Hydrogen water machine: what it is and how to choose one in India

Hydrogen water, ORP and ionizers explained. Why a good alkaline water ionizer is also a hydrogen water machine, and what numbers to look for.

What a hydrogen water machine does

A hydrogen water machine dissolves molecular hydrogen into drinking water. Hydrogen is what gives the water a negative ORP, its antioxidant potential. There are two ways to make it: a small electrode in a bottle, or a full water ionizer that produces hydrogen as part of electrolysis.

Ionizer or bottle?

  • Hydrogen bottles are portable and cheap, but hold 300 to 500 ml, take several minutes per fill, and do not change pH or give acidic water.
  • Water ionizers make hydrogen-rich alkaline water on tap, at the flow of your kitchen, and also give purified and acidic water. For a family, an ionizer is the practical choice.

The two numbers to check

  • Dissolved hydrogen, in PPB. The IonX 1101 is designed for up to 1600 PPB.
  • ORP, in millivolts. Negative is good. The IonX 1101 reaches -750 mV depending on source water and level.

Both numbers depend on your water's minerals and the level you select, which is why AlkaFresh calibrates each machine at installation.

Drink it fresh

Hydrogen leaves an open glass within an hour or two. Drink straight from the machine, or fill a closed bottle to the top.

What to look for in India

Platinum-coated titanium plates, an SMPS power supply, calibration to your water, automatic cleaning, and service in your city. See the technology or book a demo and measure the ORP yourself.
