China F7 M7 Bag Filter - High-Quality Suppliers from Leading Factory for Efficient Air Filtration Solutions
What is Synthetic Pocket Filter?
The filter material is made of high-performance non-woven fabric by the thermal melting process, to avoid the discomfort caused to the human body by old-fashioned glass fiber materials. The filter material contains electrostatic fiber, which has an excellent filtering effect on sub-micron dust.
Features
- Extra long service life
- High burst resistance
- Large surface area
- Fits all commonly used filter frames
- High efficiencies at low pressure drops
- Uniform identification is used for appearance color, which is easy to identify.
Application
The pocket filter is suitable for intermediate filtration in an air conditioning system. It is located in front of the HEPA filter.
It is mainly used to filter 1-5 megabytes of dust particles to protect the lower filters in the system and the system itself. It has the advantages of small resistance and a large volume of air. Optional style has bag type, frame type, and combination type.

How often should bag filters be replaced?
Replacement Cycle:
- Under the rated air volume, it needs to be replaced in 3 - 6 months.
- Resistance of 450Pa or more must be replaced.
- If it is washable filter material, it can be washed with clean water or neutral detergent solution to dry and then used, washed up to two times, and then replaced.
- The dust concentration in the environment is large, and the service life will be shortened.
Frequently Asked Questions (FAQ)
What is a Synthetic Pocket Filter used for?
It is primarily used for intermediate filtration in air conditioning systems. Placed in front of HEPA filters, it effectively captures 1-5 sub-micron dust particles to protect lower filters and the overall system.
What are the advantages of synthetic filter media over glass fiber?
Synthetic filter media is made of high-performance non-woven fabric via a thermal melting process. Unlike old-fashioned glass fiber, it avoids causing physical discomfort to humans and contains electrostatic fibers that offer an excellent filtering effect on sub-micron dust.
How long does a synthetic bag filter last?
Under standard rated air volume, the filter typically needs to be replaced every 3 to 6 months. However, if used in environments with high dust concentrations, its service life will be shortened.
Can I wash and reuse the pocket filter?
If the filter is made of specific washable materials, it can be gently washed with clean water or a neutral detergent solution, allowed to dry completely, and reused. It can generally be washed up to two times before requiring a full replacement.
When must the bag filter be replaced immediately?
Regardless of the time in service, the filter must be replaced immediately if the system's air resistance reaches 450Pa or more, as it indicates the filter is fully saturated with dust.
What are the key features of this filter design?
Key features include an extra-long service life, high burst resistance, a large surface area for efficient airflow, high efficiency at low pressure drops, and compatibility with all commonly used filter frames.
