A Bit More About Water Ionizers

Using a water ionizer provides you with clean water, plus two more products: alkaline and acidic water. We’ll tell you a bit more about the things you need to look out for when choosing a water ionizer, how it works, and the most popular ways to use alkaline and acidic water.

How does the Water Ionizer Work?

Alkaline water is believed to be very beneficial to us, and there are many ways to produce it or to acquire it from natural sources, but these methods can’t be standardized or studied.

Medical research is more concerned with alkaline water ionized by electrolysis. This is the only procedure they could replicate in the same way exactly so they have an opportunity to study its effects and side effects.

Passing a small current through two metal electrodes submerged in a water tank starts a process called electrolysis. It simply separates the acidic minerals in water from the alkaline minerals.

The setting you choose controls how far this separation operation would go. Longer durations or higher currents allow you to get water with a pH ranging from 2 to 12.

The actual pH scale starts at pH1 which is the most acidic and ends at pH14 which is the most alkaline. Regular water is pH7 and that’s what we consider the neutral point.

The ionization of water causes it to have antioxidant properties as a result of the negative Oxidation Reduction Potential (ORP) in addition to the increase in pH value.

This whole process takes around 30 seconds, and it could render a liter of alkaline water in that short time. That’s why a countertop water ionizer doesn’t stall in producing the alkaline or acidic water that you need.

How to Choose a Water Ionizer?

The best water ionizers have a few essential features that’ll give you the most value for the cost. Bear in mind the water profile in the area you live in and your domestic needs.

Number of Plates

The number of plates is an indicator of the amount of alkalinity and antioxidant power. Water ionizers have 3-11 plates, but we’ve seen models with as many as 17. Your regular needs would mostly be fulfilled with 9 or 11 plate ionizers.

Filtration

Clean water is achieved by proper filtration. Some models are very basic with their prefiltration, they employ one stage of simple filtration, which could be sufficient if your tap water quality is already good. A more advanced two-stage filtration system is much better.

The life-span of the filter cartridges and the capacity of filtration are also key factors. Most cartridges require changing after 6-8 months, less than that is too troublesome.

The cost of replacing your filters should also be considered, and so is the ease of their installation.

Cleaning Cycle

Some water ionizers come with an automatic self-cleaning option. The plates reverse their polarity, and other processes are performed after a preset schedule of usage.

The other option is manually cleaning the filter. We’d certainly prefer the automated model.

Alkalinity and Acidity Settings

The pH range you typically need is about 8.5-9.5, however, there are other uses for ionized water, as we mentioned above.

The more advanced water ionizers could offer a pH range from 2-12, which is very broad. Choose the model that fits your needs. This feature would be translated clearly in the price tag.

ORP Level

ORP is the oxidation-reduction potential of ionized water, which is believed to be its ability to neutralize free radicals. A negative value for ORP is considered a good thing. Figures around -600 to -800 are considered very good.

Ease of Installation

Countertop units should be easy to install, often by just connecting them to the kitchen sink faucet.

If a product comes with more demanding schemes or requires professional help to set up, you might want to choose another water ionizer.

Why Alkaline Water is so Popular

Alkaline water is a domestic product nowadays, there’s a noteworthy buzz around it, and you can pick it off the shelf of any supermarket. These are some of the reasons why it’s gaining social momentum.

Acts as an Antioxidant

Antioxidants are the main line of defense against free radicals. Think of it as a standoff between the good guys who promote good health and the bad guys who cause sickness. In our day and age, there are plenty of contaminants that need to be neutralized. Detox systems are good, and purified water is even better.

Quick Hydration

The body responds better to alkaline water than regular drinking water. Being smaller in size, the ionized water molecules are absorbed more readily in the cells, giving a feeling of refreshment and cooling off.

Boosts the Immune System

Stress, toxins, and a bad diet all conspire against the immune system and weaken it. They seem to thrive in a generally acidic medium, and introducing alkaline water neutralizes that favorable condition. This allows the immune system to get a much-needed break, and it eventually regains back its vitality.

Fortifying the Bones

Enhanced ionized water contains minerals like calcium and magnesium which strengthens the bones and teeth if you intake the right amounts.

Neutralizes Excessive Acids

The human body can become quite acidic with stress, an unhealthy lifestyle, and poor nutrition. Drinking alkaline water is an easy fix to neutralize that extra acidity, and it quickly brings back the digestive system to its stable state.

Washes off Pesticides

Using alkaline water with a pH over 10.5 to clean fruits and vegetables can remove the pesticide traces clinging to the skins of the produce. This makes them much safer to eat raw or cooked.

Some Uses of Acidic Water

According to several manufacturers of water ionizers, acidic water shouldn’t be discarded as it could be useful. Here are some of their recommendations:

Sanitization

Acidic water combats or at least slows down several kinds of bacteria. It can thus be used to clean the various surfaces of the kitchen and bathroom. It can also be used to safely clean up pots and pans.

You can use acidic water around the cooking areas, and as an extra rinse for the various dishcloths and cleaning sponges. It cleans them efficiently and greatly reduces unwanted odors.

For Washing Vegetables

Acid water is potent in countering e-Coli bacteria, that’s why washing your vegetables with it is highly recommended. Doing an extra rinse with alkaline water gives better results.

For a Healing Bath

Adding around 3 gallons of acid water to your bath could speed up the recovery from an athlete’s foot condition, reduce the effects of chapped skin and promote its regeneration, limit hair loss, help in eliminating dandruff, treat acne, and clear out skin spots.

In Gardening

Watering your plants with acidic water usually revives them. It’s interesting to note that rainwater is also acidic.

You could also put some acidic water in your vase before arranging a freshly cut bunch of flowers inside it. This way the flowers will remain in full bloom for a longer time.

To Clean Glass

Spraying acidic water on your windows, mirrors, or even eyeglasses is a quick and easy way to make them spotlessly clean and super shiny. You can use it also for polishing your cutlery.

For Showering your Pets

Unlike many commercial cleaners, acid water isn’t toxic or unsafe to your pets, and it’ll keep their hair nicely sanitized.

A Different Opinion

There’s some controversy regarding the effectiveness of drinking and using water with a pH level other than 7. The available research is still not very conclusive about these matters, but there’s increasing enthusiasm in favor of alkaline and acidic water.

There’s a study conducted at Mayo Clinic that views regular drinking water as the better choice for general wellbeing.

The world health organization issued a report that advises against drinking water with low mineral content. This is concerned more with the traditional filtration systems that rid the water of almost all its minerals without replenishing them in any successive stages.

There’s also the issue of making the body too alkaline which is scientifically referred to as alkalosis. It’s a serious condition that causes nausea, vomiting, jittery hands, muscle twitching, and disorientation. It can also affect the calcium content and weaken the skeletal system.

Other studies are more in favor of using enhanced alkaline water as an antioxidant, or for alleviating the symptoms of diabetes, cholesterol, high blood pressure, and acid reflux.

Conclusion

Drinking enhanced purified water is certainly good for the human system, considering that our bodies are 70% water. The pollutants in our surroundings seep into everything we eat, drink or breath. It’s wise to try and purify whatever we can.

Luckily, drinking healthful water is easier now than ever before. Choosing the right device isn’t so easy though. Most of the ionizers on the market and in this review bring something extra to the table.

Having said that, I’d recommend using the Aqua Ionizer Deluxe 7.0. It is manufactured and tested according to the highest quality requirements, so we can be sure that it’s dependable and effective.

It offers a wide range of ionization options, it has a convenient smart design, it’s easy to install, and it comes at an affordable price.

The next runner up is certainly the ultra-high tech Pure Hydration NEXT GENERATION Water Ionizer, especially if you don’t need acidic water.

It employs a different concept in the ionization process. Their approach is natural and simple, but quite effective in producing alkaline water.

Its double filtration system eliminates more contaminants than any of the other ionizers. It’s also very versatile, and its design is super elegant and practical.

We hope this article has been helpful as you decide which water ionizer to buy.
