About O2-King

Health, engineered — not left to chance.

O2-King exists to put molecular hydrogen research into two objects people actually use: the water you drink every day, and the fifteen minutes you take back for recovery. Oxygen in the name. Hydrogen in every molecule.

Why Hydrogen

A simple molecule, a measurable effect.

Decomposing water molecules into hydrogen and oxygen ions raises hydrogen-ion concentration — a mechanism that selectively neutralizes cytotoxic free radicals without disrupting the body’s normal oxidative processes, first described in Ohsawa et al.’s 2007 Nature Medicine study.

We didn’t invent hydrogen therapy. We engineered it into a countertop purifier and a glass recovery cabin that fit into an ordinary week — no retreat, no protocol, no guesswork.

What We Believe

Three commitments behind everything we build.

Every O2-King product is judged against the same three standards before it reaches a kitchen counter or an office corner.

🔬

01 / Research-Informed

Backed by Published Science

Light, heat and hydrogen therapy are grounded in peer-reviewed research on phototherapy, far-infrared thermotherapy and hydrogen antioxidant effects — not wellness trends.

🏗️

02 / Architectural-Grade

Deep-Penetrating Warmth

Panoramic glass, electronically controlled privacy panels, high-strength metal framing and ergonomic seating — engineered to a building standard, not an appliance one.

⏱️

03 / Everyday, Not Occasional

Designed for Real Schedules

A slim purifier that disappears under the counter. A 15–30 minute cabin session between meetings. Recovery that fits a real week, not a retreat.

How We Build

The details that don't show up in a photo.

The parts of the product you can’t see in a render are usually the ones that matter most.

01

Five-Stage Filtration

PP cotton, UDF granular carbon, CTO sintered carbon and 0.0001-micron RO filtration — no chemical additives, ever.

02

Ion Electrolysis 4.0

Physical hydrogen production locks hydrogen molecules into water so the body can genuinely absorb them, even after heating.

03

3-Year RO Membrane

Higher-grade membrane sheets rated for three years of service — beyond the two-year standard most filter cores carry.

04

Electronically Controlled Glass

Cabin walls switch between transparent and frosted automatically or manually, without sacrificing the open, airy feel.
