What to Consider for the Best Water Ionizer?

To be sure, not every alkaline water machine was created equal. There are lots of features that you need to look for.

Undercounter, Countertop, or Convertible

The best water ionizer can come in many shapes. The models in our list of reviews come in many styles, such as convertible, countertop, and under-counter. This unit can be attached to your water supply under the counter so you can get the ionized water easily. However, you have to be sure about the dimensions so you can get the best fit.

Types of Plates

When it comes to the best water ionizer, you have to look for its plates. There are many different types, including slotted, grid, mesh, solid, and more, and this feature determines the electrolysis process that delivers your alkaline water. So when you are making your choice, you must check the plates. It might take some research to get used to, but a simple rule of thumb is that the more plates you have, the more efficient machine will be.

pH Levels

The pH level describes how acid or alkaline water is. When it comes to the pH scale, a reading over 7 is alkaline, 7 is neutral, and below 7 is acidic.

ORP range

ORP stands for oxidation-reduction potential, which is also important to consider. The ORP range indicates the amount of electron charge in the water, which is measured in millivolts. When it comes to choosing the best water ionizer, you want this to be a a negative number.

Many experts said that if the level is at the lower end of the ORP range, the potential is greater for anti-oxidation. However, you should keep in mind that this claim has not been proven yet.

Filters

As far as the filters are concerned, you have to be careful. Filters are designed to eliminate all the impurities from the water, but not all water filters are equal. Some are better than others at eliminating impurities, and others have different drawbacks, like a low flow rate. A carbon filter is often a great option. You also have to be sure about the expected lifespan of water filters and how much it costs to replace them.

Most filters are designed in such a way that they will need to be changed at least annually. Make sure to check the product specifications..

Ease of Installation

Lots of units are designed to be easy to use. They are also easy to install, but the under-counter option takes more time for installation. So consider your needs – maybe all you need is a countertop model so that you can get started straight away.

Warranty

Lastly, you want to be certain that your purchase will be a reliable product. For security, check that the machine you’re thinking of buying comes with a warranty. Make sure to check the terms and how long the warranty lasts – a number of the models in our list of reviews come with a lifetime warranty, but others don’t.
