What Filteren does
Filteren Co., Ltd. (フィルタレン株式会社) is a Japanese specialty manufacturer of sintered porous plastic filtration products, established in its current corporate form on September 9, 2003, in Toda City, Saitama Prefecture, as a wholly-owned subsidiary of Prumateruzu Co., Ltd. (which in turn operates within the broader Sojitz Group). The company's core technology, inherited from Kaken Co., Ltd.'s research dating to 1970, is the thermal sintering of polyolefin powders (polyethylene and polypropylene) to produce continuous-pore filter structures with pore sizes ranging from 5μ to 300μ. Unlike foam or adhesive-bonded porous materials, Filteren's process yields molded parts and sheets with no closed cells and no risk of foreign-matter contamination, a property that makes the products suitable for medical analytical equipment and pharmaceutical applications in addition to general industrial filtration.
The product portfolio comprises three lines: standardized Filteren Sheets (500×1,000mm, 1.0–3.0mm thickness), custom sintered molded parts (with extensive part-number series including XPE, UPE, SPE, BPP, and BPE families), and the underlying sintered porous-body technology. Filteren offers more than 2,000 product variants serving industrial air filtration (HVAC, factory ventilation, gas/dust intake), industrial liquid filtration (petroleum, chemicals, water/wastewater, food, cutting oils), and medical/analytical equipment. Manufacturing is conducted at the Toda headquarters and at a Philippines facility that has been in operation since 2014 after a transfer of production from China. The company holds ISO 9001 (quality) and ISO 14001 (environmental, June 2022) certifications.
Commercially, Filteren operates a direct B2B, made-to-order model: customers submit drawings and specifications, Filteren designs and produces custom parts (including creation of dedicated tooling), with minimum order quantities of 100 sheets for standard products and project-based lead times and initial costs for custom-molded parts. Sales are generated via direct phone/fax/email consultation and a corporate website; there is no public pricing, no disclosed distributor channel, and no e-commerce transaction flow. The company is led by Representative Director and President Ikegami Toshikazu (池上 俊和), has a registered capital of 80 million yen, and has no disclosed headcount or revenue figures.
