Our panel high-efficiency filters offer multiple efficiency levels such as H13 and H14, achieving filtration efficiency of over 99.99% for 0.3μm particles, with some models reaching ULPA U15/U16 levels. The products are widely used in semiconductor wafer manufacturing, photolithography workshops, chip packaging, microelectronics assembly, and ISO Class 1-7 cleanrooms, as well as in terminal filtration for FFU fan filter units, clean transfer windows, and laminar flow hoods. Our CNAS testing center can conduct scanning leak detection and efficiency tests on each product to ensure compliance with the stringent cleanliness requirements of the semiconductor industry.

Fully customizable. The panel high-efficiency filters can be tailored according to customer drawings or actual operating conditions, including: size specifications (length, width, height, thickness), frame materials (aluminum alloy, galvanized sheet, stainless steel, MDF board, plastic, etc.), filter materials (glass fiber, PTFE, etc.), types of sealing glue, separators (hot melt adhesive, aluminum foil, paper partitions), and more. We offer comprehensive OEM/ODM services, with over 20 years of R&D and manufacturing experience and a professional engineering team to assist customers through the entire process from design drawings, sample verification to mass production.

Jieding has passed ISO 9001, ISO 14001, and ISO 45001 management system certifications and will obtain IATF16949 automotive industry quality management system certification and medical supplies GMP certification in 2024, while also holding international certifications such as European BSC1, US EPA, NSF, and SOP. Our CNAS nationally recognized testing center can issue authoritative test reports, fully meeting the qualification and product compliance requirements of customers in the semiconductor and microelectronics industries.

The Jieding factory covers an area of 50,000 square meters, including 6 clean workshops totaling 20,000 square meters, where panel high-efficiency filters are assembled in a clean environment to prevent cross-contamination. In terms of quality control, we implement a full-process quality management system from incoming materials inspection (IQC), process control (IPQC), finished product inspection (FQC) to outgoing inspection (OQC). Each high-efficiency filter undergoes efficiency testing, PAO/DOP scanning leak detection, and resistance testing at the CNAS testing center to ensure 100% compliance before shipment.

The lifespan of panel high-efficiency filters is generally 1-3 years, depending on the cleanliness of the air in the application environment, operating airflow rate, pre-filter configuration, and daily operating hours. Under normal operating conditions in semiconductor cleanrooms, it is recommended to replace the filter when the final resistance reaches twice the initial resistance or the designed final resistance value. We can recommend the optimal pre-filtering solution based on the customer's actual working conditions to extend the lifespan of the terminal high-efficiency filter and reduce overall operating costs.

The MOQ (Minimum Order Quantity) for standard specifications is generally 50-100 pieces, while that for custom specifications depends on structural complexity, usually starting from 100-200 pieces. We can flexibly negotiate with new customers and sample orders. The lead time for standard stock products is 7-15 days, while the lead time for large custom orders is usually 25-35 days. The company has multiple automated production lines and sufficient raw material supplies to support customers' urgent orders and long-term stable supply needs.

Panel high-efficiency filters are packaged using independent PE bags, pearl cotton/EPE corner protection, and export-grade cartons or wooden cases to effectively prevent transportation shocks and dust contamination. We have rich export experience, with products sold to numerous countries including Europe, the USA, Japan, and South Korea, familiar with customs clearance and packaging standards at various destination ports. We also support neutral packaging, customer brand logo printing, custom color boxes, and multilingual customization of manuals and labels, helping brand owners and traders establish their own brands.
