Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million. We are proud to present our Polyester Flange-Clamp Air Filter – a high-performance panel filter designed to deliver 95% efficiency while maintaining a slim 2.5mm thickness. This filter is engineered for demanding HVAC and industrial air purification applications, providing reliable particle capture with minimal airflow resistance. Incorporating our decades of metal and wire mesh expertise, the flange-clamp design ensures easy installation and a secure seal, making it an ideal choice for both new systems and retrofit projects.
The filter is constructed from premium polyester non-woven media that offers excellent dust holding capacity and low pressure drop. The 95% efficiency rating (tested according to ASHRAE 52.2 standard, equivalent to MERV 13-14) guarantees effective removal of fine particles such as dust, pollen, mold spores, and bacteria. The 2.5mm panel thickness allows for tight fit in compact filter housings, while the 60x60cm (23.6x23.6 inches) size is a popular standard for many HVAC units. Whether you are upgrading existing filters or designing a new air handling system, this product delivers consistent performance and long service life.
Key Features & Benefits
- High Efficiency: 95% capture efficiency for particles down to 0.3 microns, ensuring clean air for sensitive environments.
- Ultra-Thin Profile: Only 2.5mm thick – perfect for space-constrained installations without compromising on performance.
- Flange-Clamp Frame: Integrated perimeter flange allows quick, tool-free mounting and removal, reducing maintenance downtime.
- Durable Polyester Media: Resistant to moisture, chemicals, and temperature fluctuations; suitable for continuous operation up to 80°C.
- Low Pressure Drop: Optimized media structure minimizes energy consumption of fans and blowers while maintaining high filtration efficiency.
- Wide Compatibility: Standard 60x60cm panel fits most commercial and industrial HVAC systems, air handlers, and cleanroom pre-filters.
- Eco-Friendly: Polyester material is recyclable, and the filter can be replaced easily without discarding the entire frame system.

Detailed Product Advantages
Superior Filtration Performance: Our polyester media is engineered with a gradient density structure that traps larger particles on the surface and finer particles deeper inside the media. This mechanism provides a 95% efficiency rating while maintaining a low pressure drop, ensuring your HVAC system operates efficiently without overloading fans. The filter is ideal for commercial buildings, hospitals, data centers, and industrial cleanrooms where air quality is critical.
Space-Saving Design: The 2.5mm thickness is a standout feature – it allows the filter to be installed in slim-profile housings and V-bank configurations where traditional pleated filters cannot fit. Despite its thinness, the media is reinforced with a non-woven scrim for dimensional stability, preventing sagging or tearing under high air flow.
Easy Installation and Maintenance: The flange-clamp design incorporates a rigid perimeter frame that slides into matching tracks or clamps. No screws, clips, or additional tools are required – simply insert the panel and secure the clamp. Replacement takes seconds, reducing labor costs and system downtime. The filter can be disposed of easily, and the frame can be reused if desired (optional reusable frame available).
Customization Options: We offer flexible customization to meet specific project requirements. Options include: different frame materials (galvanized steel, aluminum, stainless steel), flange width adjustments, custom sizes (minimum order quantity applies), and color coding for easy identification of filter efficiency. Our factory in Hengshui, Hebei, China, is equipped with advanced production lines and a quality control system that ensures every batch meets your specifications.
Frequently Asked Questions (FAQ)
-
Q: What does the 95% efficiency mean in practical terms?
A: This filter captures at least 95% of airborne particles ranging from 0.3 to 1.0 microns in diameter. It is suitable for controlling fine dust, smoke, pollen, and many bacteria. For reference, it corresponds to an MERV rating of 13 or 14 under ASHRAE 52.2. -
Q: Can this filter be used in high-temperature environments?
A: The polyester media can withstand continuous operating temperatures up to 80°C (176°F). For higher temperature applications, we recommend our fiberglass media filters; please contact us for a custom solution. -
Q: Is the flange-clamp frame compatible with existing filter housings?
A: The standard frame has a 20mm flange width and fits most slide-in and clamp-type housings. We can also customize the flange width or provide a different frame style upon request. Please provide your housing dimensions for a compatibility check. -
Q: How often should this filter be replaced?
A: Replacement frequency depends on the operating environment. In typical HVAC systems, the filter should be inspected every 1-3 months. When the pressure drop reaches 2-3 times the initial value, or when visible dust accumulates, it is time to replace the filter. We can provide a pressure drop monitoring guideline. -
Q: Do you offer custom sizes?
A: Yes, we can produce filters in non-standard sizes. Minimum order quantity (MOQ) for custom sizes is 500 pieces. Please contact our sales team with your required dimensions. -
Q: Is the filter washable or reusable?
A: This polyester filter is not designed for washing; it is a disposable 95% efficiency filter. Washing can damage the media structure and reduce efficiency. For washable applications, we recommend our metal mesh filters or synthetic washable panels. -
Q: What certifications or quality standards do you follow?
A: As a manufacturer since 1998, we implement strict in-house quality control procedures. Our filters are tested according to industry standards (ASHRAE 52.2, EN 779). We do not currently hold third-party certifications, but we can provide test reports for each batch upon request. -
Q: What is the minimum order quantity for standard filters?
A: For standard 60x60cm panels, the MOQ is 100 pieces. For larger quantities, we offer volume discounts and faster lead times. Please inquire for a quotation.
