Many believe regular water contains hydrogen, but the hydrogen in water (H2O) is tightly bound with oxygen, making it inaccessible for our bodies to utilize directly. 
Since our cells cannot extract hydrogen from water molecules, the hydrogen in regular water lacks effective antioxidant properties.

H2CAP & H2CAP Plus: Smart Hydrogen Water Bottle Technology


H2CAP is an advanced portable hydrogen water bottle utilizing cutting-edge electrolysis technology. This device effectively separates oxygen and hydrogen within water, enriching the water with high concentrations of molecular hydrogen (H₂). 
This molecular hydrogen acts as a potent antioxidant, easily absorbed by our bodies, offering potential health benefits.

  1. Pocket-sized ultra-compact, ultra-lightweight design

  2. On-demand production of fresh and potent hydrogen water

  3. Supplies high-concentration molecular hydrogen through Platinum PEM.

  4. Excellent antioxidant effects for enhanced health management

What Makes H2CAP the Best Hydrogen Water Generator


Certified Quality You Can Trust
  1. JHPA-Certified: 
    H2CAP is the only portable hydrogen water generator certified by the Japan Hydrogen Water Promotion Association (JHPA).

  2. Rapid Hydrogen Generation: 
    Produces over 1000 ppb of molecular hydrogen in just 3 minutes and 30 seconds.
World-Leading Technology
  1. Two-Chamber, 9-Layer System: 
    Utilizes a dual-chamber structure with platinum-coated PEM (Proton Exchange Membrane) and platinum-titanium electrodes for optimal hydrogen purity and efficiency.
    ​
  2. Exceptional Performance: 
    H2CAP is the world’s smallest hydrogen water generator — yet it delivers the strongest performance in the shortest time.

Whether you're at home, in the office, or on the go, H2CAP brings next-generation hydrogen water to your lifestyle ​
