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 μm 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
Q1: What materials are synthetic pocket filters made of?
These filters are constructed using high-performance non-woven fabric and electrostatic fibers, which avoid the irritation common with older glass fiber materials.
Q2: Can these bag filters be washed and reused?
Yes, if made of washable material, they can be cleaned with water or neutral detergent. They can be washed up to two times before replacement is required.
Q3: When exactly should I replace my pocket filter?
The general replacement cycle is 3 to 6 months, or immediately if the resistance reaches 450Pa or higher.
Q4: What frame options are available for these filters?
Synthetic pocket filters are typically available with Aluminum, Galvanized steel, or Plastic frames to suit different system requirements.
Q5: What is the primary application for these filters?
They are primarily used for intermediate filtration in air conditioning systems to capture 1-5μm particles and protect downstream HEPA filters.
Q6: Are the colors of the filters standardized?
Yes, uniform identification colors are used to make it easy to identify the different filter efficiency classes at a glance.
