The Best Alkaline Water Filter

Whilst most people will probably have heard of alkalinity in relation to the pH scale, many might not know the difference pH can make.

The relationship between pH and their drinking water, and the hidden health benefits of drinking alkaline ionized water.

The pH Scale

As most of you might remember from high school science classes, pH (“potential of hydrogen” or “power of hydrogen”) refers to the level of acidity or alkalinity of substances, most notably water.

On a scale between 0 and 14, acidity is represented from 0-6, whilst alkalinity is represented by readings of 8-14.

Neutrality, the optimum water standard for us to consume and bathe with, is completely pure, and is represented by 7 on the pH scale.

Benefits Of Alkaline Ionized Water

Whilst limited scientific studies have been conducted on this subject, many people advocate drinking alkaline ionized water for helping a variety of ailments and long term, life altering conditions.

The suppression of cancerous growths has been cited as one major health benefit of drinking alkaline water, although this has not been supported by scientific study.

A reduction in blood viscosity can supposedly be achieved through alkaline water, allowing for higher intake of oxygen through the blood.

Advocates also claim an increase in hydration due to higher permeability and  “micro-clustering”.

Micro-clustering is simply the life cycle water goes through, essentially being evaporated, becoming water vapor in the sky, before falling down as rain, where it becomes more uniform and harmonically structured.

Proponents also claim that regularly consuming alkaline water can reduce neuro-degeneration, bone resorption, and help to halt DNA damage.

One affirmed benefit of alkaline water is the combating of acid reflux. This would be beneficial for people with extreme acidity, and is a much healthier method than regularly taking antacids.

Of course, our bodies are acidic for a very important reason, and maintaining these levels is paramount for continued efficacy in counteracting germs and properly digesting food.

Ultimately though, whilst advocates of the lifestyle push it as some untapped fountain of youth and vitality, it is worth saying that very little of the claims have been scientifically reinforced or studied.

With experts advising people to look where these claims come from: namely, the manufacturers of water filters.

Buyer’s Guide

Of course, before you should go ahead and purchase anything, it is important to think about what exactly you want from the product, how much you want to spend, and the volume of usage you expect to get from it.


The price is of course an important factor for most people.

Customers want a product that provides value for money, and whilst this doesn’t mean they are cheap, it does mean that they want a good ratio of effectiveness for money spent.

It is worth paying more if there is a guarantee of efficacy and quality, which is why it is important to read the reviews and do your research before committing to any product.


Whilst the physical specifications might seem shallow in comparison to other factors, any product designed for home display needs to both look attractive and fit in with existing decor/fitting styles.

It is also important to find products that are sturdy built and durable, especially for something as frequently used as a water filter.

This is especially true due to the presence of water, which can be a natural weakener over time, so starting from a position of strength and durability can mean a longer product lifespan and money saved.


Of course, what a product can offer to you as the customer is also important. With alkaline filters, you want a distinct boost in pH, as well as maximum filtration from contaminants and impurities in the water.

You also want long filter lifespans, and easy access to new filters when the time comes. Many products come with a timer which shows how long the filter has left, and this can be a handy thing to look out for when buying.

Frequently Asked Questions

Will The Taste Be Affected?

It is worth bearing in mind that with an increase in alkalinity, there will be some difference in taste. As with anything, this isn’t to everyone’s taste, and so this factor has to be considered before purchase.

What Are The Health Benefits? 

Whilst the health benefits are widely contested by scientists, and thus far haven’t been supported by scientific studies, there can be no harm in drinking cleaner, purer water.

What Is A Safe Alkalinity Level? 

For the best taste and safety, the US Environmental Protection Agency (EPA) recommends drinking water falls between 6.5 and 8.5 on the pH scale.

Water that is higher than 8.5 in alkalinity won’t necessarily be harmful, but it may have an unpleasant smell or taste.
