The Ewater Machine Water Ionizer is a batch ionizer said to be capable of producing drinkable water within 30 seconds. This is questionable. The HiddenCures ionizer costs less and produces a lot more water, though it will take 1 hour.

Ewater Machine Water IonizerA batch ionizer such as the HiddenCures ionizer has advantages over a flow-through unit such as those make by Jupiter. In its favor, the Ewater Machine is also a batch unit.

  • All flow-through ionizers such as those made by Jupiter that connect to the tap suffer from one major disadvantage: You cannot purify the water as well as you would like. All ionizers require minerals to work, and if you do a really good job of purifying your water and removing the toxins, you will also remove the minerals.

  • Those really serious about water quality use a reverse osmosis or distilled water filter, yet none of the ionizers such as those made by Jupiter that attach to your tap can use one. In order to be sure you have removed all the toxins, you have to remove everything from the water. Then you add back what you want, such as salt.

  • A batch unit is capable of a greater degree of  oxidation reduction potential (ORP) because you can run the ionizer until the desired degree is reached. With a flow through unit, once the water passes through the ionization chamber it is done. A typical flow through ionizer is capable of producing an ORP of about -200 to -300 mV. The HiddenCures unit will achieve this in one or two hours, but it has been measured to produce over -800 mV after 8 hours (the more negative, the greater anti-oxidant power).

If you are convinced that a batch ionizer is what you want, prices for commercial units start at about $1,000 (the Ewater is not what I would consider a commercial unit). However, the HiddenCures unit, without any bells or whistles, sells for under $150.

Note: The pH that an ionizer produces is not important as compared to the ORP. You can easily change the pH of water by adding a few drops of vinegar, or bicarbonate of soda. When it hits your stomach, the pH of the water will not have much effect. It is the negative hydrogen ion (the hydride) with its extra electron that makes ionized water valuable.

Details of the Ewater

This water ionizer is said to be able to produce ionized water in 30 seconds. But it doesn't state the ORP or pH of the resultant water. Since the unit uses two 9-volt batteries, it is reasonable to assume this 18V is the voltage applied to the electrodes. The ion rate crossing a cotton membrane does not appear to be sufficient to produce a useful ORP in just 30 seconds. The HiddenCures unit, operating at 32 volts with a fiber membrane, takes 1 hour to produce a decent ORP. Flow through ionizers use large surface area electrodes and a large power supply to get a gallon of water ionized in one minute. A cotton membrane is not sufficient for large current flow, and 9 volt batteries cannot support such a large current. Also, the materials used for the Ewater's electrodes is not stated in the on-line literature; they could be made of toxic metals.
