China F6 M6 Bag Filter Suppliers - High Quality Filters from Leading 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 for appearance color
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 primarily used for?
It is mainly used for intermediate filtration in air conditioning and HVAC systems. Typically located in front of HEPA filters, it captures 1-5 micron dust particles to protect the downstream filters and the overall system.
Why choose synthetic filter media over traditional glass fiber?
Synthetic media is manufactured using a thermal melting process, which completely avoids the physical discomfort and shedding associated with old-fashioned glass fiber materials. It also contains electrostatic fibers for excellent sub-micron dust filtration.
Can synthetic pocket filters be washed and reused?
Yes, if the specific filter material is designated as washable, it can be cleaned using clean water or a neutral detergent solution. It must be dried completely before reuse and can generally be washed up to two times before requiring replacement.
What filter efficiency classes are available?
Synthetic pocket filters are commonly available in various efficiency classes according to EN 779 standards, including M5, M6, F7, F8, and F9, allowing you to choose the right efficiency for your specific air quality requirements.
How does a high dust environment affect the filter's lifespan?
In environments with high dust concentrations, the filter will reach its maximum pressure drop (resistance of 450Pa or more) much faster. Consequently, the standard 3 to 6-month service life will be significantly shortened, requiring more frequent replacements.
What are the operating temperature limits for these filters?
The standard temperature resistance for synthetic bag filters is 80°C, but they can withstand a maximum operating temperature of up to 100°C. They can also operate effectively in environments with up to 100% relative humidity.
