People have been adding fluoride to public water systems to help prevent tooth decay since the mid-1940s. Yet, chronic consumption of elevated levels of fluoride can have severe consequences such as abdominal pain, muscle spasms, and symptoms of skeletal fluorosis. There are a few steps you can take to start removing fluoride from your water supply starting today. Read on to learn about why fluoride is in our water supplies and how to remove fluoride from water at home.

Why Do They Treat The Water With Fluoride Anyway?

If you live in the United States, there is a good chance you regularly ingest fluoride through the water you drink. As of this year, there are more people drinking water treated with fluoride here in the US than anywhere else in the world.

Adding fluoride to water began in response to research that showed a correlation between low levels of tooth decay and high levels of fluoride in the public water supplies. From these studies, the idea that ingesting fluoride reduced cavities became popular in the general public. Since then, many developed nations have committed fully to the process of water fluoridation. This process is essentially the controlled adding of fluoride to the public water supply to improve overall dental health.

Fluoride in Your Drinking Water? How Bad Can it Really Be?

While a recent study published by International & American Associations for Dental Research confirmed that water fluoridation is linked to reduced incidences of dental decay in adolescents, other studies have indicated that the substance can actually do more harm than good. The most notable being the one published in the Harvard Public Health Magazine which claims that investing too much fluoride can result in negative effects on the brain and memory.

Medical studies continue to emerge that confirm these statements. Most show that elevated levels of fluoride in public water supplies lead to other systematic consequences for the body, such as mild symptoms of eroded tooth enamel, nausea, and vomiting. It can also even cause some significant symptoms such as debilitating joint pain and osteosclerosis. None of which sounds pleasant to experience merely from having a few glasses of tap water each day.

Additionally, som less common health concerns include:

  • Brain damage
  • Bone disease
  • Thyroid problems
  • Can impede the growth of the fetus in the womb
  • Acne
  • Lower fertility rate

With all this research, recent efforts have been made by The Health and Human Services Department and Environmental Protection Act to lower the fluoride levels in drinking water. Till this becomes the accepted standard, it’s really up to us to take matters into our own hands and filter fluoride from our water. So, how do we go about ensuring our tap water is free from fluoride?

How to Remove Fluoride From Water Safely and Cheaply?

Most people who are concerned about the levels of fluoride in their water supply choose to use an at-home filtration system to solve the problem. There are a range of filters that will do the trick, from jugs to home-wide systems. Depending on how much you care about removing the fluoride, you may decide that one of these systems is best for you. For instance, if you want to save money and you only care about fluoride in your drinking water, a filter jug should be sufficient.

But, as you may have guessed, this fancy water filtration system can be on the pricey side. The cost of an RO system varies depending on size specifications. It also depends on how much water you consume as a household and where you install the filter.

Under-the-Sink System

Another common approach is to choose to install an under sink water purifying system to avoid paying thousands of dollars required to set up an entire home water purification system. The benefit of using an under-sink filter is that installation is relatively quick and easy.
