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 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 micron 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 Guidelines:
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, dried, and then reused. (Washable up to two times).
High dust concentration environments will shorten the service life.
Frequently Asked Questions
Q1: What materials are used in these synthetic pocket filters?
They are made of high-performance non-woven fabric using a thermal melting process and contain electrostatic fibers for efficient sub-micron dust filtration.
Q2: Where are these filters typically used in HVAC systems?
They are used for intermediate filtration, usually placed before HEPA filters to extend the life of high-efficiency filters.
Q3: How do I know when to replace the bag filter?
The filters should be replaced if the resistance reaches 450Pa or after 3-6 months of use under rated airflow conditions.
Q4: Can these filters be cleaned and reused?
Yes, if the material is washable, you can clean it with water or neutral detergent up to two times before needing a full replacement.
Q5: What is the maximum temperature limit for these filters?
The normal temperature resistance is 80°C, but they can withstand a maximum temperature of up to 100°C.
Q6: Do these filters come in different sizes?
Yes, while standard sizes are available in our technical table, other specifications can be customized according to specific requirements.
