Why is Fluoride in 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 in preventing tooth decay and creating stronger teeth.

In the U.S., 67% of homes receive water that has been fluoridated.

Effects of Fluoride in Water

No Dose Control
Once added to the water supply, there is no way to control the dose of fluoride--same does to everyone regardless of weight, health, age, and need.

Too Much Already
Many children already exceed the daily fluoride intake recommendations from toothpaste alone.

Environmental Impact
Fluoride may be hurting the environment since 99% of our water supply is not used for drinking but is flushed down the drain.

Teeth Staining
Fluoride can cause teeth stains or patches of white and yellow known as dental fluorosis.

Brittle Bones
Fluoride accumulation may make bones brittle and prone to fracture.

Thyroid Impact
Fluoride may impact thyroid function for some individuals. One study shows water fluoridation increases risk of hypothyroidism.

Toxic Properties
Fluoride is known to have toxic properties even at low doses.

How Do Reverse Osmosis Filters Remove Fluoride?

A reverse osmosis filtration system is a simple solution to get fluoride out of drinking water.

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). Learn more about how reverse osmosis works.

RO systems are installed as under-sink or countertop filters to provide clean drinking water at the kitchen tap.

RO filtration not only improves the taste, smell and appearance of drinking water, but also effectively reduces PFOS, fluoride, chlorine, pesticides, lead, and dozens of other contaminants.
