Question #1: How does a water ionizer work?

Answer: The machine filters regular tap water of contaminations and bacteria, after which it passes the purified water through the process of electrolysis to produce alkaline and acidic water.

Read this article regarding the electrolysis process to learn more about the functioning of water ionizers if you want an in-depth look at these machines and what stands behind the curtain.

Question #2: Is there any water waste in its operating process?

Answer: No, as opposed to reverse osmosis systems that generally waste three times the water they purify, the alkaline ionizer does not produce any water waste whatsoever. This is good for the environment as well as your wallet seeing how the utility bills won’t skyrocket after you install it.

Question #3: What is ORP?

Answer: It is the electrical charge required to reduce oxidation. For alkaline water to be beneficial for consumption, the ORP rating on the machine must be negative, and as low as possible.

The -1,050mV negative ORP value of the Tyent UCE-11 water ionizer makes it one of the most efficient machines when it comes to the antioxidant properties of the water it produces.

Question #4: Will it work if the water is hard?

Answer: Yes, but make sure that you look into a model that features a pre-filter that removes contamination specific to hard water, like iron and fluoride. Bear in mind that internal cleaning of the machine is required more often when dealing with hard water as well, as scale buildup occurs much faster.

Question #5: Does the alkaline ionizer work for well water?

Answer: Yes, but you should opt for a machine that features a pre-filter that tends to reducing water contamination with hydrogen sulfide, iron, and calcium, three of the most common issues with well water. If the machine does not feature the right pre-filter to tend to this issue, the purity and quality of the ionized water it produces will be compromised.

Question #6: What contaminants does it generally remove?

Answer: There is a wide range of contaminants polluting tap water and their effect on human health is negative, in some cases, like with lead water pollution, having disastrous health implications in the long-run. As water ionizers feature pre-filters and filter cartridges, they remove most contaminants, including chlorine, chloramines, bacteria, microorganisms, sediments, heavy metals, and more.

One of the most effective alkaline ionizers when it comes to water purification is the Next Generation M11 reviewed here. Aside from treating toxins and trapping sediments, it reduces chlorine and chloramine content in the water you drink.
