Compare: Performance

Comparing performance is important

WHAT YOU SHOULD BELIEVE – It is especially important when considering performance testing that you trust only facts. There are more and more water ionizer “comparisons” showing up on the Internet lately; how can you know which to believe? The following criteria will help you distinguish what is truly factual from that which appears to be, but in reality is not. (Click this link to understand pH and ORP)


  • Is the Test Independent, Third Party? You will want to know the party performing the test has no motivation for a specific outcome. Ideally a test would be performed by a company with absolutely no business ties to any brand. There are tests on the Internet that appear to be objective but in reality are not. In a few short minutes of internet searching, we found an interesting website depicting the ties of one comparison site to a specific brand. A good litmus test to apply is does the entity performing the test make income from the sale of water ionizers? Can you verify this?
  • Is the Test Scientific? Look for good solid scientific testing using:
    • Top quality instruments. Measuring pH is relatively common (example: pool and fish tank maintenance) and the equipment to do it is fairly accurate and readily available. Measuring ORP is another story entirely. ORP is expressed in millivolts (1/1000 of a single volt) and measures extremely slight, and highly variable differences in the electrical properties of water. Instruments that measure ORP range in price from $100 for a handheld “tester” to over $3,000 for more sophisticated laboratory equipment. Look for the more sophisticated and expensive laboratory equipment.
    • Solid lab protocols and flawless execution. There are many factors which can be manipulated easily in a video. Find out how this is done Here.
      You will want verify that all possible variables that could affect the outcome of testing were strictly controlled such as settings, flow rates, age of the ionizer.

  • Are the Results Certified? You want to see results certified by a credible authority, which will stand behind the fact that it is an Independent Third Party that has employed proper scientific protocols. The litmus test here is easy: would the certifying party have anything to lose if they were caught falsifying certified results? An analytical lab with an EPA certification on the line would be a good bet to provide facts that are verifiable and trustworthy. A guy standing in a kitchen would not.


A few simple questions make this easy. You should ask:

  • Who is making the rating or video?
  • Who actually performed the tests?
  • Is the person testing (and standing behind the results) credible? Can they be believed?
  • Would they have any motivation to skew the results?
  • Are they up-front about who they are and why exactly they are rating ionizers?
  • Can you see the setting level selected of each ionizer in each test?
  • Can you see the flow rate of each ionizer or the flow rates all running at the same time?
  • Are the results of the top brands similar or is there an unrealistic variance?


The other sites that offer their “comparisons” and “ratings” place far too much emphasis on performance. They ignore many important considerations such as flow rate (how fast you can fill up a quart or liter), durability (performance over the life of the unit), effectiveness of filtration, manufacturer and the type of service you will get after you purchase.
