How to Remove Fluoride from Water
Fluoride is a fluorine compound that occurs naturally in water, rocks, soil, teeth, and other body tissues. To strengthen enamel (the outer layer of your teeth) and prevent cavities, fluoride is frequently used in dentistry.
How does fluoride get into the water?
Because it works well at preventing cavities and at enhancing and maintaining oral health, fluoride is added to water.
The fluoride content of water is almost always adjusted to 0.7 milligrams per liter by many municipalities because naturally occurring fluoride levels are typically too low to prevent tooth decay. According to the Centers for Disease Control, 0.7 mg/L is the ideal amount of fluoride in drinking water to prevent tooth decay in both children and adults (CDC).
Researchers discovered that residents of areas where fluoride was naturally present in the water had fewer cavities, so community water fluoridation was implemented.
In Grand Rapids, Michigan, fluoride was purposefully added to the water supply in 1945 as a sort of experiment, but it was so successful in enhancing the oral health of the community that water fluoridation quickly became the standard. Today, fluoridated water is provided to about 75% of American homes.
What fluoride levels in drinking water are considered safe?
According to the Environmental Protection Agency, fluoride levels in drinking water should be 4.0 mg/L or lower. The Maximum Contaminant Level for fluoride in drinking water provided by public water systems was set by the EPA at 4.0 mg/L.
The recommended level of fluoride in water is 0.7 mg/L, though. Children’s risk of developing dental fluorosis increases at levels greater than 0.7 mg/L (a cosmetic condition characterized by stained or discolored teeth).
What negative effects does fluoride in water cause?
Fluoride in water can have both good and bad side effects. The amount of fluoride in public water systems is too low, so it is highly unlikely that community water fluoridation will have a negative impact on your health.
According to the CDC, community water fluoridation is safe, effective, and has no adverse health effects other than dental fluorosis. This is still supported by scientific research.
However, there are significant geologic fluoride deposits in some parts of the world, including large portions of Asia and Africa, which can contaminate water supplies. A person can also be exposed to harmful levels of fluoride through industrial chemicals, though this is uncommon. These kinds of situations can result in a high fluoride intake, which has been linked to the health risks listed below.
Fluoride in water benefits:
- There are fewer cavities, but they are more severe.
- restores damaged tooth enamel
- reverses tooth decay’s early symptoms
- stops the development of harmful oral bacteria
- Fewer tooth extractions and fillings are required.
Dangers of fluoride in drinking water:
- Dental fluorosis is a cosmetic condition marked by discolored, stained teeth brought on by children and infants receiving too much fluoride.
- Skeletal fluorosis: When excessive amounts of fluoride build up in bones, it can cause stiffness, muscle weakness, and joint pain.
- Hypothyroidism is an underactive thyroid that can lead to weight gain, dry skin, increased sensitivity to cold, and fatigue.
- lowered IQ
How to Remove Fluoride from Drinking WaterReverse osmosis, distillation, activated alumina filters, and bone char carbon filters can all get rid of fluoride from drinking water.
Osmosis in reverse
Through reverse osmosis, unfiltered water is forced through a semipermeable membrane under pressure. Water molecules are small enough to pass through the membrane’s microscopic pores, but impurities like fluoride get caught. On the other side, only pure, filtered water appears.

The process of distillation purifies water by simulating the way that water is naturally cleaned: by evaporation in the atmosphere. Because steam cannot assume a gaseous state like water can, fluoride and other contaminants are removed during the water distillation process. The water is clean once it has reverted to a liquid state.

Aluminum oxide exists in the solid, porous form of activated alumina. Fluoride and other contaminants are absorbed by activated alumina granules as water passes through a filter made of this material, allowing clean water to pass through to the other side.
Although they are most efficient at removing fluoride from water with a pH between 5 and 6, activated alumina filters only function in solutions with a pH of less than 8.5. Water flow rates must also be very slow because they need a long contact time to work.
filters with bone char and carbon
One of the earliest techniques for removing fluoride from water was the use of bone char carbon filters. Bone char filters are made by heating animal bones to extremely high temperatures, which improves the carbon’s adsorption capabilities. Standard activated carbon filters do not remove fluoride.
Fluoride is either absorbed or changed by adsorption when water passes through a bone char carbon filter; clean water comes out the other side. Even heavy metals like lead and chlorine can be eliminated by using bone charcoal filters.

Is fluoride removed from boiling water?
No, fluoride is not eliminated by boiling water. Fluoride concentrations will rise as a result of boiling because some water evaporates during the process.
Does Brita purify fluoride?
No, fluoride is not removed by Brita filters. Fluoride cannot be removed by Brita filters, so your water’s fluoride levels will not be reduced.
Do you fluoridate your water?
By asking your municipal water provider or using the CDC’s online My Water’s Fluoride tool, you can determine whether your water has been fluoridated. Not every American city’s drinking water is fluoridated.
Although each city has the right to decide, you can find out if your water is fluoridated and how much fluoride is added by checking with your municipal water provider or using the CDC’s online tool.
Does bottled water contain fluoride?
There may be fluoride in bottled water. Your choice of bottled water will depend on its brand and original water source. The original water source may have naturally occurring fluoride, or a municipality may add it.
Since many bottled waters are made from municipal water sources, they may also contain fluoride if the municipality fluoridates its water. We advise asking the manufacturer of the product you like if it contains fluoride, because it will only be listed on the label if it was added during the bottling process.
