Pre Filter
The First Line of Defense in Industrial Air Filtration Systems
In today’s industrial environments, air quality plays a vital role in production efficiency, employee health, and equipment longevity. That’s why investing in a high-quality Pre Filter—also known as a primary air filter—is essential, especially for facilities equipped with complex HVAC (Heating, Ventilation, and Air Conditioning) systems. Installing Pre Filters at the early stage of air intake helps reduce the workload on downstream filtration units such as HEPA or ULPA Filters, allowing the entire system to perform more efficiently while lowering long-term maintenance costs.
Key Benefits of a Pre Filter
A reliable Pre Filter is designed to capture coarse dust, debris, and large airborne particles before they reach the fine filtration stage. This not only improves air quality from the outset, but also prevents premature clogging of high-efficiency filters, thereby prolonging the lifespan of your final filters and reducing overall operational costs.
Our synthetic Pre Filters are manufactured using high-quality polyester fiber, engineered for durability, stable airflow, and optimal particle retention. They are available in various EU filter grades (EU2–EU4) and thicknesses, suitable for different industrial air handling applications.

Common Industrial Applications of Pre Filters
Initial air filtration in paint booths, spray lines, and air supply plenums
Used as Pre Filters in AHU systems
Can be sewn into pocket filters, filter bags, or laminated with wire mesh.
Can be installed in corrugated aluminum frames as a replacement for paper-frame filters.
Applications of Pre Filters in Industrial and Commercial Environments
- Industrial Facilities: Pre Filters are widely used to trap coarse dust and debris in production areas, such as paint spray lines, air intake points of machinery, and zones with heavy dust accumulation. Installing Pre Filters at these locations helps protect sensitive equipment and maintain stable air quality during operation.
- Air Handling Units (AHU): Pre Filters serve as the first filtration stage in AHU systems. By capturing larger particles early on, they reduce the load on secondary filters such as HEPA or Fine Filters, improving overall filtration efficiency and extending the life of downstream components.
- Commercial HVAC Systems: Common in shopping malls, office buildings, hospitals, and hotels, Pre Filters play a crucial role in maintaining consistent indoor air quality. They act as a barrier against dust, pollen, and airborne contaminants before air reaches occupied spaces.
- Custom-Made Filter Bags: Pre Filter media can be stitched and shaped into various filter bag designs to suit specific applications. These may include wire-supported sleeves or custom-sewn filter pockets, offering flexibility in both industrial and commercial filtration systems.
- Aluminum Frame Conversion with Pleated Design: For users seeking a durable alternative to cardboard-framed Pre Filters, we offer the option to mount the filter media into pleated aluminum frames. This solution enhances longevity and allows for partial cleaning and reuse, making it ideal for long-term cost-efficiency.
