It depends on the type of refrigerator water filter. Some refrigerator water filters are designed to remove fluoride from water, while others are not.
Fluoride is a naturally occurring mineral that is commonly added to public water supplies to help prevent tooth decay. While fluoride is considered safe in small amounts, excessive exposure to fluoride can lead to a condition called fluorosis, which can cause tooth discoloration and other health problems.
Some refrigerator water filters use a filtration process called adsorption to remove contaminants from water. Adsorption is a process in which contaminants are attracted to and held by the surface of the filter media, allowing clean water to pass through.
However, not all types of filter media are effective at removing fluoride from water. If you are concerned about fluoride in your water supply, it is important to choose a refrigerator water filter that is specifically designed to remove fluoride in order to effectively reduce its levels and provide you with clean, safe drinking water.
You can check the product specifications or consult with the manufacturer to determine if a particular refrigerator water filter is capable of removing fluoride from water.
