Chloramines Water Filters - reduces chlorine and chloramines taste and odor
In the past few years, many municipalities have been adding chloramines to the water along with chlorine to kill bacteria and cysts. Chloramines are a combination of chlorine and ammonia. They prevent THMs (trihalomethanes) from forming when mixing with organics in the water, and have a longer life than chlorine alone. Unfortunately, chloramines are not as easy to remove as chlorine--they require a longer contact time with the media, and not everything can be removed, mainly the ammonia. Fortunately, the ammonia levels are very low in the neighborhood of parts per billion. Even reverse osmosis won't remove it. One solution offered by an engineer at Calgon Carbon, the manufacturer of catalytic carbon designed to reduce chloramines, is to add triple the amount of chlorine to your water which would change the chloramines and the ammonia would be removed. But this isn't a practical solution for drinking water filters. Ammonia, even in very low levels, is a problem for tropical fish owners and those with Coy ponds. The chemical Zeolite will reduce ammonia, and is available with some whole house filters, however, cartridges are not available.
Our KDF/GAC filters will reduce the chloramines taste and odor. However, we found a specially designed Catalytic GAC carbon filter that will reduce more of the chloramines taste and odor than other types of carbon filters (about 90 percent), so we are now offering that cartridge as an option in our water filter systems. As an alternative, our double filters: under-counter Model UCD-CB and countertop Model CTD-CB will also reduce chloramines taste and odor. They use our KDF/GAC cartridge as a pre-filter followed by a 0.5 micron extruded carbon block cartridge. But in comparision, the catalytic carbon is more effective. Also, KDF media (copper/zinc), on its own, has a reduction effect on the chloramines as found in a study from KDF Fluide Treatment, Inc entitled: Reductive Dechloramination: Finalized Study of KDF®85 Process Medium in Point-Of-Entry and Point-Of-Use Applications.
In spite of what you may have read on the Internet, carbon block filters alone do not effectively remove chloramines. But Catalytic Carbon GAC (granulated activated carbon) in a special formulation, manufactured by Calgon Carbon, is effective in reducing chloramines taste and odor in a single cartridge. Extruded carbon block filters alone will only reduce some of the chloramines. However, if you use a combination of GAC and carbon block filters and move the water through the filters at a slower rate, you can reduce the chloramines.

Model CTD-CH - Designed for municipal water that contains a high level of chloramines and chlorine. This dual housing countertop filter features our KDF/GAC cartridge and a high performance granulated activated carbon cartridge designed for maximum chloramines taste and odor adsorption. It's protected against bacteria by the KDF/GAC cartridge. A diverter valve replaces the aerator on your faucet. In the regular position, water is sent through the aerator. For filtered water, turn on the cold water and rotate the plastic diverter valve knob (now a new more durable, long lasting, valve) - water is sent through the filter and out its own spout; a long reach lead free spout allowing for placement flexibility on your countertop.
