Fill it with water, press the button once and wait for the cycle to finish. Give it a shake, take off the cap and drink. Full instructions come in the box.

Tap, filtered or bottled water all work. Avoid adding powders, juice or anything else to the bottle while a cycle is running.

Cycle length varies by model and is listed on each product page. Longer cycles produce a higher concentration.

Our generators use an electrolysis membrane rather than a consumable filter, so there is nothing to buy on a schedule. Replacement parts are listed under Accessories if you ever need one.

Charge over USB-C with any standard cable. A full charge covers several cycles. The charging indicator is explained in the manual.

It is ordinary water with additional molecular hydrogen (H2) dissolved into it as a gas, similar to how sparkling water holds CO2.

Not in the same form. In H2O the hydrogen is chemically bonded to oxygen. Molecular hydrogen is two hydrogen atoms bonded to each other, dissolved as a gas.

You will see bubbles rise, but it is not fizzy like carbonated water. Most people describe it as light and clean.

Concentration is listed on each product page in ppm. Keep in mind it depends on both the ppm figure and the volume of the bottle, so compare both.

Molecular hydrogen is an active area of research, but we do not make health claims about our products and nothing here is medical advice. We sell a well-built generator that dissolves hydrogen into your water. If you have a health condition, talk to your doctor.

Rinse the glass with warm water after use and let it air dry. A soft bottle brush is fine for the inside.

No. Do not put the base in the dishwasher or submerge it, since it holds the electronics. Hand wash the glass only.

Mineral deposits from hard water can build up over time. Rinse regularly and use filtered water if it becomes noticeable.
