Remove Chloramines from Drinking Water


          Chloramines are chlorines ugly cousin. Chloramines used in water supply treatement are essentially chlorines attached to ammonia molecules. This combination has been used more and more frequently in the past two decades to treat city water supplies to reduce the active bacteria found in the water system. Chloramine is more stable than free chlorine in the water supply and has less of a tendency to convert free floating organic materials into carcinogens. However chloramine is just as dangerous to the human body as chlorine when ingested. As such it should be removed from your drinking tap water before you drink that water or use it for cooking. Follow the tips below for the best ways to remove chloramine from your drinking water.

Step 1

Carbon Charcoal Water Filter Purchase a Granular Activated Carbon filter. Granular activated carbon filters are the only viable way to successfully remove chloramines from your water supply. There are many purchase options available for GAC filters. You can attach a faucet mounted granular activated carbon filter such as a PUR or Brita filter. In addition you can use a pitcher type GAC filter or an under the sink GAC filter. An under the sink filter attaches directly to your copper plumbing lines feeding your kitchen sink. This way all the water that comes out of your sink has been filtered to remove chlorine and chloramines.

Step 2

When you run your contaminated tap water through your carbon filter for drinking or cooking, use the slowest flow rate as possible. This means open the sink handle just a tiny amount so that the water trickles out in a small stream. This is done to allow the water to have a longer contact time with the carbon filter. The longer the chlorine filled water comes into contact with the carbon in the filter the more time it has to remove chlorine and chloramines from the water and do its job properly. If you turn the faucet on at a high flow volume and the water gushes out of your carbon filter then there is less contact time for the contaminants to adhere to the filter surface. As a result you may get more contaminants in your water than you bargained for.

Step 3

Water Filter PitcherUnlike with chlorine contaminated tap water, you cannot just let the water sit out overnight or for 24 hours to let the chloramine evaporate out of solution. With chlorine water you may have heard that you can just fill a pitcher with tap water and let it sit open in your fridge for 24 hours to let the chlorine evaporate out of the water. While this is true of free chlorine water, water that has been treated with chloramines will not evaporate out the chloramines in the same manner. Thus the only way to successfully remove chloramines from water is to filter the water through a GAC carbon filter.

Step 4

For the ultimate chloramine filtration ability try a two step filtering process. For example use a GAC carbon faucet mounted or under sink mounted filter for your first line of defense. Then purchase a pitcher carbon filter and pour the already carbon filtered sink water into the pitcher filter to essentially filter it a second time. This should remove close to 99% of all the contaminants that the carbon filters are rated to remove because you have now double filtered the water. This is the ultimate line of defense to remove as many of the impurities in the water as you possibly can.
