Alkaline Water Machine (Ionizer) Buyers Guide

What are Water Ionizers?

A water ionizer, which you might also hear it referred to as a water alkaline machine, is a home appliance consumers can use to raise their drinking water’s pH level. These systems accomplish this goal through the use of electrolysis. That process separates the water streaming into the system into acidic and alkaline components. 

Each water ionizer features platinum and titanium plates ions from the plate’s exchange with the water. As a result, the water’s pH level is more alkaline. That means the best ionizers water machines alter the water’s pH levels to increase the alkalinity.

Learn more about what alkaline what is exactly here.

How Does a Water Ionizer Work?

These units feature construction from metal or plastic electronic filters, making a water ionizer machine typically the size of a toaster. Despite their size, these units contain everything to alkalize water. Water ionizers usually attach to the kitchen faucet and have direct access to the home’s water supply. In doing so, all of the home’s kitchen tap water is ionized by the machine before using it for cleaning, cooking, or drinking.

Each time tap water moves through an ionizer machine; the carbon minerals convert to hydrate minerals. Carbon minerals include calcium and magnesium minerals. This process is also referred to as controlled electrolysis.

When breaking down the process, it looks like this:

  • Water enters an ionizer machine through a faucet attachment, which is typically a flexible plastic tube.
  • The first stage involves the water going through a filter to remove all harmful contaminants, including chemicals, metals, and pathogens.
  • The next stage involves the filtered water moving into a chamber that contains electromagnetic plates.
  • The last stage involves negative electrons attracting to the water’s positive ions and negatively charged ions attracting to positively charged electrons. 
  • That process produces reduced ionized water and oxidized water that flows separately from each other.

What to look for when buying a water ionizer

Finding the best alkaline water ionizer might be overwhelming for some, considering the wide variety of options available. However, you can narrow down your search for the best machine by thinking about how you want the alkaline water ionizer to meet your needs. Here are some factors to consider during the selection process:

pH and ORP range

When selecting a water ionizer, be sure its pH range is between four and 11 with at least a negative 800 ORP. Water’s pH typically ranges between zero and 14, with seven being neutral. When using this water for drinking, the best water ionizers should be seven or above and should not exceed 10.

Also, if you want to make sure you get the benefits of hydrogen in your water check out specific hydrogen water machines as well. 

Number of plates

One of the essential parts of an ionizer is its plates. The main reason is that it’s where the tap water converts to ionized water. Consumers can choose from grid, mesh, flat, and slotted plate types. The grid is the best quality, and the slotted is the lowest quality.

Look for how many plates that the ionizer uses. The unit is going to have better efficiency if it has more plates. The main reason is that when there are more plates, that creates more power. That power enables the ionizer to produce water featuring the most optimal ORP range.

Under the Counter vs Countertop

If you don’t have much counter space, then a countertop water ionizer isn’t the best option. In that case, choose an ionizer water system that can go underneath the sink. Even though an ionizer features a compact design, you might not want it to show next to your kitchen faucet.

Filter efficiency

Look for water ionizers featuring at least two filters with long cartridges. Ceramic filters are considered the best because they effectively remove bacteria, microbial cysts, and protozoa. You must also consider the lifespan and cost of filter replacement, in addition to its capacity.

The home’s water quality is another factor you must consider when looking at water filters. The level of use is another contributing factor regarding how often changes must occur. If the home’s water contains high levels of contaminants, then they’ll require filter changes more often.

Simplicity of installation

There’s no need for worrying about whether you can install the water ionizer or not for those who aren’t good at DIY projects. These units are exceptionally simple to install. You’ll find this is especially true for countertop units. Typically, these units come fully assembled, and you won’t need specialized tools.

Ionizers that install underneath the counter are a bit more complicated than countertop units. However, even if you don’t have a significant amount of mechanical skills, it’s still possible to install this unit without help.


Understanding how much an ionizer cost is the best way of determining how much you can spend on one. Budget options can start at approximately $600, while higher-end models can cost several thousand dollars. Keep in mind when shopping for an alkaline water machine that some of the best ionizers feature at the highest prices.

Warranty and support

Look for at least a ten-year warranty if you want to purchase a mid-range alkaline water ionizing machine. However, keep in mind that the best water ionizers are going to have a lifetime warranty. Look at customer reviews to learn more about their good or bad experiences with the company.


When you have the right alkaline water machine information in front of you, it’s possible to choose the best water ionizer for your home.  Not only do you want it to contain a water filter, but you also want it to create alkaline water. Producing the best water means the alkaline water ionizer machine features the right pH, ORP, water filter efficiency, and the highest quality plates. 

We love the Tyent UCE-11 ionizer for its dual filtration and programmable touchscreen. We also like the Aqua Ionizer Deluxe because it’s budget-friendly and can fit on the countertop or underneath the sink.
