The Best Filters To Remove Fluoride From Water

The Best Filters For Removing Fluoride From Water

In A Nutshell

The best way to remove fluoride from tap water is to use a filter containing Brimac (or bone char) —  these filters will consistently remove 90% of fluoride from water. Another good option is use a Propur drip filter — these filters make use of AquaMetix a new proprietary carbon-based filtration technology — these filters will remove 50% – 85% of fluoride.

The Details

Fluoride is difficult to remove from water. Filters by Brita and Pur use activated carbon, which does not remove any fluoride. The filtration methods listed below are only methods recommended by the EPA (United States Environmental Protection Agency) and the WQA (Water Quality Association) for fluoride filtration.

You also absorb fluoride when showering and bathing. Unfortunately, there are no shower filters that will remove fluoride. But you can get a “whole house” filter for fluoride. A good vendor for “whole house” filters is FilterWater.Com. Another option is to capture rainwater and use it instead of municipal water — see the book Rainwater Collection For the Mechanically Challenged for more information.

Why Remove Fluoride From Your Water?

Fluoride has long been known to be a very toxic substance. This is why, like arsenic, fluoride has been used in pesticides and rodenticides (to kill rats, insects, etc). It is also why the Food and Drug Administration (FDA) now requires that all fluoride toothpaste sold in the U.S. carry a poison warning that instructs users to contact the poison control center if they swallow more than used for brushing.

Excessive fluoride exposure is well known to cause a painful bone disease (skeletal fluorosis), as well as a discoloration of the teeth known as dental fluorosis. Excessive fluoride exposure has also been linked to a range of other chronic ailments including arthritis, bone fragility, dental fluorosis, glucose intolerance, gastrointestinal distress, thyroid disease, and possibly cardiovascular disease and certain types of cancer.

Water fluoridation is becoming increasing unpopular around the world, due to health concerns about overexposure to fluoride. Since 2010, over 70 communities have rejected the practice, including cities like Calgary, Alberta (pop. 1.3 million people) and Albuquerque, New Mexico (pop. 500,000) that have voted to end their longstanding fluoridation programs. Most recently, the Supreme Court of Israel ruled that Israel must stop adding fluoride into public water supplies in one year, following a a decision on fluoride’s potential toxicity to humans by the Israeli health minister. Most developed nations in the world have rejected fluoridation, including 97% of western Europe. The United States, which fluoridates more than 70% of its water supplies, is an exception to this rule. According to the British Fluoridation Society, there are more people drinking artificially fluoridated water in the United States than all other countries combined.

A Closer Look At The Filter Types

Bone Char Carbon Filters

Bone Char has been used for centuries to remove naturally occurring fluoride from water. Bone contains a porous matrix that is rich in surface ions. These can be readily replaced by fluoride and by some of the other contaminants that may be present with fluoride (heavy metals). When used alone, Bone Char Carbon filters can remove up to 90% of the fluoride in water. The efficiency of bone char can be improved by adding pre-filters to remove heavy metals and other contaminants before exposure to the bone char. These filters work best at a slightly acidic pH and may not work as well with hard water.

Brimac Filters

Brimac Filter For Fluoride Removal

Brimac is a high calcium bone char. To create, you take bovine (cow) out of cold storage. The bones are thoroughly cleaned and put in sun and rain for at least 90 days and totally dried. It is then carbonized at 1472 degrees Fahrenheit in controlled conditions. The result is Kosher Certified, 100% organic bone char made of 80% phosphate of calcium, 10% carbon and 10% calcium carbonate. It lasts a long time, is non-toxic and leaves behind beneficial minerals.  There is no pH effect and it can remove chlorine, heavy metals and radioactive isotopes on top of fluoride. Bone char is considered a more effective contaminate remover than coconut because it is hundreds of times more porous and contains calcium which attract the fluoride.

Activated Alumina Filters


There are many point-of-use filters that claim to remove fluoride using activated alumina. Activated alumina is aluminum oxide, the same chemical substance as sapphire and rubies, but without the impurities that give the gems their color.

When used properly, these filters can remove up to 98% of the fluoride in water while also removing arsenic. The problem with most of these systems is that they only work for a short period of time (usually far less than claimed) before they become saturated. The other difficulty is that point-of-use systems flow too quickly to allow adequate time for adsorption. When the flow rate is faster than ¼ gallon/minute, there is not enough time to adsorb all the fluoride in the water. Recent testing of a variety of these filters revealed that few functioned as claimed for more than a few weeks.

If you are willing to work with these limitations, this filtration system may work for you.

My recommended activated alumina filter is the Tap Master Jr F2 Counter Top Filter, which costs about $90.


Countertop Water Distiller For Removing Fluoride

Distillation is capable of removing just about anything (except volatile compounds) from water. If you have a distiller, you can remove fluoride. However, distillation takes time and lost of electricity. Distillation makes water taste empty and lifeless. If you use distilled water you need to add minerals back into the water.

My recommended distiller: the Megahome Distiller, which costs about $200.

Reverse Osmosis Filters

Reverse Osmosis Filter For Fluoride Removal

Reverse osmosis relies on pressure and a semi-permeable membrane to remove contaminants from water. It can remove between 90 and 95% of fluoride (depending on the efficiency of the system and depending on how well the system is maintained). Contaminants are trapped by the membrane and flushed away in the waste water. The process requires between 2 and 4 gallons of water to produce 1 gallon of clean water. Water with an abundance of contaminants (including hard water) can reduce the efficiency of an Reverse Osmosis system and it can shorten the life of the membrane.

Like distillation, reverse osmosis removes almost everything from water, and makes the water taste flat and empty.

My recommended activated alumina filter is the iSpring 75GPD 5-Stage Filter, which costs about $170, plus any installation costs.

    Without out fluoride our teeth will turn to mush.Then after that we’ll get endocarditis (bacterial infection most commonly caused by soft teeth) and die! Also have you ever seen the teeth of someone that comes from a country that doesn’t have fluorinated water (China) and been like “Hey I want to get on board with this!” This is more bullshit from the left trying to convince the world that we are poisoning ourselves with everything. Fluoride in normal moderation is fine. You might want to be more concerned with the amount of water that you in take (8 glasses a day) in since that for sure has been linked to increased rates of kidney failure. Finally, since the hippies like NATURAL remedies shouldn’t I mention that fluoride is natural? or does it come from the land of lollipops and unicorns. While your at it do the world a favor and don’t vaccinate your kids.

      Well, that was quite an anti-hippie rant. These are the facts however:

      — Most developed nations in the world have rejected fluoridation, including 97% of western Europe
      — There are more people drinking fluoridated water in the United States than the rest of the world combined

      Brad —

      I could take the high road and answer your awful post with reason and class. Instead I am just going to state that your an absolute idiot and have no idea what your talking about. So, it is my pleasure to know that you keep gulping down your lovely tap water. Kudos you jack ass……. Drink up! Keep those four teeth you have left flourinated.

      Master —

      Your work is incredible. You do intense research and it is greatly appreciated. Keep advising the upper elevated of humanity. Rock on :)

    • jamiemadi says

      WOW, how uninformed you are ! And I will continue to be a ‘hippy’…happily! At the same time, I refuse to be a Sheople….like Brad.

      Brad, FYI…the FLUORIDE in our drinking water is FAR from natural….read up, sweet pea and keep thinking that you are getting pure fluoride in your water….how hysterical!:

      “About 90 percent of the fluoride added to public water supplies comes from silicofluorides, chemicals produced mainly as byproducts from the manufacture of phosphate fertilizers, according to the CDC.”

      Chemicals, Brad…..and don’t you think that other nasty chemicals are added with the fluoride too?? We are taking chemicals that come from factories and plants….NOT good for the human body I would not think, but then again clearly HIPPIES are a hell of a lot smarter than you ever will be!

    Yep. Even (Scientific American)[] knows something is fishy with the fluoridation of our tap water. Unfortunately, I think most of the smarter Americans have gotten used to defending science against quackery and as a result always defend anything scientific. Seems that few people in the latter group take the time to consider a) our understanding needs to be continuously re-evaluated or b) science has been and will continue to be leveraged politically. Anyways, as Americans we rarely agree on things, and there’s still lots of internet out there, so we’ll continue to drink whatever water they use at Starbucks.

  3. Dave says

    Fluoride works topically killing the mouth’s bacteria.Swallowed fluoride is mainly ineffective. A small amount gets incorporated into the tooth enamel and can cause dental fluorosis depending on how long you’ve been exposed to fluoride. The protective effect is over by age 8. After that we are swallowing fluoride with no benefit and just getting chronically poisoned. We save one filling over a lifetime! Fluoride accumulates in our bones and can make them brittle. Also we can get hypothyroid. There is increasing evidence of bone cancer(osteosarcoma) and also brain poisoning(neurotoxicity) .Could this be the cause of increasing ADHD? Don’t prepare infant formula with fluoridated tap water!!

    “When the flow rate is faster than ¼ gallon/minute, there is not enough time to adsorb all the fluoride in the water. ” This happened to me when I bought a fluoride water filter. The diverter was the wrong type.

    Why do I have to pop a sedative when I read this?
    I have to ask, “WHY?? do they sell them this way? What possible motive do these companies have to sell something that does NOT work the way it could to remove fluoride?

  5. Tom says

    I am a dentist and Dave is correct. Ingesting fluoride is only beneficial while permanent teeth have yet to erupt. After that, topical treatments with tooth paste or rinses do the trick without the side affects swallowing it. It makes no since to have everyone drink it when only few benefit from it. And to Brad, the results on dental decay is that it is is not always prevalent in many third world countries. The main culprit is when refined sugars become prevalent in the diet rather than the absence of fluoride.
    Thanks to Justin for the research!
