What Is a Synthetic Bag Filter ?

A synthetic bag filter is an air filtration device constructed from high-performance synthetic fibers such as polyester (PET) and polypropylene (PP). These fibers are sewn or thermally bonded into multiple pocket-style bags, which are mounted onto a rigid frame. This design offers a large filtration surface area and is ideal for HVAC systems and industrial air purification.

Materials and Construction

Our Synthetic Bag Filters are built from high-grade synthetic fibers, including polyester (PET), polypropylene (PP), and nylon (polyamide), selected through rigorous quality control developed from over a decade of filtration experience.

ClearFilter leverages proprietary wet-process technologies and advanced ePTFE membrane production methods to ensure every material meets strict mechanical strength, chemical resistance, and moisture tolerance standards.

Compared to fiberglass and cotton filters, synthetic fibers offer better durability, enhanced water repellency, and lower risks of fiber shedding or microbial growth, making them ideal for demanding HVAC environments.

Structurally, each filter features a multi-pocket design (typically 5–12 pockets) with precision stitching or ultrasonic welding to prevent air leakage. Frames are available in galvanized steel, aluminum alloy, or rigid plastic, designed to fit diverse installation needs.

Our materials and designs have been trusted by critical industries, including the nuclear energy sector, where ClearFilter filtration solutions protect air, water, and oil systems under extreme operating conditions.

Performance Metrics and Standards

Designed and tested under the highest industry benchmarks, ClearFilter’s Synthetic Bag Filters achieve MERV 8 to MERV 15 ratings per ASHRAE 52.2, and comply with ISO 16890 classifications (ePM10, ePM2.5, ePM1). They are also qualified against legacy EN 779 standards (G4 to F9), ensuring consistent global compatibility.

Filtration efficiency is verified through particle counting and gravimetric methods in ClearFilter’s internal quality labs, supporting our role as a core filtration supplier to China’s nuclear industry.

Each filter is carefully calibrated for optimal airflow, balancing energy efficiency with superior particle capture.

Low initial resistance minimizes the load on HVAC systems, and a recommended final resistance of ≤450Pa ensures timely maintenance.

The high dust-holding capacity (DHC), developed through years of research into fiber structure optimization, reduces replacement frequency and operational downtime for demanding industrial applications.

Advantages and Limitations of Synthetic Bag Filter

Synthetic Bag Filters from ClearFilter offer an ideal balance between performance, durability, and operational cost-effectiveness.

Their high dust-holding capacity and wide filtration range (MERV 8–15 / ePM10–ePM1) meet the diverse air quality needs of commercial buildings, cleanrooms, and energy facilities. Low initial pressure drop reduces HVAC energy costs significantly, a result of ClearFilter’s ongoing innovation in filter media technology.

ClearFilter’s extensive R&D background—including successful development of high-performance filters for nuclear, food, electronics, and manufacturing sectors—ensures that our filters maintain robust resistance against humidity, microbial contamination, and mechanical stress, while eliminating fiber shedding risks associated with traditional media.

However, users should consider installation space, as Synthetic Bag Filters are bulkier than flat-panel types. Proper pocket expansion and tight sealing are essential to avoid air bypass. Additionally, while highly durable, synthetic fibers require careful selection for extremely high-temperature or aggressive chemical environments.
