The Best Alkaline Water Machines for Healthy Immune System

Writen by Ronald Brown

Fact checked by Natalie Bridges

Drinking alkaline water may give you certain health benefits. This water contains alkaline minerals along with negative oxidation-reduction potential. More negative ORP means the more antioxidizing water is. Alkaline water also includes a raised level of pH versus typical drinking water. So, if you’d like to improve your health, you might be shopping around for the best alkaline water machine.

With the right one, you’d be able to get its antiaging benefits and colon-cleansing properties. It might also improve the immune system and the body’s hydration ability. Choosing the top-quality alkaline water machine for your home or business requires knowing what aspects will have the most impact on the product’s performance. Check out the three most crucial elements you’ll need to pay attention to while shopping for an alkaline water machine.

  • pH Range: Most alkaline water machines can elevate water pH by one-half or one pH point. Others can add more minerals to the water to bring the pH to 8 or 9. The ideal product depends on your water’s current pH level and comparing it to the alkaline water machine’s rated pH increase.
  • Ionizing Plates: Alkaline water machines have ionizing plates, separating alkaline water from the acidic component. These technologies produce more hydroxyl ions and fewer hydronium ions to elevate the pH level. Hence, the more ionizing plates an alkaline water machine has, the greater its pH-raising capabilities. However, it is worth noting that an 11-plate device has a higher price tag than a five-plate unit.
  • ROP Rating: One advantage of alkaline water is its antioxidant capability, defined by its reduction-oxidation potential. It describes alkaline water’s ability to oxidize free radicals and reduce their levels. Experts recommend an alkaline water machine with a low or negative ORP rating for maximum antioxidant effects.

To find what’s yours, here is help. In the following, let’s check out the highest-rated water ionizers on the market.

What Is An Alkaline Water Machine/ Who Is This For


The alkaline water machine, also called a water ionizer, is an appliance that works by raising the pH level of drinking water. It uses electrolysis to separate the stream of water into alkaline and acidic. Alkaline water machines were first famous in East Asian countries and Japan before eventually entering the shores of Europe and the United States.

Many of the machines featured earlier are compact and lightweight. They are also easy to install and operate. Plus, they don’t require much maintenance. These machines also help save the environment because you don’t need to buy bottled water, eventually reducing environmental waste. The alkaline water machines are also made of quality components, so users don’t need to spend on repairs often. From time to time, they only need to replace the filter based on the manufacturer’s water condition or instruction.

These alkaline water machines are for those that want to save money from buying bottled water. They are also ideal for those looking for a great solution to keeping their loved ones healthy by drinking ionized water. It is also for those that want to drink water with minerals and antioxidants.

Overall, an alkaline water machine is an excellent investment for your family. It can create pH-balanced and healthy water that can improve health and support the immune system. You might want to check out one of those that we reviewed earlier to help you pick the right machine for you. Remember, these machines have different capacities that you should check when comparing your options. Nevertheless, you can refer to the buying guide below for more information.

How Does It Work

The best alkaline water machine is an innovative and powerful machine. It can help transform tap and everyday water into one that is rich in antioxidants and minerals. However, remember that ionized water is in two forms, acidic and alkaline, each with its specific benefits. Each of them is also used for an application. These machines typically use titanium plates and power so that they can create acidic and alkaline water. They can help in creating water with high or low pH levels with antioxidants. It is also with molecular hydrogen and contains small molecular size or micro-clustered water.

How it works is that the source of water is flowing into the ionizer. And with electrolysis, the anions and cations are then separated into streams. This machine features a precisely controlled ORP and pH level that you can find in the adjustment settings. Typically, those we’ve featured here are with seven water settings. They can help create solutions with pH ranging from 3.0 to 11.5 based on the model you chose.

What Are The Different Types Of Alkaline Water Machines


Alkaline water machines work by increasing the pH level of drinking water. They can do this in different ways. The way they ‘ionize’ water can form the basis for the classification of these machines. Alkaline water machines can also be classified according to their fundamental design. Here, we are going to examine both ways of organizing alkaline water machines. This should help you decide on what type or brand of alkaline water machine is most suitable for your home.

According to Design

The easiest way to classify alkaline water machines is by their design. We have three prevalent designs of such water systems. These include countertop types, under the counter types, and convertible devices.

  • Countertop

These water ionizers are devices that you can place on your countertop. They are straightforward to install and use. Most devices have a built-in water compartment for you to fill up. There are also countertop alkaline water machines that can be connected to your household water line.

  • Under Counter

These water machines are like countertop devices. It only differs in its location. The majority of under counter alkaline water machines require a connection to a water line. These machines require the necessary plumbing skills for a successful installation.

  • Convertible

This alkaline water machine marries the convenience of a countertop model and the durability of an under counter design. You can place this kind of device on your countertop or under it if it calls for it.

According to Ionizing Plates

Alkaline water machines have different components. The essential element is the ionizing plate. This is where the alkalinization of the water takes place. It is where the charged particles in the water get separated into alkaline and acidic components. Alkaline water machines typically come in one of four types of ionizing plates.

  • Grid

This is the most efficient ionizing plate on the market. They are often made of drop-forged, high-quality materials. This gives the plate remarkable durability. The design of Grid ionizing plates allows for the more efficient movement of electrons along its edges. The Faraday Effect describes that electrons prefer moving along the edges of an object than on the flat surface of the same object.

  • Mesh

Mesh ionizing plates are like Grid plates when it comes to efficiency. However, they are not as durable as Grid plates because Mesh plates often feature cast metals. This type of ionizing plate has a shorter service life than Grid plates.

  • Flat

Flat ionizing plates are not as efficient as either Grid or Mesh types, owing to the Faraday principle. They are also not as durable as Grid plates. However, Flat ionizing plates can last if Mesh plates.

  • Slotted

This ionizing plate is the least efficient and least durable among the different types. Its main advantage is its low price. Given its unreliability and questionable efficiency, alkaline water machines that have slotted ionizing plates tend to be more expensive in the long term as they do not last that long.

Advantages And Disadvantages Of Using An Alkaline Water Machine

Today’s rising popularity of alkaline water machines is mostly due to the claimed health benefits that alkaline water gives to your body. In this section, we will discuss some of the advantages of using an alkaline water machine and why owning one is a smart investment.

Alkaline water helps eliminate the build-up of mucus on colon walls. This is beneficial for the body, allowing and improving the body’s ability to absorb essential nutrients that are vital for health maintenance.

Cleanses the body

Aside from detoxifying your colon, alkaline water also contributes to cleansing your body. It helps in eliminating and flushing out acidic wastes and toxins that may have accumulated in your body over time to avoid any harmful effects on your body.

Weight control

Consuming alkaline water can also help control the body’s weight. This is because the body’s need for fatty tissues to protect your organs from acidity is reduced because of the neutralizing property of the alkaline water. Generally, alkaline water reduces body fat and fatigue for improved health.


But still, too much of anything can be harmful. Alkaline water from your machines may be safe for consumption. Still, excessive intake can have negative impacts on your body. Excessive use of alkaline water can potentially ruin the natural acids in your body, killing the good bacteria.

Besides, excessive alkaline water intake may result in skin problems and problems in your gastrointestinal tract. Alkaline water machines can also be costly, especially if you are looking for the top-quality available. But of course, with today’s technological advancement, budget-friendly devices that deliver almost the same quality as the expensive ones are also made available.

Buying Guide


Alkaline water machines are not your typical water dispensing contraptions. They have very complicated components that work seamlessly to separate alkaline water components from acidic ones. For this reason, one must be very careful when choosing the top-tier alkaline water ionizer for the home. Here are some critical factors you can consider when buying an alkaline water machine.

  • pH Range

Neutral pH is 7.0. We consider any pH level that is lower than 7.0 as acidic. Anything higher than 7.0 is alkaline. As such, a good alkaline water machine should be able to provide you with water pH levels of more than 7.0. The average pH level of drinking water we have in our homes is about 6.5 to 8.5. Tap water has an average pH of 7.5. Bottled alkaline water often has a pH level between 8.0 and 9.0.

There are alkaline water machines that can provide a modest increase in water pH levels. Others are more aggressive, allowing your water’s pH to increase by several points. Choosing the right pH range of the device will depend on the current pH level of your drinking water and the existence of any medical problem that can benefit from the consumption of alkaline water.

  • Number of Ionizing Plates

Alkaline water machines have ionizing plates that facilitate the separation of the charged particles into acidic and alkaline components. The plates promote the production of more hydroxyl ions than hydronium ions to tip the balance in favor of an alkaline solution.

The number of ionizing plates in an alkaline water machine can translate to its effectiveness as an ionizer. Most products we have on the market have five ionizing plates. More expensive brands often have 11 plates.

  • Range of Redox Potential

Another factor that any buyer of the alkaline water machine needs to consider is the range of the machine’s redox potential. The machine’s redox (oxidation-reduction) potential reflects its ability to oxidize and reduce oxidation levels in the body. We all know that oxidation can lead to excessive cellular damage, including irreversible damage to the structural proteins and DNA. That is why we also have natural antioxidants that serve to reduce or counter the oxidation processes in the body.

There is no ideal redox potential or ORP range of an alkaline water machine. However, proponents of alkaline water recommend getting a low ORP (oxidation-reduction potential) machine. The smaller this value is, the better the device is at improving the human body’s antioxidant capabilities.

  • Integrated Water Filter

The ionizing plate is one of the essential components of an alkaline water machine. However, this component cannot address the different particles or impurities that may be present in water. You may have bacteria, fungi, and viruses, as well as chemicals and pollutants. These impurities or contaminants need to be reduced if not removed from your drinking water.

Having a built-in water filter in the alkaline water machine is a useful feature. You can choose products with tiny filter pore sizes as small as 0.01 microns in diameter. The lower the pore diameter of the filter, the better it is to reduce total dissolved solids. The problem with tiny filter pores is that they tend to clog if you have water with a heavy concentration of dissolved solids.

  • Ease of Installation

It is also essential to the ease of installation of any given product. You do not want to spend a dime on its installation. Countertop machines are the perfect choice in such instances. If you have basic knowledge of plumbing, then an under-counter unit might be a great option.

Frequently Asked Questions (FAQs)

Can I store alkaline water?

Yes, you can store high pH water (or alkaline water), but with stricter requirements than natural or ordinary tap water.

We must understand that medical-grade alkaline water has a high-negative oxidation-reduction potential (ORP). The higher the water’s negative ORP rating, the higher its antioxidant properties. Hence, you do not want to lose this benefit by exposing alkaline water to heat, air, movement, and light.

Unsurprisingly, the best way to maximize alkaline water’s antioxidant benefits is by drinking it straight from the water alkaline and ionizer unit without storing it.

However, if you must store alkaline water, you should use a container made of non-reactive materials, such as stainless steel or glass, with an airtight lid. BPA-free and food-grade plastic is also an acceptable cheap alternative, but it may not be as good as my previous recommendations.

Fill the portable container with alkaline water up to the brim to limit air exposure. Store the water in a cool and dark place, or freeze or refrigerate it straight from the dispenser. You have 72 hours to consume it, although some observe an eight to ten-hour rule.

How long does it take to see the benefits of alkaline water?

You can start seeing the benefits of alkaline water as early as three weeks when your body has already adapted to the higher pH level. Most will need about four weeks before they start noticing antioxidant effects.

At the very least, it’ll take about four weeks before you start noticing the benefits of alkaline water. However, this milestone can vary based on various factors, such as the quality of your common water machine and the alkaline machine.

Also, it’ll take you 3-4 weeks to acclimate yourself to alkaline water and produce detox effects as your body tries to achieve pH balance. After two months of drinking from high pH filter water, you’ll be able to observe benefits such as reduction of acid reflux, lower blood pressure, and better hydration.

These figures are estimates because individual differences can influence how fast alkaline water can exert its benefits in the body. Brand variances can also impact alkaline water effectiveness.

For instance, many consider Alphion the top-tier alkaline water machine because it has nine pH settings and the most advanced platinum-titanium electrodes that deliver more electrolysis potential than other brands. It would be safe to assume that this product will bring noticeable alkaline water benefits faster than three weeks.

Do different people need to drink water at different pH levels?

Not necessarily; as long as the drinking water is within the range of 6.5 to 9.5, you’d be fine. Of course, if you need to neutralize the acid in your stomach, consuming alkaline water would be a good idea, but it doesn’t mean you have to drink water with a pH of 8 or 9.

However, if you change your water’s pH level and notice it adversely affects your health, you should stop doing so. No matter how beneficial users on Reddit or other online communities claim alkaline water to be, it’s not worth it if the water is causing you pain.

The takeaway here is: remember to pay attention and compare your body’s well-being before and after trying water with a different pH level.

What are the most trusted alkaline water machine brands?

Some of the most trusted brands for an alkaline water machine include Aqua Ionizer, Bawell, and Aqua-Ionizer Pro. Other reputable brands are those we’ve reviewed earlier. They are heavy-duty and quality to last long even with heavy use. You can also count on them for innovation and ease of use of their units. 

How much does an alkaline water machine cost?

There is no specific answer to this question. Some machines are on the lower-priced, and others are in the higher-priced spectrum. You can first decide how much you want to spend on this unit so that you can save time. However, you must balance quality and price to ensure that you’re getting the most out of your purchase. You can also refer to the reviews of the top picks available in different price ranges.

Is there a difference between alkaline water and Kangen water?

None. Both mean the same thing. Both an alkaline water machine and Kangen alkaline water machine make alkaline water. The difference is that Kangen water is the “trademarked name by ENAGIC Corporation.” So, no matter how you may call it, such water can infuse water with minerals, calcium, antioxidants, and other healthful compounds.

How to set up & use?

The set up of the machine depends on the type you bought. Some models are pitcher types; the others are machines. You can install it in minutes, nevertheless. As we always say, refer to the manufacturer’s instructions on how to install and use it for proper guidance. Nonetheless, it is not hard to set it up.

In many cases, you can connect it with your faucet, turn the water ionizer on, and set the type or set it on the control or touch panel. That’s it.

How to care & clean?

When do you clean your water ionizer? You must if you notice that the pH level of your water is dropping. Also, see if the flow rate of the water is slowing down. You might have to change the filter, according to manufacturer specifications. You might also have to think about natural ways of cleaning it like using a vinegar wash.

It can also be the time to clean if you see film forming on the alkaline machine’s spout. Finally, you should give cleaning to the device if you have not done it for a year or so or according to the condition of the filters.

For specific directions, you should refer to the user manual that comes with your purchase.
