Does A Water Softener Remove Chlorine?

Does a water softener remove chlorine? When it comes to water treatment, many homeowners wonder if a water softener can effectively remove chlorine.

In this comprehensive blog article, we aim to answer this common question and provide valuable insights into the role of water softeners in removing various impurities. We will explain what a water softener does, what it removes, and whether chlorine is among those contaminants.

What does a Water Softener Removes?

Water softeners are primarily designed to combat water hardness caused by minerals like calcium, magnesium, and iron. These minerals can lead to scale buildup, reduced soap efficiency, and other issues.

According to Fresh Water Systems, we can confidently state that water softeners excel at removing these hardness-causing minerals. Some advanced models may also eliminate other impurities, such as manganese.

Chlorine in Water

Chlorine is a widely used disinfectant in the water treatment industry due to its effectiveness in killing bacteria and viruses. When added to water, chlorine forms hypochlorous acid and hypochlorite ions, which can break down the cell walls of microorganisms and prevent them from reproducing.

However, while chlorine can be effective at reducing the risk of waterborne illnesses, its presence in drinking water can have potential impacts on health and water quality.

Exposure to high levels of chlorine can cause eye and skin irritation, as well as respiratory problems. People with asthma or other respiratory conditions may be especially sensitive to the effects of chlorine.

In addition, chlorine can react with other substances in water to form disinfection byproducts (DBPs), which have been linked to an increased risk of cancer and other health problems.

One of the most common disinfection byproducts formed by the reaction of chlorine with organic matter is trihalomethanes (THMs). THMs are a group of compounds that include chloroform, bromodichloromethane, dibromochloromethane, and bromoform.

According to a study, long-term exposure to high levels of THMs has been linked to an increased risk of cancer, as well as reproductive and developmental problems.

In addition to THMs, chlorine can react with other organic and inorganic substances in the water to form a wide range of disinfection byproducts, including haloacetic acids, chlorite, and bromate. These byproducts can also have potential impacts on health and water quality. Thus, it is important to monitor the level of chlorine and disinfection byproducts in your drinking water.

Does a Water Softener Remove Chlorine?

Water softeners do not remove chlorine. They are primarily designed to address water hardness caused by minerals. Their main function is to remove calcium and magnesium ions through ion exchange or other methods, effectively softening the water.

Although some water softeners may have a limited effect on chlorine removal, it is important to understand that their impact in this regard is incidental rather than intentional. The amount of chlorine removed by a water softener depends on various factors, such as the specific type of softener and its design.

Why Chlorine is Removed from Water?

Removing chlorine from your water has several benefits. Firstly, it improves the taste and odor of the water, making it more pleasant to drink.

Secondly, chlorine is not good for individuals with sensitive skin or respiratory issues. Hence by using chlorine-free water, you may experience relief from irritation and discomfort.

Therefore, it is recommended considering your water treatment approach, it is essential to conduct water tests to determine the chlorine content. This will allow you to evaluate the effectiveness of your water softener in removing chlorine and identify the need for additional chlorine removal methods if required.

Alternatives to Water Softeners for Chlorine Removal

For comprehensive chlorine removal, it is advisable to consider supplementary treatments alongside your water softener. Several effective methods are available:

Activated Carbon Filters: These filters use activated carbon, which has a high surface area and adsorptive properties, to remove chlorine and other impurities from the water. They are commonly used in point-of-use systems or as part of a whole-house filtration system.

Reverse Osmosis Systems: Reverse osmosis is a highly efficient filtration process that removes a wide range of contaminants, including chlorine. These systems are often installed under the sink or as whole-house filtration units. And one such choice in this regard is Capella Reverse Osmosis Water Filtration which is specialized in removing chlorine, fluorine, and lead. The figure is show below:

Whole-House Dechlorination Systems: The whole-house filter is a specialized system designed specifically for chlorine removal. They use various techniques, such as carbon filtration, catalytic carbon, or chemical neutralization, to eliminate chlorine from the entire water supply entering your home. And one of the popular choices that is worth consideration is the AMI Essential Whole house filter as shown in the figure below:


In conclusion, while water softeners effectively tackle mineral-induced water hardness, they do not inherently remove chlorine. The presence of chlorine in water has health and quality implications, urging consideration for its removal. Utilizing supplementary methods like activated carbon filters, reverse osmosis systems or whole-house dechlorination systems is advised for comprehensive chlorine removal. Prioritize water testing to gauge the effectiveness of your chosen approach, especially if chlorine-free water is a priority.
