As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to offer our Polyester flange-clamp air filter designed specifically for HVAC systems in commercial buildings. With an annual export value exceeding US$5 million and a global presence across North America, Europe, Asia, and beyond, we bring decades of expertise to every filter we produce. This 10 micron filter combines high dust-holding capacity with low airflow resistance, ensuring efficient air purification for offices, shopping malls, hotels, and other commercial spaces. Its robust flange-clamp construction simplifies installation and replacement, reducing downtime and maintenance costs.
Our filter media is made from high-quality polyester fibers—a synthetic material known for its excellent moisture resistance, durability, and consistent filtration performance. The 10 micron rating captures a wide range of airborne particles including dust, pollen, mold spores, and fine debris, helping to maintain indoor air quality and protect HVAC equipment from contamination. The flange-clamp frame is engineered to fit securely into standard commercial HVAC ductwork, preventing air bypass and ensuring that all air passes through the filter media. This design also allows for quick filter changes without tools, which is a key advantage for facility maintenance teams.
Key technical specifications:
| Parameter | Value |
| Filter Media | 100% Polyester non-woven |
| Filtration Efficiency | 10 micron (nominal, ≥85% arrestance) |
| Frame Material | Galvanized steel (standard) / Aluminum (optional) |
| Operating Temperature | Up to 80°C (176°F) |
| Relative Humidity | Up to 100% (non-condensing) |
| Initial Pressure Drop | ~30 Pa (at rated airflow) |
| Recommended Final Pressure Drop | 250 Pa |
| Standard Sizes | 20x20x1, 24x24x1, 24x24x2 inches (custom sizes available upon request) |
The polyester media offers several advantages over traditional glass fiber or paper filters: it is washable and reusable (depending on application), which reduces long-term replacement costs. The media also has a high tensile strength and resists tearing during handling. The flange-clamp design eliminates the need for separate gaskets or clips, creating a tight seal that prevents unfiltered air from bypassing the filter. This is especially critical in commercial HVAC systems where air quality standards are strict.
Benefits for your facility:
- Improved indoor air quality – Captures 10 micron particles, reducing allergens and dust accumulation.
- Energy efficiency – Low initial pressure drop means less strain on HVAC fans, lowering electricity consumption.
- Easy maintenance – Tool-free installation and replacement; flange clamp snaps into place.
- Durability – Polyester media resists moisture and microbial growth, extending filter life.
- Cost savings – Reusable media reduces waste and replacement frequency.
- Customizable – Available in various sizes, frame materials, and efficiency grades to match your system.

Frequently Asked Questions (FAQ):
-
Q: Can this filter be washed and reused?
A: Yes, the polyester media can be washed with mild detergent and water for light to moderate dust loads. However, for heavy-duty commercial use, we recommend replacement to maintain optimal efficiency. Please consult our technical team for guidance based on your specific application. -
Q: What is the typical lifespan of this filter?
A: Under normal commercial HVAC conditions (e.g., office buildings), a 10 micron polyester filter typically lasts 3–6 months, depending on air quality and run time. Higher dust loads may require more frequent replacement. The flange-clamp design makes it easy to inspect and change. -
Q: Does this filter meet any industry standards?
A: Our filters are manufactured according to general HVAC filtration practices. While we do not claim specific certifications, we can provide test reports for filtration efficiency and pressure drop upon request. The 10 micron rating is based on standard test methods. -
Q: Can I get a custom size or frame material?
A: Absolutely. We offer custom sizes and optional aluminum frames. Please provide your duct dimensions and desired specifications, and we will produce a tailored solution within your lead time. -
Q: Is this filter suitable for use in hospitals or cleanrooms?
A: This is a general-purpose commercial HVAC filter. For applications requiring higher efficiency (e.g., HEPA), we recommend our other product lines. However, this 10 micron filter can serve as a pre-filter in multi-stage systems. -
Q: How do I install the flange-clamp filter?
A: The filter is designed to slide into standard side-access or top-access filter housings. The flange clamp provides a secure fit—simply push the filter into the track until it locks. No tools are required. Detailed installation instructions are included with each shipment. -
Q: What is the minimum order quantity?
A: For standard sizes, we accept orders starting from 100 pieces. For custom sizes, please contact our sales team for MOQ details. We offer competitive pricing for bulk orders. -
Q: How long does shipping take to North America?
A: From our ports in Tianjin or Qingdao, standard sea freight takes approximately 25–35 days to major US West Coast ports. Express air freight is also available upon request for urgent orders.
