Yes as mentioned in the article unfortunately boiling does not remove fluoride out of water. However this method actually increases concentration because as the water boils the vapors escape and leave the mineral behind. While boiling water can remove some impurities from your water the process has been shown to increase the concentration of fluoride salt.
One of the most frequently asked question is on whether boiling tap water removes fluoride. So you may well be wondering whether you can perform your own distillation in your free time at home. As the volume of water decreases through boiling the fluoride concentration actually goes up.
Boiling your water wont help as the fluoride does not evaporate easily like chlorine. In the end boiling water does not remove fluoride from water. Boiling will actually have an adverse effect.
To top it all off fluoride is difficult to remove from water. Boiling does not help remove fluoride from water because fluoride does not evaporate easily.
