China M9 F9 Medium Pocket Filter - Quality Air Filters from Reliable Suppliers and 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 synthetic pocket filters?
They are made from high-performance non-woven fabric without glass fibers, making them safer for handling. They also contain electrostatic fibers that provide an excellent filtering effect on sub-micron dust.
Where are synthetic pocket filters typically installed?
They are used for intermediate filtration in HVAC and air conditioning systems, usually placed right in front of HEPA filters to protect the lower filters and extend the overall system's lifespan.
Can I wash and reuse a synthetic bag filter?
Yes, if the specific filter material is designated as washable. It can be cleaned with water or a neutral detergent solution, dried, and reused up to two times before requiring a full replacement.
What is the recommended final pressure drop?
The recommended final pressure drop for optimal performance and energy efficiency is generally between 400 and 450 Pa. Once it reaches 450Pa or higher, the filter must be replaced.
Do you offer customized sizes for pocket filters?
Yes. While we offer standard sizes that fit all commonly used filter frames (such as 592×592×600 mm), other dimensions and specifications can be fully customized according to your specific requirements.
What temperatures can these filters withstand?
Our synthetic pocket filters have a standard temperature resistance of 80°C and can withstand a maximum temperature of up to 100°C, operating safely at 100% relative humidity.
