Reviews

Independent, unsponsored reviews of hydrogen water bottles, generators, pitchers and tablets. Every review states plainly what we have verified and what we have not.

How Products Are Evaluated

We do not operate a laboratory and we have published no measurements of our own. Our evaluation method sets out exactly what we verify, what we do not, and the reagent titration procedure we commit to for any future hands-on measurement.

What we actually do: we check advertised figures against published physical constants and manufacturer documentation, audit specifications and third-party certifications, synthesise verified-buyer reports, and report where a claim and the evidence disagree.

One unit — the PIURIFY bottle — we own and have handled. Everything else is assessed from published sources, and each review says so.

Price, brand reputation and affiliate commission rate have no influence on placement. A unit places well when its published specifications are clear, its certifications are verifiable, and its claims survive scrutiny.

Safety Checks Are Not Optional

A device that publishes no gas-separation detail, names no membrane grade, or carries no identifiable manufacturer is not recommended here regardless of its advertised PPM figure. For the underlying safety framework, see the safety reports, and in particular the ozone gas warning.
