It means you’re covered by our Must Be Happy 365-Day Money-Back Guarantee. Your full year starts the day your machine arrives. If after using it for a year you’re not satisfied, simply send it back. Once we inspect it, you’ll receive a full refund for your machine — no questions asked. (Shipping costs are not refundable.)

The PureONE produces 833 ml/min of hydroxy. When this gas is passed through a bubbling stone in our drinking water bottle, it can infuse 1 L of water in 10 minutes at 100% duty cycle. That process yields about 0.8 ppm of molecular hydrogen.

That may seem lower than some advertised hydrogen bottles, but direct comparisons are difficult because we are not infusing with hydrogen alone. The oxygen produced by the PureONE remains dissolved in the water longer than hydrogen and effectively occupies space that limits further hydrogen absorption.

Molecular hydrogen is only one component of the benefits we produce; your infused water also contains EZ gel and EXW, which are present only when hydroxy is mixed with the water (as opposed to hydrogen alone). There is a minimum required infusion time but no strict maximum: after 10 minutes you will have reached maximum saturation—more time won’t increase the dissolved hydrogen concentration, although it won’t harm the water.

Independent lab certificates are not necessary because affordable, easy-to-use tools exist to measure hydrogen. You can search for a hydrogen meter, and we sell an ORP meter that includes H₂ measurement among its features.

"And, if it is a mixture, what is the exact percentage of H₂ in the gas produced?"

PureONE is a mixed-gas machine commonly called an HHO or hydroxy generator. It produces a consistent mixture: approximately 66% molecular hydrogen and 33% oxygen.

Adjusting the percentage control on the front of the machine changes the gas production rate, not the gas composition. Lowering the setting reduces the amount of gas delivered; if you add the gas to your breath, it mixes with ambient air and the effective concentration decreases.
