F9 M9 Pocket Filter from China Suppliers and Factory - High Efficiency Air Filtration Solutions
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.
- 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.
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.

- 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.
- If the dust concentration in the environment is large, the service life will be shortened.
What is the main function of a synthetic pocket filter?
It is primarily used for intermediate filtration in air conditioning systems to filter 1-5 micron dust particles, protecting downstream HEPA filters and the system itself.
Can the synthetic pocket filter be washed and reused?
Yes, if it is made of washable filter material, it can be cleaned with water or a neutral detergent. It can typically be washed up to two times before needing replacement.
How often do I need to replace the bag filter?
Under normal rated air volume, it should be replaced every 3 to 6 months, or immediately when the pressure resistance reaches 450Pa or higher.
What is the maximum operating temperature for this filter?
The synthetic pocket filter has a standard temperature resistance of 80°C and can withstand a maximum temperature of up to 100°C.
Are custom sizes available for the pocket filters?
Yes, while they fit all commonly used filter frames, other specifications and dimensions can be fully customized according to your specific requirements.
