Do Brita Filters Remove Fluoride?

No, Brita filters do not effectively remove fluoride from water. Brita’s filters are designed to reduce chlorine taste and odor, sediment, and some contaminants like lead and copper.

However, fluoride is not effectively filtered by Brita systems. Consider using a reverse osmosis system or another fluoride removal filter to remove fluoride from your drinking water.

What About Fluoride in Bottled Water?

Many people turn to bottled water as an alternative to tap water, but not all bottled water is fluoride-free.

Some bottled water brands contain the same amount of fluoride as tap water. Before you purchase bottled water, be sure to check the label for information about fluoride content.

According to the CDC, bottled water products may contain fluoride, depending on the source of the water. “The U.S. Food and Drug Administration (FDA) sets limits for fluoride in bottled water based on several factors, including the source of the water.

Bottled water products labeled as de-ionized, purified, demineralized, or distilled have been treated in such a way that they contain no or only trace amounts of fluoride unless they specifically list fluoride as an added ingredient.

What Is Fluoride & Why Is It In Water?

Fluoride is a naturally occurring mineral commonly found in soil, water and various foods.

It is well known for strengthening tooth enamel and preventing cavities, which is why it is often added to public drinking water supplies. This is to promote good dental health and prevent tooth decay.

Fluoride is a naturally occurring mineral that helps to strengthen tooth enamel and prevent the growth of bacteria that can cause cavities.

While fluoride has many benefits, some people are concerned about the long-term effects of consuming it through their drinking water.

Despite this, many health organizations, including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), consider fluoride to be safe when used in the right amounts.

Benefits of Fluoride in Drinking Water

  • Strengthens tooth enamel
  • Prevents cavities
  • Promotes oral health
  • Cost-effective and widely available

Despite its benefits, some people choose to remove fluoride from their drinking water due to personal beliefs or health concerns.

However, it is essential to note that the appropriate amount of fluoride in drinking water has been determined by the US Public Health Service and the World Health Organization to be safe and effective for promoting oral health.

According to a recent study, hollow-fiber membrane filters did not affect fluoride concentrations in fluoridated water, but activated-carbon filters removed some fluoride.

How Brita Filters Work

Brita filters are uniquely designed to remove impurities, contaminants, and unpleasant tastes and odors from drinking water.

The filters use activated carbon to absorb and trap these substances, making the water cleaner and more enjoyable to drink.

Did you know that the U.S. uses 2,000 single-use plastic bottles per second, most of which end up in oceans?

Brita’s mission is to help people access cleaner, great-tasting water without having to trash the planet.

Key Components

  • Activated carbon – absorbs and traps impurities
  • Ion exchange resin – removes positively charged contaminants
  • Micro-screen – filters out sediment and other particles

If you switch to a Brita system, you replace up to 1,800 single-use plastic bottles yearly.

Brita’s Effectiveness in Removing Impurities

Brita filters are designed to remove specific impurities and contaminants from drinking water, making it cleaner and more enjoyable to drink.

The filters use activated carbon and other materials to trap and remove impurities, and they are most effective in removing certain substances from water.

Impurities Brita Filters are Effective in Removing

  • Chlorine taste and odor
  • Sediment
  • Lead
  • Copper

Impurities Brita Filters are Not Effective in Removing

  • Fluoride
  • Certain pesticides and herbicides
  • Microorganisms like bacteria and viruses
  • Certain minerals and heavy metals

It’s essential to understand the limitations of Brita filters and what impurities they can remove from drinking water.

While Brita filters are a convenient and affordable option for reducing specific contaminants in water, they are not a comprehensive solution for removing all impurities.

Alternatives for Removing Fluoride from Water

For those who wish to remove fluoride from their drinking water, there are several alternatives available.

These alternatives range from water filtration systems to simple household solutions, and each has its benefits and limitations.

Water Filtration Systems for Removing Fluoride

  • Reverse Osmosis: This process uses a semipermeable membrane to remove impurities from water. Reverse osmosis systems effectively remove fluoride and other contaminants such as lead and chlorine.
  • Distillation: This process involves heating water to boiling and collecting the steam. The steam is then condensed back into the water, leaving behind impurities, including fluoride.
  • Deionization Systems: These water treatment systems remove ions, specifically salts and minerals, from water through ion exchange.
  • Activated Alumina: This is a type of ceramic material that is specifically designed to remove fluoride from water. Activated alumina filters are typically used in large-scale water treatment plants but can also be used in home filtration systems.

Household Solutions for Removing Fluoride

  • Boiling water
  • Using fluoride-removing filters or pitcher inserts
  • Using fluoride-free toothpaste and mouthwash

Research and consider the different alternatives for removing fluoride from drinking water, considering each option’s effectiveness, cost, and practicality.

Additionally, it’s important to note that some options may not effectively remove all forms of fluoride and may not remove other impurities and contaminants in water.

Hydration & Health

  • Water helps regulate body temperature
  • Water helps transport nutrients and waste products
  • Water helps lubricate joints and tissues
  • Water aids digestion and elimination

Disease Prevention

  • Water helps prevent dehydration, which can lead to serious health problems
  • Water helps prevent certain waterborne illnesses and diseases
  • Water helps prevent chronic conditions such as kidney stones and urinary tract infections

Ensure that the drinking water we consume is clean and free from impurities and contaminants. This includes using water filtration systems, boiling water, or alternative household solutions to remove impurities from drinking water.

Drinking clean water can improve health and well-being and is essential to a healthy lifestyle.

Fluoride Research Statistics

Consider these fluoride statistics according to a recent article about ingested fluoride:

  1. Fluoride is present in water sources ranging from 0.1 to 10 mg/L.
  2. Fluoride is added to water in the US in the range of 0.7-1.2 mg/L to prevent dental cavities.
  3. Fluoride can cause dental fluorosis, a cosmetic condition characterized by discoloration and mottling of the enamel at doses above 2 mg/L.
  4. Chronic exposure to high fluoride levels (above 4 mg/L) has been linked to several adverse health effects, including skeletal fluorosis and decreased bone density.
  5. Long-term exposure to high fluoride levels has also been associated with decreased IQ in children and cognitive decline in elderly populations.

Frequently Asked Questions (FAQ)


Brita filters remove impurities such as chlorine, lead, and sediment, but not fluoride.

No, all Brita filters do not remove fluoride from water.

Alternative options for removing fluoride from water include reverse osmosis filtration systems, activated alumina filtration systems, and deionization systems. It’s important to consult a professional for the best option.

My Experience & Expertise

As a dentist, I see firsthand the importance of maintaining good oral health and hygiene.

Drinking clean and pure water is crucial to maintaining oral and overall health. Fluoride, a naturally occurring element found in water, can have profound positive effects on tooth decay.

For example, patients with early cavities can regularly use fluoride to heal (remineralize) tooth decay. However, too much of anything is bad. It’s up to the individual to determine if they want to remove it from their drinking water.
