China M9 F9 Medium Pocket Filter - High-Quality Air Filtration Solutions from Trusted 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 the main advantage of using a synthetic pocket filter?
Synthetic pocket filters offer high burst resistance, extra-long service life, and are completely free from glass fibers. This makes them much safer and more comfortable to handle, while still providing excellent sub-micron dust filtration.
Can synthetic bag filters be washed and reused?
Yes, if the filter is made of a designated washable material, it can be cleaned with clean water or a neutral detergent solution. However, they should typically only be washed up to two times before requiring a full replacement to maintain efficiency.
Where are synthetic pocket filters typically installed in an HVAC system?
They are primarily utilized as intermediate filtration in air conditioning and ventilation systems. They are usually positioned just in front of HEPA filters to protect them from larger dust particles and extend the overall lifespan of the system.
What is the recommended final pressure drop for a synthetic bag filter?
For optimal performance and energy efficiency, the recommended final pressure drop is generally between 400 and 450 Pa. Once the resistance reaches 450Pa or higher, the filter must be replaced.
How do I know when it's time to replace my pocket filter?
Under rated air volume conditions, the filter should be replaced every 3 to 6 months. You should also replace it immediately if the pressure drop reaches 450Pa. Note that in environments with high dust concentrations, the service life will be shorter.
Are custom sizes available for synthetic pocket filters?
Yes, while standard sizes (such as 592×592×600 mm) are readily available to fit all commonly used filter frames, other specifications, dimensions, and bag quantities can be customized according to your specific system requirements.
