Paper frame primary filters serve as the first stage in air filtration systems, removing larger particles (such as dust, hair, fibers, etc.) to protect downstream filters and equipment. They have extensive applications wherever basic air purification is required, including:
HVAC (Heating, Ventilation and Air Conditioning) system
It is one of the most important application fields of paper frame primary filters, suitable for central air conditioning and ventilation systems in buildings such as office buildings, shopping malls, hotels, hospitals, and residences.
They remove large particles from incoming air to prevent buildup on system components like heat exchangers and fans.
2. Industrial production workshops
Many industrial production environments (such as electronic assembly, mechanical processing, food processing, textile workshops, etc.) require basic air purification to reduce the impact of dust in the air on product quality or production equipment.
The paper frame primary filter can be used as a pre-filtering device, installed at the ventilation air intake of the workshop or in local purification equipment, to initially filter large particle pollutants in the outside air or the circulating air within the workshop.
3. Pre-filtration for cleanrooms and laboratories
In cleanrooms with high requirements for air cleanliness (such as pharmaceutical cleanrooms and semiconductor cleanrooms) or precision laboratories, air filtration systems typically adopt a multi-stage filtration combination of “primary efficiency + medium efficiency + high efficiency”.
As the first stage of filtration, the paper frame primary filter undertakes the main task of filtering large particles, reducing the burden on medium and high-efficiency filters, extending their replacement cycle and lowering the overall filtration cost.
4. Ventilation systems in public places
In crowded public places such as airports, railway stations, stadiums and cinemas, the ventilation system needs to continuously introduce fresh air and filter out impurities in it (such as dust, pollen, insects, etc.).
Paper frame primary filters, due to their low cost and easy replacement, are suitable for ventilation air intake filtration in such places, ensuring that the air sent into the room is basically clean.
5. Equipment cooling air filtration
Some industrial equipment (such as generators, cooling towers, large motors, etc.) needs to be cooled by drawing in air through fans during operation. If the air contains a large amount of dust, it may lead to dust accumulation inside the equipment, poor heat dissipation, and even cause malfunctions.
The paper frame primary filter can be installed at the air inlet of the equipment to filter out large particle impurities in the cooling air and protect the normal operation of the equipment.

The core advantages of paper frame primary filters are low cost, moderate dust holding capacity and easy replacement. However, their filtration accuracy is relatively low (usually G1-G4 grades, in accordance with EN 779 standard), so they are mainly used for primary filtration or as a pre-protection for high-grade filtration systems. They are suitable for scenarios with low requirements for air cleanliness or the first stage of multi-stage filtration systems.
