KORTECH KOREA Co., Ltd., the All-In-One Filter Specialist behind SFLUX — a Korean water-technology company with three decades of RO and filtration engineering, manufactured through our production partner in Shanghai, China.

We Research One Thing: Water
From Filter Media to Finished Product

KORTECH KOREA Co., Ltd. is a Korean water-technology company and an all-in-one filter specialist behind SFLUX. From designing RO membranes, carbon block, UF and nano-positive filter media, to engineering finished pitchers and shower filters, our Korean R&D team leads the entire process — manufactured at the Shanghai, China facility of our production partner, KORTECH Environment Equipment Co., Ltd.

We support brand-specific customization, including specifications, logo printing, packaging and filter configuration, and have grown alongside global distribution partners.

SFLUX is where that expertise reaches consumers directly: the same filtration engineering behind KORTECH's OEM/ODM partners, built into products people use at home every day.

Our Principle

Performance Comes First. Always.

Every material, every filter stage, every mechanical part is chosen for what it does to the water, not for what it costs to produce. When performance and convenience conflict, we build around performance.

In-House
Filter media designed, tested and produced at our own Shanghai facility, not outsourced.
20+ Instruments
Every batch verified in our in-house lab before it ships.
Multi-Stage
We layer filtration stages rather than rely on a single shortcut filter.
20+ Years
Two decades of RO and filtration patents inform every new product.
