How To Remove Fluoride From Water

For over 70 years, fluoride has been added to the public water supplies across the United States. Scientists discovered people that lived in areas where fluoride was naturally a lot more relevant in the water, they had much fewer cavities.

How To Remove Fluoride From Water

Still today, the American Dental Association (ADA) has advocated fluoride in water as it is believed to reduce tooth decay in children and adults in almost 25% of cases. 

In this article, we will be discussing more about fluoride and how to remove fluoride from your water.

Fluoride In Your Drinking Water

Adding fluoride to drinking water started out with just one supplier doing it in small areas, during the 1940s. Now, around 67% of all homes in America are believed to receive water that contains fluoride.

The level of fluoride in your water is never to be higher than 0.7 mg/L, to reduce any risks of causing fluorosis in children.

However, some people have started to wonder whether naturally having fluoride in drinking public water is such a good thing anymore. This is because there are some effects of having fluoride in water that are now coming to light.

Effects Of Having Fluoride In Your Water

New research shows that there are various effects from having fluoride in your drinking water, and not all of them are good. The reason fluoride has stayed in public water for so long, is because it helped reduce cavities in those who drank it.

However, today, research has shown that there are some negative side effects, and maybe we should discontinue having fluoride in our water.

The following are a few of the reasons we may want to consider having fluoride in our water.

  • Once fluoride is added to the water supply, there isn’t a way to be able to control the concentration and dose of the fluoride. Therefore, there is no way to regulate how much someone should be having due to their weight, age, and health etc.
  • In low doses, fluoride is believed to have some toxic properties. 
  • The majority of children are receiving and ingesting much more fluoride than their daily intake suggests they should be having. 
  • A recent study, in the UK, has suggested that fluoride in water may be linked to the increased risk of someone developing an underactive thyroid or hypothyroidism.

How To Remove Fluoride From Your Water?

Reverse Osmosis

The best to remove fluoride from your water is by using filters, in particular a reverse osmosis filtration system. It is believed that by using this filtration system, you can remove around 95.2% of your fluoride in your water.

The reverse osmosis filtration system will use the water pressure in your homes to push the tap water through the filtration cycle. Your tap water will go through a semipermeable membrane and additional filters.

These additional filters help to remove many contaminants, including fluoride.

Other contaminants that you can reverse using this filtration system includes:

  • Lead,
  • Chlorine,
  • Cadmium,
  • Sulfates,
  • Detergents,
  • Asbestos.



Distillation is a very effective and affordable fluoride removing method. Your water will be heated, and the steam will evaporate and be captured into another container.

With this method, all impurities including fluoride will be removed and left behind. The vapors that have been collected then transform back into distilled water as it cools down.

Activated Alumina

Activated alumina is a solid and porous form of aluminum oxide. The activated alumina will absorb contaminants like fluoride out of the water. However, alumina filters will only work with water that has a pH 8.5 or below.

When it comes to removing fluoride, the pH of the water should be either 5 or 6. Then as the water goes through the filter, the impurities will be absorbed, and a pure water will be left behind to drink and use.

Bone Char Carbon

Using bone char carbon is one of the oldest methods around, this is used to remove fluoride contained water. Bone char carbon is used in water filter cartridges, which will remove around 90% of any mineral content in the water.

However, this isn’t a great method to be done at home, as it isn’t easy to do. In addition to that, this method would be suitable for vegans. As bone car is created by animals bones being heated to very high temperatures.

Ineffective Methods Of Removing Fluoride

There are some methods that people believe will remove fluoride, yet really they are very ineffective. A lot of people know that when you boil water it will remove organisms including bacteria.

Therefore, people may assume that if you just boil tap water, that it will remove fluoride that is present.

Yet actually when you boil water you are increasing the fluoride concentration in the water, because as the water gets hotter, vapors leave and the mineral is left behind.

Even some home filters that may attach to a pitcher or your faucet, don’t always remove all the minerals, such as fluoride. In this case, these filters remove visible contaminants and will improve the flavor of the water, but fluoride is still present.

A lot of people avoid tap water all together and will buy bottled water. However, bottled water isn’t an environmentally friendly solution. Therefore, we wouldn’t recommend this option.

Final Thoughts

For a long time, fluoride was seen as a great thing, as it helps reduce cavities in adults and children. Yet more research has shown that fluorine in our water can have many negative effects on our health.

As a result, more people are now trying to remove fluoride from their water.

In this article, we have given you various ways in which you can remove fluoride from your drinking water. In addition, you should now understand the effect’s fluoride has on our bodies.
