pH Levels in Filtered Water Compared to Unfiltered Water

It is generally agreed by doctors and scientists that having a good pH balance is a significant factor in your overall health. Your pH, or potential hydrogen level, is influenced by what you are eating or drinking. pH is the measurement of the concentration of hydrogen ions and is based on a scale that goes from 0 to 14. It’s important to recognize that pH levels under seven (<7), the neutral level, are considered to be acidic and levels above seven (>7) are considered to be alkaline.

In terms of drinking water, pH value provides a solid indication of the hardness of the water that is coming out of your taps. You may have read about hard water in a previous blog post of ours and understand that it means your water contains a significant amount of dissolved minerals such as calcium or magnesium. Hard water also tends to have high levels of pH whereas soft water tends to have a low pH.

Let’s shed some light on the pH levels in filtered water compared to unfiltered water and how this translates to your health.

What pH Should my Drinking Water Be?

According to the below graph published by Environment Canada, one could conclude that the ideal pH of your drinking water should be between six and eight. This graph also gives you a good idea of how the most acidic things – like battery acid – stacks up against the most alkaline-rich things – like lye.

pH Levels in Filtered Water

In an article by Health Canada discussing pH, they reference a 100-city study where 17 cities had a pH level greater than nine (>9) as well as some cities with pH levels as low as five (5). This sheds light on the fact that even treated municipal water can still fall above or below the neutral levels of pH.

What pH Levels of Filtered Water Mean to You

Water filtration systems such as Filter Butler’s Whole House Water Filter as well as a water softener can help to regulate the potential fluctuations of pH levels in unfiltered and even city water. For example, a water filter can prevent or reduce metals such as copper, iron, lead and zinc from passing through your pipes. These metals are also very acidic and can in high levels cause unwanted health issues ranging from headaches, stomach and chest pain, and increased susceptibility to the common cold. In addition to filtering out acidic substances that may affect your health, water filters prevent metallic-tasting water as well as damage to the piping that feeds your water and the appliances that use it.

On the other hand, hard or alkaline water does not pose a health risk and is often referenced as being part of a healthy diet. While the jury seems to be out on the pros and cons of introducing more alkaline into your diet, water that is rich in alkaline can create problems – such as scale deposits – within your home. A water softener can help to minimize the scale on silverware, glassware and faucets, preserve the lifespan of all water-using appliances, and improve the efficiency of these appliances by as much as 20 to 30 percent.

pH Levels in Filtered Water

In short, water filters remove acidic substances such as heavy metals and water softeners remove alkaline deposits from scale.

The benefit of a Whole House Water Filter and a water softener is that they prevent your water from becoming too acidic or too alkaline, providing you and your family the cleanest, purest and safest water while allowing healthy levels of minerals through your pipes for improved taste.

    what a shit article! Title leads you to believe they will disclose if filtration raises or lowers ph levels and article says nothing about it.

    The indicator for acidity, alkalinity, or basic is known as the pH value. A pH value of 7 means a substance is neutral. The lower value indicates acidity, and a higher value is a sign of alkalinity. The article makes sense but the author should have explained that at the beginning;)

    is it possible to increase acid level after filtration of drinking water with any water purifier ?
