Science & Validation

Independent Testing.
Validated Results.

RROEE was tested by internationally recognized independent institutions before a single unit was sold.

The lab certificates reference NEARON YDOR — the same product sold in Greece. RROEE is the brand name for the United States and European market.

RROEE is not a filter brand making health claims. It is a science-backed system whose performance has been independently verified — by world-class institutions, using rigorous methods, before a single unit went on sale.

Every claim on this website is grounded in documented test data. The original certificates are available for download below.

Going Further

Molecular Hydrogen — Why It Matters

Most water filters stop at removal. RROEE goes further — enriching purified water with molecular hydrogen for antioxidant activity and cellular hydration support.

Molecular hydrogen (H₂) is the smallest antioxidant in existence — small enough to penetrate cells and neutralize harmful free radicals directly. Peer-reviewed studies associate hydrogen-rich water with reduced oxidative stress, improved recovery, enhanced immune resilience, and more efficient cellular hydration.

RROEE produces hydrogen-enriched water with a negative ORP of approximately −400 mV — naturally, without electrolysis, without chemicals. The result is water with genuine antioxidant capacity and a noticeably smoother taste.

ORP Scale — Oxidation-Reduction Potential
−400 mV (RROEE)0 mV (Tap water)+400 mV (Oxidising)
RROEE water: ~−400 mV  ·  Acts as an antioxidant in the body

ORP (Oxidation-Reduction Potential) measures whether water acts as an oxidant or an antioxidant in the body. Standard tap water has ORP near zero — neutral. RROEE water at −400 mV acts as an antioxidant, supporting the body's natural balance.
