  • How to Remove Fluoride From Tap Water

    When a 1960s report showed that fluoride in water reduced cavities by 90%, communities all around the country began adding fluoride to drinking water in order to improve dental health. While the recommended levels of fluoridation sat between 0.7 mg/L and 1.2 mg/L, studies began emerging about the benefits and possible side of effects of Fluoride in drinking water and it continues to be a hot topic for debate in local communities.

    You can remove fluoride from water using reverse osmosis filtration, a process that forces water through a semi-permeable membrane under pressure, leaving contaminants behind. Reverse osmosis filtration can be found within many point of use water coolers.

    Quick Facts

    • Communities all over the U.S. began adding fluoride to their drinking water during the 1960s when a report showed that fluoride in water can reduce cavities by 90%.
    • The U.S. Department of Health and Human Services recommends the ideal fluoride level of drinking water to be no higher than 0.7 parts per million (ppm) or mg/L for communities to maintain the benefits of fluoridation and avoid risk of dental fluorosis.
    • Although the right amount of fluoride can help dental health, an excessive amount of fluoride can weaken bones and ligaments and cause nervous system problems.

    Remove Fluoride from water

    As stated by Waterlogic in their recent Water Fluoridation in the USA publication, new research by the National Health and Nutrition Examination Survey found an increase in the prevalence of dental fluorosis (white spots on teeth or pitting on the surface of a tooth), the relationship between water intake and outdoor temperature, and new fluoride sources outside of tap water (e.g. toothpaste). This research led the U.S. Department of Health and Human Services to recommend the ideal fluoride level of drinking water to be no higher than 0.7 parts per million (ppm) or mg/L for communities to maintain the benefits of fluoridation and avoid risk of dental fluorosis.

    Side effects of Fluoride in drinking water

    Although the right amount of fluoride can help dental health, an excessive amount of fluoride can do more than just cause dental fluorosis. Higher levels of fluoride can weaken bones and ligaments and cause nervous system problems. It was also reported by the Fluoridealert.org, “People with clinical signs of fluorosis can suffer significant symptoms, such as chronic joint pain and overt osteoarthritis.

    Although there is a recommended level of fluoride, higher levels can occur in places where naturally occurring fluoride is detected. Laura Pressley, Ph.D., an anti-fluoridation advocate, told Waterlogic in their publication that “because oil deposits and geology,” states, such as Texas have a “higher natural level of calcium fluoride.“

    If you suspect your state or county has a higher level of fluoride, removing it from your drinking water might be beneficial to your health.

    How to remove fluoride from drinking water

    Although some individuals are content with the current levels of fluoride in their drinking water, some aren’t and they often look for options on how to remove fluoride from tap water.

    In order to filter fluoride from water, it is recommended that a Reverse Osmosis System within a point-of-use water cooler is used. Reverse Osmosis is a process that forces water through a semi-permeable membrane under pressure that will leave contaminants behind and dispense more pure and healthy drinking water. Although most reverse osmosis systems are effective at removing fluoride as well as lead, pesticides and cysts, the semipermeable membrane within the system can grow over time as contaminants are continually pressured against it. Regular maintenance of your RO system can make sure your filtration will continue working as it should.
