China M9 F9 Medium Pocket Filter - Quality Air Filters from Reliable 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?
The filter material is made of high-performance non-woven fabric using a thermal melting process. This avoids the discomfort typically caused by old-fashioned glass fiber materials. It also contains electrostatic fibers for an excellent filtering effect on sub-micron dust.
Where are pocket filters typically installed?
Pocket filters are suitable for intermediate filtration in air conditioning systems and are typically located directly in front of the HEPA filter to protect the system and the lower filters.
How often do I need to replace the bag filter?
Under rated air volume conditions, the filter should be replaced every 3 to 6 months. It must also be replaced if the resistance reaches 450Pa or more. Environments with high dust concentrations will shorten this service life.
Can synthetic pocket filters be washed and reused?
If the filter material is designated as washable, it can be washed with clean water or a neutral detergent solution. It should be dried completely before reuse. Generally, it can be washed up to two times before it needs to be replaced.
What are the main advantages of using these filters?
They offer an extra-long service life, high burst resistance, a large surface area, and high efficiencies at low pressure drops. They also fit all commonly used filter frames and use uniform color identification for easy recognition.
