If your water has a slight greenish color, or if it has a “swimming pool” smell, it may contain high levels of chloramines. Chloramines are commonly used as a water disinfectant, but many people find that these chemicals make their water taste and smell bad. If you want to remove them from your home’s water, you’ll need a special chloramine filter designed specifically for this purpose. Talk to the Certified Water Specialists at 1-800-608-8792 to find the right filter for your home’s water needs.

Chloramines are a group of three closely related chemical compounds that contain both chlorine and ammonia. These compounds – specifically one called monochloramine – are used by an increasing number of municipal water treatment systems as an alternative to chlorine for water disinfection. Although not as effective as chlorine, chloramines are more stable and don’t produce as many potentially hazardous byproducts. Because these compounds are more stable, however, they also stay in the water system for a longer time and are more difficult to remove. Chlorine can be removed from water relatively easily with an activated carbon filter, for example, but this method does not remove significant amounts of chloramine.
While the U.S. Environmental Protection Agency (EPA) considers the amount of chloramine used in municipal water supplies to be safe, it is toxic to fish, reptiles, and amphibians. Chloramine-treated water should also not be used in kidney dialysis machines, as it can cause hemolytic anemia. There is also some evidence that the byproducts of these compounds are carcinogenic, meaning that they can cause cancer.
One of the challenges of treating water that has chloramines added is that these compounds cannot be removed with standard granular activated carbon (GAC), reverse osmosis, aeration, boiling, or distillation. A GAC filter is one of the most common methods for removing chlorine from drinking water, but it isn’t very effective as a chloramine filter. Since many pitcher and faucet water filters use GAC, many people may not realize that their filters are not removing all of the contaminants that they think they are.
The most effective chloramine water filter uses catalytic activated carbon as the filtering medium. Catalytic carbon is a form of GAC that has been specially treated to change the structure of its surface and promote chemical reactions. When water that contains chloramines comes into contact with the catalytic media, the carbon acts as a catalyst to cause the compounds to decompose. The catalytic carbon used in US Water Systems chloramine filter systems is made from coconut shells.
Because catalytic carbon is a form of activated carbon, it is also effective at removing chlorine, pesticides, and many organic contaminants. A backwashing whole house chloramine filter can provide treated water for every faucet and appliance in your home with low maintenance requirements. Backwashing filters wash the carbon media periodically so that it can be used again and again for years before it needs to be replaced.
While activated carbon – and catalytic activated carbon in particular – is very effective at removing chlorine, chloramines, and other organic pollutants, it is not as effective at removing other contaminants from your water. Depending on what’s in your water, you may want a complete home water treatment system that includes a reverse osmosis filter. Reverse osmosis (RO) is the gold standard for treating a wide range of water problems, and it can be much more effective when combined with a chloramine filter. Chlorine can destroy RO membranes, so carbon filter pre-treatment is important for the system to function at its best.
