cannot just ask:

'Do you want H14 or H13?'

You should also confirm:

Filter size + thickness + air volume + resistance + equipment installation space

9. What applications are suitable for high-efficiency filters with partitions?

Baffled high-efficiency filters can be used in a variety of air filtration systems based on specific product configurations.

For example:

Actual products need to be selected based on air volume, efficiency, size and equipment structure.

10. What applications are suitable for high-efficiency filters without partitions?

The partition-less structure is often used in equipment that requires filter structure and installation space.

For example:

Especially for FFU, EFU and other equipment, the filter needs to be matched with the equipment as a whole.

11. What is the difference between the filter area with partitions and without partitions?

Filtration area is an important parameter in the design of high-efficiency filters.

After the filter material is folded, it can form a larger expansion area in a limited outer size.

However, due to the different internal structures between those with partitions and those without partitions, the folding method of the filter material, the number of filter pleats and the effective filtration area may be different.

Therefore, it cannot only be based on:

'Filter sizes are the same'

Just think:

'The filter area must be the same.'

If your project requires comparing filter performance, you should directly check the product parameters provided by the manufacturer.

12. How to choose between high-efficiency filters with partitions and without partitions?

This can be done according to the following logic:

First determine the equipment to be used → then determine the installation space → then determine the filtration efficiency → then determine the air volume and resistance → finally confirm the filter structure

For example:

This is more suitable for actual projects than simply asking 'with partitions or without partitions'.

13. How should we understand H13/H14 and partitions/no partitions?

This is where many buyers are easily confused.

This can be distinguished using a simple table:

so:

H13/H14 is a dimension.

With/without partitions is another dimension.

It needs to be determined at the same time when selecting the product.

14. What high-efficiency filter structures does Aili Industry have?

Aili Industrial's high-efficiency and ultra-high-efficiency filtration products can cover different structures according to project requirements.

At the same time, Aili Industry also produces FFU, EFU and related clean air treatment equipment。

Therefore, if the customer needs:

'Filter+FFU'

or:

'Filter+EFU'

You can directly confirm the matching according to the equipment parameters.

15. How does Aili Industry help customers choose filter structures?

If the customer is not sure whether to choose with or without partitions, they can first provide:

If the filter is to be replaced on an old device, we can directly provide:

Original filter photo + product size + model number + device photo

In this way, the original structure can be confirmed first, and then the product can be matched according to the actual parameters.

16. Product Selection of Aili Industrial High-Efficiency Filters

For different projects, Aili Industrial can select the corresponding filter structure according to actual application conditions.

For example:

Clean room project

→ Determine the filtration efficiency according to the cleanliness requirements
→ Determine the filter specifications according to the installation size
→ Confirm the product parameters according to the system air volume

FFU project

→ Determine the filter size according to the FFU model
→ Match the filter resistance according to the fan parameters
→ Determine the H13/H14 grade according to the cleanliness requirements

EFU project

→ Confirm the filter thickness according to the equipment space
→ Confirm the filter specifications according to the working air volume
→ Select the corresponding filtration efficiency according to the cleanliness requirements

This selection method allows the filter parameters to correspond to actual equipment conditions.

17. When choosing a high-efficiency filter, don't just look at 'with or without partitions'

When actually purchasing, it is recommended to confirm the following parameters at one time:

Filtration efficiency + size + air volume + initial resistance + structure + usage environment

If it involves equipment matching, you need to add:

Equipment model + installation space + fan parameters

Aili Industrial can help identify suitable high-efficiency filter products based on this information.

18. Frequently Asked Questions

Which is better, a high-efficiency filter with partitions or a high-efficiency filter without partitions?

It cannot be simply compared. The two products have different structures and should be selected based on equipment, installation space, air volume, resistance and filtration efficiency requirements.

Are filters without partitions necessarily thinner than filters with partitions?

uncertain. The thickness of the product is related to the specific structure, filter material and design. You need to check the specific model parameters.

Is the filtration efficiency of the H14 filter without partitions the same as that of the H14 filter with partitions?

If two products reach the same H14 level, their corresponding filtration efficiency level requirements are the same, but the test data for specific products should still be checked.

Does FFU always use a filter without partitions?

uncertain. The specific filter structure used depends on the design and product configuration of the FFU.

Should a clean room have partitions or no partitions?

It needs to be determined based on the filter installation location, size, air volume, efficiency and system design of the clean room. It cannot be judged just based on the name of the clean room.

Are there partition filters that can be used with FFU?

It can be configured according to the FFU structure, but whether it is suitable requires confirming the FFU box size, filter size, air volume and fan parameters.

19. Conclusion of the article

There are two different filter structures with and without partitions.

The core difference between high-efficiency filters with partitions and without partitions lies in the maintenance of the pleat distance of the filter media and the different internal structures.。

The choice should not be based on a simple comparison of which structure is better, but should be determined based on the actual application.

The core selection logic can be summarized as:

Equipment used → Installation space → Filtration efficiency → Air volume → Resistance → Filter structure

For clean rooms and HVAC systems, corresponding high-efficiency filters with or without partitions can be selected according to the system design; for equipment such as FFU and EFU, further consideration needs to be given to filter thickness, installation size, and fan parameters.
