What is Fluoride? 

how to filter fluoride out of water

Fluoride is a mineral found naturally in water, soil, and certain foods. It is commonly introduced in bottled water due to various health advantages, one of them being oral health. Fluoride not only helps in avoiding cavities but also promotes the growth of healthy teeth. The amount of fluoride present in different sources might differ. Water fluoridation practice of adding certain levels of fluoride to water, is a term that has been common for years. Ever since there have been reports among the general populations of emulating water fluoridation due to its effectiveness in preventing dental caries since low levels of fluoride in drinking water were traced back to the turn of the twentieth century. World Health Organization has recommended a limit of 1.5 mg/liter of fluoride in drinking water. 

Why Remove Fluoride?

If you wish to learn how to remove fluoride from water, you must first know the reasons behind such a desire. Here are different reasons some people are against the deviation of water from its natural composition by the addition of fluoride:

Health Risks

Fluoride can contribute to deformities of the teeth, as well as skeletal deformities known as skeletal fluorosis, one of the diseases that interfere with the development of teeth, the protective covering of the teeth called the enamel, among others, and bone conditions. Dental Fluorosis is classified as a restriction of normal dental development due to overuse of fluoride-containing products. It's primarily a cosmetic, unsightly staining of the enamel of the teeth.

Skeletal fluorosis is associated with a similar process in that excess build-up, hardening and lack of elasticity of bone also occurs increasing the propensity of fractures and loss of range of motion at the joints. This has been one of the reasons why the EPA has set a primary standard for the concentration of fluoride in water supplies which is also the reason why its infrequent use.

Furthermore, it is also possible for a patient to have an acute fluoride level above the therapeutic range in the community water supply. This results in nausea, vomiting, and inflammation, in some extreme cases, even death. 

Environmental Concerns

Some people oppose fluoride as they state that fluoride may seep into aquatic ecosystems and harm wildlife. 

In light of these issues, the U.S. Public Health Service suggests maintaining fluoride levels in treatment between 0.7 mg/L as this concentration is considered ideal for dental health. It prevents fluorosis to some extent. For additional fluorosis control, The United States Environmental Protection Agency (EPA, 2014) has outlined a drinking water standard that restricts the fluoride concentration in public drinking water systems to 4.0 mg/L.

Now let’s proceed to how to remove fluoride from water using affordable and natural methods.

Affordable Methods

If you are looking for the cheapest method of fixing fluoridated water, consider the following solutions.

Reverse Osmosis

  • Reverse osmosis is the best solution and is very popular even as a whole-house filter system. The reverse osmosis system features a pre-filter that removes salt and chlorine. Water from treated filters is forced into a device against a membrane that excludes certain solids dissolved in the water. This membrane can be described as being porous with a coating on one side which permits water and free ionic elements to enter the coating but not salts, organics, bacteria, and viruses from the opposite side of the membrane. 

Reverse osmosis
  • The size of the pores is typically 0.0001 microns which means that organisms such as viruses (approximately 0.02-0.4 microns) and bacteria (0.4-1 microns) cannot penetrate them. Thus, a whole-house reverse osmosis water filter system allows one to enjoy drinking purified water because it adheres to all these principles. 

  • Reverse osmosis applies to any kind of contaminant, including fluoride. It thus makes water safe for consumption. 

Natural Methods

How to remove fluoride from water for free and naturally? Here we guide you to solve how to remove fluoride from water is via distillation. 

Distillation 

  • During distillation, water is heated until it eventually boils and vaporizes. Since impurities like fluoride do not evaporate, they are left behind, and as the vapor rises; it cools and condenses into liquid form. The resulting water will be pure without fluoride.

  • Although part of distillation is boiling, note that distillation is much more efficient at removing fluoride than boiling water. (for more, read Does Boiling Water Remove Fluoride ) ; With simple boiling, the mineral is not affected as water boils. Because fluoride has a boiling point significantly higher than that of water, it remains in the container. This means that when the steam turns back into liquid again upon cooling, you now have fluoride-free water.

Treating Fluoride in Water Pipes

If you wonder how to remove fluoride from water pipes, you can employ activated carbon filters. Their porous composition and adsorption properties make it possible to hold even more fluoride. Activated carbon granules act in the water pipes as a capture point for fluoride ions, impurities, and contaminants through flowing waters within these activated carbons that have surfaces with various pores utilized for attracting and retaining fluoride, impurities, and contaminants. 

As the water passes over the filter, fluoride ions bind with the carbon, thus lowering the fluoride levels. Renowned for the ability to target and trap a wide variety of contaminants, carbon filters are usually the most favored solution among households and other businesses looking to filter out their water impurities.

How Effective Are These Methods for Fluoride Removal at Home?

While all the solutions mentioned above (distillation, reverse osmosis, activated carbon) are effective at filtering out fluoride, let’s analyze each method in terms of efficiency, cost, and convenience.

Reverse Osmosis

Reverse osmosis has a long term of between 10-15 years. Filters, however, do require replacement periodically, normally once annually. Though reverse osmosis filters are pricey at first, they are economical in the long run. 

Distillation 

Distillation is much more inexpensive compared to this since it does not contain filters and requires regular maintenance. However, distillation is an extremely slow process. It may take an at-home distiller up to 5 hours to produce a single gallon of purified water, which makes this option viable only for couples or individuals.

Activated carbon filter

Activated carbon filters are also affordable and convenient and work best to get rid of fluoride from water pipes.
