Kangen machines are real water ionizers... but legitimacy depends on more than working technology. This guide compares Kangen's H₂ output, pricing model, and warranty against Tyent on every spec that matters. If you're weighing a $4,000+ purchase, here's what the numbers actually show.

Alkaline, hydrogen-rich water is backed by real research — but the Kangen SD501 often produces less than 0.5 ppm H₂, below the therapeutic threshold most studies are based on. This guide examines what the peer-reviewed evidence actually shows, where Kangen machines fall short, and how the numbers compare to alternatives at the same price point.
