Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of expertise since 1998. We specialize in producing high-performance air filtration solutions, and our Factory Direct Air Filter Element with Epoxy Resin Mesh Lining is engineered to deliver exceptional reliability and efficiency. Every filter is 100% leak-tested and fully compliant with ISO 29463, ensuring consistent performance in critical environments. As a direct factory supplier, we offer competitive pricing without compromising on quality, backed by our annual export volume of US$5–10 million to global markets.
Our air filter element features a unique epoxy resin mesh lining that provides superior structural integrity, corrosion resistance, and airtight sealing. This design minimizes bypass leakage and extends service life, making it ideal for high-efficiency applications such as cleanrooms, hospitals, pharmaceutical manufacturing, and commercial HVAC systems. Each filter undergoes rigorous 100% leakage testing using DOP or PAO aerosol methods, guaranteeing zero defects before shipment. With adherence to the international standard ISO 29463, you can trust our filters to meet the strictest classification requirements for fine particle removal.
Key Features & Technical Specifications
- Epoxy Resin Mesh Lining – Enhances mechanical strength, resists humidity and chemical corrosion, and ensures a tight seal between filter media and frame.
- 100% Leakage Test Certified – Every filter is individually tested; no pinholes, edge leaks, or media defects are tolerated.
- ISO 29463 Compliant – Conforms to the international standard for high-efficiency filters, covering MPPS (Most Penetrating Particle Size) efficiency.
- Wide Range of Sizes & Configurations – Customizable dimensions, frame materials (galvanized steel, aluminum, plastic), and gasket options (PU, EVA, silicone).
- High Dust Holding Capacity – Optimized pleat geometry and deep media bed reduce pressure drop while extending replacement intervals.
- Low Initial Pressure Drop – Energy-efficient design reduces fan load and operational costs.
- Applications – Cleanrooms (ISO Class 5–8), pharmaceutical cleanrooms, surgical suites, electronics manufacturing, food processing, and general ventilation.

Frequently Asked Questions (FAQ)
- What is the epoxy resin mesh lining and why is it beneficial? The epoxy resin mesh lining is a protective coating applied to the filter media and frame interface. It reinforces the structure, prevents corrosion, and eliminates air bypass around the filter edges, ensuring maximum filtration efficiency.
- How is the 100% leakage test performed? Each filter is tested using a DOP (Dioctyl Phthalate) or PAO (Polyalphaolefin) aerosol generator with a photometer or particle counter. The entire filter face and seal area are scanned; any leakage exceeding the allowable limit results in rejection.
- What does ISO 29463 compliance mean? ISO 29463 is an international standard for high-efficiency filters and filter media. It defines classification based on MPPS (Most Penetrating Particle Size) efficiency. Our filters meet or exceed the requirements for classes ISO 15 E to ISO 45 H, which are equivalent to H13/H14 HEPA grades.
- Can I order custom sizes or frame materials? Yes, we offer customization. You can specify dimensions, frame material (galvanized steel, aluminum, ABS plastic), gasket type, and even filter media depth. Minimum order quantities may apply, but we are flexible for volume orders.
- What is the typical lifespan of these filters? Lifespan depends on operating conditions (dust load, airflow, humidity). In standard cleanroom environments, replacement intervals range from 12 to 24 months. Our high dust holding capacity design helps extend service life compared to conventional filters.
- Are these filters suitable for pharmaceutical cleanrooms? Absolutely. They comply with ISO 29463 and are widely used in pharmaceutical production, cleanrooms (ISO Class 5–8), and sterile areas. The 100% leakage test ensures no contamination bypass.
- How are the filters packaged for export? Each filter is individually wrapped in a plastic bag and placed in a sturdy carton. For larger orders, we use pallet packing with shrink wrap and corner protectors to prevent damage during shipping.
- What is your minimum order quantity (MOQ) and lead time? MOQ for standard sizes is typically 10 pieces; for custom sizes, please inquire. Lead time ranges from 10 to 25 days depending on quantity and complexity. We maintain stock for popular sizes to expedite delivery.
