M6 F6 Synthetic Pocket Filter - Quality Air Filters from China Suppliers & Trusted 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)
1. What is the main advantage of synthetic pocket filters over glass fiber filters?
Synthetic pocket filters are made from high-performance non-woven fabrics that do not cause skin irritation or discomfort, a common issue with traditional glass fiber materials. Additionally, they feature electrostatic fibers for superior sub-micron dust filtration.
2. Can I wash and reuse these bag filters?
Yes, if the filter material is designated as washable, it can be cleaned using clean water or a neutral detergent solution. It must be thoroughly dried before reuse and can typically be washed up to two times before requiring replacement.
3. Where are pocket filters typically installed in an HVAC system?
They are generally used for intermediate filtration and are installed directly in front of HEPA filters. Their primary role is to protect the downstream high-efficiency filters and the overall system from 1-5 micron dust particles.
4. What is the maximum operating temperature for these filters?
These synthetic bag filters have a standard temperature resistance of 80°C, with a maximum allowable operating temperature of 100°C. They can also withstand up to 100% relative humidity.
5. How do I know when it's time to replace the filter?
You should replace the filter every 3 to 6 months under rated air volume conditions. However, if the system's pressure drop (resistance) reaches or exceeds 450 Pa, immediate replacement is required regardless of the time in service.
6. Are custom sizes available if my system doesn't fit standard dimensions?
Yes. While standard sizes like 592×592×600 mm are readily available and fit most commonly used filter frames, specifications and dimensions can be customized according to your specific system requirements.
