What KYK Co. does
KYK Co., Ltd. is a privately-held Korean water technology company headquartered in Seongnam-si, Gyeonggi-do, where it operates combined headquarters, R&D center, and manufacturing facilities (including the dedicated KYK Water Science Center). Founded in 1980 and led by founder-CEO Kim Young-Kwi, KYK designs and manufactures alkaline water ionizers, hydrogen water generators, portable hydrogen water devices, and replacement filters for global consumer, healthcare, and OEM/ODM distribution. Its proprietary technology stack centers on PEM and diaphragm electrolysis with 99.99% platinum titanium electrode plates, a 12/14-plate double chamber configuration, SMPS power control, and a 4,000-step current control system for precise pH adjustment, backed by 20 patents.
The company's commercial model is hardware-led with a recurring consumables tail: one-time sales of alkaline ionizers and hydrogen generators, ongoing replacement filter revenue, and OEM/ODM white-label services for partners seeking branded, redesigned, or color-customized products. KYK distributes via its own e-commerce site (kykok.com) with international shipping, an inquiry-based global distributor recruitment system, and direct OEM/ODM contracts. Its customer base spans health-conscious consumers, hospitals and oriental medicine clinics, and wholesale/OEM partners.
KYK differentiates on regulatory and clinical credibility rather than price: it holds the world's first IRB-approved water clinical trial (Seoul National University Hospital, 85.7% IBS efficacy, published in Hindawi in 2018) plus a comprehensive certification portfolio including FDA medical device registration, CE, CE RoHS, KFDA medical device manufacturing license, GMP, KC, NRTL, ISO 13485, ISO 9001, ISO 14001, HALAL, KOTRA Global Brand, and ASIA LOHAS.
