How to Shop for a Water Ionizer

There are many factors to consider when choosing a water ionizer, and a lot of misinformation and outrageous claims exist on the Internet. This guide will help you navigate the (alkaline) waters so that you can find the machine that is right for you.

    Understand that all electric ionizers will produce three types of water: alkaline ionized, purified or filtered, and ionized acidic, regardless of model, design, brand, or price point.

    Decide if you would like a countertop, undercounter or convertable model. Undercounter models are typically more expensive and more difficult to install, however they take up less space.

  3. Decide which features are important to you. The main difference between each ionizer is that it has either 3, 5, 7, 8, 9 or 11 ionization plates which effects the flow rate and pH ranges. All the other functions and bells and whistles are a matter of preference.
  4. If you plan to use ionized acidic water for disinfecting on contact, you will need a machine that can produce 2.7 pH water in your water source. This can be difficult if you live in a soft water area, as not all machines can make strong acid water under those conditions without chemical alteration.
  5. Do your research. Make sure the company you are ordering from has a good reputation, certifications and a solid warranty and return policy.

    Don’t forget to purchase a pre-filter. No onboard ionization filter addresses all chemicals and contaminants out there, so prefilters are necessary for optimal drinking water regardless of which brand you choose.


  • If you have a reverse osmosis system installed, you will need a remineralizer, since water ionizers rely on alkaline minerals in the water in order to ionize the water.
  • If you live in a hard water area, consider purchasing ionizer armor or a salt-free water softener ¬†which will help extend the life of your ionizer and protect it from scale buildup.
  • Explore and try the many uses of ionized acidic water in order to make the most of your investment – it can literally replace your household cleaning products by 50% as well as supplement many skin, body and hair care products.
  • Consider becoming a dealer, distributor or affiliate of the brand you choose in order to make an even greater return on your investment.


  • Beware of ionizer review sites. They are biased because they are owned by specific water ionizer brands that will steer you towards their particular brand and they also give themselves awards.
  • Beware of non-electric “ionizers.” The key to ionization is electricity, and while non-electrics are able to make minor changes to the water like altering the pH by two points, they are nowhere near as effective as electric ionizers and many use harmful resins as their filtration media.
  • Don’t pay more than you should–the top priced ionizers cost about twice as much as the other brands soley due to MLM (multi-level marketing) not because they have a better product.
  • Make sure the brand you are buying from does not use calcium sulfite in their onboard filters, or require chemicals to make strong acid water, as these chemicals can leach into your water and be harmful to your health.
  • Mesh and slotted ionization plates and UV light technology on an ionizer are just a marketing ploys to get you to spend more money.
