F7 M7 Bag Filter - High-Quality Air Filtration Solutions from China Suppliers & Factory
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 made of?
It is manufactured from high-performance non-woven fabric using a thermal melting process. It also contains electrostatic fibers that provide an excellent filtering effect on sub-micron dust.
What are the main features of a synthetic bag filter?
Key features include an extra-long service life, high burst resistance, large surface area, compatibility with commonly used filter frames, and high efficiency at low pressure drops.
Where are pocket filters typically applied?
They are widely used for intermediate filtration in air conditioning systems, usually located just in front of the HEPA filter to capture 1-5 micron dust particles and protect downstream equipment.
What is the recommended final pressure drop for these filters?
The recommended final pressure drop for our synthetic pocket filters is between 400 and 450 Pa.
How often should I replace my synthetic pocket filter?
Under rated air volume, it should be replaced every 3 to 6 months. However, if the resistance reaches 450Pa or if the environment has a high dust concentration, it must be replaced sooner.
Can synthetic pocket filters be washed and reused?
Yes, if the specific filter material is washable, it can be cleaned with clean water or a neutral detergent solution. It can be washed and dried up to two times before it requires full replacement.
