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.
Key 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 color for easy recognition
Application
The pocket filter is suitable for intermediate filtration in air conditioning systems. It is strategically located in front of the HEPA filter to extend the life of the entire system.
It is mainly used to filter 1-5 micron dust particles to protect both the lower filters and the system itself. Key advantages include low resistance and handling large volumes of air. Optional styles include bag type, frame type, and combination type.

How often should bag filters be replaced?
Replacement Cycle & Guidelines:
•Under rated air volume, replacement is typically required every 3 - 6 months.
•Filters must be replaced if resistance reaches 450Pa or more.
•For washable materials, clean with water or neutral detergent and dry. Do not wash more than twice before replacement.
•Service life will be shortened in environments with high dust concentrations.
Frequently Asked Questions
Q1: What materials are used in synthetic pocket filters?A: They are made from high-performance non-woven fabrics with electrostatic fibers, created using a thermal melting process for superior filtration without the irritation of glass fibers.
Q2: What is the main purpose of a pocket filter in an AC system?A: It acts as an intermediate filter, capturing dust particles between 1-5 microns to protect HEPA filters and the overall HVAC system from clogging.
Q3: When exactly should I replace my bag filters?A: You should replace them every 3-6 months under normal conditions, or immediately if the pressure resistance exceeds 450Pa.
Q4: Are these filters washable?A: Yes, if the specific material is designated as washable. They can be cleaned with water or neutral detergent up to two times before needing replacement.
Q5: Can the dimensions be customized?A: Yes, while there are standard sizes like 592x592x600mm, other specifications can be customized to fit your specific filter frames and requirements.
Q6: What types of frames are available for these filters?A: We offer frames in Aluminum, Galvanized steel, or Plastic to match different installation environments and budget needs.
