Now, let’s go through my comprehensive 2019 water ionizer buyer’s guide. Since I know you’re serious about buying the best water ionizer for your home, it’s important to read over all the information below.

I explain how to make ionized water, how oxidation reduction potential (ORP) relates to water quality, share my best alkaline water machine picks, and other water ionizer benefits to consider before purchasing your own.

Best Alkaline Water Machine: 2019 Buyer’s Guide

Water Ionizer Filter Considerations

I concluded through my research that water ionizers with a single filter may require pre-filtration depending on the quality of your municipal water.

If you have hard tap or well water, consider installing a 3-stage water filter system before your ionizer. This combination is the best alkaline water system for avoiding calcium buildup inside your ionizer.

When you install a 3-stage water filtration system, you extend the life of your water ionizer filters and avoid mineral buildup on the platinum-coated titanium electrode plates inside the machine.

Chanson’s Violet ionizer is one of the best single-filter alkaline water machines. The silver-impregnated carbon in the Chanson filter is a unique feature not offered by most water ionizers. Silver has proven antibacterial properties. Chanson also uses food-grade activated carbon that’s more absorbent because of its larger surface area.

Air Water Life’s Aqua Deluxe ionizers all use the same activated carbon water filter. The Air Water Life replacement filter costs less, but as I mentioned earlier, it’s important to consider installing a water pre-filter or whole water filter inline before a single-filter water ionizer.

If you already installed a whole house water filter or sediment water filter in your home, you should be good to go.

The Cosan/USA Pure Hydration alkaline water machine has the most expensive filters, but it does an incredible job of purifying tap water with its 4-stage water filter. If you want to see how cutting edge the Cosan Life Water ionizer is, read my full Cosan Water Review.

With the Cosan water ionizer, you don’t need to install a water pre-filter because the four-stage water filter takes care of all your water purification needs in one swoop.

The powerful Tyent UCE-11 filters have .01 micron filtration, which is the same level kidney dialysis machines use.

Should you use a reverse osmosis water filtration system with your water ionizer?

It’s important to remember that reverse osmosis filtration strips all the minerals from your water. For your water ionizer to function properly, you need to have some minerals in your feed water.

TIP: The titanium electrode plates in your alkaline water machine can’t conduct an electric current when your feed water has a TDS (total dissolved solids) of zero. Avoid using plain reverses osmosis water or distilled water in your ionizer.

If you already own a reverse osmosis filtration system and want to pair it with your water ionizer, there’s an easy fix. To make the alkaline water system work, all you have to do is install an inline remineralization cartridge between your RO system and your water ionizer or purchase an RO system with remineralization.

Click Here to read more about a reverse osmosis system with remineralization that I recommend at Amazon or click here to view an inline remineralization cartridge.

Do alkaline water machines work with well water?

Several people with well water reported that well water is compatible with their water ionizers.

However, it’s best to test well water first because you made need to use a water softener or install a water pre-filter that removes heavy metals.

Alkaline Water Machine Warranties

It’s no coincidence that the best alkaline water machine brands offer the best alkaline water machine warranties. All the water ionizers featured in this guide are manufactured by trustworthy companies.

During my research, I came across several water ionizer brands that appeared suspect with negative customer reviews. You won’t find any of those alkaline water machine brands here.

Air Water Life is one of the most trustworthy budget alkaline water machine brands, and their customer service team has high marks.Best Alkaline Water Ionizer Machines

It’s vital to do business with transparent companies when buying a water ionizer.

I had the opportunity to visit a Chanson Water store while I was living in Taiwan, and I can say without a doubt that they’re a legit company. They may not offer the same lifetime warranty as several other alkaline water machine brands, but the technology they offer is certainly state of the art.

Cosan/USA stands behind its Pure Hydration alkaline water machine with a 15-day money-back guarantee. You can essentially try before you buy.

Tyent's ionizers all come with a no-questions-asked lifetime warranty.

All the ionizers in my list of top 10 best alkaline water machines give you your money’s worth. Whether you want the lifetime warranty as an added bonus is up to you. I recommend the lifetime warranty when purchasing the most expensive water ionizers.

TIP: The alkaline water machine brands that don’t offer lifetime warranties may still help you after the warranty period ends if the problem is due to a product defect. There isn’t one company included here that doesn’t have great customer service. They’re on your side when you buy from them.

What does negative ORP mean?

If you’re new to alkaline ionized water, you may be wondering what ORP is. Did you notice that the most expensive ionizers with more titanium plates produce higher maximum negative ORP values?

Leading Asian researchers believe ORP is more important than water pH, and so do I.

Yes, alkaline water helps neutralize harmful acidity, but a negative ORP is what makes most of the alkaline ionized water benefits.

ORP is a measure of the antioxidant potential of the ionized water. The higher the negative ORP, the more antioxidants you get in every glass of water you drink.

Antioxidants are where all those great anti-aging benefits lie.

You’ve seen how an apple turns brown after its been cut or how metal rusts after sitting in the open air long enough. These are the effects of oxidation.

Antioxidants protect our bodies against the harmful effects of oxidation.

What is ORP?

ORP stands for “Oxidation Reduction Potential.” Alkaline water machines produce an electric current in the platinum-coated titanium electrode plates to make ionized water with a higher negative ORP.

Water with negative ORP is easier for our bodies to absorb, and this is the reason ionized water does a better job of keeping us hydrated than plain tap water.Best Alkaline Water Ionizer Machines ORP

We all know that chronic dehydration leads to serious health problems and illnesses.

Ionized water with negative ORP assists oxygen production in the body. People who drink alkaline ionized water – including myself – often experience an energy boost after drinking it.

Picture the ORP as the level of potential health benefits in your water. When the negative ORP is higher, there’s more energy packed in your water.

When you drink alkaline antioxidant water throughout the day, you get an around the clock energy boost.

The problem with positive ORP water

When you drink positive ORP water, it has an oxidizing effect on your body. This effect speeds up the aging process.

Guess what?

Tap water typically has an ORP between +200 and +600.

By drinking alkaline antioxidant water, you shield yourself from oxidative damage caused by positive ORP water. Antioxidants seek out harmful free radicals in your body and stop them dead in their tracks.

Antioxidant protection is the reason an immune system boost is one of the many health benefits of drinking alkaline ionized water.

If you’re anything like me and like to test things to ensure they’re working properly, use an ORP meter to test the ORP of your ionized water.

A handful of the best water ionizers on my top 10 list come with free pH test kits. Once you test the ORP and pH, you’ll know your ionizer is living up to your expectations.

Remember to test your feed water first to compare the results with your alkaline ionized water.

The Best Water Ionizer Flow Rate

When you purchase an alkaline water machine, the flow rate is more important if you intend to use the ionizer for commercial purposes. For singles, couples, and small families, the flow rate isn’t a key consideration.

As long as you have enough water pressure to get a steady stream from your water ionizer, you’re all good.


alkaline water machine flow rateYou want to optimize your flow rate to ensure your tap water comes into contact with the electrode plates for a sufficient period.

Most people don’t open the water tap all the way to reduce the flow rate. This way, the water is in contact with the plates for a longer period.

The surface of the plates is where the real magic happens. That’s why the most expensive water ionizers have the most plates.

As I mentioned earlier, Chanson’s electrode plate technology is some of the best on the market. The Chanson Violet may have fewer plates, but Chanson’s unique design increases the surface area of their plates to make ionized water with a lower negative ORP.

Why do top-rated water ionizers all use platinum and titanium electrode plates?

The reason all top rated water ionizers use platinum and titanium is that those metals are most resistant to corrosion and oxidation. The plates are constantly in contact with water with various pH levels, so they must be able to withstand that constant stress.

The platinum and titanium metals are the reason the best alkaline water machine brands offer lifetime warranties. The electrodes are built to last a lifetime. All the ionizers included here have titanium plates that were dipped in platinum.

Tyent’s and Chanson’s electrode plates are the highest quality.

Why is the number of electrode plates important?

The key to making ionized water with a higher negative ORP lies in the effective surface area of the plates.

More plates = More Surface Area

Since the water stays in contact with the plates for a short period, it’s necessary to make the most out of that time.

The metal plates create a current in your feed water. When you drink the alkaline ionized water from your ionizer, you drink water that’s been safely charged.

How do alkaline water machines work?

In nature, there’s a source of amazingly healthy alkaline antioxidant water – glacial water. We’re recreating glacial water in our homes with alkaline water machines.

When your tap water enters your water ionizer, it’s first filtered to remove impurities. Then it enters the ionization chamber with the electrode plates to undergo electrolysis.

Electrolysis safely produces alkaline ionized water and acidic ionized water. The water that comes out of your water ionizer hose is the alkaline ionized water.

If you’re a science geek like me, check out the video below to see how electrolysis works:

Air Water Life put together a helpful diagram below. It shows you what happens to your water during the electrodialysis process:

Acidic Water Benefits

What are the benefits of acidic water? A lot of people forget that one of the greatest water ionizer benefits is the ability to make acidic water.

Acidic water has many uses, just be sure not to drink it.

Acidic water with a low pH between 2.5 and 4 is great for household cleaning because of its natural antiseptic properties. These antiseptic properties also make it ideal for cleaning minor cuts and abrasions.

Low pH water also possesses natural antibacterial properties.

You save money by using acidic water to clean your home. Plus, you avoid bringing chemical household cleaners into your home.

Water with a pH of 5.5 is good for cosmetic use, moisturizing, and watering common varieties of houseplants.

Acidic water health benefits:

  • Many water ionizer owners have found acne relief by applying acidic water to it.
  • One woman’s husband used acidic water to clear a case of adult acne that had been bothering him for decades.
  • Another woman’s husband, who is diabetic, saved his infected toe by soaking it in acidic water after doctors wanted to amputate it!

Alkaline Water Safety Precautions

When you purchase your new alkaline water machine, you will surely be excited to boost your family’s health starting on day one.

However, there is an important rule to follow.

When you first begin drinking alkaline water be sure to start slowly.

The last thing you want to do is shock your body by drinking water with too high of a pH.

Keep in mind that the water you’ve consumed for most if not all of your life has a slightly acidic pH.

Alkaline Water Drinking Guide

What is the best pH level for drinking water?

This is the question many people ask when they first begin using their machine.

The best pH for first-time alkaline water drinkers is 8.5.

You will begin to notice an improvement in your health by drinking water with a pH of 8.5.

Your body will also receive the vital alkaline minerals it needs while getting a large dose of antioxidant benefits.

Another important consideration for all the parents out there is the health of your children.

Chanson recommends a water pH of 8.5 for children.

When to Drink pH 9.0 Water

Once your body has adjusted to drinking alkaline water, you can move up to pH 9.0 water.

Water with a pH of 9.0 is also great to drink after working out to reduce soreness in the muscles.

After a hard workout, lactic acid can build up in the muscles.

Water with a pH of 9.0 can reduce the negative effects of lactic acid in the muscles.

Aside from drinking 9.0 water, you can also cook with it.

Why is 9.5 pH water good for you?

There is a lot of talk about the health benefits of pH 9.5 water.

It’s actually the most talked about pH level among health enthusiasts.

You may be wondering why?

Well, once your body has adjusted to alkaline 9.0 water, you’ve already done some deep cleansing in your body.

Eventually, you’ll be ready to take the next to step to pH 9.5 water.

When you begin drinking pH 9.5 water, you will be getting a ton of antioxidants which leads to cell rejuvenation.

Water with a pH of 9.5 helps people heal from chronic illnesses.

If you suffer from chronic fatigue or tiredness, you will get a major energy boost at pH 9.5.

What is water above pH 9.5 used for?

Water with a pH of 11 or higher is good for cleaning dishes, stain removal, and washing fruits or vegetables.

I’ve read reports written by people who stopped buying organic produce and began cleaning their fruits with alkaline water to remove any harmful pesticide residues.

What’s the difference between water ionizers and alkaline water machines?

There’s no difference.

These terms are interchangeable.
