A water ionizer is a complex alkaline water machine, and some systems come with more smart features than other. There are several characteristics of ionizers that we look for when picking the best one. If you have been trying to find alkaline water benefits, we have picked the top machines on the market.
We review the best water ionizers available based on our test results. Our experts look at water clarity, alkaline level, smart features, size, and cost.
What Do Water Ionizers Do?
Water ionizers (also known as alkalizers or alkaline ionizers) are water filtration devices that raise pH levels by using electrolysis. They separate water into acidic and alkaline components, changing the structure of the liquid until the pH is much higher. Studies suggest multiple health benefits.
Check For These Three Features Before Buying:
High Alkaline Water pH Range
Ideally, you want a water ionizer machine that has a high pH range. Most alkaline water machines have an indicator to clearly show you when the water is alkaline, which is any pH over 7.
Most water ionizer machines have a range of alkalinity, however. Higher-quality water ionizers have more alkaline water benefits. You may be able to control the alkalinity through a panel, allowing you to create pH level 1 water up to a pH level 14 result. While mildly alkaline water is best, you can use the alkaline water machine to create all types of water levels depending on whether you want to disinfect or cleanse your drinking water.
High Number of Electrolysis Plates
Every water ionizer machine has electrolysis plates. Most come with 3 to 5 plates, but these are lower numbers. The real machines have 7 to 9 or more plates. However, having more than 10 plates offers amazing alkaline water benefits. Having more plates also helps with the ionized water machine’s power. You get a larger range between low and high pH.
It’s important to look at the number of plates of each machine, as well as how big the machine is and what the plates are made of. They could be flat, mesh, or slotted plates.
High Oxidation Reduction Potential
You can also change the ORP levels. Oxidation Reduction Potential (ORP) is how we measure the degree to which any material or substance can oxidize or reduce another substance. Positive ORP readings mean that the substance is an oxidizing agent. Negative ORP readings mean that the substance is a reducing agent. These are amazing alkaline water benefits that you won’t find with every water ionizer machine.
Most types of regular tap water and bottled water are considered oxidizing agents because they have a positive ORP. After going through an water ionizer, alkaline water becomes an anti-oxidizing agent, which gives it a negative ORP. This helps in the reduction of free radicals within the body.
Tyent UCE-13 Plus
Under sink water ionizers are larger, stronger alkaline water machines. The UCE-13 Plus water ionizer is one of the smartest filtration devices on the market. For one, it has an LCD touchscreen with a hydrogen boost button that instantly boosts the molecular hydrogen. There are two internal filters that are rated for six months or 950 gallons.
The high-grade activated carbon and composite ceramic filters can filter out 99.99% of all contaminants. The filter is rated for 0.01-micron. Tyent USA designed their under counter water ionizer to work just like kidney dialysis machines. The ceramic filter also has an added bonus of adding electrolytes to the final purification stage.
With 13 titanium plates, the Tyent UCE-13 Plus has a pH range between 1.7 and 12. While some ionizers don’t have extremely low acidic levels, you can easily program the pH levels to your liking.
However, the best part about the Tyent under sink water ionizer is the faucet with a touchpad. You can easily use the buttons to filter and ionize the water to your liking. It also has an ORP range with -1050 mV to start. There are 55 different settings you can control with this faucet attachment.
What We Liked About the Tyent UCE-13 Plus Water Ionizer
The filtration on Tyent’s devices is always superior to competitors. The 13 titanium plates are solid and mesh medical-grade titanium. These are large plates that span 385 square inches. We expected this under sink alkaline water ionizer to have a 99.99% contaminant-free result. This includes chlorine, chloramine, lead, arsenic, pesticides, bacteria, cysts, and more.
There are 7 basic settings that you can use with a Turbo button. This includes 3 basic alkaline levels, 3 acidic levels, and a neutral level. You can preset each one of these so that you get the perfect pH level each time.
The Tyent UCE-13 Plus also has a flow rate of half gallon per minute, and it has a alkaline water filter life indicator that lets you know when you need to change filters. Customers report that filters typically last longer than six months.

Secret Health Benefits of Drinking Alkaline Water
One thing we want to mention upfront is that alkaline water or ionized water has not been extensively studied to know if these benefits are significant for everyone. The best water ionizers have a high pH range and titanium plates as well as a touch screen with customized presets. However, many posts on Reddit and reports from customers show that ionized water from a water ionizer led to significant improvements in skin, stomach problems, and overall health.
Improves Your Immune System
Water ionizers also provide other alkaline water benefits for your body. Regularly drinking alkaline water boosts your immune system considerably. When you put yourself in an alkaline state, you limit the number of free radicals in your system. It helps cleanse the toxins from your body and helps your long-term health.
Did you know that NBA athletes prefer FIJI water to any other in their locker rooms? When you have alkaline water, your body can achieve a higher level of hydration than when drinking out of the tap or water fountain. One study from 2010 conducted by the International Society of Sports Nutrition found that drinking alkaline water with a pH as high as 10 provided more hydration for the human body.
Alkaline water machines offer the same kind of benefits. This is because FIJI water has an average and natural pH of 7.8. This is slightly more alkaline than other water, which typically has a pH of 6 to 7.
It’s an Antioxidant
Another one of the alkaline water benefits is that it comes with antioxidants. The best water ionizer should include a hydrogen boost to ensure there are even more antioxidants. You could turn your home into an antioxidant paradise with alkaline water that freely flows from your faucet.
One of the best reasons to do so is that ionized water has ORP (Oxidation Reduction Potential) levels, which means it works against free radicals in the human body.
Helps with Acid Reflux
Do you experience heartburn or acid reflux recently? One study from Daniel P. Heli found that alkaline water from a under counter water ionizer soothed symptoms from acid reflux. This is because it helps with acid-base balance, which basic tap water cannot do.
If you have acid reflux problems, drinking water from an under sink alkaline water ionizer can calm your stomach. With its ultra-hydrating properties, alkaline water can improve your condition and settle your digestion within minutes.
Slows Down Bone Loss
This is one of the main benefits of alkaline water from an under counter water ionizer. A small study noted that alkaline water aided in deceleration of bone loss in some patients. While this needs further research, there are some indicators that drinking slightly elevated alkaline water helps the body with calcium.
Studies have shown that junk food can heighten the acidity in your system. To neutralize the acid in your system, your body produces fat cells, which creates weight gain. Drinking alkaline water produced by a water ionizer daily can alleviate the acidity and stop the weight gain, which are awesome alkaline water benefits.
Convenient Filtered Water
You can easily call this one of the better alkaline water benefits. Your home could have running filtered, alkaline water straight to your sink faucet with an under counter water ionizer. Water ionizers come in countertop and under sink form factors. While some under sink filters add alkalinity to your water, it can’t be tested or adjusted. When using an under sink alkaline water ionizer, you won’t have to drink alkaline water with low pH from a bottle when you’re producing spa-quality water straight from your sink.
Water Ionizer FAQs
How Does An Alkaline Water Machine Work?
Before investing in any water filter, you should know how it works and all the alkaline water benefits. Most alkaline water machines hook up to your kitchen sink, but there are hybrid types, countertop ionizers, and the under counter water ionizer. Each of them has the same process to filter your water so that it’s alkaline.
Ionizers are built with a two-step filtration process. The first step is to filter out any harmful components in the water, such as chlorine, sediment, odor, taste, organic waste, bacteria, and other things that shouldn’t be in your drinking water.
Secondly, an electrical charge and special plates are used for electrolysis, which changes the pH level in the water. Some ionizers let you control the pH level, allowing you to create lower pH water for cleaning purposes or high-quality alkaline water.
Do All Ionizers Come With a Built-In Water Filter?
It is important to check specifications on any water ionizer to see what filters are included. Some include multi-stage process with over 10 steps, including carbon block and reverse osmosis filters.
However, you should be careful with certain ionizers that have a short filter life and a custom filter. These are difficult to maintain and may cost more after a few months.
What’s The Difference Between Countertop and Under Counter Water Ionizer?
Countertop ionizers sit next to the kitchen faucet and make it easy to get alkaline water whenever you want. The only difference between these two ionizer types is how they are installed. In addition, most under sink alkaline water ionizer are more expensive and have faucet controls, rather than the touch screen LCD displays on countertop filters.
Is It Safe To Use Water Ionizers?
Yes, as long as you keep the alkaline levels between 7 and 9 for your drinking and cooking water. Many ionizers offer custom settings that let you turn down the pH to under 3, which creates good water for cleaners and disinfectants. However, these should not be ingested.
There are a lot of alkaline water benefits that come with ionizers. However, these are mostly reported by users as the systems have not been fully studied or researched. If you have issues with your water source, ionizers may not be as effective as well. Most experts recommend using a water ionizer with a multi-stage filtration process that includes reverse osmosis for this reason.
How Do You Install A Water Ionizer?
Most of the units have their own installation process, but it’s typically the same for countertop and under counter water ionizer. The first step is that you must connect the water ionizer to the water line with under sink filters. Countertop filters typically just connect to the faucet.
In some cases, you may need to change your kitchen’s tubes and connections depending on the size of the under counter water ionizer. If a second faucet is necessary, you may also have to create a hole using a drill to pull the faucet through. For this reason, countertop filtration devices are easier to install and use.
Does Ionized Water Stay Alkaline Forever?
The truth is that alkaline water does not keep its pH. After 3 days, the pH level drops significantly. However, if you store alkaline water, it can maintain its pH for up to a week.
