How to Remove Fluoride from Water?

Fluoride in Drinking Water: The Fluoride Controversy

Why is fluoride added to drinking water? For more than 70 years, fluoride has been added to America’s public water supply. Fluoridation began after scientists found that people had fewer cavities, if they lived in an area where fluoride was naturally more prevalent in the water.

Today, the American Dental Association (ADA) continues to advocate for fluoridation, arguing that it is helpful to the American public:

"Scientific research has consistently shown that an optimal level of fluoride in community water is safe and effective in preventing tooth decay by at least 25% in both children and adults.”

What is known about fluoride in drinking water? What started out with one water supplier adding fluoride to water in the 1940s, has increased to 67 percent of homes in the U.S. now receive fluoridated water.

The U.S. Department of Health and Human services recommends the level of fluoride in drinking water be "no higher than 0.7 mg/L to reduce the risk of dental fluorosis among children."

But many are starting to wonder if the practice of fluoridating the public water supply is not such a good idea. 

Effects of Fluoride in Water

Dozens of organizations are currently campaigning for the discontinuance of fluoride additive, asserting that:

  • Once added to the water supply, there is no way of controlling the dose of fluoride; it goes to everyone regardless of weight, health, age, and need.
  • Fluoride is known to have toxic properties at low doses.
  • Many children already exceed the daily fluoride intake recommendations from toothpaste alone.
  • Fluoride accumulation may make bones brittle and prone to fracture.
  • Fluoride may be hurting the environment since 99% of our water supply is not used for drinking but is flushed down the drain.
  • A study in England suggests that water fluoridation may increase the risk of developing hypothyroidism, or under active thyroid. 

How to Remove Fluoride from Drinking Water

Because many children exceed their daily fluoride intake recommendations (from toothpaste alone), some households are now using water filters to remove fluoride from household drinking water. 

Why Remove Fluoride from WaterCan a Water Filter Remove Fluoride?

A reverse osmosis filtration system is a simple solution for removing fluoride from drinking water. A Reverse Osmosis (RO) system can remove 85-92%* of fluoride in your water.

Essentially, reverse osmosis technology uses household water pressure to push tap water through the filtration process. The water passes through a semipermeable membrane, as well as additional filters such as sediment or carbon filters (many RO units incorporate a 4-stage process for optimal water quality). You can learn more about how reverse osmosis works here.

What Filter Systems Remove Fluoride from Water?

Reverse osmosis filters out fluoride and many other contaminants including: 

Are Water Filters that Remove Fluoride Expensive?

Reverse osmosis has become increasingly popular because it is a safe, cost-effective, easy-to-maintain water filtration system. A family of four can have fresh, great-tasting RO-filtered water each day for just pennies per gallon. A new reverse osmosis system typically costs less than $300.

The footprint of a residential RO system is small and is typically installed under a kitchen sink. The system can also be connected to your refrigerator and ice machine.

A whole-house reverse osmosis system allows you to have filtered water at all sinks throughout the house and is generally installed in the garage of a home. But this type of system is often considered to be cost prohibitive for most homeowners due to high ongoing maintenance costs and pre-filtration requirements before water enters the RO system.

Instead, for fluoride removal, we recommend a small reverse osmosis water filter system installed for drinking water at the kitchen sink. You might also consider installing a UV light water purifier to protect all the water coming into your home from microbiological contaminants such as viruses and bacteria. offers top-quality systems at affordable prices.
