The Best Water Ionizer Reviews and Comparisons

Updated: April 16, 2021 by Zac Harding

Everyone knows that drinking plenty of water every day is key to optimum health, mental focus, and good digestion, however, we know sometimes people can be left wondering if there are other sources of hydration that have more benefits that are available to them.

Bottled water is great for reassurance that your drinking water is safe from debris or impurities and has extra minerals that can benefit your health.

However, continuously buying bottled water is not good for your bank account or the declining environment around us.

So you’re either stuck with possible contaminated water from your kitchen faucet or buying excessive quantities of bottled water in your weekly shop that then get chucked away straight after.

Not for much longer though. We’ve found the solution to this massive issue and that’s through the use of a water ionizer, which not only removes impurities from your tap water but also converts the water to become more alkaline so it has additional health benefits to regular water.

Water ionizers will save you money from having to buy bottled water all the time and will allow you to always have clean alkaline water right from your kitchen.

If you’re new to water ionizers then trying to narrow down the right one for you can be overwhelming, that’s why we’ve searched high and low to bring you the best water ionizers out there right now.

What Is Ionized Water?

The Differences of Alkaline water and Regular Water

Alkaline water has a higher level of pH than regular drinking water from the tap. Alkaline water contains more minerals and can neutralize the acid in the body.

What Are the Benefits of Drinking Ionized Water?

The benefits of drinking ionized water are still speculated by both consumers and scientists in the field. Ionized water does have lots of antioxidant properties.

Even though scientific research behind the benefits of ionized water is inconclusive as of right now, it is believed that it can boost the immune system, benefits weight loss, has colon cleansing properties, and can also improve the health, and appearance of your skin.

Is It Safe to Use Water Ionizers?

Water ionizers are generally considered safe to use for frequent consumption of ionized water, it is only the health benefits behind it that are still being speculated.

Ionizer water or alkaline water, if over consumed or consumed when the pH level is too high can cause nausea, confusion, and even vomiting. Drinking too much alkaline water can make you deficient in other minerals as well.

How Does a Water Ionizer work?

From the off, water ionizers can look overly complicated and difficult to use and understand, however, they’re pretty simple to learn about how they work.

Water ionizers are commonly attached to the water supply in your kitchen, this way the unit will be able to work directly with your tap water to produce alkaline water.

The tap water flows to your water ionizer unit specifically across the plates, where it then gets converted and separated from the acidic minerals and turned into more alkaline minerals. Both these streams of water are released in two separate streams.

What to Look For in the Best Water Ionizers

pH Range

If you’re looking to buy a water ionizer then it’s probably because of its ability to produce ionized water (or alkaline water).

Whilst this may be the primary use, it may still be able to produce a large range of pH water, which is not just limited to alkaline. The most alkaline pH stands at 14, whilst the most acidic pH is at 1. pH 7 would be neutral and is around about the average of regular tap water.

A water ionizer that has a big pH range will give your more flexibility in how you use it. Low pH water is best used for cleaning around your home, but drinking water that is less than pH 6.5 is considered pretty dangerous to your health and could also corrode and leach metal.

More alkaline water is considered beneficial to our health and can be drunk daily and used for cooking purposes, like boiling pasta or rice.

However, drinking water that has a very high pH e.g over pH 11.5 can cause gastrointestinal and skin problems, as it agitates the body’s normal pH and causes metabolic alkalosis which can also lead to nausea.

If you were just buying a water ionizer for the alkaline properties, then you won’t need to focus too much on the pH range incorporated in the machine.

Number of Plates

You would’ve already come across a discussion about the plates inside a water ionizer in the discussion about how a water ionizer works, but here we’ll go more in-depth to why the number of plates plays such a central role in how well a water ionizer works.

The plates in the machine are how the water will turn from more acidic or neutral to alkaline or ionized water. It’s important to know the material that these plates are made out of as they come into direct contact with your drinking water. The best material for these plates is normally coated titanium, which is of a very high-quality and highly effective in converting the water to become more alkaline.

You’ll want to try and find a water ionizer that has the highest number of plates possible as they’ll produce more power and be more effective in achieving a higher level of pH and will have a greater OPR range.

Generally, the higher number of plates in a water ionizer will result in a higher price tag as the cost of producing and manufacturing these plates inside the machine can be very high. More affordable models will come with 5-6 plates, whereas the more expensive models will come with 10+.

Units with high numbers of plates will consume more power and therefore not only cost more initially but also add more to your utility bills. However, if you do want a reliable and effective water ionizer, then go for a water ionizer with a high number of plates and check the material they’re made of.

ORP Range

OPR range stands for oxidation-reduction potential, this refers to the cleanliness of the water and its ability to break down contaminants. The lower the OPR, the healthier the water is for you as it lowers the level of oxidation that occurs in the body when you drink it.

Oxidation in the body damages cells and DNA and works by taking out the electrons from a substance. What replaces these electrons is known as free radicals.

Ionized water works the same as antioxidant substances and restricts the free radicals from damaging your body and making you more prone to developing diseases.

Therefore, finding a water ionizing machine with a low OPR range is imperative as it makes it much safer and beneficial for you to drink.

Built-In Water Filter

A good built-in water filter will be a factor you want to consider when looking to buy a water ionizer. Which means you don’t need a separate water filter to purify your water. An efficient filter will be able to remove contamination from the water before it gets ionized. Some water ionizers will offer a multi-stage filtration system.

Look out for water ionizers that say they have a strong enough water filter to remove chlorine, lead, chloramines, volatile organic compounds, and trace detergent residue. These are the main things you want to be removed from your water before it gets ionized.

The water filter will need replacing after 6-12 months, depending on the type of water you have in your area. The price of these water filters will depend on the brand of water ionizer that you have. You’ll want to take into consideration the maintenance cost of your water filter when buying a water ionizer.

Certifications

Some water ionizers will come with certification from international organizations and government agencies that have professionally recommended the product for its high-quality construction and effectiveness.

Some of these organizations could include, European Conformity (CE), American National Standards Institute (ANSI), and Good Manufacturing Process (GMP).

Installation Process

Before spending lots of money on a high-tech water ionizer, think about whether you’re able to set it up and install it in your home. There’s not too much to it and most good water ionizers will come with detailed instructions on how to get it working properly.

Countertop units are a lot more simple to install, they often only require a few steps and no tools at all. However, under the sink units are a little bit more complicated and can be more fiddly, requiring some patience. There are plenty of YouTube videos online to help you install your water ionizer properly.

Countertop vs Under-The-Counter Unit

Water ionizers are available in countertop and under-the-counter units, so if you’re restricted on space in your kitchen, an under-the-counter unit would be better suited for you.

Countertop water ionizers are often designed to be more stylish as they will always be displayed out on the kitchen counter. The countertop units are much more convenient for monitoring the pH and water data within the machine as you won’t have to duck under the sink to take a look.

If you’d prefer your water ionizer to be completely out of sight, then go for an under-the-counter option.

Warranty

From reading this article you may have come to a general conclusion that water ionizers don’t come particularly cheap. Some are a real investment and spending that much money on a water ionizer is enough to turn someone’s stomach sick.

Try to find a generous warranty, especially if your water ionizer is expensive. A warranty will help cover any manufacturing damages or faults that occur during your initial period of owning the new product, this will hopefully get you a refund or at least a brand new replacement free of cost.

Water Ionizer Maintenance

How to Know When Your Water Ionizer Needs Maintenance

Several signs will determine if your water ionizer needs some maintenance or deep cleaning.

The most obvious sign will be that your water ionizer has failed to work completely, which is normally caused by a build-up of calcium or other properties in the pipes and plates. This issue normally occurs in areas where there is hard water.

If your water ionizer is not producing alkaline water with a low enough OPR (around the -200 to -400 range) then you’ll need to look into repair or replacing certain parts in your machine.

A low negative OPR range is important as that is what produces the health benefits of ionized water. You should monitor your OPR levels on the monitor on your water ionizer.

If your water ionizer is not producing small hydrogen bubbles in your drink, then it’s a sign that it is not working effectively or the machine needs to be cleaned.

An evident sign is that your water will taste unusual and often sour, this could be a result of the water filter needs changing or an issue that has come apparent in the machine itself.

If your pH levels in your water ionizer start to lower or there are frequent fluctuations in the pH levels, this is more common in water ionizers that don’t have a built-in filtering system.

If you can’t monitor or view the pH levels on a display on your machine then you can purchase a pH testing kit that will allow you to find out what pH your water is currently at.

How to Know When A Water Filter In a Water Ionizer Needs Changing

There are 3 main signs to look out for that will signify when your water ionizer needs changing, these signs are related to the water filtration system.

The first indication will be that there will be an unfamiliar or unpleasant smell coming from the water itself or the water ionizer. This is caused because the water hasn’t been properly filtered due to it being clogged or dirty.

This issue can be easily solved by replacing the water filter, repairing any parts that need fixing, or if this is exceptional damage, the whole system will need to be replaced.

The next sign that will be easy to notice is that there will be debris or floating stuff in your water when you use the machine, this is caused by improper functioning of the water filtration system. Seek to replace your water filter as soon as possible if this occurs and avoid drinking the water entirely until the issue has been resolved.

One other sign to keep an eye out for is strange sounds. When the water filter needs replacing or is starting to struggle, it’ll sound like it’s straining or loud gurgling noises.

If the filtration system is not already broken, then try and get a replacement as soon as possible before it suddenly dies on you.

Maintaining Your Water Ionizer: Do’s and Don’ts

Do’s:

  • Replace the internal filters in your water ionizer every 6-12 months and flush out all the replacement filters for 5 minutes after you have changed them.
  • Wipe down the outside of your machine with a damp sponge every so often to prevent the build-up of grime or dust which could move inside the machine.
  • Use a cleaning cartridge every so often in your machine, to remove the build-up of bacteria or mold that you are not able to see. This procedure may differ from brand to brand, so make sure you read a manual or contact the manufacturer to see how you should stay on top of maintaining your machine.

Don’ts:

  • Don’t clean your machine without consulting with the manufacturer or manufacturing handbook beforehand. Improper or ineffective cleaning can result in the unit being damaged or breaking down entirely.
  • Do not use everyday household cleaning products to clean your machine internally or externally.

Cleaning Instructions For a Water Ionizer

Here are some general guidelines for you to follow when cleaning your water ionizer, these protocols may vary depending on the brand and build of your water ionizer unit.

  1. Remove your water ionizer filter from the unit. If your machine comes with 2 filters then only remove one of them
  2. Insert your cleaning filter into the space where your water ionizer filter is located
  3. Run your machine how you would if you were trying to use neutral water for around 5 minutes (Those who have countertop units will need to place both hoses into a cup or bowl and leave running until they’re submerged in water)
  4. Leave your unit unused for around 3 hours (Countertop models will require the hoses to be returned to their normal position by the sink)
  5. Remove the cleaning filter and put your water ionizer filter back into position
  6. Flush out the system again by running the system for another 5 minutes
  7. Monitor the pH levels of the water until it returns to an alkaline level

You should try and do this process at least once a year to prolong the life of your water ionizer.

Frequently Asked Questions

How long does ionized water stay ionized?

Ionizer water will last open in the air for around 1 to 2 hours.

When ionized water is stored in an airtight glass or container, the alkaline properties can be retained for 1-2 weeks, but you will get the most benefits from the properties within the first 3 days of ionizing it.

The antioxidant properties (hydroxyl ions) last about 24 hours.

What should I store my ionizer water in?

The best storage solution for ionized water is a vacuum stainless bottle that is double insulated. A glass material container will also retain the beneficial properties of ionized water to a good degree.

You should avoid putting ionized water into a container that has a flip-top lid, as the gas can easily escape through the gaps in the lid.

Is it better to drink regular tap water or ionized water that is days old?

It is still better to drink ionized water that is days old as it has been filtered, the pH is better and the OPR is also a lot better than regular tap water.

However, if you’re going to go through the effort of ionizing your water then you should try and drink it as soon as possible to reap the full benefits.

Why are water ionizers so expensive?

The coated plates or the electrodes, which ionize the water are pretty expensive and drive up the cost a lot.

The machines are scientifically developed by experts and the researchers who pitch the idea to manufacturers do not receive money or grants for their research.
