12 Best Water Ionizers Review

1 Aqua Ionizer Deluxe 7.0

Aqua Ionizer Deluxe 7.0

The Aqua Ionizer 7.0 offers 7 water settings. We find many similarities between this model and the Aqua Ionizer 9.0. Both offer 7 water settings; 4 alkalines, 2 acidic and one neutral.

The Aqua Ionizer Deluxe 7.0 has a great pre-filter. Both are provided with top-quality filters that attack contaminants. The filter will need changing after 4000 liters that is nearly a year we calculated.

The Aqua 7.0 handles significantly less water. The adjustable pH and ORP values are where they should be for a good water ionizer.

pH range- 4.0 to 11.0

ORP range- +650 to -750 mV

It has 7 durable platinum-coated titanium plates, is self-cleaning and auto plate washing kicks in every 10.5 gallons. So if you are in the market for a self-cleaning unit, look no further.

You will have to part with close to $800 to get this model into your home. With a 5-year warranty, you have your family’s health covered and protect yourself financially.

The Aqua Ionizer Deluxe 7.0 surpassed our expectations. It’s jam-packed with features that actually perform. The auto plate cleaning is an addition that goes beyond just utility; it guarantees safe standards of clean alkaline drinking water.

Another small but useful feature is the backlit display screen makes viewing a lot easier.


  • Routine maintenance made easier with a self-cleaning feature
  • Seven water settings possible
  • The lifespan of an activated carbon filter is about a year
  • The service life of the long-life filters is 1 year
  • 7 titanium plates are added to this advanced electrolyte technology


  • Installation can be difficult

Our Verdict

We give it a thumbs up outright. Alright accepted it is not much as far as looks go. But once in a while, you review a product where you can see that the manufacturers have walked the extra mile to put together useful features to give you a high performing, durable machine.

The Aqua Ionizer Deluxe 7.0 qualifies for this badge in our opinion and worth every dollar you will be shelling out for it. It rightfully belongs to the top of our list.

2 Bawell Platinum Alkaline Water Ionizer Machine

Bawell Platinum Alkaline Water Ionizer Machine

It is important to manage the type of ionized water you are getting and the Bawell Platinum Ionizer is precisely designed as an effective electrolyzer for this. It is top-rated and has an impressive 5 power settings with each setting featuring 8 pre-programmed levels.

A dual internal filtration system is installed inside this ionizer that targets harmful contaminants including lead and mercury. This filtration system is darn good and can with ease process about 4000 liters of water.

What’s more, a voice prompt prods you when the filter needs to be replaced.

It has a self-cleaning feature but its performance falls short of that bundled with the Aqua Ionizer Deluxe 7.0.

The pH range that the Bawell offers is impressive and the ORP range is right there with the industry’s guidelines.

The pH range is adjustable and is from 2.0 to 12.0. The ORP range is +600 to -800 mV.

If you are desirous of getting a Bawell Ionizers you will need to peel open your wallet a bit. It will set you back $1500. Okay, the dual filter will last a couple of years so no costs will be incurred there. We say that considering its efficiency and durability in contaminant filtration, the price tag is insignificant.

Trust us on this. It provides ultraclean alkaline water for drinking and acidic water for household cleaning.

We forgot to mention, it comes with a lifetime warranty. It makes an excellent option for industrial use.

This machine is particularly suited for countertop installation so installation is a cinch and should take about 15 minutes.

The manufacturer has exhibited sufficient concern by opting for BPA-free plastic in the construction. That had us awed.


  • An internal filtration system of two stages
  • Optional 3 stage external filtration system
  • 1300 gallons/2-year cartridge filters that are durable
  • It can be readily hooked to the water line or faucet
  • The warranty is a lifetime
  • A continuous provision of alkaline drinking water that is pure
  • Ideal for countertop installation


  • Somewhat difficult to replace filters

Our Verdict

The team was kept busy asking questions and getting a feel of this advanced ionizing machine. We could only fault the self-cleaning system. Not that it underperforms, but only in comparison the Aqua Ionizer 7.0 is a tad better. It takes nothing away from the Bawell.

The feature we particularly found good was the flow rate; 30 seconds for a gallon. Yes, the price is high but we have not listed it under cons because we firmly hold ground that it is justifiable.

3 Life Ionizer MXL-9 Counter Top Alkaline Water Ionizer

Life Ionizer MXL-9 Counter Top Alkaline Water Ionizer

The MXL-9 is next-gen stuff. This ionizer of Matrix GRID-plate destroys the competition. It will prove impossible to match this pile-driver in water purity, performance or warranty. The awesome combination of 9 huge platinum-coated titanium plates teaming up with 500 watts of power pours out alkaline water of high strength. Irrespective of the pH of your water source, the MXL-9 is committed to providing you alkaline and acidic water of unmatched quality.

It is suitable for both countertop and under-counter installation.

The pH range is 2.0 to 11.5, a pretty good span.

The ORP range is -800, the antioxidant potential at the lowest end of the scale.

The manufacturers are evidently environmentally conscious in that all tubing is BPA-free.

The Life Ionizer has an advanced RDAC self-cleaning feature.

We absolutely loved its sleek looks; space-saving and the compactly designed machine is a show-off piece.

It is armed with practically the whole works; SMPS, UV for decimating bacteria and viruses, and hydrogen infusion too.

A lifetime warranty on parts accompanies this machine plus 10 years on labor. Nice deal.

We like it that the manufacturers refer to the process as electrodialysis and not electrolysis. Our consultant engineer put it in perspective for us. 5-micron carbon filters wipe out the chlorine taste and odor. A fluoride filter AR-100F removes all fluoride including what may have been added by municipalities. So, you don’t have to buy a separate fluoride water filter for this.

A faucet is provided with the unit. It has two spouts; the upper one gives you alkaline water and the lower one, acidic. You can choose your settings directly on the faucet itself.

At the time of writing this, this model was not available. It retails at $2400 to $2600. When we probed, we were referred to Life Ionizers the makers; it was available.


  • High-performance water ionization
  • Installable on the countertop or under the counter
  • Dual filters plus UV sterilization
  • Comes with a faucet and settings can be adjusted from the faucet itself
  • The remaining filter life is displayed on the screen.
  • ISO certified


  • Under the counter installation is a bit complicated

Our Verdict

Some might say it is too pricey. Well, look at the package of freebies, features, and warranty. This is a machine that is your lifetime friend. And you can sleep well knowing that you have given your family the best drinking water solution out there.

4 Aqua Ionizer Deluxe pH 5.0 – 11.0

Aqua Ionizer Deluxe pH 5.0 – 11.0

The Aqua Ionizer Deluxe pH 5.0-11.0 is more commonly known as the Aqua Ionizer Deluxe 5.0. It is a smaller unit that is pocket-friendly without skimping on too many features.

This machine has 7 water settings; 4 ionized alkaline, 2 acidic, and 1 non-ionized purified.

This ionizer gives you water at 4.5 to 11.0 pH which is a bit limited in our opinion. But having just 5 plates some compromises are necessary. The minimum ORP is higher at -600 mV and filter life shorter.

This is a great choice for you if your family is small, you do not need acidic water for household cleaning and cosmetic purposes.

It boasts a filter of activated carbon that removes impurities before the ionization process. This includes chlorine and chemicals that taint the water.

The filter works for 4000 liters before it needs to be replaced, which is about a year.

One of the drawbacks is that it does not work with well water and with any other source that contains harmful microorganisms. So if your only source is well water, you will need to install a filter that deals with well water to get rid of the TDS (total dissolved salts) first.


  • Affordable for all
  • Easy-to-use control panel
  • Takes up less space on the counter
  • Can be installed under the counter
  • Self-cleaning plates


  • Limited pH range
  • Higher ORP levels

Our Verdict

We are bound to provide a truthful account of the products we are to review. That this product made it to our list is because it is a performer, durable albeit some limitations. Despite being a relatively cheap water ionizer, it totally fulfills our needs; safe alkaline ionized water. No frills. So if you have a small family, or reside in a small apartment with restricted kitchen space and a budget, the Aqua Ionizer Deluxe 5.0 is your baby.

5 Tyent UCE-11 Under Counter Water Ionizer

Tyent UCE-11 Under Counter Water Ionizer

It is a high-end product and we have good reasons to put it as one of our top 5 choices. This is the Dame Judy Dench of ionizers. Power-packed performance and astounding durability. It comes at a cost but its features and versatility are unmatched. Try this:

  • 11 big plates
  • Low ORP levels up to -1050 mV
  • A pH scale between 2-12.
  • Two big filters that literally herd out contaminants so safe, ionized water results
  • A sensitive touch screen where you can get access to all settings
  • 7 settings; 3 alkaline levels
  • 3 acidic and 1 neutral pH level that is ideal for formulation of baby food and ingesting medicines
  • Under sink installation. Easy and DIY
  • 750 watts of power

The Tyent with its 11 plates, the most an ionizer has a straightforward indicator of efficiency performance. The more numerous  the plates, the quicker water generation is. Extra plates also accelerate the electrolysis process that results in lower ORP levels with pretty high levels of  hydrogen molecules.

With its high power, it is indeed turbo-charged with a powerful current being imparted to electrodes.

If you are wondering about your electricity bill at this stage, sit back and relax; a marvel like the Tyent UCE-11, of course, has an SMPS system which is energy-saving amongst other safeguards it offers.

Here we intervene with a strong recommendation. Like climbing Mount Everest, where you have to spend some time at higher levels getting acclimatized, so it is with alkaline ionized water. You start at level 1, get used to it and gradually up to level 3. Do not shock your body with an abrupt change.

There are tons more features that we’re leaving for you to explore.


  • Top-quality and all parts are top end
  • The filtration is pretty thorough. Removes 99.9% contaminants
  • Lifetime warranty
  • All components for installation included
  • Long filter life of 950 gallons
  • BPA free


  • Costly filter replacement
  • Cannot be used if electricity fails

Our Verdict

The Tyent UCE-11 is a boom box. It will clean itself which is nice; no need to open up and mess around manually, no wonder why it’s one of the best-rated models on our list. A bit disappointing is that the filters last about 6 months. Also, customer service is not timely, put us off a bit.

All said and done with a tag of $3400 is a far reach for many. But we do agree that given its features, performance, and durability, it’s worth the money.

6 Aqua Ionizer Deluxe 9.0

Aqua Ionizer Deluxe 9.0

Air Water Life, the manufacturers of the Aqua Ionizer Deluxe 9.0 are a company of repute in the field of ionizers. This list has three of their products. This model is one of their best-sellers. It is a high-end model without a high tag. It has an interesting set of features and options, of course, the bells and whistles are missing.

Its pH level range starts at 3.0 and goes up to 11.5.

The built-in filter of activated carbon will generate 4000 liters before replacement.

This 9 plate system yields 7 different types of water. The antioxidant potential is superb with an ORP as low as -860 mV.

One thing we noticed was that the Aqua 9.0 with 9 plates produced ionised water comparable to the MXL-9 at half the cost.

The plates are self-cleaning which keeps up the efficiency during ionization and prolongs the lifespan of the unit.

With settings that are 4 alkalines, 2 acidic and 1 neutral pH, it is serious competition to pricier models. Here the innovativeness and experience of Air Water Life show up.

Other ionizers have plain numbers for the water settings. The Aqua 9.0 has a mention of the use which is supremely user-friendly.

Cooking: 9.5-11.0 pH

Brewing coffee/ tea: 9.5-10.0 pH

Daily Drinking: 8.5-9.5 pH

Initial drinking (for people new to alkaline water): 7.5-8.5 pH

This machine does not remove harmful pathogens or TDS so it cannot tackle well water.


  • Great value- plenty of features and high performance for less money
  • Versatility- 7 water settings
  • Digital interface with essential readings
  • It can be installed on or under the counter
  • Water filter integrated with replacement reminder
  • Easy installation and maintenance


  • It has only a single activated carbon filter

Our Verdict

We really took a massive like at the intuitive labeling of the water setting levels. Other manufacturers should borrow a leaf from Air Water Life and follow suit. The Aqua 9.0 is convertible and can be mounted on or under the counter giving you greater flexibility in installation. It retails for around $1400, which is value for the money.

The bottom line is well suited for families looking for a high-performance ionizer which costs significantly less than a Tyent or Life ionizers.

7 Pure Hydration Next Generation by Cosan/USA

Pure Hydration Next Generation by Cosan/USA

The Pure Hydration Alkaline Antioxidant Water Ionizer is a natural ionizer. During our research, we gleaned that a natural ionizer though not as efficient as electric ionizers have their fair share of plus points. They give you quality alkaline ionized water with lots of molecular hydrogen that is antioxidant besides being economical, about one-fifth of pricier models.

It is pretty compact sized and is for countertop mounting but that doesn’t mean you can’t install it under the counter if that is what you prefer.

Don’t let the size fool you. It can do a lot with its four filters:

  • the cation resin filter softens the water like a quality water softener;
  • a carbon and silver block cartridge removes sediment, rust, chlorine, and other chemicals;
  • alkaline/ hydrogen infusing cartridge to increase alkalinity and pH, lower ORP and supplement molecular hydrogen increasing antioxidant levels;
  • Solid activated carbon with KDF (Kinetic Degradation Fluxion) mineral cartridge provides additional filtering followed by the addition of minerals to the water, the process of ionization.

Being a natural ionizer, it doesn’t quite match the performance of an electric ionizer. One of its pluses is that it is environmentally friendly.

The fallout of four filters which need replacement every six months is that maintenance costs are pumped up. The LED signals when the filters need replacements.


  • Installation is easy
  • The performance of water filtration is high
  • The alkaline water level of molecular hydrogen is high
  • Low ORP


  • No water setting options
  • Many filters to replace periodically

Our Verdict

The ideal description of the Pure Hydration Water Ionizer is an ‘ionizer and water filter’ and not just an ionizer. It’s priced in the range $330 to $350. In our opinion, at this price, the costs of changing filter cartridges are partially offset by zero power consumption. It is worth the little expense you will incur.

The other deficiency of no acidic water is not a setback at all. After all, cleaning water is not such a big deal.

8 LevelUpWay Glass Hydrogen Generator Water Bottle

LevelUpWay Glass Hydrogen Generator Water Bottle

We endorse that drinking water from an alkaline filtration system is quite beneficial to health.

If your hunt for an alkaline water generator is focussed on health and fitness, the LevelUpWay Glass Hydrogen Generator is what you want.

It employs a technology called SPE PEM having an Exchange Membrane that is an advancement than ionizers or other water generators.

This new technology and its benefits over ordinary outdated technology are manifold.

  • To reach a concentration that is 1100ppb, it just takes 6 minutes
  • Chlorine, Ozone and other pestilent substances are flushed out completely
  • It can be used for two to three years without any maintenance requirements
  • The water purity is unaffected by the Platinum Electrolysis Technology
  • The battery of lithium-polymer is of a long-life. It can be put to use over 20 times after charging

The merits of SPE PEM technology:

By-products such as O2, Cl3, and O3 are scrubbed clean during the water generation process. These pose unacceptable health issues.

SPE technology strips trapped oxygen from the water

The production of H2 is unconstrained by minerals in the water. To produce H2 sufficiently, high mineral quality is needed by ordinary ionizers.

The H2 concentration is greater than 1ppm which is high.

The electrolyte life is higher than in ordinary watermakers.

Premium quality:

Cholesterol is kept at bay thereby preventing arteries block promoting health. It contributes to antiaging.

This alkaline water generator averts LDL bad cholesterol and prevents blockage of arteries.

We were reasonably impressed with the water quality.

Best Alkaline Water Ionizer – Buying Guide

water ionizer machine

We have included this section as these are the parameters we’ve based our water ionizer reviews on.

1. pH Range

alkaline water ionizer

As earlier referred to, the scale is from 0-14, with 7 being neutral. A good example is plain drinking water.

Coffee, wine, cheese, meats, Coke, sugar, beer, tea, and alcohol are some examples of acidic foods that are less than pH7.

On neutral ground, at pH7 we can find butter, raw milk, and most tap waters. The realm of alkaline foods greater than pH7 is fruits, vegetables, and olive oil. Plan your food intake appropriately.

2. ORP Range

We are now aware of what ORP is. Oxygen reduction. Oxygen in the body does little good. It wreaks havoc on cells, proteins, DNA and what have you. That is why green tea and other antioxidants are perennially being touted. Oxidation is what causes rusting and an apple to go brown. This is achieved by stealing electrons or a negative charge. And who is the recipient of this theft; a free radical.

So we need to annihilate these little imps. How? Pump up on anti-oxidants or, lower the ORP. The yardstick of healthy water is low ORP levels. The unit of measurement is millivolts. The more negative, the better and that could be as low as -900 mV. -450 is considered reasonable.

3. The Configuration of Electrolysis Plates

The plates are the heart of an ionizer. The more upscale models use platinum-titanium. This is where the alkalinization process occurs. Needless to say, the better the plates the swifter and efficient is the conversion going to be. The rule-of-thumb dictates that the larger the number of plates, the better.

Expense too is scaled up. But the end product is very much superior, in terms of ionization strength whereby the pH range is larger as also the ORP. There are four configurations of plates:

  • GRID- Top quality with efficiency at its peak and matching durability
  • MESH- High quality and efficiency.
  • FLAT- Good quality and durability.
  • Slotted- Run of the mill stuff but mentioned here so you know.

4. Built-in Water Filter

Whoa! Before you jump on your horse and gallop off to the supermall to get yourself an ionizer, a couple of things more. This one is important.

A built-in water filter is a feature of all ionizers. In the event that your source is well water, you will need a model with a robust filter to cope easily with the water pressure. The filter would need renewal every 6-12 months which adds to your maintenance costs. This is speaking generally as it all depends on the manufacturer and model that catch your fancy.

5. Installation Process

This is usually a simple procedure but we don’t want you off guard on this one, so we think it is a worthwhile mention.

You are faced with three choices; countertop, under the counter and convertible.A countertop is a breeze. You don’t even require any tools.

Under the counter is a tad more challenging. Your user manual will guide you amply well how to go about this.

A convertible installation can swing both ways. An example would be the Life Ionizers MXL-7 or the Aqua Ionizer Deluxe 9.0 models which we will elaborate upon later.

6. Power

Modern water ionizer machines are shielded by an SMPS (Switched-mode Power Supply) power supply that is powerful and pretty efficient. Its chief function is to stabilize the voltage so that unwarranted fluctuations don’t damage the machine. Some machines like Kangen do not have this as they use older technology.

7. Auto-Cleaning Capacity

Some ionizers are equipped with a self-cleaning feature that kicks in after every use. Some have an automatic plate washing facility that is activated after ionization of a preset amount of water that varies from model to model.

8. Type

The main advantage of consuming hydrogen infused water is the high antioxidant content which destroys free radicals, the cause of much body damage.

Bottles- Bottles are portable, can be carried on walks and outings and not relying on river or pond waters. They can be taken along on travels, used at the gym and are very handy. On top of that, they are the cheapest options to get.

Pitchers- Pitches are good for family or office use. They are installed as a countertop but can be readily shifted into the refrigerator and you have cold, refreshing, hydrogenated water. These look a lot like water dispensers. Not a bad bargain.

Machines- These are fixed installations and are dealt with in detail.

9. UV Light

The UV light in your ionizer is to destroy bacteria and viruses.

10. Warranty

An important consideration. Mid-level and inexpensive models should offer at least a 10-year warranty. The plates being of prime materials should carry a life-term warranty. We wish to guide you that a warranty of 5-years or less is a clear indication that the manufacturer does not measure up.

The Benefits of Ionized Water

top rated water ionizers

Ionizers increase the pH of running water applying electrolysis and divide the incoming water flow into alkaline and acidic components.

This is a moot point, medically speaking.  The jury is still out on this. But that is not our concern. We will present both sides of the coin to you.

The pH level ranges from 1 to 14 with 1 being strongly acidic and 14, very alkaline. Tap water is at around 7; a bit of both.

The main focus of an ionizer is to nullify the acidic part as we all know what distress acidity or de-ionizing can cause.

A water ionizer is also called an alkaline ionizer as the pH level of an incoming stream is increased. It’s different from traditional water treatments using chemicals. This is accomplished by electrolysis wherein the water is charged negatively resulting in microclusters that have higher cellular penetration capacity. The acidic proportion is nullified.

The major benefits claimed:

  • Consuming artesian well water with a pH of 8.8, according to a study by the National Institute of Health, shuts off the enzyme pepsin, the chief culprit of acid reflux.
  • Another study by the Shanghai School of Preventive Medicine advises consuming ionized alkaline water benefits in the reduction of hypertension, diabetes and high cholesterol.
  • Yet another study, this time by the Journal of the International Society Of Sports Nutrition which concluded that post a workout, consuming alkaline water helped boost blood flow by lowering blood viscosity. Oxygen delivery is amplified.
  • Adherents are vociferous that alkaline water is anti-aging, colon cleansing, supports the immune system, is a powerful detoxification agent, and has cancer-resistant properties.

Now for the other part of the narrative.

Alkaline water can cause metabolic alkalosis. This is the result of excess alkalinity in the body. Alkalosis can deplete free calcium affecting bone health. Nausea, gastrointestinal complaints, vomiting, arm tremors, muscle twitching, and confusion are the fallouts.

Alkaline Water Filters Vs. Water Ionizers

water filter and ionizer

The ionization of water can be accomplished by two methods. The first is electric, a water ionizer that is based on the principle of electrolysis. The other is by using an ionizing filter that relies on the addition of minerals such as zeolite, magnesium, and tourmaline. Thereafter some form of magnets is deployed to lightly ionize.

Manufacturers hype it up that their product works better. This post will explain the similarities and differences between the two systems so you are on an even footing when it comes to deciding

Benefits of Electrolyzed Water Using a Water Ionizer

The basic model of an electric water ionizer is to split the acidic and alkaline parts. The upshot is an alkaline water stream rich in useful minerals (such as magnesium, calcium, magnesium) which are beneficial to the body. The acidic stream filters out the toxic elements (fluorides, chlorides).

We do not intend to make a boring, pedantic presentation, but there is a need to know what ORP (Oxidation Reduction Potential) is. It is the tendency to accept electrons or a negative charge. It is an antioxidant level measuring unit. In electric water ionizers, this level is pretty raised.

Benefits of Alkaline pH Ionizing Filters

These ionizing filter systems are quite inexpensive because they don’t include platinum plates that are used as electrodes in electric ionizers. The annoying bit is that they can only offer up a limited quantity of water before needing a break to recharge.

The reason, alkaline pH ionizing systems employ the principle of spontaneous ionization discovered by Dr. Hayashi, where the ionization is accomplished by the use of magnesium in a field of ceramic magnets.

For this, time-release magnesium balls are present in the filter. The outer layer of these balls is used up to ionize a certain quantity after which the balls need to recharge. A negative charge is only applied to the magnesium quotient in the water.

Our take is that electric water ionizers are more capable in that negatively charging the water makes it more bioavailable to the body. They are capable of stronger ionization as well as giving you an uninterrupted supply of drinking water. On top of that, you wouldn’t need a separate water dispenser if you have a full-size ionizer.

Do’s and Don’ts of Maintaining a Water Ionizer

Remember that cleaning an ionizer is not as simple as cleaning a water dispenser or a cooler. For the safety of the user as well as the machine, the undermentioned dos and don’ts will ensure that your water ionizer will give you peak performance and trouble-free service.


  • The internal filters of the machine need replacement every 6-12 months. This process will consume 5 minutes of your time. New replaced filters will need to be flushed for 2-5 minutes before they are installed in the machine.
  • Internal cleaning will need to be done regularly. For this, a cleaning cartridge is used or a process as defined by the manufacturer. This flushes out mold and bacteria build-up from hidden parts of the machine invisible to the eye.
  • Wipe down the machine with a soft cloth or sponge every week. The exterior is maintained and your water ionizer will sport a new fresh look.


  • The product manual lays down the cleaning protocols. If you have commenced cleaning with any other incompatible process, discontinue the cleaning process. These instructions may have been given to you by a friend or picked up on the web, or any other source but from the manufacturer.
  • Keep adequate time in hand once you have initiated the cleaning process to complete the job, it should be followed until the end. Even if you have a self-cleaning system in place, manual cleaning must be thorough to make sure that any bacteria build-up is wiped out.
  • Strictly avoid household cleaners on the ionizer. The finish will be damaged as well as eroding the control panel’s indicators.

Happy shopping!


 1. Is Ionized water safe to drink?

Ans. Certainly, ionized water is 100 % safe to drink. Only one must start at low levels first and work your way up.

2. How does the machine’s quality get affected by the automatic self-cleaning feature?

Ans. For better results even if you have an automatic self-cleaning system in your ionizer, periodically a manual cleaning is necessary to maintain the efficiency.

3. What does the ORP level or the oxidation-reduction potential indicate?

Ans. Simply put a high ORP level indicates a high level of oxygen and a low ORP level indicates a high level of hydrogen.

4. What is the function of a Water Ionizer?

Ans. A water ionizer raises the pH level of drinking water so that it is more alkaline.

5. Reverse Osmosis Vs Water Ionizer

Ans. All the minerals are removed by Reverse Osmosis and distillation rendering the water ‘dead.’ Ionization concentrates healthy minerals like magnesium and calcium and creates a higher alkaline water level.

6. Water Ionizer Work on what principle?

Ans. Water ionizers work by separating the water into two streams; acidic and alkaline by means of electrolysis. The two streams are treated differently resulting in alkaline water for consumption and acidic water for household cleaning.

7. What is the right way to Install a Water Ionizer?

Ans. A plumber is redundant here. Each unit comes with a simple to fit diverter kit along with instructions and can be completed in 5 minutes.

8. How Long Does Ionized Water Stay Ionized?

Ans. The antioxidant properties will dissipate after 18-24 hours. It takes 1-2 weeks for the pH value to return to a neutral value of 7.

9. Where to buy ionized water filters?

Ans. If you live in the US, we’d recommend Amazon for fast and reliable delivery.
