Home Health Living’s Best Alkaline Water Ionizer Machines

The IntelGadgets IT-580 alkaline water ionizer machine is an entry-level and affordable alkaline water ionizer. It’s ideal for those who are looking for the best and cheapest alkaline water ionizer. You may be uncomfortable with the average price of other alkaline water ionizer machines on the market. Machines such as the Tyent water ionizer are over $3000!

The water ionizer features 5 titanium electrolysis plates that are platinum-coated and are manufactured in Japan from KOBE steel. The ceramic ion membranes are manufactured in Japan and are non-toxic and temperature-resistant.

There are 7 different water level selections you can make, with 4 different levels of alkalinity, 1 level for purified water and 2 different levels of acidity. There is an extra-long and flexible tube for easily dispensing water.

Using electrolysis, the IT-580 separates tap water into acidic and alkaline water. The alkaline water ionizer also filters the water from common pollutants and odors such as chlorine and residual salt using an efficient activated carbon filter. It has a typical life of around 1585 gallons (6000 litres) or 6 months before needing to be changed.

The alkaline water can be used for drinking, cooking, cleaning and making tea and coffee. The acidic water is not suitable for drinking however can be used for facial cleansing, cleaning floors, for washing sensitive skin, relief from sunburn, as a natural after-shave and to help remove chemicals on fruits and vegetables.

What we really like about the IT-580 alkaline water ionizer is the safety feature that kicks in to prevent you from accidentally consuming acidic water. The safety feature shuts off the water flow automatically and converts to alkaline water to stop this from happening. There is also another safety feature that prevents the machine from overheating. This works by using a built-in thermostat.

The IntelGadgets alkaline water ionizer has a soft-touch button control panel with a range of different features and options available.  It has indicator lights that tell you when to change your filter and when to clean the machine, so that you don’t have to guess.

These same indicator lights let you know if your water is acidic or alkaline (red for acidic, green for alkaline), and there are clear color codes available to let you know the pH level of your water. There are buttons with text and icons to help you choose the water level you want according to what you want to use the water for, for example, “making coffee/tea”.

When it is time for a thorough clean, at the press of a button, the IT-580 will perform a full 2-minute cleaning cycle for you while playing music at the same time. Once the music finishes, you know that the cleaning cycle has also ended. You’ll know when the machine needs to be thoroughly cleaned by hearing an alarm that sounds once alkaline production has exceeded 8 gallons (around 30 litres).

The plates do not need to be replaced however the manufacturer recommends cleaning them every 1-2 years either by using a cleaning cartridge or running the acidic water backwards to clean the plates.

All components are BPA-free and lead-free and are made from food-grade materials.

When you buy the alkaline water ionizer, in addition to the machine you will receive 1 alkaline water ionizer activated carbon filter, all requires hoses and connectors, a user manual and a free water pH testing kit.

pH value: Between 4.5-11 (depending on the quality of the source water)

ORP value: Maximum of -850mV (depending on the quality of the source water)

There is a 2-year warranty.

The Aqua-Ionizer Deluxe by AirWaterLife is an alkaline water ionizer machine that features 7 platinum-coated long-life and energy efficient electroplates made using advanced technology. It also filters your water. It’s a great choice for those wanting an excellent quality alkaline water ionizer that has all the certification to prove its quality claims.

The water ionizer is certified 100% lead-free and pure titanium is used to form the plates before being platinum coated. It is made in the U.S.A.

The machine features ultra-responsive touch controls and has an LCD display screen. There are 7 water options available for you to choose: 4 ionized alkaline water levels, 1 non-ionized purified water level and 2 ionized acidic water levels.

You can make your choice by pressing one of the icons that represents the different ways that the water can be used. For example, “Cooking”, “Initial Drinking” or “Household Cleaning”. The ionizer machine then creates water that is suitable for the particular use chosen.

The alkaline water ionizer features a built-in activated carbon filter that filters out typical contaminants in your water, such as chlorine, benzene, trihalomethane, radon, pesticides and volatile organic compounds (VOCs). The filter can purify just over 1000 gallons (around 4000 litres). Many people ask whether it filters out fluoride and no, it does not filter fluoride. Activated carbon filters do not have the capacity to remove fluoride. The only way to remove fluoride is by using a reverse osmosis water filter system.

While this is a countertop water ionizer, you can use it under the sink providing you purchase the additional plumbing kit. The machine comes with the required attachment to use with most types of faucets, as well as the required tubes, fittings and installation hardware required for you to set it up yourself.

What we like about this particular alkaline water ionizer machine is that it has a 3 stage cleaning cycle. The first stage is a self-cleaning function that cleans the unit after each use. After 15 minutes of continuous use, the positive and negative poles of the plate reverse automatically for about 10 seconds. The second stage involves auto-cleaning where the machine uses an auto-plate washing function after every 10.5 gallons (around 40 litres). The final stage occurs after the machine has been in use for a year, with a manual clean required using the provided cleaning agent.

What sets the Aqua-Ionizer Deluxe from other top water ionizers is that each and every component of the machine is made from FDA-approved plastics. Other ionizer manufacturers do not have the same FDA approval.

The Aqua-Ionizer Deluxe is also ETL listed, RoHS Certified (lead-free), and is an ISO-9000 certified manufacturer.

Buying Guide

What is an alkaline water ionizer and how does it work?

A water ionizer is a machine that raises the pH level of water by separating the acidic and alkaline components of water. It does this by using electrolysis.

The water ionizer connects to your kitchen water supply and performs electrolysis on your tap water before you drink it. This occurs when a special connection diverts water from your faucet into the water ionizer unit.

Step 1:

There is an inflow of filtered source water (using the filters that are built into the water ionizer machine, or a separate filtration system that you have purchased). This source water contains both positively and negatively charged water molecules.

Step 2:

The metallic plates of the alkaline water ionizer are polarized, and positive cations are attracted on one side while anions (negatively charged ions) are attracted to the other side.

Step 3:

The water has been separated into two types of outflow. One outflow is concentrated acidic water while the other outflow is concentrated alkaline ionized water.

Your alkalized water has extra electrons, which gives the water a negative charge. The negative charge is measured in ORP. A water ionizer charges the water with a negative ORP. This means that your water has spare electrons that can neutralize the free radicals in your body.

The acidic water is waste water, however you can collect this water to use for cosmetic and cleaning purposes.

The alkaline water is ready for you to drink, to make tea or coffee with or to use while cooking.

Which is the best alkaline water ionizer machine for your source water?

As mentioned when reviewing each of the best water ionizer machines in this post, the pH and ORP levels depend on the quality of the source water.

As many of us would be aware, source water can differ from town to town, state to state and between tap water and well water. Therefore, the effectiveness of your alkaline water ionizer depends on the quality of your source water to begin with.

The best alkaline water ionizers featured in this review post are all suitable for city and well water sources, however the 7 plate and 9 plate alkaline water ionizers are more effective and result in better ORP values.

If you believe that the quality of your source water is questionable, or you have concerns about fluoride or possible lead in your water, then you may wish to add additional filters to filter out dissolved solids and chemicals out of your source water. You can purchase these at the time of purchasing an alkaline water ionizer machine- Amazon sells a range of filters, and you can read more about the best water filter for home use over here.

The built-in filters, and add-on filters available with most alkaline water ionizer machines do NOT remove fluoride from the water. You would need to look at purchasing a water filter that removes fluoride, which you can read more about here.

If you have pre-filtered your water and you are concerned about the minerals that may have been removed during the filtration process, you can add back minerals into your water by using a mineral filter, prior to ionizing the water. This is important for those who have a reverse osmosis filtration system, because reverse osmosis causes minerals such as calcium and magnesium to be removed during water filtration. Read more about reverse osmosis here.

In conclusion

Our best water ionizer reviews and buying guide should give you more information and the confidence in making the right decision when buying a water ionizer. Our alkaline water ionizer comparison information can also help you easily see which water ionizer would be the best for your needs.

If you aren’t ready to purchase a water ionizer just yet, then why not take a look at an alkaline water pitcher instead?

Remember, to improve the taste of your drinking water as well as the health benefits, you need to not only ionize your water but also filter the contaminants and odors out of the water.
