Buying Guide – Best Water Ionizers

With a really good number of options being available for you, at one point in time, you may find it difficult to make a single choice. This is why we have made this list of considerations for you when buying the best water ionizer to narrow down your search. Now as mentioned before, there are way too many options to choose from and each and every one of them has different features and styles. But there will be that one best water ionizer that will just scream perfect for you, make sure you have no second thoughts and purchase that product right away.

Undercounter vs Countertop

Now while talking about the counter and countertop feature, this feature depends totally on whether there is enough space in your kitchen to store it below a counter or above. These products are particularly designed to be small and compact which clearly says it does not occupy much space to be stored. So, if you have really limited counter space then it is best for you to consider the other option that is under the counter rather than a countertop.

Filter efficiency

Some best water ionizers come along with additional benefits like eliminating pollutants like lead and chloride from your water because they have built-in filters. Due to those built-in filters, the water finally served to you from the ionizer is safe and much more enjoyable to consume especially taste-wise.

The efficiency of every water ionizer is going to vary from company to company and model to model since not all of them are built with the same features and styles in mind. Regardless of water pressure, some water ionizers can purify your water easily as well as quickly. But only some water ionizers can do that, not all, since their efficiency varies. 

The most important thing for you to tick off your list before you purchase an ionizer is its lifespan. Some ionizers can last up to a period of 12 months before they need to be changed while on the other hand some of them last only up to 6 months or even less. Remember, all filters need to be taken care of and changed after a certain period of time due to the buildup of various sediments. 

So you must make sure to check the costs for replacement filters as well before you make a purchase and then proceed accordingly.

pH Range

No doubt, the main reason why people consider investing their money in water ionizers is because of their capability to produce ionizer water i.e. alkaline water. This obviously depends on the ionizer’s ability to make a change in the water’s pH level. In short, the alkalinity level of the water in your homes is indicated by the pH level of the water. If the pH level is 1 then it suggests that your water is highly acidic in nature, whereas water with a pH level of 14 would be alkaline. And finally, a pH range of 7 suggests that your water is neutral. 

You might be wondering why all these matters so much…let us tell you why. The pH level of your water determines for what purpose it can be used. For instance, water that has a really low pH level is best suited for cleaning. 

While mildly alkaline water is good enough for us to consume on a regular basis. You should know alkaline water is suitable for cooking as well. This is why it matters. Pay good attention to these details.

ORP Range

ORP stands for oxidation-reduction potential. This refers to the capability of a water oxidizer when it comes to lessening the amounts of oxidation levels. Everything should be oxidized inside the product. How do you decide whether the product you choose has the right ORP range? It’s pretty simple. The lower the ORP range, the safer your water is to consume.

Built-in water filter

Talking about the built-in water filters you need to make sure you take into account a lot of things at the time of purchase without fail. Things like basic details such as the lifespan and price. By now you already are aware of the fact that after a certain point in time you will have to replace your filter. Due to the buildup of sediments and other reasons it is wise to change your filter. You can determine when you have to replace it by the quality of water it serves you at that very moment. Therefore, it is necessary to consider the maintenance costs at the very beginning of your purchase. Usually, the filters last from 6-12 months, but you never know since all these factors differ from manufacturer to manufacturer. 

But in case you tend to have a good water supply, it is best for you to select a model that has a very powerful filter so it can very quickly cope up with the water pressure.

Installation process

If you are someone not really great with the installation process and will need another person to do it for you, then you shouldn’t worry because water ionizers barely need any installation to be done. Especially countertop filters don’t need much of an installation to be carried forward. 

But it’s not the same with under-counter products. The installation takes a tad bit more time and gets a little difficult too especially for somebody who isn’t great with the installation process. But that doesn’t mean it’s impossible, it’s just a little bit more than the countertop ionizers. You can always search for videos online and make them work.

Manufacturer support

Most of these ionizers are built to be installed without any professional support since most of them are really easy to install. You won’t have to sweat off at all while completing the process, that simple. But when you have a manufacturer’s support 24/7 then it’s always much better. For instance, in the process of installing your best water ionizer, you tend to have a doubt or problem with some part you can always use the live manufacturer’s guidance to get answers to your questions.

Number of plates

To make you aware of why the plates are so important to consider while purchasing your item, let us tell you about the plates themselves. These plates are where the water is changed from acidic to alkaline. 

It is really important to know the material used in making the plates because they come in direct contact with the water.

Warranty

You should always make sure the water ionizer you choose to purchase has a minimum warranty of 6 months to anywhere up till a year.

Conclusion

We hope this article of ours was of utmost use to you in purchasing a water ionizer. If you are sure that water ionizers are for you, then it’s the right time for you to start searching for the product of your choice. 

It is best for you to pick out the best amongst the good since there are many options available for you to choose from.
