Are you curious about whether your Brita filter can create alkaline water? It’s a common question, considering the increasing popularity of alkaline water.

In this blog, we’ll decode the science behind Brita filters and their impact on water’s pH level.

So, stick around to learn more about your filtration system and how it may or may not contribute to achieving that high alkaline balance in your drinking water!

Do Brita Filters Change the pH of Water?

Brita filters have the potential to change the pH of water by using hydrogen ions to neutralize calcium ions.

How Brita filters might affect water pH

Brita filters utilize activated carbon to remove impurities and contaminants from tap water. This filtration process includes the absorption of chlorine, lead, asbestos, copper, and other pollutants.

However, this process does not alter the pH levels of the water. The design focus for Brita filters is on reducing potential toxins in your drinking water rather than adjusting alkalinity or acidity levels.

In a conducted experiment where a pH test was administered on water filtered through a Brita filter, results showed around 5 on the scale which indicates acidic nature rather than alkaline.

While some brands offer features that can increase alkalinity in your filtered water, such enhancement is not available with standard Brita filters at present.

The use of hydrogen ions to neutralize calcium ions

Hydrogen ions are utilized by Brita filters to neutralize calcium ions in water. Calcium ions can contribute to water hardness, which is undesirable for many people.

The hydrogen ions from the filter react with the calcium ions, forming insoluble calcium carbonate that gets trapped and removed during the filtration process.

This helps to reduce water hardness and improve its taste and odor. Keep in mind that while Brita filters effectively remove calcium ions, they do not have the capability to make the water alkaline.

The Benefits and Controversies of Alkaline Water

Exploring the claims of alkaline water benefits

Alkaline water has been touted for its potential health benefits, but it’s important to look into these claims more closely.

Some believe that drinking alkaline water can help neutralize acidic conditions in the body and improve overall health.

However, there is limited scientific evidence to support these claims. Additionally, our bodies have natural mechanisms for maintaining pH balance, so consuming alkaline water may not have a significant impact on our overall health.

It’s always best to consult with a healthcare professional before making any changes to your diet or lifestyle based on claims about alkaline water benefits.

The potential risks and lack of scientific evidence

There are claims that alkaline water provides numerous benefits, such as detoxification and improved hydration.

However, it is important to note that there is a lack of scientific evidence supporting these claims.

Additionally, some potential risks associated with drinking alkaline water have been identified. These include gastrointestinal issues and interference with certain medications.

It is crucial for individuals to approach the consumption of alkaline water with caution and consult with a healthcare professional before making any significant changes to their drinking habits.

Making Your Own Alkaline Water

You can make your own alkaline water at home using alternative methods like baking soda or pH drops.

Using baking soda or pH drops

You can make your own alkaline water at home by using baking soda or pH drops. Here’s how:

  1. Baking soda: Add a pinch of baking soda to a glass of filtered water and stir it well. Baking soda, also known as sodium bicarbonate, has a high alkaline pH and can help raise the pH level of the water.
  2. pH drops: Purchase pH drops from a health food store or online. Follow the instructions on the bottle to add the drops to your filtered water. These drops are designed specifically to increase the alkalinity of water.


Brita filters are effective in reducing odors and improving the taste of water, but they do not have the capability to make water alkaline.

Brita filters are designed with the primary purpose of reducing odors in water. They use activated carbon to remove impurities and contaminants that can cause unpleasant smells, such as chlorine and sulfur compounds.

The carbon filter also eliminates organic matter, like sediment and bacteria, that may affect the taste of your drinking water. By improving the odor and taste of tap water, Brita filters make it more enjoyable to drink and encourage people to stay hydrated throughout the day.
