What is Ionized Water?

Before we dive into our buying considerations, it’s probably best if we first explain what ionized water means. Basically, ionized water is water that has passed through an ionizer machine.

A water ionizer contains plates made of platinum and titanium. These plates serve to exchange some of the titanium and platinum ions with the water. This process shifts the PH level of the water to be more alkaline, and also, the water is purified.

Consequently, we can conclude that ionized water can also be called artificially alkalized water. You can also refer to ionized water as electrolyzed reduced water because of its role in decreasing the harmful effects of oxidative stress on the human body. (More on the benefits of alkaline water soon!)

So what is the difference between alkaline water and normal water?

Now, you may be wondering: so, what makes alkaline water any different from regular water that you drink every day? Well, it’s all about the pH level of the water.

You see, the pH level of a substance refers to its degree of acidity or alkalinity. The pH scale goes from 0 to 14, where pH 0 is the highest acidity and pH 14 is the highest alkalinity. Substances with a pH level equal to 7.0 are said to be neutral.

This means that if a substance has a pH below 7.0 down to 0, it’s classified as acidic. For example, vinegar has pH 3 while the pH of lemon juice is around 2.

On the other hand, substances having a pH of more than 7.0 up to 14 are classified as alkaline. For example, the pH of baking soda is just over 8 and the pH of ammonia is about 11.

On the pH scale, normal tap water has a neutral pH of approximately 7. This can change due to chemicals or gases to shift the pH of the water to be more acidic (like rainwater) or alkaline (like chemically treated municipal water or hard water).

Typically, alkaline water has a distinct sweeter taste than regular tap water due to the difference in pH level, which also relates to varying levels of minerals such as calcium, potassium, sodium, and magnesium.

Moreover, to be considered alkaline, water must have a negative ORP (oxidation-reduction potential). This happens when the water has a lot of extra electrons that it can donate to electric-thieving active oxygen atoms. In this case, alkaline water can also be referred to as ‘Live Water’.

In standard drinking water, there are no extra electrons, and so, the water tends to have a positive ORP.

How do Water Ionizers Work?

Now that you know what alkaline ionized water is and how it differs from regular drinking water, it only makes sense that you understand more about the actual operation of a water ionizer.

Let’s start by saying that it may seem complicated at first, but it really isn’t all that difficult. So here’s what happens:

The water ionizer is connected to the kitchen water supply so that any time you want to drink, cook, or clean, you’ll get ionized water. Standard tap water goes inside the machine and leaves as alkaline ionized water.

The machine doesn’t add anything to your water, however, it does convert the bicarbonates in the tap water into hydrates, which are more alkaline materials.

How? Well, Tap water contains magnesium and calcium bicarbonates. The water ionizer separates the magnesium and calcium from the bicarbonate using platinum and titanium plates (electromagnetically-charged). The ionizer then produces two separate streams of water, one is alkaline and the other is acidic.

What are the Benefits of Alkaline Water?

According to The National Academies of Science, Engineering, and Medicine, women need to drink about 2.7 liters (91 ounces) of water every day to be adequately hydrated, while men should drink around 3.7 liters (125 ounces).

With such amounts of daily intake, did you ever stop to think about how the components of water can affect your well-being?

I mean, water already plays a critical role in every cell, tissue, and organ in your body, but just what kind of benefits does alkaline water offer when it comes to your overall health?

The following are some benefits that may be attributed to alkaline ionized water:

  • Support bone health – some research has been done to discover the effect of alkaline water on bone health. A 2009 study published in Bone found that alkaline water can lower bone resorption.

Bone resorption is the breakdown of bone cells to form new ones. Less bone resorption means more density, stronger bones, and a lower risk of osteoporosis.

  • Help with acid reflux – many people believe that drinking alkaline can help reduce acid reflux. Researchers are open to the possibility of drinking alkaline water as a supplement to other treatments of the reflux disease.

 

  • Detoxify the body – it also appears that alkaline water can help detoxify your body by flushing built-up toxins outside your systems. It may also be able to boost your energy levels and provide your body with useful minerals.

 

  • Replenish electrolyte – many people, especially those who regularly work out, swear by the ability of alkaline water to replenish electrolyte in the body, especially after intense workouts and physical labor.

 

  • Decrease blood pressure, blood sugar, and blood lipids – the effects of drinking alkaline on blood parameters were studied by a group of scientists in Shanghai.

They found the levels of blood pressure, blood sugar, and blood lipids had dropped significantly after 3 to 6 months of drinking alkaline ionized water. This suggests the positive effects of alkaline water on reducing the chances of diabetes and high blood pressure.

How to Choose the Best Water Ionizer?

When shopping for the best water ionizer, there are several factors that you should consider first before making a purchase.

These machines are quite sophisticated and complex, so they come with various features that aren’t necessarily present in all models. Here are the most important ones that you should definitely look for in your water ionizer:

pH Range

The main purpose of people investing in a water ionizer is to get ionized aka alkaline water. Whether or not the machine can efficiently do this depends on its capacity of changing the pH level of the water.

Water ionizer machines aren’t created equal in this aspect. Some models offer remarkably wider pH ranges than others, which affects the flexibility you get to work with.

It’s quite handy to have a machine that provides a decent pH range so you can take advantage of each band in certain use.

For example, acidic water with a lower pH is better suited for cleaning and disinfecting tasks. While more alkaline water is what’s considered safe and healthy for humans to drink and cook with. It’s up to you to decide if you need all the options.

ORP Range

As we mentioned above, ORP stands for oxidation-reduction potential, which indicates the capability of the water ionizer machine when it comes to decreasing the harmful effects of oxidation inside your body.

In theory, lower ORP values correspond to healthier water for you to drink. This means that a water ionizer machine with a lower ORP value will offer a higher capability.

Number of Plates

The plates in a water ionizer are the site of water conversion from acidic to alkaline. So you can conclude how crucial they are to the entire process.

If one machine has more plates than another, this means it’ll be able to turn over a greater quantity of water with a larger pH range and a better ORP value. In other words, more plates translate into more power.

However, more plates also demand more money and more energy. So not only will the initial price of the unit be higher, but it’ll also cost you extra in the long run.

Integrated Water Filter

Finally, a built-in water filter can really come in handy when you’re dealing with a water ionizer. This is because you’ll get alkaline water that’s also been purified, adding to its safety and benefits.

If you live somewhere with a well water supply, you may need to consider a unit with a more powerful filter to be able to handle the water pressure.

Keep in mind, however, that filters do require periodic replacement and maintenance, which adds up more costs over time.

Wrap Up

Choosing the best water ionizer can surely get confusing, especially with all the complicated specs and fancy features flying around. However, we’re confident that once you go through our buying guide, you’ll be able to find the perfect water ionizer for your needs from our top 5 list.

That being said, if you’re in the market for a reliable water ionizer that produces water at a wide pH range and an optimal ORP, then the Air Water Life Aqua-Ionizer Pro Deluxe 9.0 Alkaline Water Ionizer Machine should be right up your alley.

But if you’re on a budget and looking for an ionizer to provide all the necessary benefits without breaking the bank, then check out the Webetop Water Ionizer and Purifier Machine for a true bargain.
