Description
This filter media uses a PP+PET melt-blown as the core filtration layer, providing high dust holding capacity—approximately 15g/㎡ higher than conventional media, lower initial pressure drop, and long-lasting efficiency, reducing replacement costs.

Product Advantages
1. PP + PET Melt-Blown Filtration Structure
The three-layer synthetic structure combines PP and PET melt-blown materials to create a stable filtration layer with effective particle capture and consistent airflow performance.
2. Higher Dust Holding Capacity
Compared with conventional pocket filter media, the melt-blown structure provides approximately 15 g/㎡ higher dust holding capacity, helping maintain filtration performance for longer operating periods.
3. Low Initial Pressure Drop
The optimized fiber structure allows air to pass through the media with relatively low resistance. This helps reduce the energy demand of ventilation systems and supports more efficient HVAC operation.
4. Reinforced Structure for Stable Airflow
The thickened air-outlet fabric provides additional protection against deformation under high airflow. Reinforced spacers help maintain pocket geometry, distribute airflow evenly, and reduce the risk of pocket collapse.
5. Multiple Efficiency Grades
Available from G4 to F9, the media can be selected according to different filtration requirements, making it suitable for both general ventilation and higher-efficiency air filtration systems.
6. Consistent Media Performance
The controlled basis weight, thickness, layer structure, pressure drop, and filtration efficiency provide manufacturers with stable raw material performance for producing pocket-type air filters.
7. Suitable for Filter Manufacturing
The media is designed specifically for pocket filter production, making it a practical material choice for HVAC filter manufacturers, distributors, and air filtration solution providers.
Application Areas
Commercial & Building HVAC
Suitable for air handling and ventilation systems in office buildings, shopping centers, hotels, and other commercial facilities where reliable particle filtration and energy-efficient airflow are required.
Industrial Ventilation
Designed for factories and industrial facilities that need continuous removal of airborne dust and particulate matter from incoming or circulating air.
Hospitals & Healthcare Facilities
Can be used as a pre-filtration or intermediate filtration stage in ventilation systems where controlled indoor air quality is important.
Cleanroom Pre-Filtration
Suitable for upstream filtration in cleanroom air-handling systems, helping reduce the particulate load reaching higher-efficiency filtration stages.
Pharmaceutical & Food Production
Applicable to controlled production environments where stable air filtration is required to support cleaner manufacturing conditions.
HVAC Filter Manufacturing
An ideal media option for manufacturers producing pocket filters for commercial, industrial, institutional, and other air-handling applications.
