Usually, this is the first question raised when it comes to removing chlorine from tap water. Before purchasing any water treatment system, it is recommended to get your water tested. 

This way you can find out if there are other contaminants you should treat as well, so you can choose the best suitable filtration system for your specific water issues.

Is chlorine dangerous to your health?

As I have mentioned before, chlorine is an inexpensive disinfectant that is used to protect the consumer from dangerous water-borne diseases. Sometimes it is used together with chloramine, which is formed by adding ammonia to water.

However, chlorine is used to protect you from harmful chemicals entering your drinking water, it has some significant side-effects you should take into consideration.

Chlorine and its by-products in water can lead to some serious issues, especially if you have a special health condition and you are part of at-risk categories.

Let’s see the heath impact of chlorine in your water:

  • Chlorine in your bathing or shower water can be the answer to dry hair and skin, unpleasant skin rashes, itchiness, psoriasis or eczema flare-ups. 
  • It can lead to asthma attacks if inhaled during showering or bathing.
  • Chlorine by-products are cancerogenic and their presence in your water can lead to an increased risk of breast cancer or bladder cancer.
  • It can have an impact on the nervous system of infants and small children.
  • It can be the reason of reproductive problems and miscarriage.

How to remove it from your water?

Whether you are an at-risk category or you worry about the harmful effects listed above of long-time chlorine exposure, there are various methods you can try to remove chlorine from your tap water.

Some of the following methods are highly efficient against chlorine, but they leave the chloramine behind. Other methods fight effectively both chlorine and chloramine. 

The good news is that you have numerous options to choose from:


Aeration is a simple practice of leaving water out in the air for chlorine to fizz out. In order to accelerate the dechlorination process, you can introduce bubbles into water by using an air pump or air stone.

A disadvantage of aeration is that it takes a lot of time to complete the process. Also, aeration helps chlorine evaporate, but chloramine will remain in water.


Boiling your water for 15 to 20 minutes is a great option to get rid of chlorine. But as in the case of aeration, boiling will leave the chloramine in your water for much longer.

This method is also a great way to remove bacteria and viruses from your drinking water, but it is not a perfectly reliable water treatment. Boiling water actually increases the concentration of such harmful contaminants as heavy metals. The bad news is that it cannot be removed by boiling.

Chemical Dechlorination Products

Chemical dechlorination products are usually used by aquarists. These products are able to remove both chlorine and chloramine by breaking the bond between chlorine and ammonia. 

Unfortunately, some of these products cannot get rid of ammonia, so in order to make sure your water is chlorine, chloramine and ammonia free, it is recommended to use a separate detoxifying product as well. 

Carbon Filtration

Professional carbon filters are the most popular and most efficient filter systems for chlorine treatment. They are able to efficiently remove chlorine and its by-products as well.

Most of the water filters, especially professional water filter systems like undersink or whole house filters, usually contain a carbon filter media for chlorine removal.

There are 3 types of carbon filter media you can choose from:

  1. Activated carbon filters: they are made from raw organic materials such as coconut shell or wood. They are available in two forms, in carbon block and granular activated carbon. Both of the filters are able to remove up to 99.99% of chlorine from your water. Alongside removing chlorine and its by-products from your water, they also treat taste and odour issues.
  2. Ceramic filters: ceramic filters are considered one of the most powerful filter types. Combined with carbon filters, they are great at fighting chlorine in water.
  3. Multi-stage reverse osmosis filters: multi-stage RO filters feature carbon block and granular activated pre-and post-filters. The complexity of these filter types ensures the consumer of chlorine-free water.

Vitamin C

Did you know that you can use Vitamin C to neutralize chlorine in your water? The two forms of Vitamin C, ascorbic acid and sodium ascorbate, are great options when it comes to water dechlorination.

It is a safe and environmental-friendly alternative many professional filters rely on. To learn more about our Vitamin C based water filtration systems, navigate to our webshop or check out our products linked below!
