Alkaline Water vs Filtered Water: Comparison & Filtration Guide in 2023

Alkaline water vs filtered water is always a crucial debate. Drinking alkaline water in excess is not only a matter of your health, but it can lead to painful diseases in a person according to the views of some health experts.

Those who work in health fields say that alkaline water mixes with kidneys and other parts of the body and might damage them severely, resulting in many diseases.

Therefore, having filtered water is always recommended. But before reaching the conclusion directly, check out our detailed analysis of the difference between alkaline & filtered water, and the working and pros/cons of alkaline water.

Scroll down to learn more about our research and findings.

Difference between Filtered Water and Alkaline Water

What is Alkaline Water Filter - It’s Working, Advantages, & Disadvantages

The main difference between filtered water and alkaline water is that filtered water is free of alkaline substances and bicarbonates of alkaline metals and ions. It’s pure and ready to drink and is not harmful to human health.

On the other hand, alkaline water is full of bicarbonates and other ions of alkaline metals, including calcium and magnesium. It’s not good for health and needs treatment in different ways to make it clean and pure.

Although alkaline water is sometimes good when you drink it in excess, it may raise serious issues. An alkaline water filter is the best solution to this problem.

So, use alkaline water filtration systems for your whole house and enjoy your life beautifully with refreshing water.

What are the benefits and drawbacks of Alkaline Water?

What is an Alkaline Water Filtration System?

If you are living in areas near alkaline water like seas and rivers, then an alkaline water system is a basic need for you.

A water filter with alkaline ions resistance is a device that removes all chemicals, including alkaline metals. Now water is available for drinking purposes without worrying about the quality.

This Water filter is also known as an ionized water filter because its main aim is to eradicate the ionic compounds present in water.

These ionic compounds, when mixed with metals make water more dangerous.

Let’s now learn more about this water filter and how does it work? There are a lot of water filtering machines and each of them works differently. But here we shall be mentioning the ionic water filters.

How Does an Alkaline Water Filter Work?

The working principle of an alkaline water filter is easy to understand as there’s a filter that hinders the production of water with a high amount of ionic chemicals. Most of them are alkali metals.

But the question is how does this alkaline water filter do exactly? It’s simple but somehow complicated. The main work of an alkaline water filter is to make alkaline ion clusters that are smaller than the usual routine.

These water filters are free of ions easily digested by the body and easy to absorb. Moreover, an electrochemical and reverse osmosis process occurs in the overall filtration system.

Both of these works by an electrolysis method. Due to this the cathode and anode ends of the filter work differently.

If we look forward to the equation, it will be in the following ways.

  • 2 H2O + 2e– → H2 + 2 OH– (at the cathode)
  • 2 H2O → 4e− + O2 + 4 H+ (at the anode)

The above equations make a combination which is as:

  • 2 H2O(l) → 2 H2(g) + O2(g)
How Does an Alkaline Water Filter Work? Why is it so important?

In short, if we want to summarize the alkaline water filter working, then two main points work for the well-being of human health. These main points are:

  • This water filter minimizes risks of chlorine and other alkali ions to provide clean water in the tap
  • It adds some specific hydrates of alkaline ions, which are helping the users to use clean water

Why do I need Alkaline Water Filter?

A frequently asked question is “Why do I need an alkaline water filter?” It’s a unique and authentic question, and if you want to know the answer, keep reading this blog for more information that may have never checked before!

The need for alkaline water depends upon several factors. One of the considerable factors is to have a healthy lifestyle using alkaline water.

Advantages and Disadvantages of Using Alkaline Water Filter

With a number of pros, there are some cons to each product and the same is the case with an alkaline water filter. Here are some benefits and drawbacks of this system.

Pros of Using an Alkaline Water Filter 

Here are some advantages that assist many people in buying and installing a water filter to remove alkaline from the water.

Maintaining Acidity

The first and primary advantage of avoiding alkaline water and using a filter is to help the body maintain an acidity level, which is less than 7 pH.

And which is the negative amount of hydrogen ions in water.

Sometimes due to alkaline water body gets some diseases that are difficult to recover from. So, it’s the primary reason to avoid water full of alkaline metals and ions.

In this way, our immune system becomes more robust 8% up to normal routine.

Easy to Absorb Filtered Water

Most people claim that excessive use of alkaline water is tough to absorb by the body.

Moreover, if it gets involved in the immune system, it may cause several diseases, including nausea and sudden vomiting.

Furthermore, temperature and headache also occur. Some health workers also claim that it causes itching.

Given all these problems, water free of alkaline metals are easy to absorb in the body and makes you free of diseases.


Another advantage alkaline water filter is that it works as an antioxidant necessary for the body. Apart from daily routines if oxidants become low in the body, it’s hard to breathe even in excessive air.

The reason is that antioxidant has an indirect relation with the transportation of gases in the body. An antioxidant luckily helps to breathe easily in case of all gases.

Due to these antioxidant agents, our immune system becomes more vital than routine, another plus point. 

Cardio Boost Actions

While doing a survey, a team of professionals reported that cardio boost actions had been seen in people who use alkaline water.

In this disease, heart muscles become very slow in working and do not help transfer oxygen and carbon dioxide gases in the blood, which is the main aim of the heart.

An alkaline water filter is the best solution with all functionalities. It helps to lessen the effects of ions on the circulating system of the body.

Helps to Sooth Acid Reflux

If you are continually using alkaline water, it may cause many heart diseases, and tops of these include acid reflux problems.

In these situations, it’s widespread to get a condition involving heartburn or many others.

An alkaline water filter helps to soothe acid reflux which ultimately leads to the working of acids to work at maximum level and maximum protection against diseases.

Cons of using Alkaline Water System

A device has both advantages and disadvantages. In this section, we are going to mention some disadvantages of the alkaline water filtration system:

Disturbs pH

On the one hand, if it’s good for stomach pH, on the other hand, it’s not suitable for stomach pH.

It changes the pH level of the stomach and sometimes decreases it from the optimum level, which disturbs the normal digestion process.

On average, the stomach works at 1.5 to 2.5 pH levels, but it’s minimized to less than 1 which is an alarming situation.

pH level scale - Acid to Alkaline


Some people talk about the cost of the alkaline filter system. Yes, there is no doubt that it’s costly, and those who are poor can’t even afford this.

The installation cost is $475 and $2000 maximum, which is a point of happiness for some people and disappointment for many on the other hand

So, which is better – Alkaline Water or Filtered Water?

After reading the whole post on Alkaline Water vs Filtered Filter, now you can decide which water is best for you; either alkaline or filtered.

Both of these have their own value. Sometimes, it may be alkaline water which is good for health and sometimes filtered water.

Overall it’s filtered water which is good for health and other activities. We would recommend using filtered water because it has minimum risks of diseases and other health or washing issues.

The primary reason is that filtered water is not only good for health, but boosts the immune system of the body, good for washing purposes, and is good for animals on the other hand.

In short, an alkaline water filter is an important product for your home. But, if you have a large house then we would recommend you to go with the whole house water purification system that is able to remove multiple contaminants.

Moreover, one must use the correct and best 10-inch water filter cartridge for efficient filtration.
