Do I Need a Carbon Filter with My Water Softener?

Water softeners make your water safe to drink, but they can remove hardness from the water. The carbon filter may be necessary for removing calcium and magnesium ions that could harm you or the plumbing in your home.

This seems like an easy question, but there are many variables involved with this topic so it is important to research if you need a carbon filter before installing one on your system.

Carbon filters are a type of filter media that removes certain contaminants from water. They come in many different types, with the most popular being coconut shell carbon. The use of carbon filters is growing as people become more environmentally conscious and want to ensure their water is safe for consumption.

As the world’s population grows, there are more and more contaminants in our water supply. The two most common types of contaminants are bacteria and iron. A carbon filter is a device that attaches to your tap or faucet which has the ability to remove these harmful pollutants from your drinking water before it enters your home plumbing system.

Selecting filters can seem overwhelming at first, don’t worry though, this article will help you decide whether or not you need a carbon filter with your water softener and also help you decide the best water softener and carbon filter combo for your household.

Do I Need a Carbon Filter with my Water Softener?

Is carbon filter necessary for water softener? A carbon filter is an optional piece of equipment for a water softener. It is installed before the water softener and prevents any sediment from clogging up the unit. Carbon filters set in front of water softeners or no-salt water conditioners, on the other hand, create an excellent match. Carbon filters are self-cleaning and eliminate chlorine, tastes, smells, and sediment.

The carbon filter is placed before the water softener. This increases the life of the softener by eliminating chlorine before it enters the softener and provides superb clean water throughout the home.

The addition of a carbon filter can have real benefits because it removes other things that may be in your water, such as lead, cadmium, organic particles, and other things, but aside from those conditions or concerns, you probably won’t benefit from the filter because the water softener deals with the mineral issues in a different way.

The biggest downside of further filtration is simply expense and upkeep, so if you have any doubts about the quality of your drinking water, installing a filter shouldn’t hurt. It will most likely be most effective if positioned in front of your softener system.

A carbon filter with a water softener can ensure that calcium and magnesium ions are removed from your water supply. Make sure you have one installed if it is important for your health or the health of household members who drink filtered tap water.

Lastly, carbon filters are designed to remove contaminants from your water by separating them into an acidic compound and neutralizing it before returning them back into your home’s plumbing system. They also have the added benefit of protecting against lead poisoning, which can cause anemia in children and liver damage if left untreated for too long.

Why you need a water softener and carbon filter combo

Many people are under the misconception that their water is perfectly safe and clean simply because they are using a water softener to filter their water. However, many other pollutants (such as iron, manganese, copper) can be removed by carbon filters used in conjunction with a water softener system.

A water softener does not give you cleaner water, but rather it changes the hardness of your tap to make it softer. The most common contaminant that a carbon filter is able to remove is chlorine and chloramines in drinking water.

If you have a water softener and you want to ensure that your family is getting the cleanest, safest drinking water possible then it’s important that you add carbon filters with both systems. The carbon filter removes heavy metals like lead and arsenic from the treated tap water which can be highly problematic if not removed before consumption.

How does a carbon filter work?

The process of removing contaminants by adsorption is known as carbon filtration. The benefits of using a carbon filter are that they remove chlorine, lead, mercury, and other heavy metals from water. This helps to reduce the total cost of hard water treatment.

A carbon filter is a type of water treatment device that attracts particles, specifically iron and manganese. The adsorption process adheres the particles to a surface like Velcro by means of an electrostatic charge or chemical reaction in order to remove them from your tap water.

The carbon filters are one way for you to make sure your tap water is safe enough for drinking because they can be installed upstream where they will effectively trap all particulates before reaching the faucet.

A carbon filter is inserted into the water softener, which bonds to organic compounds that are polar substances. This reduces the odor and taste of hard water in your home’s drinking tap. The more often you clean the filter, the more effective it becomes at filtering out these contaminants from your water supply.

A carbon filter is an important part of your water softener. It helps to reduce some chemicals and debris that could potentially be harmful to you or your family, like chlorine byproducts which can cause cancer, among other health issues.

Is there a difference between a carbon filter and an activated carbon filter?

What is the difference between a carbon filter and an activated carbon filter? Carbon filters absorb harmful chemicals such as chlorine, lead, asbestos, or benzene. Activated carbon on the other hand can be used to remove impurities from water by heating it up and then releasing its chemicals back into the air.

Carbon filters are often used in water filtration systems to remove contaminants or block out other unwanted substances. Activated carbon is a type of filter that has been activated by the process of heating it up and adding hydrogen, oxygen, or nitrogen gas. This activates all pores on its surface area so it can hold more contaminants than regular carbon filters.

There is a difference between a carbon filter and an activated carbon filter in the water filtration process. A Carbon Block Filter has fewer restrictions, but it also creates channels where particles can go through easier.

It’s not advisable to use this type of filtering system because if little sediment goes into the channel area, then there will be more than enough space for bacteria and viruses to grow inside them.

A typical example would be when you’re using your refrigerator or dishwasher without cleaning out the filters. You can prevent this by using a carbon filter in your water softener.


In conclusion, Combining your Water Softener with a carbon or KDF filter is not required, but it will help remove up to 97 percent of chlorine as well as VOCs, pesticides, herbicides, and heavy metals. Aquasana is my overall top selection for the finest whole-house water softener and carbon filter combo.

If you’re only interested in improving the flavor and quality of your drinking water, you might be better off investing in a domestic reverse osmosis system, which can remove up to 99.9 percent of TDS. A carbon filter (such as activated carbon or coconut shell carbon), a RO membrane, a pre-filter, and a post-filter are all part of this system. However, reverse osmosis filters are not recommended for hard water since the minerals might harm the semi-permeable membrane.
