Quality F7 M7 Bag Filter from China Suppliers and Factory - Reliable 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?
- 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
What is the main advantage of synthetic pocket filters over glass fiber?
Synthetic pocket filters are made of high-performance non-woven fabric via a thermal melting process. This avoids the physical discomfort and shedding issues often associated with old-fashioned glass fiber materials, while still providing an excellent filtering effect on sub-micron dust.
Where are pocket filters typically installed in an HVAC system?
They are suitable for intermediate filtration in an air conditioning system and are usually located directly in front of the HEPA filter to protect the lower filters and the system itself.
Can I wash and reuse synthetic bag filters?
Yes, if the filter utilizes washable filter material, it can be washed with clean water or a neutral detergent solution, allowed to dry completely, and reused. However, it is recommended to wash them up to a maximum of two times before full replacement.
How do I know when it's time to replace the filter?
Filters should be replaced every 3 to 6 months under rated air volume conditions. Additionally, if the system resistance reaches 450Pa or more, immediate replacement is required to maintain system efficiency.
Are the frame sizes customizable?
Yes, our synthetic pocket filters are designed to fit all commonly used filter frames (Aluminum, Galvanized, or Plastic). Other specifications and dimensions can also be customized according to your specific requirements.
What happens if the dust concentration in the environment is very high?
In environments with high dust concentration, the filter will reach its maximum holding capacity faster, which means the overall service life will be shortened and more frequent replacements will be necessary.
