Ion Exchange Water Filters and How They Work

Ion exchange is a unique way to clean water and improve its quality and taste. While there are several water filtration options, this type is different than any other options. It mainly works to soften water and eliminate certain harmful contaminants that are often in the water we drink.

Hard Water

Water that contains dissolved compounds of minerals including calcium and magnesium is known as hard water. It can also contain some metallic elements. It can cause your water to have an unpleasant taste, but it can also cause some other unwanted effects. It can cause your laundry to become stiff and dingy, create mineral deposits on your dishes, cause you to use a lot of soap, cause built up soap curd to stick to the bathtub or shower, and scale buildup in the sink, tub, faucets, and appliances.

How it Reduces Hardness

The charge in water must be neutral. Ion exchange works to neutralize the water. If the positively charged ions, such as calcium ions, are removed, either an equal amount of negative ions need to be removed, or the positive ions need to be replaced with new positive ions. Ion exchange works to not only remove the harmful contaminants. but replace the ions with others that have the same charge. When the ion exchange filters remove calcium from the water, it replaces it with another, harmless mineral such as sodium.

How Ion Exchange Works

In an ion exchange filter, there is a long column filled with small polymer resign beads. As the water flows over these beads, the ion exchange happens. They work to replace the harmful ions with harmless ones. The water goes through hard, and exits softened.

Final Filter Step

After the water goes through the ion exchange process, there is a final filter step to ensure that the water is at the highest quality possible. During the final stage, the water passes through an activated carbon filter. This absorbs other water contaminants such as chlorine and other organic compounds. This step does not affect the mineral content of the water but works to improve the taste and quality.

How to Know if an Ion Exchange Filter is Right For You

An ion exchange filter is the best option if you deal with hard water in your home. The best way to know if you do is to have your water tested. With a water test, you will be able to see exactly what is in your water. If the test shows that you deal with a lot of hardness in your water, you can consider using an ion exchange filter. If there are other contaminants infecting your water, you will be able to decide what filtration option is best for your home’s specific needs.
