As a necessary evil, chlorine and chloramines kill bacteria in your drinking water.
While we do need a method to reduce the risk of bacteria, chlorine and chloramines cause water to taste bad and recent studies have even found them to be harmful to your health.
Typically chlorine is treated by using carbon filtration, however if your city water supply treats with chloramines, make sure the specific filter you have will reduce both.
Your local Culligan Man will be able to let you know specifically what’s in your water and the right way to treat it the first time so you don’t have to waste time and money on a filter that doesn’t solve your water unique problems.
