Top 20 Water Ionizers Review 2021


Aqua Ionizer Deluxe 7.0Editor’s Choice

  • Number of plates: 7
  • pH levels: 5-11
  • Filter life: 6000 liters
  • Dimensions: 5.2 x 4.3 x 13 inches
  • Warranty: lifetime limited

Extra features: 7 water settings; ETL & RoHS certified

The Aqua Ionizer Deluxe 7.0 Alkaline Water Machine is one of the top rated alkaline water ionizers/machines. This model of water purifier has multiple water option settings, is self-cleaning and has a carbon filter that lasts for several hundred gallons. It is able to give you multiple settings for the level of alkaline and acidity you want it to filter out. I discovered that it comes with electroplate technology and FDA approved plastics. Hence, it is safe to use. This model works by first putting the water though a thorough cleansing process and then adjusting the pH levels. This is all automated and your selection of the needed pH levels is programmable. The ionic plates use electricity within the metal plates that causes the ions to charge or discharge. This process of cleaning water is an approved way to completely clean your drinking water yet leaves the good properties of the water intact. This small device that will fit on your kitchen counter or under the sink also has a self-cleaning cycle to keep your device clean and working well. One of the best features we love about the Aqua Ionizer Deluxe 7.0 is the excellent pre-filter. The filter targets the most important contaminants. It can handle a relatively decent amount of water and lasts for a long period. It also has impressive pH and ORP ranges. The pH ranges from 4.0 to 11.0 and can be adjusted. The ORP on the other hand ranges from +600 to -750 mv.

What stands out?

  • Self-cleaning helps reduce load of maintenance
  • Has seven different water options
  • The filter can be used for up to a year

What cons did we manage to find?

  • Installation is quite tricky

Aqua Ionizer DeluxeBest Value

  • Number of plates: 5
  • pH levels: 5-11
  • Filter life: 4000 liters
  • Dimensions: 16 x 13 x 9 inches
  • Warranty: 5 years

Extra features: active carbon water filter; self-cleans using reverse polarity and auto-plate washing

Air Water Life has a reputation of manufacturing high quality products, and the Aqua Ionizer Deluxe water ionizer is no exception. Water ionizers often come at a high price, but fortunately, this particular model is a budget option. Despite the low price, it filters and ionizes your water. Due to the ionization, the water reportedly has antioxidant properties, which some have linked to improved digestion and balanced blood pressure. These antioxidants also allow you to sleep better and have a more energetic day.

Weighing in at 8 lbs., and standing 13” tall, the Aqua Ionizer Deluxe 5.0 is a compact unit that fits easily on your kitchen counter. Size-wise it’s about average for a water ionizer of this type.

It uses 5 titanium coated plates that cover an 81.8” surface area. This ensures as much water as possible passing through the system when it undergoes electrolysis. The 5 plates give an antioxidant potential between the ranges of -600 and +600 ORP. The negative value is the one of most importance and represents the level of anti-oxidation that the water possesses. Anti-oxidizing water is thought to have many health benefits and the more negative this value is the better. To put that in perspective, the top bracket ionizers tend to achieve around about -1000 ORP. However, they cost at least 3 times as much as this model and in some cases more than 6 times as much.

These plates produce water that ranges in pH from 4.5 to 11. The water is available in 7 choices that are picked at the press of a button. There are 4 alkaline varieties, a neutral pH, and 2 acidic options. The acidic water is great for disinfecting and cleaning. The ORP value of the water can be chosen throughout the pH range.

Aside from these features, it comes with a self-cleaning feature that ensures that the plates don’t become coated with calcium which is inimical to their effectiveness.

All of these features come at a low price.

Why did it make our list?

  • Excellent value for the price
  • Built-in water filter
  • Self-cleaning feature

What is not ideal about it?

  • Limited pH range
  • Low ORP range

The design of this water ionizer is simple and clean. It doesn’t have too many buttons or readings on the front display which give it a nice clean look. The unit has a built-in filtration system to remove sediments and other impurities with activated carbon.

It ionizes water to approximately 8.5-9.5 pH, which is an impressive value. The ORP number is decent as well, although many of the options on this list have better ORP values. It has an ORP range of -150 to –350, which is better than the ORP number of an electric ionizer filter. With ORP, the lower the negative value, the better ionized the water is.

As pointed out earlier, I liked the sleek, simple, stylish, and portable design of this model. Made in the USA, it is made of high-quality materials and has been tested by standard organizations to reach the right specifications for safety and performance.

It doesn’t require any electricity to function. All you have to do is to hook it up to the water system and drink. The filter works for six months if you consume 2 gallons of water every day.

Furthermore, the alkaline water produced by this machine will be able to detoxify the body, increase your energy levels, and ensure proper hydration for the body.

One of the most impressive features of this model is the advanced electroplate technology. The 5 titanium plates that are coated with platinum will ensure efficiency for numerous years. In fact, this particular model has been assembled in Japan and the plates have been manually placed to ensure efficiency. It comes with an activated Carbon Filter that will remove organic matter, residual chlorine, odors, and harmful contaminants Additionally, there is an automatic cleaning feature that helps to prevent build-up. An interesting feature is the Voice Reminder. With this feature, you will always know when to change the filter as you will be reminded when the time comes near.

You can purchase with confidence as we have thoroughly tested this model.  What stands out about this model is the fact that the filter will last for at least 6 months depending on how frequently you use it. It’s important to mention that even though it requires for the filter to be changed, it’s not expensive at all. Hence, if you’re on a budget, this is a great model to consider.

Aqua Ionizer Deluxe 9.0Best pH Levels

  • Number of plates: 9
  • pH levels: 3.0-11.5
  • Filter life: 4000 liters
  • Dimensions: 6 x 12.4 x 8.7 inches
  • Warranty: lifetime-limited

Extra features: 7 water settings; ETL & RoHS certified

Earlier, I reviewed the Aqua Ionizer Deluxe 7.0 and Deluxe. Well, the Aqua Ionizer Deluxe 9.0 is the big brother of the Ionizer Deluxe 7.0 and Deluxe from the same company. It claims to produce water with a pH level between 3 and 11.5, depending on the settings you choose. This model is the ninth generation of the Aqua Ionizer Deluxe line-up, and it has a few more advanced features than its predecessors.

The Aqua Ionizer Deluxe 9.0 may be a great option for you if you’re looking to detox your body and create a more alkaline environment in your body. The Aqua Ionizer Deluxe 9.0 gives you more control over the pH level of your tap water. Right next to the alkaline button in the center of the control panel is an up and down arrow, which allows you to raise or lower the water’s pH level. This feature is helpful because it allows you to make pH adjustments according to your needs, rather than giving you an “all or nothing” system. If you’re making coffee, you may want to use more alkaline water. But if you’re cleaning, you may not care about using water with a lower pH level.

The seven water settings ties into the customizable pH levels feature. Before you start dispensing water, you can choose one of the following settings: Cooking, brewed coffee/tea, daily drinking, initial drinking, purified water, cosmetic, and household cleaning

The lower down on the list you go, the more acidic the water. The household cleaning setting, for example, will have the lowest pH level, whereas the cooking setting will have the highest. Having multiple settings helps make it easier to choose the right pH level for your needs (I like that because it takes the guesswork out of the equation).

Aside from these, other features I liked during testing include the high, 4000 liter limit on the filter, and the high pH and antioxidant potential.

Why are we impressed?

  • Has multiple water settings
  • Maximum pH of 11.5
  • Advanced filtration system
  • Environmentally friendly

What negatives must you be aware of?

  • Not easy to master
  • Complex installation
  • Number of plates: 11
  • pH levels: 3-11
  • Filter life: 8000 liters
  • Dimensions: 13 x 9.6 x 5.1 inches
  • Warranty: 5 years

Extra features: 7 water settings; large size Titanium with Platinum coating plates, applied with Japan imported IONIC MEMBRANE

This model comes with advanced electroplate technology. It features 11 large size Titanium with Platinum coating plates, which are applied with Japan imported ionic membrane, thus providing higher efficiency electrolysis and longer working time.

During testing, we observed that it comes with an internal replaceable activated carbon water filter which efficiently removes the bad taste, odors, organic matter, residual chorine and other harmful substances in the water. It is very efficient and offers relatively long usage life of absorption. The hi-tech filter purifies over 8000L and lasts up to a year. An interesting feature is the Self-Cleaning Function. The machine cleans itself by reversing polarity after each use and auto-plate washing itself when the flow rate is lower than 0.8L/M. You also can reset it according to the water quality. Installation is quite simple and straightforward. The machine works safe with 110V~220V, can be easily set on the countertop or mounted to the wall near the faucet in kitchen or utility room.

With a stainless steel design and an easy to read display, the Bawell Platinum Alkaline Water Ionizer is one of the more stylish countertop water ionizers. The touch screen LCD is one of the favourite features that we liked. With the eight pre-programmed setting, it’s very easy to use. Another favourite feature is the fast water flow rate at one gallon every 30 seconds. To use this ionizer, you will want to have a fair amount of counter space either to the side or back of the faucet. That said, the unit should fit fine in most kitchens. It is incredibly convenient that you can choose to attach it either to the water line itself or your faucet head. And since the universal adaptor makes it compatible with most faucet heads, you should not need to worry about replacing yours.

The Platinum Alkaline Water Ionizer by Bawell is made out of BPA-free food-grade plastics which have received the approval of the FDA, so it is a healthy device to run your water through. The filtration technology will cleanse your water of harmful microbes and remove unwanted minerals (great if you are trying to fix a hard water problem). Additionally, the huge number of pre-programmed settings (8 at each power level) makes it a breeze to get your water as alkaline or acidic as you want it.

We should note this is the top of the line model offered by Bawell. All these feature, along with the dual filtration system, make the Bawell Alkaline Water Ionizer machine one of the best water ionizers on the market today.

What makes it stand out?

  • Nice range of alkaline and acidic settings
  • The water tastes great
  • Great customer service

Which disadvantages must you keep in mind?

  • Installation instructions are rather vague
  • Number of plates: 5
  • pH levels: 3.5-10.5
  • Filter life: 6000 liters
  • Dimensions: 15 x 6.6 x 6.5 inches
  • Warranty: not specified

Extra features: 7 water settings; auto self-cleaning; Titanium with Platinum coating plates, applied with Japan imported IONIC MEMBRANE

There are several reasons why the Webetop Water Ionizer and Water Purifier makes our list of the best water ionizers. For one, it boasts of multiple titanium plates and a large filter that adjusts the pH level of the water for quick fill-ups and reduces bacteria and heavy metals, creating fresh, clean, tasty water. There is a large color screen that makes it easy to choose your preferred water setting. Additionally, it doesn’t take plenty of time to set it up. The ease of installation is quite refreshing; especially when you consider that several of the options we have do not offer this same ease.

Inside of the Webetop Water Ionizer, there are five electroplates made of titanium, which is a strong and erosion-resistant material. Since these plates are coated in platinum, they are able to start the electrolysis process instantly, so you don’t have to wait minutes on end for a glass of water. The Webetop Water Ionizer features five alkaline water settings for drinking, cooking and disinfecting as well as two acidic water settings, which are ideal for skin care. Plus, there is purified water setting you can choose when you need to make infant formula.

Another nice reason why this ionizer is so highly rated is its long-lasting filtration. It helps to eliminate nasty tastes and bad odors from your water. Because of the carbon filter, fluoride and other inimical heavy metals are eliminated from the water. Since the filter can last through 1,585 gallons, you only have to replace it once per year. With the appliance’s reverse polarity system, it cleans the plates every 7.9 gallons to keep calcium build-up at bay.

The color LCD allows you to see information like the water’s pH level, the flow rate, temperature, filter life, and cleaning status. You will also likely love the seven water settings that you can choose from.

What makes it stand out?

  • Reduced ORP levels
  • Self-cleaning function
  • Versatile

Which disadvantages must you keep in mind?

  • Has just one filter and no pre-filters

Pure Hydration Next GenerationBest Battery-Run Ionizer

  • Number of plates: none, mineralization using natural earth elements
  • pH levels: 9-9.5
  • Filter life: 2300 liters
  • Dimensions: 8 x 14 x 14 inches
  • Warranty: 15 days – filters, 2 years – all components

Extra features: germ-free touchless on/off infrared sensor; non-electric; countertop or under-counter configuration

There are many reasons why you should strongly consider the Pure Hydration as your next water ionizer. Firstly, it is touch free. The Pure Hydration turns on and off with the wave of a hand using infrared sensors. Getting a cup of water is quick, easy, and hands free for those hectic moments. Another advantage of getting this ionizer is that you can choose not to install in on a countertop.  While it is possible to install it under the sink by connecting it to the faucet line, its primary use is as a countertop dispenser, similar to a traditional water filter like a Brita system. It also comes with a great filter system. The carbon filter works up to .02 microns for a very thorough filtering, and the alkalizing process this unit uses naturally reintroduces minerals to the water that would otherwise be lost in filtering. Most products on the market, including some on this list, cost quite a lot of money. However, the Pure Hydration costs close to a third of the cost of most products on this list, making it an excellent budget buy. Despite all these advantages, there are some things we didn’t like about it. Alkaline water produced via the chemical process (passing water through a filter designed to add alkaline minerals to the water) is a whole different process than the electrolyzing process the majority of other models use, and may as well be a different product entirely. While not necessarily bad, it’s not what you might necessarily be looking for when you’re thinking of purchasing a unit. As a plus though, it works without electricity.

Because of the factors above, the Pure Hydration only produces water from 9 to 9.5 pH, making it one of the smallest ranges available.

What are our favorite features?

  • Touch free
  • Doesn’t require installation
  • Has an excellent filter

What could be better?

  • Low pH range

IntelGadgets IONtech IT-757Best Activated Carbon Filter

  • Number of plates: 5
  • pH levels: 4.5-11
  • Filter life: 4732 liters
  • Dimensions: 12.2 x 8.7 x 4.9 inches
  • Warranty: 2 years

Extra features: 7 pH levels which include 4 alkaline levels, 1 purified level, and 2 acidic levels; automatic cleaning cycle; hi-tech Platinum- Titanium electrolysis alloy plates with precise ceramic ionic membranes

I personally really like the attractive design of the LCD display featured on the 757. The part I love most is all the different values it displays compared to other units. On the green LCD display, you can see the current pH level, water flow rate, ORP, and remaining filter life. I haven’t seen other units that offer all that valuable information at a quick glance at this price. This model uses five premium platinum-coated titanium plates to ionize the water. While you might feel that five is rather small, it is important to note that other ionizers with 7 or 9 plates typically cost more.

I observed that the 757 uses one high-efficiency ACF-1 activated carbon filter that can filter 1250 gallons before needing to be changed. This filter should last most people at least 6 months or up to a year at about 3 gallons per day. You can be confident that the filter removes harmful substances including chlorine, pesticides, and dirt.

You can make water in a pH range of 4.5-11 with the 757. A notable feature is that the maximum ORP (Oxidation Reduction Potential) value of this model is -850mV which is quite high for this price range. The lower the ORP, the more anti-aging antioxidant benefits you get in every glass.

I enjoyed installing the unit as it can be done quickly and fairly easily. The unit can be installed on the countertop or under the sink. The extra-long hose makes pouring water easier.

Another cool feature is the plus and minus buttons that let you choose exactly which pH you prefer. Other units don’t offer this option. There’s a safety feature that makes sure you and your family don’t accidentally drink acidic water.

As with most of the top ionizers on the market, it comes with seven water settings to choose from: 4 alkaline, 2 acidic, and 1 purified water setting. The self-cleaning feature on the 757 is super smart. Each time you finish using it, it does a quick 10-second chamber cleaning. Then, each time 7.9 gallons have gone through it, it does a full 2-minute cleaning with music to let you know when it’s finished.

Unlike the other units I’ve reviewed, the 757 works with both 110v and 220v, which is good news for international buyers. The IONtech 757 comes with a 2-year warranty.

Why are we impressed?

  • Activated carbon filter eliminates harmful chemicals and bacteria.
  • Consistent performance

What negatives must you be aware of?

  • Filter needs to be changed frequently

The AlkaDrops LED Water Ionizer Purifier Machine is an elegantly designed, yet cheap water ionizer. Due to its low price, it is more accessible to a wider range of people on the market. Aside from the low price, it comes with several remarkable features that make it one of our favorite options on the market.

It comes with a carbo filter that aide it in eliminating impurities present in your water. Hence, you can drink tap water without fear of ingesting harmful things that can put your health at risk. Additionally, it comes with platinum coated titanium plates that ensure that the electrolysis process is successful each time it occurs.

The AlkaDrops comes with seven water settings, a feat that is impressive for an ionizer of this price and manufacturer. These settings include: one non-ionized purified water option with a pH level of 7.0, two ionized acidic water options with pH ranging from 3.5 to 6.5, and four ionized alkaline water options ranging from 7.5 to 10.5.

It comes with a carbon filter as well. This filter needs to be replaced after 6 months of use, or after filtering about 6000 liters of water. Hence, when compared with some other models on this list, the filter isn’t as durable.

The self-cleaning feature of the water ionizer helps to clean the machine automatically. Therefore, it helps you to get rid of scaling that could possibly damage the ionizer. I especially like the neat LCD display that allows you to check or select settings that affect the flow rate, the pH level, temperature, or the ORP level.

What are our favorite features?

  • Removes up to 98 percent of water
  • Offers you four alkaline level and two acidic level to choose from
  • Come at an affordable price

What could be better?

  • Filter needs to be changed every 6 months

Ionization, which is an important reason of getting the IT-580, is excellent. The water ionizer can change the alkalinity of the water from 4.5 to 11.0 pH. With this efficient water ionizer, you can transform typical tap water into alkaline water that contains antioxidants and healthy minerals that help the body become more healthy and energized.

Another plus for this machine is its filtration system that removes large amounts of contaminants from the water. Nowadays, water ionizers often included an activated carbon filter which is majorly responsible for removing large particles of dirt, rust but also get rid of harmful contaminants such as chlorine and water impurities as well. There’s, however, a small drawback related to the activated carbon filter. In order to make sure that the IONtech IT-580 delivers optimal results for the years to come, you need to change the filters after several years.

If you seek an alkaline machine or water ionizer that delivers top-notch performance that rivals expensive models, but itself costs just a fraction of the cost, then you should pay attention to the M9 Next Generation Water Ionizer. It gives you clean, worry-free water, while offering you an unlimited warranty that include labor and parts if for some reason your machine gets defective.

Here are some of the reasons why I love this ionizer. Firstly, it comes with an extraordinary filtration system. Also, it is very easy to manage and is user friendly; anyone who is using this for the first time will be able to understand how the filter works. There will be no need for you to replace the filters with tools, because it has extra leak protection that is secure enough. It has two rubber O-rings that keep the filters in place, rather than one filter thread that can come off easily and can become unstable.

To ensure that the water coming in leave as pure as possible, it also has a pre customized filter system that gives you and your family pure drinking water. The filter system helps to keep out all the toxins that come from tap water. It has the ability to take out contaminants like chromium, copper, lead, mercury, and other impurities that can be bad for the health. It has free water reports for quality – with this machine, you get to examine and analyse the results of the water that you get from the tap, and identify the contaminants to get better drinking water. After you have found out the results you can now customize the filtration for the alkaline machine so that it gives you better tasting water without the contaminants.

It has UV light technology that will help protect your family from all the invisible water threats found in tap water while keeping all the additives and harmful chemicals away. This UV light is EPA approved, and will further eliminate any harmful bacteria, viruses and microorganisms.

It costs less than $70, which is an incredibly low price when compared with others on this list. During my testing, I observed that the model does work and produces alkaline water that is consistent with the readings on the display. However, since it only has 5 plates instead of 7 or more, it won’t produce the alkaline water as quickly. The plates also have a mesh, slotted design, rather than being solid. This is helpful in bringing down the cost since platinum titanium is very expensive. But the slotted design can also be more difficult to clean and be a little less durable. It’s a trade-off between the price and efficiency of design. However, even with these drawbacks, this model of the New Cell will still produce good alkaline water. It may just be at a slower rate as some of the more expensive models. One other consideration is the replacement filter. The filter on this model needs to be replaced a little sooner than some other models after just 3,000 litres.

Things to Consider

Using a water ionizer is a good and healthy choice. However, we admit that it can be challenging choosing the right one. In selecting the twenty product above, we considered several essential factors. In this buying guide, we will discuss these factors and why they are important as you choose the best water ionizer.

What is a water ionizer?

20 Best Water Ionizers - Your Healthy Lifestyle

It is an open secret that tap water isn’t as safe as it is believed to be. Although the chances of getting sick due to tap water are slim, many folks are exposed to water that violates health guidelines. Hence, one can never be too careful with the water one drinks. It would be great to have fresh, delicious, and filtered water right out of the tap, wouldn’t it? Well, water ionizers are here to help!

While some in the scientific community isn’t completely sold on the health claims, there is a great deal of study-based evidence to suggest that alkaline water produced by ionization has life-enhancing benefits.

We will consider what a water ionizer is as well as how millions around the globe have enjoyed many benefits from it, including disease prevention, improved energy and vitality, weight loss, anti-aging, digestive relief, and much more.

A water ionizer, as discussed and reviewed in this article, is also referred to as an alkaline ionizer. It is an appliance that uses electrolysis to provide alkaline water by increasing the pH of the water that comes for the tap.

In simple terms, this appliance makes the water from your tap more alkaline by dividing the water into its acidic and alkaline parts. After splitting it into two parts, it is the alkaline (healthier) part that is then delivered to you from the tap.

This water is purified, filtered, high-pH water. These appliances were a craze in Japan and other far-eastern countries long before catching on in the US and Europe. Now they can be found all over the world as people look for ways to avoid unhealthy water.

Benefits of Alkaline Water

It should be noted that these claims are not completely accepted in the mainstream scientific world and have not been evaluated by government authorities. However, this doesn’t mean that some of them aren’t true. People from all over the world have attested to the health benefits that they derive from drinking ionized water. Here are some of these benefits:

  • Better Hydration: The electronic process involved in producing the water breaks down groups of molecules into smaller clusters, making them easier for cells to absorb. Thus, you might be drinking the same amount of water as usual, but it hydrates your body better.
  • Antioxidants: The abundance of free electrons is a treasure trove of antioxidants for the body that help neutralize free radicals. And these antioxidants are responsible for many nice health benefits.
  • Greater Balance: The body is naturally on the alkaline side, so if it is too acidic you may feel lethargic or even worse. Supplementation of alkaline via ionized water may promote balance in the body. This leads to a number of life-enhancing benefits that people across the world now swear by.

What are the health benefits of a water ionizer?

20 Best Water Ionizers - Your Healthy Lifestyle

If you often feel tired or lethargic, or you are sick and have aches all over your body, a water ionizer might just be what you need to get you back on your feet. Here are some of the advantages or benefits of having a home water ionizer.

  • Never Worry About Drinking Water Again:  Public water systems are not nearly as reliable as we had assumed, and people around the globe spend trillions of dollars on bottled water every year! With a water ionizer, you’ll never have to worry about water quality again. Each time you fill up a glass or cook for your family, you can be 100% sure that it’s safe and clean.
  • Feel Healthier. Feel Better: Are you always tired? Is each day a struggle? Whether or not the controversial “acidosis” condition exists, what we do know is that hydrating with alkaline water allows you to retain more fluid throughout the day. There’s a reason that athletes are recommended to drink it. With more energy at your cells’ disposal, you’ll feel better and more energetic throughout the day.
  • Cut Weight Faster: With healthier water and more energy, you’ll find it easier than ever to actually get up and do that workout you’ve been promising yourself you’d do.
  • Supercharge Your Health: Water from an ionizer is rich in minerals that your tap water doesn’t normally have. Calcium, potassium, and magnesium are all vital to human health. Now you’ll have a constant stream of healthy minerals all day, every day
  • Feel Younger and Fight off Sickness: Free radicals are particles in your body that damage cells because they don’t have an electron to partner with. They are proven to do damage to cells and DNA, causing faster aging and damage to the immune system. As a rich source of antioxidants, alkaline water from your ionizer helps free radicals partner up with electrons and prevents this damage, causing you to look and feel younger.
  • The Best Tasting Water You’ve Ever Had: This is definitely a subjective opinion, but it’s true that tap water (especially well water) always tastes a bit off. Depending on where you are from, your water is most likely too acidic. Even if it isn’t, it still doesn’t go through a purification process. That’s why so many people are buying bottled water now. An ionizer will produce delicious, purified water that is actually delicious to drink. You won’t need any of those sugary drinks anymore (OK, every once in a while is still fine).
  • Cancer Prevention Benefits: The most commonly cited benefit of water ionizers and drinking ionized water is the anti-cancer benefit the water is thought to deliver to the body. According to many water ionizer proponents and retailers, ionized water has strong antioxidant properties. An antioxidant is a compound that is believed to prevent free radical damage to cells and their DNA by neutralizing and eliminating these free radicals and keeping them from causing the cellular disruptions that can lead to cancer. According to Ion Life, the hydroxyl ions in ionized water can neutralize free radicals in the same way that other, acknowledged antioxidants like Vitamin A and C can. And, as Watershed points out, once the hydroxyl ion gets rid of these free radicals with its extra electrons, the result is an oxygen molecule, an essential element for proper body functions.
  • Cardiovascular System Benefits: Alkaline Water Plus reports recent research has indicated that heart disease–as well as the overall health of the veins and arteries in the entire cardiovascular system–is strongly correlated with oxidative damage: in other words, the free radicals produced by normal oxygen metabolism can cause damage to various parts of the cardiovascular system, making heart disease more likely. Since water ionizers produce water that is believed by many to act as a preventative measure against free radical damage, supporters advocate their use for this reason as well.
  • Skin Benefits: Water ionizers are also thought to produce water that is much more beneficial to skin than regular tap water if you use it regularly to wash with. Ionized water is said to confer its antioxidant effects to skin, causing it to appear younger and to remove fine wrinkles, as well as decreasing the amount of skin bacteria present so that acne breakouts are less common. Ionized water reportedly acts as strong detoxifying agent; this is thought to benefit the internal organs as well as the appearance and health of the skin.

Features to consider while choosing a water ionizer

Before investing into the new water ionizer it is advisable that you keep in mind some features, which are the MUST HAVE in each of such devices.

Effective flow rate

Before the water enters your glass, the water ionizers require some time to properly filter and convert it from the regular tap water to alkaline water. Some of the water is converted to acidic water, as the water ionizer splits the tap water into acidic and alkaline. Therefore, you can expect that the alkaline water flow rate is less than the normal tap water flow.

Hence, you should consider how quickly the ionizer converts the water into alkaline water. The more plates there are in the ionizer, the faster the water flow rate will be. The best water ionizers on the market usually have redesigned electrolysis chambers that will reduce the amount of wasted water, thus resulting in as much as 40% increased flow rate.

pH levels

20 Best Water Ionizers - Your Healthy Lifestyle

You might have heard of pH levels. Well, what are they? What is pH and why does it matter so much?

Let’s have a quick chemistry lesson.

The pH (potential hydrogen) scale is a measurement of the acidity of a liquid. This scale ranges from 1-14, with the lower numbers indicating more acidity and the higher numbers showing alkalinity. As you have noticed among the models on our list Bawell Platinum Alkaline Water Ionizer Machine and Tyent UCE-11 Under Counter Water Ionizer feature the largest scale of pH 2-12. Examples of acidic liquids include black coffee and lemon juice. Baking soda, on the other hand, is alkaline as it registers above 7 on the scale. Water, which is essential for life, is neutral.

The type of water that is great for drinking should be slightly alkaline, since the body itself is acidic.

In choosing a water ionizer, you should be concerned about the machine’s ability to produce alkaline water.  As you’ve seen in our reviews, depending on the machine, some deliver quite a significant pH range, giving you flexibility and freedom in this respect.

If you’re wondering why this even matters, here is why. Each specific band is designated for particular utilization. For example, water whose pH level is low is suitable for cleaning and disinfecting. On the other hand, mildly alkaline water is healthy for us to drink on a daily basis. On top of that, alkaline water is suitable for cooking.

Of course, it’s entirely up to you if you need all these options. You should determine how you plan on using the machine and afterward make a decision accordingly.

ORP levels

ORP (Oxygen Reduction Potential), is a measurement of the number of electrons stored in the water. This feature is one of the main benefits of using an alkaline water ionizer.

Oxidation is the natural process that turns an apple brown, for instance. At the same time, it is the process that determines rust to appear. This is facilitated by taking out electrons. The same happens inside the human body: oxidation damages the cells, the DNA, the proteins, so on and so forth. The substance that takes the electrons is known as a free radical.

This is where antioxidant foods come in – these aim at protecting the body from the effects of the free radicals. The same principle applies to ionized water, which is believed to have the same effect, according to many researchers. That’s because the water restricts the free radicals’ capabilities of attacking your body, therefore, making it more vulnerable and susceptible to disease.

If your water has a high negative ORP number, it is more efficient in reducing the free radicals that cause cell damage and speed up the aging process.

Therefore, in choosing a water ionizer, ensure that it produces water with a high negative ORP number. The lower the ORP value, the better the water ionizer.

Plates and number of plates

While discussing the flow rate of the water ionizer, we briefly talked about the effect of the plates. Plates are an essential part of the ionizer and contribute immensely to the overall functioning of the machine.

The plats are important because they come in direct contact with the water. Hence, it is important to know the material your plates are made of. The material should be safe, and should imbue a high level of efficacy as well.

As you search for the best water ionizer, you should keep in mind that in most cases, the higher the number of plates a unit has the better. That’s because this translates into more power. Basically, a unit equipped with more plates is capable of producing water whose pH range is larger, and whose ORP is much better (we’ve discussed pH and ORP earlier).

Usually, the more affordable models come with 5 plates, whereas the pricier models incorporate 11 plates, such as Tyent UCE-11 Under Counter Water Ionizer, AQUALKA Water Ionizer & Purifier Machine PH 3.5-10.5 and iRayer Alkaline Water Ionizer. However, it’s also worth noting that, if the unit has more plates, it will consume more power; not to mention that it will be more expensive.

Filter and filter life

20 Best Water Ionizers - Your Healthy Lifestyle

Another important feature to keep in mind is the filter and filter life of your water ionizer. The majority of the work of the ionizer is carried out by the filter, hence, you should ensure that it is in the best shape possible.

If you are using a well water supply, for example, it would be wise to choose a water ionizer that has a powerful filter as it will be able to better cope with any water pressure. You should also consider the price and durability. Filters do not last forever. Thus, you will have to replace the filter after sometime. With that in mind, consider the maintenance cost of changing, cleaning, or replacing the filter. In most cases, the filter will last for six months to up to a year. However, this is largely dependent on how contaminated the water is and the amount of water filtered. It also depends on the manufacturer. But the overall longest filter life is featured by AlkaDrops Water Purifier Machine Water Ionizer, Rhorawill Alkaline Water Ionizer Machine and Chanson MIRACLE Counter Top Alkaline Water Ionizer.

Water pressure

The water pressure differs from one place to another; hence you need to know how flexible the water ionizer that you choose is. If the ionizer only works at a particular water pressure level, then you might have problems as with other water systems that do not supply water at a specific pressure all the time. If the water pressure is high, the water will pass through the ionizing chamber very quickly, thus it will have less time to be purified. The longer it stays in the chamber, the better the purification.


If you have a small kitchen or space, then it would be prudent to buy a water ionizer with compact, portable dimensions. That way, you’ll be able to place it where you desire without worry about space. And probably the best portable option is NewCell Flow Water Ionizer.


Most water ionizers on the market are rather expensive and are significant investments. An ionizer isn’t a device you buy every other month. Hence, it should come with the assurance from the manufacturer. A lengthy warranty offers you peace of mind, especially as you are buying something as expensive as a water ionizer, like it is by M9 Next Generation Under Counter Water Life Ionizer or Aqua Ionizer Deluxe 7.0.

Extra features

One important feature to look out for is the certification that accompanies the water ionizer. Here are some of the important certifications the ionizer should have:

    • Canadian Standards Association (CSA)
    • European Conformity (CE)
    • Good Manufacturing Practice (GMP)
    • International Organization for Standardization (ISO)
    • American National Standards Institute (ANSI)
    • Price

      Since ionizers come in a wide range of prices, you should choose one that doesn’t eat too deep into your funds, and yet will deliver excellent performance. There are budget-level water ionizers on the market, and you can find some of them in the product review above. While they might lack some of the fancy features of their more expensive counterparts, they deliver where it truly matters: water quality.


Yes, you can. However, the ease of installation depends on the model of the water ionizer. Some ionizers come with installation guides that are straightforward and simple to follow, while others are difficult to install. If you find out that it is difficult for you, do not hesitate to engage the services of a professional. Your ionizer might be too expensive to be a DIY project.

They are manufactured from all over the globe, but a large number are made from Asian countries and from the United States.

It depends on how much energy you want to save. If you want to have ionized water available whenever you need it, then you can let it run all day. However, if you are willing to wait for some minutes every time before you use ionized water, then you can opt to switch it on only when you require its services.

It is safe to drink ionized or alkaline water. That’s because it includes natural minerals that your body can benefit from. Nonetheless, you should continually check the mineral levels inside the water, to ensure that what you’re drinking is good for you.

Our Verdict

Choosing the best water ionizers on the market is not an easy thing to do. However, by reading reviews such as this post, and considering the buying guides, you can make a right buying decision. From our observations and testing, we highly recommend our top pick, the Aqua Ionizer Deluxe 7.0. It comes with several water options you can choose from as well as a range of plates. It also comes in a small and compact design, which is great for folks that don’t have plenty of space in their home. The second one most popular model among customers Aqua Ionizer Deluxe offers the excellent value for the price, built-in water filter and a self-cleaning feature and allows to be easily fitted on your kitchen counter. But if money is an issue, then we recommend the NewCell Flow Water Ionizer. This model is one of the most budget-friendly options on the market, and considering the sleek, simple, stylish, and portable design of this model and the fact that it doesn’t run on the electricity but has ORP range of -150 to –350, which is better than the ORP number of an electric ionizer filter, it is one of the best solutions for ones who love to travel.

We hope that this in-depth review and guide will assist you in selecting the best water ionizers on the market.
