On-demand generation with a portable device sidesteps that entirely.\u003c\/p\u003e\n\u003cp\u003eThe H2CAP is the cap-format version of that idea, and in our view one of the most technologically advanced portable hydrogen water generators you can carry. Some people prefer the cap because it works with any standard bottle they already carry, and because it produces water at concentrations in the same practical range as most portable units: 1,000 ppb and up, which sits inside the 1,000 to 1,600 ppb Henry's Law ceiling that peer-reviewed hydrogen water research operates within. The companion H2POD® is a purpose-built bottle for people who prefer that form factor. Same underlying category, two ways to carry it.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-top:1px solid #e3ded3;padding:11px 0;\"\u003e\n\u003csummary style=\"cursor:pointer;font-weight:600;font-size:15px;color:#1f3a2c;\"\u003eAbout this product\u003c\/summary\u003e\n\u003cdiv style=\"padding-top:10px;\"\u003e\n\u003cp\u003eH2CAP is a holistic wellness product.
