Best Water Ionizer: Reviews in 2021
Worried that your tap water contains thousands of contaminants that could cause disease? Feeling like tap water is making you sick? Don’t want to drink unpurified water anymore?
The answer is the best water ionizer. Do you want to know what it does?
Simple, it takes all the impurities like phenols, chlorine, sediment, odor, organic waste, taste, and bacteria out.
Then, the machine uses platinum plates to start the process of electrolysis, which separates the alkaline properties from the acidic ones.
The alkaline properties make the alkaline water – which is the purified version that water ionizers produce.
But of course, you will need to pick the right ionizer if you want to get these benefits. Otherwise, you may end up with the same tap water as always.
For that, we decided to review some of the best models out there and bring them to you. And we also found a buying guide so you could pick the right model accordingly.

Why Should You Get A Water Ionizer?
Getting a water ionizer will change the way you use tap water. And this happens due to a few main benefits such as:
Less Digestive Problems
Once the water has gone through the purifying process, it is cleaner & healthier. This prevents most digestive issues that some bacteria and other impurities from tap water may cause.
Restores pH Balance
When your body gets too acidic due to the properties of tap water and most of the food you eat – then your pH balance changes. This causes all kinds of conditions from constant diseases, bad body odor, joint pain, and more. With alkaline water, you can restore your pH balance and prevent all that.
Water comes in clusters of molecules. These clusters are what the body absorbs. Also, the more particles a cluster contains, the harder it is to absorb the water.
That’s why tap water does not hydrate as well as it should, as every water cluster contains about 15 molecules.
In contrast, ionized water clusters contain up to 8 molecules. That makes it way easier to absorb, which helps with hydration.
Alkaline water contains more antioxidants than regular tap water filled with acidic properties. This helps to boost your metabolism and make your skin look better over time.
It is pretty common for people drinking alkaline water to experience a better taste. After taking most of the impurities & acidic properties out, the water gets a purer taste.

Best Water Ionizer Machine Buying Guide: Things to Consider!
If you’re looking for the best alkaline water machine possible, then you’ll need to consider the right factors. Here are some of them:
First and foremost – consider the pH range of the machine.
This will tell you how well the ionizer can bring the alkaline levels of the water to healthy levels. But what you’re looking for is not a specific number – but two.
That means you want a machine that can work with the broadest range of pH possible. If it can handle pH levels as low as 1 pH and can bring it at about 10 pH or so – then that’s an excellent machine.
But if it can bring the pH levels even higher than 10 – then that’s an exceptional machine.
For example, pH levels at about 14 mean the water is super clean & alkaline. That brings a unique level of purity that you can enjoy to the max, giving the extra antioxidants and preventing the water from causing any acidic-related issue.
For us, the perfect pH range would be 3 pH to 12 or 13 pH. If you can get a machine with that kind of pH range, then you’ll have an excellent ionizer.
Similarly, to pH, you want an ionizer that can solve the ORP or oxidation level from the water.
Here, you’re not looking precisely for a range, but for the lowest level of oxidation possible.
The ORP is measured in mV. High mV levels such as +600 or around mean the water is highly oxidized and may contain tons of free radicals that damage your body. In contrast, low mV levels at about -600 mV will get rid of the free radicals and make the water cleaner & less oxidized.
That’s why you should always look for ionizers that can bring the oxidation level as low as -600 or even less if possible. And if it can handle highly oxidized water at about +600 or +700 – then that would be even better.
The whole focus should be on looking for the lowest ORP value possible. But make sure to consider the high range as well, it will often tell you how well the machine can fix the water.
Number of Plates
All ionizers come with platinum or titanium plates. These plates are the ones that produce the electrolysis, or the process that gets rid of acidity on the water.
The number of plates makes a huge factor because this will tell you how capable the machine can be. And this happens because the more plates it has, the better it will work – presumably.
For us, it’s all about the right numbers. You won’t need more than 10 plates in an ionizer to make it work correctly. In fact, the most effective models offer between 6, 7, or 8 plates in total. So you won’t need more than that if you want proper ionizing.
Still, make sure the machine has at least 5 plates. That will be enough to get your water ionized without problems.
Another super important feature that many people tend to overlook is the filter.
This is super necessary because a natural water ionizer does not only reduce acidity and oxidation levels, it also cleans the water from impurities like chlorine, germs, bacteria, sediment, and more.
That’s why we recommend getting the best water filter possible, something that can handle as many gallons or filters of water per charge.
Usually, filters can handle between 1000 and 1500 gallons of water (or about 4000 to 6000 liters). That’s enough to handle an entire year of water flow in a kitchen sink, for example.
Once the filter has processed enough water, then it needs to be replaced. That’s why we recommend getting as many liters/gallons of capacity as possible.
For best results, stay away from ionizers with filters that can’t handle at least 1000 gallons. Any filter with less capacity than that will need to be changed every 3 to 6 months. And that can be pretty annoying.
Ease of Use
Using an ionizer shouldn’t be much of a problem. Sadly, not all manufacturers understand that.
That’s why we often advise users to go for the most practical models possible. That means getting the easiest-to-use designs out there, often with backlit LCD, if possible.
Buttons are also necessary. Most features from these machines are activated through these buttons, so we recommend getting models with as many modes and/or functions as possible.
And lastly, make sure you don’t need to do much more than pushing a button, and that’s it. Some models may require extra steps which can be super annoying – so stay away from them.
Similarly to the operation of a water ionizer, you also want to have a more enjoyable time doing so.
That’s why it is ultra-helpful to go only for models that you can install in a breeze. For that, get portable models if possible, especially those with a countertop design.
These models allow you to install the machine in just a few minutes, even on your kitchen faucet.
But sure enough, this is a little more difficult to get right than other features. What we recommend is considering the design above anything else – that should tell you everything you need to know about the ionizer setup.
Types of Water Ionizer: Which One to Choose?
Now that you’ve gone over all the different factors to consider before buying, we need to show you all the types of ionizers you can pick.
This will help you choose the best alkaline machine for your needs, depending on what works better for you.
Here are the three types of ionizers you’ll find:
This type of machine works independently. That means it is not connected to any water source like most ionizers are.
To make it work, you will have to fill the machine with the water and start the purifying process. Often, these pitchers offer the chance to increment the alkaline levels as well as reduce acidity and increase oxygenation.
You will have the chance to enjoy alkaline-rich water as well as a highly oxygenized one that makes it even healthier & beneficial.
These systems often come with just a few buttons and/or functions. You just need to add the water and press any of these buttons for the machine to do its job.
The best of all is that you won’t need to install them. Often, they work like blenders, so you will only have to connect them to an outlet, pour some water in, and that’s it. They will do the job.
Countertop Water Ionizer
A countertop alkaline water machine offers a pretty different operation than a pitcher.
This one is indeed connected to a water source, often a faucet. The water will pass through the machine and then deliver the water directly through the faucet or through a hose attached to the machine.
What makes countertop ionizers effective is that they work directly on the countertop, so users can change their functions accordingly, depending on their needs. For example, if you need highly alkaline water, you can change it with the touch of a button from the countertop.
These machines often have pH and ORP levels to choose from. And they contain filters that purify the water as well as adding alkaline levels or reducing the acidity.
Overall, they’re pretty effective and are worth having. Still, installation can be complicated, especially if you have other things on the countertop with minimum space.
Under-Sink Water Ionizer
If a countertop model doesn’t work for you, and a pitcher ionizer feels like too much work – then you can always go for an under-sink model.
This one goes directly below the sink and offers the chance to save some space as well as work conveniently without much handling.
Some under-sink models come with their own faucets that allow easy use. This prevents users from having to get under the sink to change water modes every time they’re processing water.
That also means they come with their pH and acidic levels to change when needed. You won’t have to stick to a pre-set level of purification or ionizing – you can pick the right one.
Overall, these are practical and useful – but can be a little hard to install if you don’t have much under-sink space. Apart from that, these are more permanent solutions, so the installation usually requires a lot of work.
As you can see, there are so many different options to choose from that you won’t have it easy.
Picking the next water purifier may take you a few hours or even days. But make sure to follow our advice & recommendations to reduce the time and effort.
For us, picking the Bawell Platinum Alkaline Water Ionizer will be the wisest choice. Despite being the most expensive model in the list – it is the best water ionizer without a doubt. It comes with every single feature you need on a countertop ionizer, and it lasts a lifetime.
But all other models in the list are also worth considering, so don’t overlook them. You will get the right model as long as you follow this article. So don’t hesitate and pick one now!
