The air purifier filter is the core filter component in the air purification equipment. It mainly uses different levels of filter materials to classify particles in the air.
Depending on the structure and usage scenarios of the air purification equipment, you can configure:
Primary efficiency filtration → Medium efficiency filtration → HEPA high efficiency filtration → ULPA ultra high efficiency filtration
Different filtration levels undertake different air treatment tasks.
Primary-efficiency filters are mainly used for pre-filtration of larger particles, medium-efficiency filters further process finer particles, HEPA filters are used to control fine particles in clean air, and ULPA filters are used in environments with higher requirements for air cleanliness.

Actual products can use single-stage filtration according to the air volume and spatial structure of the equipment, or can use a combination of multi-stage filtration.
HEPA filter is a common high-efficiency filtration component in air purifiers. It is mainly used to filter small particles in the air.
Aili Industrial can provide HEPA filters of different sizes and thicknesses according to the internal structure of the air purifier.
Common filtering levels include:
H13 → H14 → U15 → U16 → U17
Different levels of filters are suitable for air treatment scenarios with different cleanliness requirements.
For ordinary air purification equipment, the appropriate filtration level can be selected based on the equipment's air volume, fan capacity and filter installation space; for clean rooms, semiconductors and precision manufacturing environments, the selection needs to be based on actual cleanliness requirements.
ULPA filters are mainly used in environments with high requirements for air cleanliness.
Compared with ordinary air purifier filters, ULPA filters usually need to more strictly match the equipment air volume, filter area and system resistance.
Common applications include:
Semiconductor clean room → Precision electronics → Optoelectronics manufacturing → Laboratory → High cleanliness air treatment equipment
Aili Industrial can customize ULPA filters according to equipment size, air volume and installation space.
The primary filter is mainly used for front-end filtration of air purification equipment.
Its function is to first treat larger particles in the air and reduce the particle load of the rear-end medium-efficiency, HEPA or ULPA filter.
Common materials include:
Synthetic fiber → Non-woven filter material → Metal mesh → Cleanable filter material
The primary filter can be made into flat, foldable and other structures according to the structure of the air purifier.
When the medium-efficiency filter is located between the primary-efficiency filter and the HEPA filter, it can assume the intermediate filtration role.
Common applications:
Hospital→Laboratory→Commercial building→Industrial plant→Clean room→Air purification equipment
Medium-efficiency filters can be made of synthetic fiber, PP materials and other suitable filter materials, and can be customized according to the size of the equipment.
Air purifier filters can use different frames and filter materials depending on the structure of the device.

Different brands and models of air purifiers have different internal spaces, air volumes, and filter installation methods, so the filter sizes are not completely uniform.
Aili Industry supports customizing air purifier filters based on equipment parameters.
Equipment model → Original filter size → Air volume → Installation space → Filtration level → Filter material → Frame → Sealing method
Customers can provide:
Length→ Width→ Thickness→ Equipment air volume→ Fan parameters→ Filtration level→ Installation method→ Usage environment
Based on these parameters, the filter structure and filter material configuration can be made.
Air purifier filters can be customized to suit the size of the device.
Common size expressions:
Length × Width × Thickness
For example:
300×300×20mm → 400×300×20mm → 400×400×50mm → 500×400×50mm
For industrial air purification equipment, larger HEPA, ULPA or V-type filters can also be used.
The actual size can be designed according to the internal installation space of the device.
The air purifier filter cannot only be selected based on the filtration level, but also needs to be selected based on the equipment's air volume and fan capacity.
Selection can be carried out according to the following steps:
Determine the type of equipment → Determine the air treatment volume → Determine the filter size → Determine the type of pollutants → Determine the filtration level → Determine the filter material → Calculate the air resistance → Determine the replacement cycle
If you are replacing the original filter, you can directly provide:
Equipment brand → Equipment model → Original filter photo → Original filter size → Original filter filtration level
Aili Industrial can match the size and material to the existing filter structure.
Air purifier filters are a product category, and HEPA filters are one of the high-efficiency filtration types.
Simple understanding:
Air Purifier Filter → Product Category
Primary filter → pre-filtration
Medium efficiency filter → intermediate filtration
HEPA filter → high efficiency particulate matter filtration
ULPA filter → ultra-low penetration air filtration
An air purification equipment can use one or more filter combinations depending on the actual design.

Home air purifiers usually need to consider dust, pollen, fine particles, etc. in the air.
Common structures:
Primary filter → HEPA filter → Activated carbon filter
The primary filter is responsible for pre-filtration of front-end particles, the HEPA filter is used to filter fine particles, and the activated carbon material is used to absorb some gaseous pollutants and odors in the air.
If the device has a composite filtration structure, multiple filtration functions can be combined in one filter element according to the internal space of the device.
Commercial air purification equipment usually has a larger processing air volume, so the filter area, filter resistance and replacement cycle need to be considered comprehensively.
Common applications:
Office → Shopping mall → Hotel → School → Medical institution → Public building
For equipment with large air volume, a larger filter area or V-shaped structure filter can be used to match the internal space and air treatment needs of the equipment.
Industrial air purification equipment requires filter configurations based on the types of pollutants in the production environment.
Common contaminants include:
Dust → fiber → smoke → fine particulate matter → process particulate matter
For different pollutants, you can use:
Primary efficiency filtration → Medium efficiency filtration → HEPA filtration → ULPA filtration
If VOCs, acidic gases, or other molecular pollutants are present in the air, chemical filters can also be added in addition to the particulate matter filtration system.
For special air treatment environments such as semiconductors, electronics, and laboratories, only treating particulate matter may not necessarily cover all air quality control needs.
Can be configured according to actual pollutants:
Primary efficiency filtration → Medium efficiency filtration → HEPA/ULPA → Chemical filtration
in:
HEPA/ULPA → Particulate matter control
Chemical filter → Control of molecular pollutants such as AMC, VOC, acid gas, alkaline gas, etc.

Can. HEPA filter is a high-efficiency particulate filter component commonly used in air purification equipment. The specific grade needs to be selected based on the air volume of the equipment, fan capacity and usage environment.
Can. Aili Industry supports customization based on equipment model, filter size, thickness, air volume, filtration level and installation method.
Common types include primary-efficiency filters, medium-efficiency filters, HEPA filters and ULPA filters. Activated carbon or chemical filter materials can also be added according to pollutants.
Both are high-efficiency particulate matter filters, but their filtration levels and applicable scenarios are different. HEPA is commonly used in air purifiers, hospitals and clean rooms, while ULPA is more commonly used in semiconductors, precision electronics and other environments that have higher requirements for air cleanliness.
The replacement cycle is related to air quality, equipment running time, air volume and filter dust holding capacity. In actual use, maintenance can be carried out based on the equipment running time, filter pressure difference or equipment prompts.
