Application
The synthetic 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.

Solve Your Filtration Challenges
Different HVAC environments require different filtration solutions. Choosing the right synthetic pocket filter can improve airflow stability, reduce maintenance frequency, and optimize operating costs.
1. High Dust Environments
Filters clog too quickly in dusty HVAC applications, leading to frequent replacement and unstable airflow.
Our Solution
Our high dust holding pocket filters feature thicker synthetic media for extended service life and improved dust retention.
2. Cost-Sensitive Commercial Buildings
Many commercial HVAC systems require reliable filtration while maintaining operational budgets.
Our Solution
Our economic series provides stable filtration performance with a cost-effective structure for daily HVAC operation.
3. High Standard HVAC Applications
Hospitals, clean areas, and premium buildings require stable filtration efficiency and reliable filter structure.
Our Solution
Our premium synthetic pocket filters are designed for demanding HVAC environments with consistent airflow and enhanced durability.
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
Professional Difference Analysis Of Mid-Effect Pocket Air Filter
Adaptability of industrial scenarios
| Scene Demand | Recommended | Reasons |
| Pharmaceutical/food factory | PTFE laminated glass fiber pocket filter | Aseptic environment requirements, no loss of fiber risk |
| Chemical Workshop (Corrosive) | Glass fiber pocket filter | The strongest chemical resistance |
| Commercial HVAC systems | Synthetic bag filter | Low resistance and energy saving |
| High humidity (>85%) | Rigid pocket filter | Moisture-proof structure is better than synthetic pocket filter |
| Commercial kitchen ventilation | Rigid pocket filter | High frequency structure resistant to grease corrosion |
| Electronic clean room | Synthetic pocket filter | Low resistance loss and energy saving, need to install a rear HEPA |
Preferred price/Performance ratio: synthetic fiber pocket filter suitable for most common scenarios
High-end reliable solution: Fiberglass pocket filter for harsh environments
Compromise: Rigid pocket filter performs well in wet/vibrating environments
How often should bag filters be replaced?
Replacement Cycle:
- Under the rated air load, 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.

QUESTIONS AND ANSWERS
Q1: Can You Cut Flat Before Rolling Up On The Paint Stop Filters?
A1: Most Of The Paint Stop Filters On The Market Are Cut Flat After Rolling Up Because It Is Very Easy Operate, There Will Be A Problem That The Edge Is Not Flat. Certainly, We Can Cut Flat Before Rolling Up, Which Can Be Up To 2.6m Wide.
Q2: How Did You Pack HEPA Filter?
A2: One Unit Is Packed With PE Bag Put In 5-layer Carton. If The Customer Is Worried About The Transportation Process, We Can According To The Requirements Of The Form Of Beating Bracket + Corner Protection + Wrapping Film Packing.
Q3: Have HEPA Filter Passed The DOP/PAO Leak Test?
A3: Sure, Our HEPA Filter Is 100% Able To Pass The PAO Test. Because We Will Do An Integrity Test Of Each HEPA Filter For Efficiency And Leakage Before Shipment And Provide A Corresponding Test Report. Any Leakage Will Be Regarded As Unqualified Products And Reworked. We Are Using MPPS Scan Test For HEPA Filter Integrity Test Which According To EN 1822 Standard.
The Scanning Tracks Will Cover The Area:
Inside Filter Material, Sealant, Filter Frame, Corners, Gasket, Seal Of The Filter Mounting Assembly, The Sealant Between Filter Frame And The Gasket
Q4: How Long Does It Usually Take For Me To Receive The Goods?
A4: Depends On Whether You Want To Do Customization Your Air Filters Or Not, And Depends On The Speed Of Customs Clearance And Logistics, But We Can Guarantee To Ship Regular Air Filter In Less Than 7-10 Business Days, And We Have Customers In Singapore Who Received The Goods In Less Than 2 Weeks After We Ship Out.
