What Is Chloramine?

Chloramine is a mixture of chlorine and ammonia, which is added to the water of many cities as a substitute for free chlorine. It is often referred to in the plural, as chloramines, because it can take on a number of forms according to the pH and mineral content of the water. Read more about Chloramines

What Type Of Water Filter Removes Chloramines?

The use of monochloramine as a primary disinfectant in a municipal water supply presents specific removal issues due to its low degradation rate. This means that the disinfectant will be persistent and have a long life within a municipal water supply. This has prompted KDF Fluid Treatment, Inc., to investigate the use of its products as a reductant for monochloramine in potable water.

Decreasing the bulk pH of the solution increases the acidity in the vicinity of the mediums surface that can then facilitate monochloramine reduction. The presence of a metal ion that can be precipitated as a hydroxide can have this effect. This is the basis of the KD 85 mechanism by which KDF Process Media reduces monochloramine.

CuZn uses a KDF85 water filter, which breaks the bond between chlorine and ammonia that is used to make chloramines. Once the chloramines are reduced to chlorine and ammonia, they are easily removed.

NOTE: In addition to the products listed on this page, CuZn also makes chloramine reducing water filters for the shower, bath tub, washing machines, garden hoses and RVs.

With respect to drinking water systems, the CuZn Double Cartridge Chloramine Water Filter also includes a combination of trace minerals (copper and zinc in the patented form of KDF55, which meets NSF standards 42 and 61) and the highly rated acid washed coconut shell carbon, which removes more than 600 contaminants from water, including chlorine lead, heavy metals, trihalomethanes (THMs), herbicides and pesticides much the same as Nature uses the earth and its minerals to cleanse water. (Unlike carbon-only filters, bacteria can't grow inside the bacteriostatic CuZn filters!)

The CuZn Refillable Countertop Double and Triple Cartridge Chloramines Water Filters are also excellent in situations where sulfur and iron are present and a CuZn Whole House system is not feasible. Sulfur and iron expends the media more quickly than other contaminants, so refilling the system is economical and environmentally responsible.
