Established in 2002, ZONE is an innovative manufacturer integrated with R&D, production and sales of ceramic filter media.

We own three subsidiaries: Zone Water Treatment, Zone New Materials and Zone Environmental Protection, specialized in filter media for household filters, circulating water filtration media and large-scale water treatment projects separately. As an industry-leading source manufacturer, we run 3 production bases, 2 independent R&D & quality testing laboratories, and a university joint research and analysis center, realizing full self-controlled industrial chain from fundamental research to mass production.

Our core technical team is headed by our founder (PhD of Materials Science) and a university professor acting as Technical Vice President. We maintain long-term industry-university-research cooperation with Shanghai Tongji University and Shandong University of Technology. Backed by robust research capacity, we independently developed SMT Intelligent Surface Modification Technology and exclusive PCAS Precise Pore Size Control Technology. Matched with long-acting slow-release techniques, ZONE has achieved revolutionary upgrades in three core filter media indicators: functionality, service lifespan and physical structure, building solid technical moat.

Our products are marketed in over 50 countries and territories worldwide. As a trusted core supplier to 500+ water treatment enterprises and premium Amazon shower filter brands, we deliver high-performance filter media widely deployed in shower filters, water purifiers, filter cartridges, carbon blocks, circulating water filtration facilities and large-scale water pre-treatment systems.

We have obtained ISO9001 certification, and all products meet international authoritative standards including NSF, FDA, REACH and RoHS. In line with filtration criteria of the US, Japan and Europe, we fully secure product safety and stable performance.

Supported by in-house R&D and full-chain service capability, ZONE provides one-stop services covering product development to performance optimization. We empower all partners to jointly boost high-quality development of the global water purification industry.
