But how are you going to pick one suitable for your home while there are many options in the market? If you are not sure how to choose the right chlorine water filter, then continue reading this article.

In this post, we recommend four water filters that will remove chlorine from your water. But before taking you through those water filters, let’s have a look at the backstory of water chlorination and how it came to pass.

What is water treatment?

This is simply the use of chemicals to kill germ in water, making it safer for drinking, recreational use, among other uses. Water treatment removes harmful substances from water and also reduces the concentration of these substances making water safe for use. Basically, water is treated to removed substances such as algae, viruses, bacteria, fungi, minerals and solid.

What is water-chlorination?

Water chlorination is the use of chlorine or hypochlorite in water to kill certain bacteria and microbes. Chlorine is effective in removing these microbes because it is highly toxic to them.

The history of water chlorination

The use of chlorine to treat water is dated back in the early 1900s. The first use of chlorine gas to treat water happened in Middlekerke, Belgium, in 1903. Before then hydrated line and bleaching powder were used to disinfect water.

In 1908, the city of Jersey City became the first city and state in the US to perform a full-scale treatment procedure using sodium hypochlorite. In the same year, the Bubbly Creek firm also started the same process in Chicago. This time, using chloride-of-lime.

Chlorine gas was compressed in a steel cylinder by C.R. Darnall in 1910, and since then it has been the common method of treating water. Four years later, the US Department of Treasury set up standards calling for a maximum bacterial concentration of 2 coliforms per 100ml of water. This required effective disinfection and the outcome was the massive use of chlorine to treat water.

By1930s, this treatment procedure had prevented all health conditions associated with water diseases in the US.

The positive effects of water chlorination

  • Reduction of bacteria and viruses: As said above, adding chlorine to water helps reduce the concentration of bacteria and viruses in water. This means, if you add it in your drinking water, you are less likely to suffer from typhoid or cholera.
  • Residual protection against re-contamination: Once added, the chlorine mixture does not drain away fast, and this results in residual protection. Additionally, this protection reduces the volume of bacteria and viruses in water, making water safer for drinking and other uses.
  • Scalability and low cost: Chlorine production is done on a large scale, and the material used to produce it is abundantly available. The availability of materials makes it cheap to produce chlorine and its by-products. Additionally, the large production of chlorine has made it possible for treatment plants to use chlorine for water treatment.

Negative effects of water chlorination

  • Chlorine lowers disinfection effectiveness in turbid waters.
  • Chlorine offers relatively protection against protozoa. This means you can easily catch amoebic dysentery among other health conditions.
  • Quality control of the solution must be observed.
  • It can reduce the lifespan of many appliances, such as, rubber gaskets to wear down and crack.
  • Chlorine dries out your skin and hair, prone to itchy and being brittle.
  • Chlorine gives water a bad taste and odor. You may have noted this when drinking or using chlorinated water for cooking or bath.
  • There are potential long-term effects of chlorine by-products. For example, Trihalomethanes (THM), which is a result of chlorine combining with organic matter, is very toxic when consumed in water or inhaled as water vapor when bathing.
  • Chlorine, either through drinking, swimming, or even showering may increase your rick of developing asthma.
  • The reason why your clothes color fades is because of chlorine, even if you are not adding any bleach and even if you are using any color-preserving detergents.

Should We Worry About Showering in Chlorinated Water?

Chlorine is known to react with certain natural organic matters to produce toxic by-products, known as DBPs (toxic disinfection by-products). Not long after these DBPs were discovered in chlorinated drinking water in the mid 1970s, along with a potential risk of bladder cancer and an elevated risk of miscarriage, the US government established new guidelines for the use of DBPs. This dramatically changed the operation of water treatment plants, and led to a cessation of chlorine use in some areas.

In a study in Science magazine, authors, David L. Sedlak and Urs von Gunten question whether or not this decision now poses a public health risk.

Over twenty years ago, Ian Anderson, writing in New Scientist was warning that hot showers were a health risk. At a meeting of the American Chemical Society in Anaheim, Calfornia, in September 1986, he presented research that showed there was a greater exposure to toxic chemicals via inhalation of chemicals than via drinking the water. The amount of chlorine absorbed during a ten minute shower, he said, was equal to drinking about nine liters of chlorinated tap water.

“The chemicals evaporate out of the water and are inhaled. They can also spread through the house and be inhaled by others. Householders can receive six to 100 times more of the chemical by breathing the air around showers and bath than they would by drinking the water.”

Janet Raloff, writing in Science News, claimed that the National Academy of Sciences estimated that 200 to 1000 people die each year in the US from cancers caused by contaminants in water. She goes on to say: “The major health threat posed by these pollutants is far more likely to be from their inhalation as air pollutants. The reason that emissions are high is because water droplets dispersed by the shower head have a larger surface-to-value ratio than water streaming into the bath.”


As much as adding chlorine has some benefits, it is good to understand that you need to remove that it. Otherwise, be prepared to visit your doctor now and then for treatment. Hopefully, this post was helpful.
