China F9 M9 Pocket Filter Suppliers - High-Quality Air Filtration Solutions from Trusted Factory
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.
- 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.
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.

- 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.
It is primarily used as an intermediate filter in air conditioning systems to capture 1-5 micron dust particles, protecting both the system itself and downstream HEPA filters.
Yes. The filter material is constructed from high-performance non-woven fabric using a thermal melting process, which completely avoids the skin and respiratory discomfort often caused by traditional glass fiber materials.
If you select our washable filter material option, it can be cleaned with plain water or a neutral detergent solution. After drying, it can be reused. We recommend washing it up to a maximum of two times before full replacement.
The standard temperature resistance is 80°C, but the filter can withstand a maximum peak operating temperature of up to 100°C.
Generally, the filter should be replaced every 3 to 6 months under rated air volume. However, if the environmental dust concentration is high, or if the pressure drop (resistance) reaches 450Pa, it must be replaced immediately.
Yes, while our standard sizes fit most commonly used filter frames, we can fully customize the specifications and dimensions according to your specific system requirements.
