We’ve given you many options to choose from in our list above. At this point, you might be a little overwhelmed. In this section, we’ll give you all the information you need to better understand these products, and to pick between the options above.

By expanding your knowledge of water ionizers, you can choose from the products above to settle on the best option for your home.

What are water ionizers and what do they do?

If you’re a true newcomer to this product category, it helps to start with the basics – what exactly is a water ionizer?

A water ionizer is a device which aims to increase the quality and health benefits associated with drinking water. The device is hooked to your plumbing and sits on your countertop. The device then uses a process called “electrolysis” to separate water into acidic and alkaline streams. This “alkaline” water is where the health benefits are said to reside.

Therefore, water ionizers are essentially working as “water electrolyzers”. The electrochemical process created by the machines will siphon water to create water that is more acidic (for household disinfecting purposes), and water that is more “alkaline” (for drinking purposes).

Water ionizers also influence the negative Oxidation Reduction Potential (ORP) of the water. The ORP is the ability of the water to act as an antioxidant. If the water has a more negative ORP rating, then it will be a better antioxidant.

Of course, not all water ionizers are the same, and some offer increased functionality over others. Our guide above does a great job breaking down what you can expect from these products.

What Is Alkaline Water and What Are The Benefits of Drinking It?

So, you’ve seen a lot of talk and a lot of hype about “alkaline” water, but you aren’t even sure what it is! The section directly above explained how water ionizers work to create alkaline water, but let’s talk about the water itself.

Alkaline water refers to the pH level of water. The pH scale goes from 0-14, with 0 being most acidic, 14 being most alkaline, and 7 being neutral. Normal drinking water tends to be close to 7, or neutral. A water ionizer makes the water more “alkaline”, raising the pH up to around 8 or 9. This is what gives the water its ability to help “neutralize” the acid within your body.

Many who regularly drink alkaline water also attest to various benefits – such as reducing acid reflux, superior hydration, skin health, weight loss, colon-cleansing, and other beneficial properties.

Buyer’s Guide for Water Ionizers

We’ve gone through many different options throughout our article. The best way to choose among different options on the market is to break down your decision into various factors. Decide which factors are most important to you, and use this hierarchy to make your choice.

pH and ORP

The first major factor of consideration with water ionizers is pH and ORP. Of course, the primary purpose of a water ionizer is to increase the pH and to output alkaline water. So, you want a machine that offers a wide range of pH levels.

Generally speaking, the more options the better. The wider the range of pH, the more applications are available. You’ll have everything from drinking water, to cooking water, to cleaning & sanitizing water. Generally speaking, you want a pH range of at least 3.5-11.

You also need to consider the antioxidizing properties of the water, which is given by ORP. An ideal range for ORP is typically around +800 to -600. Negative ORP represents a water with more antioxidizing properties.

Filter Life

Many water ionizers also offer filters for water purification. This adds even more benefits to the drinking water, removing acidic substances and harmful sediments. Pay special attention to the length of the filter’s life.

The filter ends up being the primary addition which can increase your water iodizing costs in the long run. Look for a filter which doesn’t need to be replaced so often. This not only saves you time, but saves you the hassle of having to constantly buy and replace your filters.

Settings and Usability

Typically, ionizers will break down the pH and ORP levels into a variety of pre-sets. These pre-sets are activated using buttons on the device’s front. Some offer more or less pre-sets (typically between 4 and 8), with each offering higher and lower levels of pH. There will usually also be a setting for non-alkalized purified water.

Look for a device that makes it easy and straightforward to change your settings. Many devices on our list organize their settings by levels of pH, and also include pictures to indicate what each setting is best for (ex. Cooking, drinking, brewing coffee, washing your face, etc.). The best machines also include an LED display for you to monitor current levels of ORP and pH.


Price will always be a major consideration in purchasing a new appliance. We think a better consideration is price vs. quality. Settle on a price range that you are comfortable with, and then survey the options within that price range. This allows you to get the most value for your money. Price is a worthy consideration, but only if it is considered among other important factors.
