BEST UNDER SINK ALKALINE WATER IONIZER BUYER’S GUIDE
First up is the ionizing power of the device. This is the pH range it can apply to your source water. If you want to make alkaline water at home you need to take a look at the pH range of under counter ionizer.
Alkaline water for drinking has a pH in the range of 7.5 to 9. 9 is pretty high. We recommend staying below this. If you want to make strong alkaline water, (not for human consumption), you can look for pHs above this value.
The best under counter water ionizer machines come with low pH acidic capability. This means they can also create acidic water. For acidic water – look for a pH range below 7.
EASE OF OPERATION
How is the machine operated? Does it come with an easy-to-use control panel? It will be fitted below your sink so you will need a countertop controller.
Some under counter ionizers come with a countertop touch screen and control panel. Others attach a device to your faucet that allows you to choose water type as needed.
Make sure the operation system suits your needs and is easy to use. The last thing you want is to have to get in underneath your kitchen counter to access a control panel.
NUMBER OF PLATES
Check out the number of plates inside the ionizer. In general the greater the number of plates the greater ionizing capacity the machine has.
The best under counter water ionizers come with five or more plates. While the budget alkaline ionizers generally come with just 4 plates or fewer.
However, the number of plates isn’t everything. Be sure to take a look at the plate type, material, and ionizing performance.
TYPE OF PLATES
The ionizing plates are the part of the device that performs the ionizing reaction. Undercounter water ionizers use 3 different types of ionizing plates – mesh plates, solid plates, and mesh-solid combinations.
Mesh plates are the most efficient type. They are the best type for driving the electrochemical reaction that creates ionized water.
Solid plates are more durable. Although they are not as powerful as mesh – they are more robust and have a longer life expectancy.
The third type ‘mesh-solid’ combination plates are a hybrid between the two devices. They strike a balance between the two providing strong ionizing power with durability.
The best under counter alkaline water ionizers come with a built-in water filtration system. They perform two roles – water ionization and water filtration.
Take a look at the specification. It will tell you exactly what water filtration system your under-counter ionizer comes with.
The most popular filtration systems are activated carbon and ceramic filters. Water filters have a limited life cycle and will need to be replaced. Check out the cost of replacement when buying a new device.
INSTALLATION & SET-UP
Under-sink alkaline ionizers are easy to install. They connect directly to the water system below your counter and come with color-coded hoses for easy setup.
If you are not comfortable fitting them to your water line you should contact a professional plumber or tradesman. The installation will be a very straightforward job for them.
Once you have the device installed it is time to set it up. Each unit will vary slightly so follow the manufacturer’s steps for your particular device.
You’ll need to check the dimensions of the device to make sure it will fit beneath your sink or kitchen counter. It something that can be easily overlooked when reading through all the under counter water ionizer reviews.
Get a measuring tape out and start mapping out the dimensions you have available in your under sink space.
Then compare these against the device specifications. There’s no point ordering an ionizer that’s not going to fit in place when it arrives.
Prices for under sink ionizers vary greatly depending on model, specification, and functionality. The devices on the lower end of the scale come in at $1,500 while the high-end units retail for $3,000.
Purchasing a home water ionizer is an investment that will start paying dividends as soon as you start making alkaline water at home. Once installed, it will turn your regular tap water into ionized alkaline water.
Just think of the time and money you will save buying bottled alkaline water at the store.
ORP is a popular term used to describe the performance of a water filtration system. It stands for ‘Oxidation-Reduction Potential’.
It is a good parameter for indicating the quality of water. When it comes to ORP, the lower the value the better. Check out the ORP specification for the device.
Ionizing devices generate water with a negative ORP value. Twater with a low ORP is considered a good antioxidant and better for hydration.
CLEANING vs. SELF-CLEANING
Ionizers need to be periodically cleaned. Especially in areas that have a hard water supply due to limescale accumulation on the ionizing plates.
Take a look at the recommended cleaning regime. Is it something you feel comfortable with? You may prefer a device with self-cleaning capability.
Some of the high-end devices have a self-cleaning feature. That means cleaning will take care of itself. You won’t have to worry about getting stuck in and performing periodic cleans.
Check to see if the device comes with a warranty. Six-month and one-year warranties are common for under counter water ionizers. The very best devices can even come with a 5-year warranty.
A warranty shows that the manufacturer has confidence in their product. And it gives you peace of mind that you are buying something that has been built to last.
