A high-efficiency filter with partitions, also known as a HEPA filter with partitions , is a high-efficiency air filter that uses partitions to separate and support pleats of filter material.
Its basic structure usually outer frame, filter media, partitions, sealing materials and sealing gaskets . consists of After the filter material is folded, partitions are set between adjacent filter pleats to keep the filter material in a stable filter channel and unfolded state.
Commonly seen in the industry are high-efficiency filters with partitions. The filter material is usually made of ultra-fine glass fiber material. The partitions can be made of paper or aluminum according to the product configuration, and the outer frame can be made of corresponding materials according to the use environment. In the public product information, you can also see that H13 and H14 have partitioned high-efficiency filters, as well as different frame configurations such as galvanized, aluminum profiles, and stainless steel.
For systems that require higher air cleanliness, high-efficiency filters with partitions are usually used as high-efficiency terminal filtration links in air treatment systems.
The core feature of the partitioned high-efficiency filter is that there are rigid partitions between the filter media.。
Simply put, it can be understood as:
Filter media → fold → separated by partitions → form a stable air flow channel → form a high-efficiency filter
The function of the partition is to maintain the pleat distance of the filter material so that the filter material maintains a relatively stable structure during operation.
Unlike high-efficiency filters without partitions that use glue lines or hot melt glue to separate filter pleats, filters with partitions use physical partitions to form the spacing between filter materials. Therefore, they have their own product features in terms of product structure, filter material area, size, and air volume configuration.

The materials and structural configurations of different manufacturers will be different, so the actual product should be subject to the technical parameters of the specific model. Public product information shows that the common filter material for high-efficiency filters with partitions is glass fiber, and the partitions can be made of paper or aluminum.
High-efficiency filters with partitions are mainly used in air treatment systems that have high requirements for air cleanliness.

The public product information will also include partitioned high-efficiency filters used in final-stage filtration of clean room ventilation and air-conditioning systems, electronics, optics, semiconductors, biopharmaceuticals, hospitals, food and other scenarios.
It should be noted that the specific filtration efficiency, size and structure to be used is not only determined by the industry name , but also needs to be selected based on the cleanliness level, system air volume, installation space and equipment design requirements.
High-efficiency filters with partitions can be configured with corresponding filtration efficiency levels according to different cleaning requirements.
For clean room and high-efficiency air filtration applications, common products on the market include H13 and H14。

Specific efficiency is determined according to product testing standards |
In the public product information, you can see that H13 and H14 high-efficiency filter products with partitions have been tested for filtration efficiency in accordance with corresponding standards.
Therefore, when purchasing, you should not just look at the model mark 'H13' or 'H14'. You should also confirm the test standards, test methods and specific product testing data used.。
This is a common problem faced by customers during the actual selection process.
Both can be used for high-efficiency air filtration, but the main difference lies in the separation method and internal structure of the filter material。

Industry product information also lists HEPA filter products with partitions and without partitions as two different structures.
Therefore, it cannot be simply understood as which one is better . The actual selection needs to be comprehensively determined based on equipment size, air volume, resistance, filtration efficiency and installation space.
Yes, but the specific air volume needs the filter size, filter material area, filtration efficiency, face air velocity and system resistance .to be determined based on
The partition structure maintains the distance between filter materials through partitions to form a stable air flow channel. Products of different sizes and depths can correspond to different air volume and resistance configurations.
For example, in the public product parameters, the 610×610mm partitioned H13/H14 filter can correspond to different air volume and resistance configurations.
Therefore, if the project requires a large air treatment capacity, the suitability cannot be judged only by the filter size, but should:
System air volume → Filtration efficiency → Filter size → Initial resistance → Fan margin
Confirm together.
Can. The size of filters in actual clean projects is not completely uniform, so Aili Industrial's partitioned high-efficiency filters can be adjusted in size and configuration according to project requirements.

The most important of these are the first three:
Installation dimensions |
System air volume |
Filtration efficiency |
Usage environment |
|---|---|---|---|

For projects with high cleanliness requirements such as semiconductors and flat panel displays, it is necessary to further determine whether to use H13, H14 or ULPA ultra-high efficiency filters based on the specific cleanliness level and equipment form , rather than simply choosing based on the industry name.
For purchasers, HVAC designers or clean room engineers, you can choose according to the following logic:
Determine the cleanliness requirements → Determine the filtration efficiency → Determine the system air volume → Determine the installation size → Confirm the resistance requirements → Confirm the filter configuration
This can avoid directly replacing filters based on 'same size'.
If it is a clean room renovation or filter replacement project, it is recommended to check the original filter size, air volume, filtration efficiency and installation frame at the same time to ensure that the new filter matches the original system.
The partitioned high-efficiency filter maintains the distance between the filter pleats through partitions to form a stable filtration structure. It can provide H13, H14 and other filtration efficiency configurations according to different projects, and is widely used in clean rooms, HVAC, electronic manufacturing, pharmaceuticals, hospitals and other air purification systems.
When choosing a high-efficiency filter with partitions, you should not only focus on filtration efficiency, but also need to consider comprehensively:
Filtration efficiency + air volume + resistance + size + filter material + frame + usage environment
