Worried about chlorine in your water? Today, we recommend 4 of the best chlorine water filters available. We also discuss the backstory of water chlorination, and how it came to pass.
Chlorine is knowingly added to water supplies to prevent bacteria from growing. The chlorination of water began long ago when illnesses like typhoid, cholera, and dysentery were commonplace. However, chlorine itself is actually very toxic. Chlorine gas is even used as a chemical weapon, and has been labeled as a “choking agent”. Furthermore, chlorine in water is known to combine with organic matter to form harmful Trihalomethanes (THMs). These have been linked with negative health effects, including cancer.
So, what can we do to limit our exposure to harmful chlorine?
Well, one of the most effective ways to combat chlorine is by using a water filter.
In this post, we recommend 4 of the best water filters that remove chlorine.
The four types of water filter that we recommend are:
- A reverse osmosis system that is incredibly effective in removing over 1000+ harmful contaminants.
- A whole house system that will filter all of your household water (drinking & bathing).
- A water filter pitcher that is less expensive and requires no installation
- A chlorine shower filter that will protect your skin, hair, and lungs.
Read on to find out more about the best water filter for chlorine removal.

This model has some of the best chlorine shower filter reviews we have seen. But, best of all it is really attractively priced.
Water Chlorination: The Backstory
Water chlorination divides opinion. Let’s take a look at the facts to see whether you should be concerned or not.
What is Water-Treatment?
This is a process that involves the use of chemicals in order to kill germs making water safe for drinking, industrial uses, and recreational uses among others. The process helps to remove contaminants and reduce their concentration making water it safer for use. When water is treated, substances removed include suspended solids, bacteria, algae, viruses, fungi and minerals like iron and manganese.
What is Water-Chlorination?
This is a treatment method that involves the addition of chlorine or hypochlorite in water. This is done to kill certain bacteria and other microbes since chlorine is highly toxic to them. This helps to prevent the onset of health conditions like cholera, dysentery and typhoid.
Water that is used for consumption and cooking needs to be free of micro organisms. When a person contracts any of the related diseases, it usually depends on the pathogen, number of organisms, strength of the organism and the volume ingested among others. In order to purify the water, a specific treatment called disinfection is carried out.
The History of Water Chlorination
The use of the water-chlorination procedure started back in the early 1900s and the first use of chlorine gas to disinfect drinking water happened in Middlekerke, Belgium in 1903. Previously, treatment was done using hydrated lime or bleaching powder.
In 1908, the city of Jersey City, New Jersey 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 started the process in Chicago. This time chloride-of-lime was used.
C.R. Darnall compressed chlorine gas in a steel cylinder in 1910 and this has been the most common method for treating water. In 1914, 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 which led to use of water-chlorination by treatment plants.
In the 1930s, the treatment procedure had prevented all health conditions associated with water diseases in the US.
The Positive Effects
Reduction of bacteria and viruses in water
Water has many uses in homes and industries. In homes, it is used to quench the thirst and cooking while in industries, it is used in the production of goods as well as cleaning. It is derived from many sources ranging from rivers, streams and springs.
As it flows from one location to another, it comes into contact with plants, rocks and human activity. This leads to the deposit of bacteria and viruses. Due to this, it has been found to cause health conditions like cholera and typhoid. Chlorine is toxic and when added to water, it reduces the volume of bacteria and viruses.
Scalability and low cost
The process of producing chlorine is done on a large scale and the raw materials used are abundant. This has made the production of the gas as well as the byproducts for treatment to be affordable. The large scale production of the treatment product has made it possible for treatment plants to dispense the product in the water via large pipes and tanks.
Residual protection against re-contamination
When treatment is done, the chlorine mixture added does not drain away easily and thanks to its residual protection, users cannot experience the onset of diseases. The toxic levels of chlorine itself help to reduce the volume of bacteria and viruses which are known to cause different diseases.
The Negative Effects of Water-Chlorination
- It offers relatively low protection against protozoa – this can lead to the onset of health conditions like amoebic dysentery among others.
- It lowers disinfection effectiveness in turbid waters.
- Quality control of the solution must be ensured.
- There are potential long term effects of chlorine by-products.
- Chlorine combines with organic matter to form byproducts called Trihalomethanes (THM). These are very toxic when consumed in water, inhaled as water vapor when bathing, or even applied to the skin when bathing too.
- It gives the water a bad taste and odor. This affects drinking, cooking, and bathing.
It seems, with water chlorination, that we are being given protection against one thing by something that is just as hazardous. It’s a worrying thought that something so potentially toxic is knowingly added to our water.
