What is an Alkaline Water Ionizer?
Before getting to the reviews, I am providing this primer for those who are not familiar with alkaline water ionizers. You can skip straight to the alkaline water ionizer comparison and reviews if you would like.
An alkaline water ionizer is a machine that alters the pH of water. The terms “alkaline water machine” and “alkaline water ionizer” mean the same thing and are used interchangeably. Without getting overly technical, alkaline water ionizers alter the pH of water by using electricity to split its alkaline and acidic components.
In simplest terms, alkaline water is less acidic water. A water ionizer will remove the acidic properties of your tap water. Most city tap water has a pH of around 7. A water ionizer can boost the pH of your water up to about 11, effectively reducing the water’s acidic properties. Below is a chart that shows the standard pH scale.
The terms “alkaline” or “acidic” in reference to water ionizers are referring to the pH level in the water. Acidic water produced by water ionizers has a pH level of about 3 which is comparable to soda and vinegar. It is not recommended to drink water with higher acidic properties, but it is useful for cosmetic and cleaning purposes. On the other end of the spectrum, alkaline water with a higher pH produced by water ionizers are comparable to the juices of kale and spinach.
Most city tap water is considered neutral with a pH of approximately 7. Highly alkaline water has a pH of around 10 or 11. Below is a table that summarizes common foods and liquids with their respective pH levels. The higher the pH level the more alkaline the item is. The lower the pH level, the more acidic the item is.
|Soda, Pickles, Vinegar|
|Beer, Wine, Coffee, Chocolate|
|Soy Milk, Cocoa, Honey|
|Coconut, Grapes, Plums|
|City Tap Water|
|Olives, Bell Peppers, Cabbage|
|Green Tea, Lettuce, Green Beans|
|Highly Alkaline Water, Raw Kale, Raw Spinach|

What to Look for in an Alkaline Water Ionizer
The items below are a high level overview of what you should look for when comparing water ionizers. Reading through this section will quickly bring you up to speed on the key features of water ionizers.
The pH range is the minimum to maximum pH a water ionizer can produce. Many factors determine the actual pH of the water that runs through the machine including the pH of your water before ionizing, hardness or softness of your water, minerals in your water, etc. The quality of water you put into the ionizer plays a big role in the pH of the water that comes out. Most alkaline water ionizers come with a testing kit. You can also test the pH of your alkaline water with pH test strips that can be purchased separately.
ORP is an acronym for oxygen reduction potential range. It is also referred to as “redox”. The term redox comes from the combined terms “reduction” and “oxidation”. Reduction is a decrease in the oxidation state of water and oxidation is an increase in the oxidation state of water. The ORP is measured in millivolts (mV) and can be determined with an ORP meter. It is widely agreed that water’s ORP is more important than the pH level. The lower the mV value the better antioxidant. You want to see a negative reading. A lower ORP can be achieved by the number of plates a water ionizer has and its wattage. This is why the number of plates and wattage is so important when choosing a water ionizer.
Plates are one of the most important components of a water ionizer. Plates are used to ionize the water. The plates are electrically charged and water is ionized as it runs over them. When buying a water ionizer, you want to look for the number of plates, the total surface area of all plates combined, and the style of plates used.
Total surface area of the plates is more important than the number of plates. In general, plates with larger surface area allows for more potent water. They have the capacity to produce water at a much lower ORP (water with more antioxidant properties).
There are three different types of plates – flat, mesh, and slotted. Almost every water ionizer manufacturer coats their plates with platinum or titanium. These metals are used because of their electric conductivity.
The more power available to the ionizer, the stronger the water the ionizer can produce. The more wattage per square inch on the plates results in increased ionization. This allows for lower ORP values, or water with greater antioxidant properties. A higher wattage is especially useful for those requiring alkaline water at a higher flow rate. If you need to fill up multiple jugs of water quickly, look for an ionizer with a higher wattage.
The presets allow you to quickly choose the level of alkalinity you want your water. Think of these presets as the radio stations you have set on your car radio. For example, there may be a preset for daily drinking with a pH of 8, a coffee and tea preset with a pH of 9, and a cooking preset with a pH of 10 or 11. You select the preset and the machine will produce water with the alkalinity you selected. Presets make it easy to quickly select the pH levels, or level of alkalinity of your water.
Ideally, water ionizers should be cleaned each day they are used. Most water ionizers will either clean automatically or clean by the push of a button. In fact, some machines will clean after each run. Either way, you will want to look for one that is self-cleaning. Regular cleaning prevents build-up on the plates and will increase the life of your ionizer.
Filters need to be replaced after a certain period of time. Please see the water ionizer comparison chart below for the filter life of each ionizer. Filters are an added expense, but you can save money in the long run by owning your own water ionizer and not buying alkaline water from a store.
Placement of the Water Ionizer
There are countertop models and under sink models. Some countertop models have a kit you can purchase separately which allows you to install your water ionizer under the sink. With an under sink water ionizer, the machine and tubes are out of the way. The line that carries the alkaline water is usually installed where your sink’s built in soap dispenser is located. If your sink does not have a built in soap dispenser, you may have to drill a hole. This is why many people opt for a countertop model. It’s up to you to determine what placement best meets your needs.
Air Water Life Aqua Ionizer Deluxe Review
The Air Water Life Aqua Ionizer Deluxe is the best alkaline water ionizer for most households. I selected this model based on performance of the machine, upfront cost, and overall cost of ownership. This water ionizer is considerably cheaper than many of the higher end water ionizers and delivers similar results. It features a total of 7 presets which allow you to quickly choose the level of water alkalinity you need. The 7 presets include:
- 4 alkaline water presets – initial drinking, daily drinking, coffee and tea, and cooking.
- 1 preset for purified water with normal alkalinity (pH of approximately 7). You can use this setting if you just want filtered water that is not ionized.
- 2 acidic presets – cosmetic and cooking. These “acidic” presets have about the same acidity as soda or wine. It is not recommended you drink the water with pH levels this low, but it is useful for other purposes. The minimum pH level this ionizer will produce is 4.5. However, the discharge water (line going into the sink) may be as low as 3. The discharge water is great for cleaning.
This alkaline water ionizer is BPA free and is made with FDA approved plastics. It is also ETL certified. ETL is a step above the more common UL certification.
It acts as both a water purification system as well as a water ionizer. It features adjustable pH levels between 4.5 – 11 which can be selected through an easy to understand interface on the front of the machine. The 7 different pH presets make it easy to operate and it is self-cleaning.
Below is a photo of the front of the ionizer showing the different settings and options. Once you select a setting, such as drinking water for example, it will remember your selection each time you use the machine.
It is simple to set up. It connects directly to your faucet with the installation kit included. There are three different adapters included which allows this water ionizer to connect to 99% of faucets. If you are having trouble fitting to your faucet, the company has great customer support who can guide you through the process or suggest alternatives if your situation is unique. Expect to spend about 30 minutes setting the machine up. I have included a step by step installation video at the end of this review.
This is a countertop model which conveniently sits beside your kitchen, bathroom, or utility room sink. There is also an under sink kit available from the manufacturer if you need it. There are two lines coming out of the ionizer – one that supplies your drinking water and another that is used to dispose of the discharge water down the sink. Be aware when you first setup your ionizer, the lines do not lay flat, but they will after you start using the ionizer.
The carbon filter used by this water ionizer has a life of 6,000 liters before it needs to be replaced. With normal usage, the filter should last about a year. New carbon filters are relatively cheap compared to other models, costing about $40.
Finally, it comes with a pH testing kit which you can use to test your water to make sure it is meeting your expectations. To test the pH levels, let the water run through the spout for a few seconds to rid any residue from the tubes. Fill the supplied test tube about ¾ full with water from the ionizer. With the pH reagent supplied, put two drops in the test tube water and shake. The reagent will cause the water to change colors. Compare the color of the water to the pH chart that is also supplied. This will tell you the pH of the water. There are also pH test strips you can buy which will give you the same end result.

Tyent MMP 11 Plate Water Ionizer Review
The Tyent MMP 11 plate water ionizer is best suited for business settings such as a health club, gym, or other high traffic locations where a fast flow ionizer is appropriate. Its high flow rate allows containers to be filled up quickly and can withstand heavier overall use. It supports very high and low pH levels as well as very low ORP mV values (approximately -850 mV), even when the water is running at a high flow rate. However, for everyday household use, you can save money by using our recommended ionizer. Just slow down the water flow rate and you will achieve similar results.
As its name suggests, this Tyent water ionizer features 11 plates. It also has a very impressive power supply at 750 watts which facilitates highly antioxidant water (low ORP mV values). These two features are key in allowing this water ionizer to produce such impressive results at a high water flow rate.
There are six basic settings available on the LCD screen. The settings include three alkaline levels, 2 acidic levels, and one H2O setting. The H2O setting produces only filtered water with no ionization, just filtered drinking water.
You may be wondering how there are 55 presets with only six basic options on the LCD screen. This is because for each of the presets (except the H2O), you can adjust the ionizer to the desired alkaline level. Each city’s water system has a different mix of mineral content. For example, if you live in Boston, the water may have more minerals than Los Angeles. If you live in New York, the water may have a different pH than Houston. Using the reagent drops included with the ionizer, test a glass of tap water as your base case. From there, you can adjust, or customize, the ionizer for each of the presets to meet your needs based on your city’s water properties. This level of customization can only be found in a machine of this quality and is absent from most of the cheaper water ionizers.
Below is the LCD screen on the front of the Tyent MMP 11 water ionizer.
Tyent MMP 11 Water Ionizer Installation
Installing a Tyent water ionizer is a simple process. The installation process takes about 20 minutes. A pair of scissors, pliers, and a small towel are required. Below are the parts included out of the box and instructions to install once you receive your water ionizer.
The first step is to remove the aerator from your faucet. The aerator is located at the tip of the faucet where the water comes out. To remove, you will need to screw it out with a pair of pliers. To protect your faucet, wrap a small towel around the aerator. Then, with a pair of pliers, grip the aerator and loosen. Once it is loose, you can continue unscrewing by hand.
The next step is to install the diverter fitting ring. This goes in place of the aerator. There are many types of faucets on the market. Tyent has included several different types of diverter fitting rings that will fit most faucets. If necessary, use one of the black rubber washers to ensure a tight fit.
After the fitting ring is installed, attach the water diverter. The water diverter will allow you to switch between regular tap water and alkaline water as necessary. There is a knob on the side you can turn that has two positions. In one position, the water will flow out of the faucet as normal. The other position will divert water to the water ionizer. For a tight fit, you can wrap a small towel around it and tighten with a pair of pliers. Be careful not to over tighten.
After the diverter is installed, you will need to cut the white hose into two pieces. One piece will carry the water from the diverter to the water ionizer. The other piece will carry the acidic water, or wastewater, into the sink to go down the drain. To measure for a proper cut, place the water ionizer beside the sink where it will permanently sit. Measure the distance between the diverter and machine. Leaving enough slack to rotate your faucet, cut the hose. You will insert this hose into the “inflow” hole on the back of machine. The second piece of hose will be plugged into the “outflow” hole on the back of the machine.
Next, attach the hose from the “inflow” hole to the diverter on the faucet. Remove the nut on the side of the diverter. Thread the hose through the nut and slip the hose over the barbed piece on the diverter. Clamp the hose down on the diverter by screwing the nut back in place (over the hose). This will hold the hose in place.
The hose coming out of the “outflow” hole on the water ionizer should be threaded through one of the suction cups provided. Attach the suction cup to the side of the sink. The purpose of this hose is to carry the acidic waste water down the sink drain.
Screw the water outlet tube to the side of the machine. This is the piece that carries the good alkaline water that is meant for consumption. It is flexible and can be put in the position required.
The final step is to plug in the water ionizer and turn the power on. The power switch is located on the back of the machine near the “Inflow” and “Outflow” holes. To test, turn the tap water on by running cold water through your faucet. Use the water diverter knob to direct water to the water ionizer. Water should now run out of the water ionizer.
That’s it! Your Tyent water ionizer is now installed!

Uses of Alkaline Water
In addition to normal day to day drinking, alkaline water ionizers can serve water for other purposes including cooking, cosmetic applications, and cleaning.
Strong alkaline water (pH of 8.5 – 9.5) does a better job than tap water cleaning pesticides and other toxins off of fruits and vegetables, including those labeled as organic. The reason alkaline water does a better job at cleaning produce is because pesticides are oil based. Regular tap water is not as effective at removing these chemicals.
Acidic water may improve the appearance of your skin. Many people use it to treat acne and other slight skin problems. You can use higher pH alkaline water to wash your hair, shave, and even mix in a few gallons with your bath water.
It is important to note that acidic water should never be consumed.
Acidic water with a pH level of 3 – 4 is great for cleaning. Acidic water with a pH this low will kill germs on contact. The strongest acidic water your ionizer will produce is the discharge water that drains in your sink.
According to the LA Times, the Sheraton Delfina hotel in Santa Monica, CA switched from chemical based cleaners to electrolyzed water. According to the article, the water is strong enough to kill anthrax spores and at the same time is harmless to their employees.
Alkaline Water Ionizer with Your Reverse Osmosis System
If you have a reverse osmosis system, or “RO system”, an additional filter is required. A reverse osmosis system removes almost everything (including minerals) from the source water. A water ionizer requires minerals in your water to make it alkaline by bringing the pH up. Since reverse osmosis water is “dead water”, you will need to install a filter between the reverse osmosis system and the water ionizer to restore the “good minerals” back into the source water. With the newly restored minerals, the water ionizer will work just as well as it would without the reverse osmosis system.
Storing Alkaline Water
Drinking alkaline water directly from your water ionizer is always best. If you must store it, alkaline water will retain its ionized properties for about 24 hours when in a sealed container and 48 hours if refrigerated. Store your alkaline water in a glass container when possible. A BPA free plastic or ceramic container is the next best thing. Never store alkaline water in a metal container! This includes stainless steel. Metal is a conductor of electricity and the water will quickly lose its antioxidant properties if stored in a metal container.
I hope you have found this buyer’s guide helpful and informative. If you are looking for the best water ionizer for home, go with the Air Water Life Aqua Ionizer Deluxe. If you own a business, your best bet is the Tyent MMP 11 water ionizer.
