About Water Ionizers: What You Need to Know Before You Buy

7 Things to know when buying water ionizer.

What Makes A High Quality Water Ionizer Different? 7 Things You Need To Know Before You Buy a Water Ionizer.

Purchasing your own water ionizer is an life-time investment. It’s all the more important the water ionizer of your choice is high quality and will last a life-time. Dr. Dave Carpenter outlines what to look for when buying a water ionizer. Discover what makes a premium high quality water ionizer different than others, before you buy a water ionizer so that your whole family can enjoy drinking clean and healthy alkaline, ionized water.

1. A Water Ionizer Should Be Self-cleaning and As Low Maintenance As Possible

When using a water ionizer I’ve learned that people generally don’t maintain their equipment as they should. When this happens I’ve seen everything from mold to bacterial over-growth occur along with a buildup of minerals on the electrodes that pretty much neutralize the impact the water ionizer can make on the water. Believe me when I say that you don’t want that! Life is busy. So I think it’s very important to have a water ionizer machine that is self-cleaning and as low maintenance as possible. The more maintenance required the more likely there will be problems over time for the majority of us.

If you’ve ever seen the element in an electric hot water heater that was pulled out after a few years of use you’ll understand quickly how minerals (also called “scale”) attach to metal that has electricity flowing through it. These minerals quickly reduce the efficiency of the water heater and they will quickly reduce the effectiveness of a water ionizer too.

Ways High Quality Water Ionizers Do Self-Cleaning

Based on my own experience with water ionizer users, the best solution is for your water ionizer to do as much as possible for you so that you don’t have to take the time or even remember. The best water ionizers have a fully automatic cleaning process that changes the polarity on the electrodes automatically and frequently. The more often the polarity is reversed, the more evenly the plates are bathed in the cleansing acidic water which prevents this mineral buildup. Engineers I’ve consulted with tell me that this would be in a 1:1 ratio, meaning that for every minute of flow there would be another minute of flow where the polarity to that electrode is reversed. This is a huge factor in the life and performance of your water ionizer.

Another method is using citric acid overnight in the ionizing chamber to descale the plates. This is only effective as long as the machines do NOT drain during this period of cleaning.

2. Good Water Ionizers Regulate Incoming Water Pressure

Water pressure is different from place to place too. Ask about how flexible the water ionizer you are considering is when it comes to water pressure. If it only performs well at a particular water pressure then you may have some issues as most water systems do not supply water at a set pressure all the time. If the pressure is high then the water passes quickly through the ionizing chamber and the water has less time to be restructured during the process. The longer it is in the chamber the more influence the electricity has on it.

3. Know Your Source Water Before You Buy A Water Ionizer

Learn as much as you can about the type and quality of water in your area too. Knowing if your water is “hard” or “soft” will make a huge difference for your water ionizer. “Hard” water is really water with a higher mineral content than water considered “soft.” If you see mineral buildup on your shower doors, tiles and faucet screens or aerators you likely have hard water.

Simple Home Test For Hard Water

You can do a fairly reliable but unscientific test to see if you have a problematic level of hard water in your home by doing this simple test with liquid dish washing soap:

  1. – Take a clean empty 16 to 20 ounce plastic bottle that has a cap.
  2. – Remove the cap and fill the bottle to 14 ounce full with water.
  3. – Add 10 drops of liquid dish washing detergent.
  4. – Shake well

If the soapy solution foams up quickly you are good and the water not too hard. If the solution does NOT foam up but instead creates a milk-curd-like or soapy film on the water surface then the water is likely “hard.”

Soft Water Makes Water Ionizers Work Harder

Soft water (contains few minerals) tends to make a water ionizer work harder because for an ionizer to work there needs to be alkalizing minerals in the water. If you live in a city it’s likely the water quality, hardness and pressure is more regulated (not necessarily better by the way) than if living in the country and using a well or tank.

After sharing about water ionizers for years, I’ve learned the hard way that many water ionizers just don’t adapt well to certain types of source water. Make certain that the Company that’s selling you the water ionizer understands the type of water you have and how to make the water ionizer machine work optimally with your source water. If a salesperson tells you that their water ionizer machines work in all types of water without any modifications or adjustments find a different sales- person to work with. It’s simply not true.

4. Does the Water Ionizer Filter the Tap Water Efficiently?

One of the most important considerations in purchasing a water ionizer is the water filter being used to clean the tap source water before it goes through the electrolysis process. You don’t want to consume alkaline, ionized water full of contaminants such as pharmaceuticals, agricultural chemicals, heavy metals, organochlorines, etc. because these will become more bio-available in your body once the water carrying them is ionized. Being more bio-available means that they will have a more profound impact on the body…you don’t want that!

Many ionizers use a simple Granular Activated Carbon filter that mostly reduces chlorine. That’s not very effective! In the long run I believe having the cleanest mineral rich source water to be the single most important aspect of getting the best alkaline, ionized water day in and day out.

5. Water Ionizer Electrode Composition, Plate Size, and Surface Area

Does size matter in ionization of water? For a long time I believed that the size of the plates of a water ionizer had a huge impact on the water produced. That may have been true at one time but it is no longer true today.

Technology has come so far that plate size has much less to do with the changes that occur to the water than does the design and delivery of the power to the plates. Consider that electricity, just like water, always follows the path of least resistance. Some manufactures, understanding this, have designed their plates to move the electricity across the plates in a manner that brings a more even influence on the water touching the plates. The single most important factor in this discussion, however, is the source water itself. Every water ionizer will perform better with the right source water.

All of the well-built water ionizers use titanium plates coated with platinum for longevity and performance. Stay away from any that do not.

I hired an engineering firm familiar with this technology to evaluate plates in all of the different machines that I possess personally and their opinion was that all of them were pretty similar in the grades and amounts of platinum in the plates per square inch. Samples indicated different degrees of purity in the titanium used. Although that might impact the efficiency of the electrode to a degree the firm stated that design of the electrode was a much bigger factor overall.

Does Water Ionizer Power Output Matter?

The more electricity (watts) per square inch of electrode means the more efficient the water ionizer will be in changing the water.

This is easily understood when we look at a light bulb. For years the light bulb with the highest wattage was the brightest. But now, with new technology, some of the lower wattage light bulbs outperform their much higher watt ancestors. For example, I have a 26 watt energy smart bulb from GE that replaces a 100 watt bulb because it is more efficient at using electricity via better design concepts and it lasts longer too.

This concept holds true with water ionizers as well. The more efficient designs get more of the electricity to the surface of the electrode so there are more volts and watts per square inch than found in some machines with larger plates and even larger power outputs. You want a water ionizer machine that gets the power to the water so to speak…as that is the factor that supports increased ionization of the water.

Increased ionization = greater negative ORP = more free electrons in the alkaline water = greater potential for the neutralization of free radicals in your body.

6. Filter Life of Your Water Ionizer

The life of the filter really depends on the quality of the source water and also the type of filter that is being used. The dirtier the water going in the faster the filter will need to be replaced.

7. The Lifespan of Your Water Ionizer

One of the biggest issues I’ve seen with water ionizers is that they get scaling or mineral deposits on the electrodes (plates). This quickly reduces the efficiency and people soon complain that their water ionizers aren’t working any longer. And that’s basically true as their water ionizer is no longer restructuring the water like it did when new. Cleaning is essential as I mentioned previously and really the key to longevity and performance of any ionizer.

If you store your water ionizer for any length of time I would advise that you drain the filter carefully and store it in the refrigerator until ready to use again. And be sure to completely drain your water ionizer carefully as well. This is a must!


  • Self-Cleaning Water Ionizers: It is very important to have a water ionizer machine that is self-cleaning and as low maintenance as possible.
  • Good Water Ionizers Regulate Incoming Water Pressure: The longer the water is in the ionizing chamber the more influence the electricity has on it, and better ionized water is produced.
  • Know Your Tap Water: Before you buy a water ionizer know what type of water comes to your home, hard or soft water. Naturally occurring alkalizing minerals are vital to making ionized alkaline water.
  • Water Filters: One of the most important things look for in purchasing a water ionizer is the water filtration being used to clean the tap source water before it goes through the electrolysis process. Low quality water ionizers do not filter contaminants such as, pharmaceuticals, agricultural chemicals, heavy metals, organochlorines, etc.
  • Plate-Size Doesn’t Matter: Some believed that the size of the plates of a water ionizer had a huge impact on the ionized water produced. This is no longer true today as technology has advanced.
  • Power Output (High Wattage) Doesn’t Matter: Efficient water ionizers get more of the electricity to the surface of the electrode, so there are more targetted volts and watts per square inch than found in water ionizers with larger plates and even larger power outputs.
