What is the Best Way to Remove Chloramine from Water?

What is Chloramine in Water?

The majority of the tap water supply in America has been treated by chloramine in the recent years. Just like chlorine, chloramine is a type of disinfectant added in water supply to improve drinking water quality and remove the harmful components. Chloramine is used to kill bacteria, viruses, and protozoan by breaking down their cell walls. This prevents them from causing diseases such as diarrhea, cholera, hepatitis, and typhoid. Since bacteria, viruses, and protozoa are too small for filters, there’s no physical or chemical-free method of handling these tiny contaminants in public water supply.

Why Should I Remove Chloramine from Water?

EPA has strictly regulated the amount of added chemicals. Below that limit, the benefits of using chemical disinfectant outweighs their potential risks. Despite this, we can’t ignore the so called “insignificant” potential risks.
The major concern of chloramine in drinking water is its effect on human health. Chloramine will cause respiratory problems and increase asthma risks. While it may not have significant physical effects on normal people, it causes immeasurable damage to people with respiratory issues. Chloramine produces a vapor when it reacts with the air, which may be harmful to breathe for people with a defective respiratory system. In most cases, when we make contact with low levels of chloramines, we feel itchy on the skin.
Asides from the direct health effects, chloramine also changes the properties of water. If water supply passes through copper or lead water pipes, chloramine would trigger the release of these harmful heavy metals into the water. Drinking this kind of water is clearly harmful to the body. What’s more; chloramine can deteriorate rubber and plastic, and corrode metal. These two components are found in all our faucets, shower heads, toilet valves and other in-house appliances and fixtures.
Although it’s allegedly safe to drink water that contains no more than 4 milligrams of chloramine per liter, everyone would avoid contact with chloramine of any amount considering the possible health risks involved.

How to Remove Chloramine from Water?

There are various ways of removing chloramine from water. Carbon filtration is an effective way to absorb the various contaminants in water, including chloramine. Chloramine in water is absorbed when water passes through the filter, sticking to the surface of the filter media. The larger the carbon contact surface in the filter, the better the filtration performance. However, over time, contaminants may block the pores on the filter media, leading to poor water flow and degraded filtration performance. Changing the filter according to the service life quoted by the manufacturer will fix this problem.
Catalytic carbon is a type of activated carbon with an improved capacity for contaminant removal. Catalytic carbon is often found in whole-house filters. You can install a whole house filter system to achieve preliminary filtration. This product can help you reduce most chloramine in water at the first line, giving you a clean, safe, and chloramine-free water for showering or washing.
The reverse osmosis filtration is a high-tech water treatment, considered to be the most effective water filtration technology out there. Waterdrop G3 reverse osmosis system features a 0.0001-micron pore size, which is 100,000 times smaller than the diameter of a human hair. Thanks to the tiny pore size of the RO membrane, the RO water filtration system can effectively remove various impurities larger than that size in water. This means that only water particles can pass through the RO membrane. It’s thorough not only for chloramine, but for eliminating several other common contaminants.

Frequently Asked Questions

Does Boiling Water Remove Chloramine?

Yes, but partially. You could remove chloramine by boiling water. However, the problem is that the chloramine can’t be removed completely. During the boiling process, it would release chloramine gas into air continuously, increasing the amount of time required until the last volume of chloramine is converted to gas. Therefore, it’s easier and more effective to install a water filter to remove chloramine than boiling the water.

Will chloramine evaporate from water?

Unlike chlorine, chloramine will not evaporate from water. Chloramine is much stronger than chlorine and it takes longer to react. This is why you need a powerful filter, specifically created to remove chloramine from drinking or showering water.


Chloramine is a dangerous component of public water that many people tend to ignore. The exposure of the skin to chloramine causes skin allergy and respiratory issues. Considering how powerful it is, only the right filter can effectively and completely remove it from water. So, don’t hesitate to install a water filter. Nothing is more important than protecting your health.
