Water ionizers or alkaline water machines as they are also referred to as have been gaining a lot of attention in the last few years thanks to claims that ionized water can do everything from curing diseases to helping with weight loss.

While there is no research or scientific evidence to back some of these claims, the fact is that having the best water ionizer in your house will come with a myriad of benefits.

Ionized water has restorative effects on your general health which can translate to things like reduced fatigue and acid reflux and neutralizing the free radicals that cause diseases to flourish.

Also, drinking ionized or alkalinized water also leaves you better hydrated. But, to ensure that the water that you get is ionized enough, you need to pick the right ionizer.

This piece is all about making shopping for a water ionizer a quick and easy process, and it does this by reviewing 7 top-rated water ionizers and with an in-depth buying guide.

What To Check Before Buying Best Water Ionizer?

To ensure that whatever you buy not only produces great tasting and healthy alkalized water, but also offers you great value for your cash, you need to watch out for the following things.

1. Under-counter or Countertop Water Ionizer

The installation option is one of the first factors to consider when shopping for a water ionizer to ensure it will work well for you. In most cases, you will need to choose between the under-counter and countertop models.

Ultimately the right choice for you here will depend on your personal preferences and the amount of space that you have in your kitchen.

Countertop Water Ionizers: If you are going to buy countertop water ionizer, it is important to make sure that it is compact enough so that it does not take up a lot of counter space.

Countertop models like Bawell 1195 also offer easy access to make filter changes easier, and they are generally more affordable than the under-counter models.

Under-Counter Water Ionizers: The under counter water ionizers are a relatively newer model. They are the kind that will require mounting under your kitchen sink and with a special water dispenser on the sink.

Installing them is a more complicated process and they are generally pricier than the countertop models. And although they take up more space than the countertop models, the space they take up is out of sight.

2. pH Range

The pH range is the degree to which a water ionizer can alter the pH of the water, and it is also one of the selling points of most water ionizer models.

Depending on the brand and model, some water ionizers will have up to 7 pH settings. Most of these settings are for ionizing the water but most units will also include neutral and acidic water setting.

An example of a good pH range is 2 to 12 which is what you get from most top-rated water ionizers like Bawell 2195. A wide pH range allows you to get water for different uses. For example, low pH water is ideal for disinfecting and cleaning while mildly alkaline water is the best for drinking.

3. ORP Range

Another important range to watch out for is the ORP (oxidation reduction potential) range which measures the water ability to oxidize or reduce oxidation in the body.

Overall, the lower the ORP value the better the water that the ionizer produces will be for your body. And this is because a high ORP causes negative oxidation which allows free radicals to attach the body.

A negative ORP value reduces the ability of the free radicals to attach to the body by giving them electrons so that they do not have to steal them from the body tissue.

Hence, when shopping for a water ionizer, it is always a better idea to look for a machine that offers a low ORP range or value.

4. Number of Plates

Because the plates are what will make actual contact with the water and turn it alkaline, neutral or acidic, you cannot overlook them when shopping.

A water ionizer with more plates is often more powerful which means that it will be more capable of producing water with a better pH range and ORP.

Most water ionizers will have between 5 and 11 plates. But it is worth noting that models with fewer plates are the cheapest while those with more plates are often quite expensive.

5. Built-in Water Filter

You also need to check whether the water ionizer you intend to buy has a built-in water filter or not. Luckily, almost all the top water ionizers from the leading brands will have a filter.

What matters most when it comes to the built-in filter is whether it offers effective filtration so that you not only get ionized water but also clean, safe and great tasting.

Some models like Aqua Ionizer Pro AWL-7000 will even have a built-in active carbon filter that will help remove chlorine taste and odor from the water.

Also, consider the lifespan of the filters and go for something that can serve you for 6 to 12 months before needing replacement.

6. Brands

As you shop for the best alkaline water ionizer, it is important also to consider the brand because you need to buy something from a reputable company.

There are a few companies that seem to have an edge over the others when it comes to the manufacture of water ionizers thanks to the quality, high-performance, and durability of their products.

Some of these companies that you can always trust to have a good water ionizer for you include Bawell, Air Water Life, Tyent, Pure Hydration, and Life Ionizer.

7. Ease of Use

A water ionizer also needs to be easy to use to serve you well. Because the ionization is often an automatic process, the ease of installation and cleaning the devices are some key determiners of the ease of use.

The best ones will be simple to hook up to your faucet without having to use any special tools. When it comes to cleaning, the most convenient and easiest to use water ionizers are the models that have an automatic self-cleaning feature.

How to Install a Water Ionizer?

Even when you get the best water ionizer machine, you will still need to install it correctly for it to serve you well. Although different models will come with specific installation instructions, here are the steps you will need to follow when installing most water ionizers.

What you Need

  • Countertop/under-counter water ionizer
  • Faucet diverter
  • 15/16-inch male adapter
  • Teflon tape
  • Screwdriver
  • Adjustable wrench

Step 1: Connect Faucet Diverter

Most water ionizer systems will come with a faucet converter and 15/16-inch male adapter, and if by any change they are not there, you will need to buy them at your local hardware store

If you have all the parts the first step is to connect the metal tube the ionizer. To do this you should remove the aerator at the faucet and make sure that you link the faucet diverter accurately with the faucet.

Step 2: Install Inlet Elbow

Next, you need to use some Teflon tape to wrap the inlet elbow and then use the screwdriver to screw it in place on the ionizer’s inlet.

Connect one end of a hose to the faucet diverter and then the other to the inlet elbow. Use the white hose for this because most units will come with different color hoses.

The next step is to connect the remaining hose to the bottom of the water ionizer on the outlet hole.

Step 3: Connect to Power

Now you can connect the water ionizer to a power outlet to power it on. Because most of these units will require some plug-in to work, it is important to make sure that you have a socket nearby before you start the installation otherwise you might not be able to use it.

Step 4: Test the System

Once the ionizer is powered up, you can now test the system to check whether everything is working well. You will need to taste the water to see whether it tastes different or not and also check for leaks. If the water taste is okay and there are no leaks then the system is ready for use.


And if you still do not know the best brands and models to go for, our top 7 water ionizer reviews above will help with this.

Every model on our list is top-notch quality, but if you are looking for something versatile that can both filter and ionize water, the Life Ionizer MXL-9 CT is your best bet.
