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 documentation required before any future HWS measurement is published.
What we actually do: we check advertised figures against published physical constants and manufacturer documentation, check specifications and the stated scope of available third-party reports, distinguish attributed buyer feedback from measurements, 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.
