Chlorine is bad stuff. It causes skin irritation, makes swimming difficult, and even kills fish.

Introduction Transition and thesis: Does boiling water remove chlorine? Yes, it does! In fact, boiling water will completely eliminate any traces of chlorine from tap water.

If you want to make sure your drinking water doesn’t contain harmful levels of chlorine, then read this guide. We’ll talk about why chlorine is bad, and how boiling water removes it. Then we’ll see exactly how easy it is to boil water yourself.

What is Chlorine?

According to the Centers for Disease Control and Prevention (CDC), chlorine is a chemical element belonging to a group called halogens, and when chlorine reacts with sodium, salt is formed. Sodium chloride (table salt) is the main product of this reaction.

Most municipalities add chlorine as a compressed elemental gas, sodium hypochlorite solution (NaOCH3), or solid calcium hypochlorite (Ca(OCl2).

At high concentrations, chlorine is a choking, toxic gas, that would burn your lungs, and kill you in fairly quick order if you were not able to get away.

However, when any form of chlorine is mixed with water, hypohalous acid (HOCl), is produced, and this produces disinfection.

At low concentrations, chlorine is beneficial to health and helps prevent diseases.

What is Chloramine?

Chloramines are compounds containing both chlorine and ammonia. They are used to treat drinking water because they are less corrosive than chlorine alone.

The most common type of chloramine found in drinking water is monochloramine (NH2Cl). This compound has been shown to be more effective at killing bacteria than chlorine itself.

How Do You Check Chlorine Levels in Your Water?

Chlorine is a common household contaminant found in tap water. You may be wondering how to tell if your water has chlorine in it. Here are some tips to help you figure out whether or not your water has chlorine in its system.

First, you should test your water using a pool test kit. These kits come in various forms, including tablets, liquids, and strips. Simply drop a couple of drops of the solution onto your water and wait for the color to turn yellow. If the color turns yellow, then your water does indeed have chlorine in it.

Another option is to use a color test kit. These kits work similarly to pool test kits, except instead of changing the color of the water, they cause the color to change to a specific shade of pink. Again, if the color turns pink, then your water does have chlorine in it. However, keep in mind that this test will not detect free chlorine levels.

Finally, you can use a digital colorimeter. These devices use two different methods to determine the presence of chlorine. First, a DPD tablet (a form of chlorine) is added to the sample. Then, the device measures the light reflected off the surface of the water. If there is chlorine present, the light will reflect differently than without it.

In conclusion, these are the three main options available to you when determining whether or not your water contains chlorine. All three tests give accurate results, but they are slightly different. Therefore, you should try all three before deciding which one works best for you.

Why Do We Put Chlorine in the Water?

Chlorine was originally used to purify drinking water. It was first introduced into municipal water systems in the United States in the late 1800s. The reason why chlorine is used is that it kills microorganisms such as bacteria and viruses.

Is Chlorine in Your Water Harmful?

Chlorine is widely used in our daily lives. We use it to clean our homes, wash our clothes, and keep us healthy. But did you know that there’s a limit to how much chlorine we should consume?

According to the EPA, the amount of free chlorine allowed in drinking water is between 0.5 – 4 mg/L or 0.05 – 4 ppm. At this level or lower the chlorine used to disinfect drinking water is unlikely to cause any long-term health issues. However, if you drink water containing high amounts of chlorine over a long period of time, it may lead to health problems.

Does Boiling Water Remove Chloramine?

Chlorine is highly volatile, meaning it will eventually escape from the water. And since it’s highly volatile, raising the temperature increases the amount that can evaporate in any given amount of time.

So if you want to remove chlorine from your tap water, you should boil it for 20 minutes or longer. But if you only have a small amount of water, boiling won’t be enough to remove a lot of chlorine.

For larger amounts of water, though—like the amount in a bathtub or sink—boiling isn’t a viable option. You’d need to heat the entire volume of water for a long time, which would require a lot of energy.

Instead, you can buy a filter that removes chlorine from tap water. These filters work by passing water through activated carbon, which binds with chlorine molecules.

What About Boiling Out Dissolved Chloramine?

In order to boil off the chloramine, you need to heat the water until it reaches 212 degrees Fahrenheit or 100 degrees Celsius. And since boiling water requires energy, it will take a little bit of time to boil off the Chloramine.

But here’s the catch – it won’t happen overnight. You’ll need to boil 10 gallons (38 liters) of water for at least one hour to completely remove 1 milligram per liter (mg/L) of chloramine.

But there is a solution. You can buy a filter that removes chloramines from your tap water. One example is the AquaPure Water Filter System. It uses activated carbon to remove chloramines from your tap water.

How Much Chlorine Does Boiling Remove?

You can boil water for less than five minutes or for longer periods of time depending on how concentrated the chlorine is in your water.

If you have ten gallons of water to boil, then you need to heat the water for 3.5 minutes to get rid of the chlorine. However, if you have only two gallons of water to boil then you need to boil it for 7.2 minutes.

So, boil your water for at least ten minutes to avoid any potential health risks.

Pros and cons of boiling water process to remove Chlorine


If your water contains only chlorine and not chloramine, you can drive the chlorine off by boiling the water for 15 minutes.


  • Faster than waiting for it to off the gas at room temperature


  • Requires a lot of energy and significant time to boil all of your water before you even start brewing.
  • Will not remove chloramine


Chlorine is an essential ingredient in water treatment systems. It helps prevent bacteria growth and keeps our drinking water safe. However, chlorine has been known to cause problems when combined with ammonia. This combination creates chloramines, which are even worse than chlorine itself.

In fact, chloramines are considered toxic by the EPA. So what does boiling water actually do to remove chloramines? Well, it turns out that boiling water removes both chlorine and chloramines. That means you can enjoy clean, fresh-tasting tap water without worrying about harmful chemicals.
