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 a washable filter material, it can be washed with clean water or a neutral detergent solution, dried, and then used. It can be washed up to two times before replacement.
- If the dust concentration in the environment is large, the service life will be shortened.
Frequently Asked Questions (FAQ)
What materials are used in synthetic pocket filters?
The filter material is made of high-performance non-woven fabric containing electrostatic fibers, processed via thermal melting. This avoids the discomfort associated with traditional glass fiber materials.
Where are pocket filters typically installed in an HVAC system?
They are suitable for intermediate filtration in air conditioning systems and are generally located directly in front of the HEPA filter to protect it from larger particles.
Can synthetic pocket filters be washed and reused?
Yes, if the filter material is designated as washable, it can be cleaned with clean water or a neutral detergent solution, dried, and reused up to two times before needing a full replacement.
What is the maximum operating temperature for these filters?
The standard temperature resistance is around 80°C, but they can withstand a maximum temperature of up to 100°C under specific operational conditions.
What particle sizes do these filters capture most effectively?
They are mainly used to filter 1-5 micron (sub-micron) dust particles, effectively protecting the lower filters and the entire air conditioning system.
How do I know when it's time to replace the bag filter?
You should replace the filter every 3 to 6 months under rated air volume, or immediately if the system resistance reaches 450Pa or more. High dust environments will also shorten this lifespan.
