The 7 Best Water Ionizer in 2023

We live in an advanced world where we don’t have easy access to pure drinking water, unlike our ancestors. Millions of people in the US don’t have access to safe drinking water. If the trend of industrialization continues, by the end of 2025, we might be living in a water-stressed area, says WHO.

In this regard, a water ionizer becomes a must-have accessory for every home. 

A water/alkaline ionizer is a home appliance that can raise the pH of drinking water. It uses electrolysis to separate the acidic and alkaline components of the incoming water. The acidic components are flushed out, and the alkaline articles are stored in the water.

Regular water is different from alkaline water because of its lower pH. Alkaline water has a pH of 8 or 9 while normal water has a pH of 7. However, pH alone cannot attribute to the alkalinity of the water. It must also contain negative ORP and some alkaline minerals. The more negative the ORP( Oxidation Reduction Potential), the more anti-oxidizing it is. 

Benefits of alkaline water

The significant benefits of drinking alkaline water daily are not supported by concrete medical proofs yet. Still, many people have claimed visible improvement in their overall health after they started drinking alkaline water. Here are some commonly discussed benefits of alkaline water for the body-

  • The high pH levels of the alkaline water can reduce or stop the acid reflux. It can lead to increased oxygen levels in the bloodstream. You won’t be feeling bloated anymore and feel more energetic with improved metabolism.
  • It helps to get rid of the accumulated waste fast in the colon. If you often feel constipated, drinking alkaline water daily might help.
  • The antioxidant properties can rejuvenate your skin by improving the acid-base balance. Your skin will look more hydrated and plump. It also helps in lubricating the joints and muscles to some extent, thus limiting muscle fatigue. You can now workout longer.
  • Alkaline water helps in better detoxification of the body. It raises the pH level of the urine and improves kidney functioning. So you flush out toxins from your body faster.
  • Regular intake can boost immunity and provide long-term health benefits. As alkaline water naturally neutralizes free radicals, your body will not get affected by unwanted entities easily.
  • You can lose weight by drinking alkaline water daily as it neutralizes the body’s acidity. This means your metabolism will boost and you won’t gain weight as you did before.
  • The body absorbs alkaline water faster than regular water. So you feel more hydrated all day long. It is beneficial for people with chronic dehydration, especially.

What to look for while buying a water ionizer?

No matter how impressive or expensive your water ionizer is, all that matters the most is your water quality. Ensure that you have access to the cleanest and safest drinking water possible before it is hooked to your machine. After that, you can traverse through these essential features to invest in a good water ionizer.

Convertible, Under Counter, or Countertop

The convertible variant is the most versatile as you can place it wherever you want. But it is slightly expensive. Choose as per the space available- counter one for limited space and countertop for a bigger space. Although it’s not hard to install a water ionizer, the countertop is the easiest one to install and use.

pH value adjuster

pH value adjuster

The ideal pH value is 8.5, where the water just turns alkaline. The lower the pH value, the more disinfecting and corrosive its properties become. This kind of water is right for cleaning. So choose an ionizer that has an easy control setting. You can adjust the pH value depending on your tasks- drinking, cooking or cleaning.



There are four types of plates available as of now- Grid, Mesh, Flat, and Slotted. The leaves help in the ionizing process, so you must choose the right one. Go for the flat, solid plates as they are generally better than the mesh and slotted plates. They are more durable and easy to clean. The other ones are lightweight and cheaper but won’t last long. 

The grid variety is the best you can invest in. That will increase your filtration system’s longevity. However, keep in mind the usefulness of the water ionizer ends at around seven plates. More plates won’t guarantee better functioning, and the opposite will not give the desired results. 


Always choose machines with two filters at least – even better if with a pre-filter. It will ensure an optimal level of drinking water comes out irrespective of your source. Look out for longer cartridges and ceramic profiles. Longer cartridges give better filtration and ceramic is effective against microbial cysts, protozoa, and bacteria.

 UV Light and Power

If possible, choose a machine with a UV light feature. It will ionize and purify your water simultaneously. The UV light can get rid of any virus or bacteria in the water. The SMPS power supply is efficient and powerful. Every modern machine should have it; however, don’t lose on this feature to get a cheaper variety. You will eventually spend more on repair charges.

Poisonous chemical

Some machines use chemical enhancers to get very high and low pH levels of water faster. These chemicals are Sodium Chloride which is common salt and Sodium hypochlorite, which is a bleaching agent. If a manual says their device releases chlorine gas then do not install it in an unventilated room as it is highly toxic. Please prefer another brand’s machine. Although, they claim that chlorine gas won’t go into the water chamber but why take the risk?


Warranty is essential if you want to spend so much money on a water ionizer. Ideally, it should have at least a ten years warranty on its plates and a lifetime guarantee. If it is less than five, give it a go. Here are a few things that will help you recognize a reputable company-

  • The company ISO 9000 certification (Factory compliance testing)
  • Minimum 5-year warranty on repairs and parts
  • Certifications for product quality (BPA free plastics, EPA approved, etc.)
  • Ratings of customer services
  • Company Associations (BBB, Water Quality Association, etc.)

Country of Origin

It may never cross your mind while buying a water ionizer, but your purchase decisions influence the life of you as well as million others on a daily basis. In this regard, choose the machine from a country that always abides by minimum wage laws, strict labor laws, and safe working conditions. Most countries don’t follow the regulations strictly. They can even use corrosive metals that will eventually damage the machine and our health. So do enough market research. 

Self- Cleaning

Some water ionizers auto-clean themselves when turned off. This feature is convenient for busy people and prevents calcium deposits on the plates as well. If you live in an area with hard water, this feature will keep the plates clean. Even during voltage fluctuations, the self-cleaning feature will put a minimum strain on the device avoiding any internal damage.

Beware of scams

Some companies might try to sell you an ionizer with more plates. It’s not guaranteed to provide better results but will cost you more. The truth is a seven-plate model will give you optimal results. Many companies also do negative campaigning for titanium and platinum poisoning. It’s a marketing tactic to sell you medical-grade products at a higher price which you should not fall for in the first place.

1. Is It Safe To Use a Water Ionizer?

There is limited medical evidence to validate the efficacy of alkaline water health benefits. But it is commonly agreed that if the source water is rich in sufficient nutrients and devoid of any impurities then the alkalinity will enhance the absorption and utility of water. A water ionizer is safe to use as it doesn’t add anything extra or harmful to the water just changes its pH value.

2. How Long Does Ionized Water Stay Ionized?

Ordinarily, the dissipation of the ionized water’s antioxidant properties will occur within 18- 24 hours. The pH level is also likely to drop in 3 hours. However, the alkaline water can retain its properties for at least a week if stored properly.

3. How To Install a Water Ionizer The Right Way?

There are several steps to follow especially in the case of under-counter units. First, you need to connect the waterline directly with the machine. You might need to uninstall the sink if necessary. Second, you need to pay attention to the faucet converter, a metal tube attached to the unit, and hoses’ connection. Finally, you can reposition everything by following the instructions from the product manual.

4. How Does Alkaline Water Taste?

Alkaline water will taste different than your regular tap water. Some advertise it to taste like artesian spring water with a smooth and delicate taste. It is due to the presence of certain minerals. Pure alkaline water might taste a bit bitter. It will change the taste of your regular tea and coffee.
