Can refrigerator water filters remove fluoride and chloride?


Refrigerator water filters are carefully designed to remove contaminants in the tap water such as minerals, chemicals, bacteria and other microscopic organisms that can cause funny taste and harm to people’s health. But can they filter out fluoride and chloride? In this post, I will try to give you the right answer.

Firstly, let’s learn something about fluoride and chloride.


Fluoride is found naturally in soil, water, and foods. Adding it to tap water can significantly reduce the occurrence of tooth decay. However, excessive fluoride can cause dental fluorosis or skeletal fluorosis. It cannot be removed by the act of boiling tap water.


Chlorine is often used by American water supply authorities as a disinfectant to kill bacteria and other microorganisms in the tap water. Usually, it is very effective as disinfectants, but it can remain in the tap water if no further measures are made. Chlorine can make water taste and smell bad, and many people find that it can cause skin irritation.


Coconut shell activated carbon is widely considered to be great for removing fluoride and chlorine from tap water. As the untreated water passes through the carbon, fluoride, and chloride get caught in the tiny pores in a process called adsorption.

For a cleaner and safer drinking water, we also recommend you to replace your filter at least every six months or every 200-300 gallons of water. The longer your filter work, the more fluoride, and chloride could cover the carbon, affecting the filtration results.


The fact we would like to remind you is that not all refrigerator water filters are effective at removing fluoride and chloride, so you must be careful while choosing filter brands.
