Best Fluoride Water Filters
Fluoride is a natural mineral that is commonly found in both well and municipal water supplies. Tap water in the US on average contains about 0.7ppm (parts per million) of fluoride – which is under the national safety standard of 4ppm.
For those who would rather not take the chance with fluoride in their water, however, there are a variety of different filter styles from countertop gravity filters to whole-house systems that can remove it.

What to Consider When Buying a Fluoride Water Filter
Even though fluoride filters come in all styles and use several different filtration methods, they can all be functionally compared using the same criteria: amount of fluoride and other contaminants removed, filter capacity and lifespan, filtration rate, certifications, and price.
Ability to Remove Fluoride and Other Contaminants
Great fluoride water filters are going to be able to remove large percentages of fluoride even at high concentrations, but it’s unlikely that fluoride is the only potentially harmful contaminant in your water.
You can get your water tested to find out exactly what’s in it, and then find a filter that not only knocks out fluoride but also works on the other contaminants as well. The most common filtration system types you’re going to find that work on fluoride are reverse osmosis (RO), gravity filtration, and special forms of carbon.
Filter Capacity & Lifespan
This capacity refers to the number of gallons of filtered water a particular filter can produce over its life, and 100,000 gallons roughly translates to a lifespan of one year for whole-house systems.
The Water Quality Association (WQA) and the National Sanitation Foundation (NSF) are two of the main independent organizations that certify water filter products for performing in accordance to certain quality standards. If a fluoride water filter is certified, it’s an added assurance that the product’s performance will live up to its manufacturers claims.

Fluoride Water Filter Buyers Guide
Now that you know the best filter of each type for fluoride, this guide will help you decide which one is going to work best for your home.
What is Fluoride?
Fluorine is the 13th most abundant element on Earth at 0.054%, which is even more than carbon. In its elemental state fluorine is a noxious yellow-green gas, but it’s most commonly found in its ionic form – fluoride, which combines with other elements like sodium.
How Does Fluoride Get in Drinking Water?
Fluoride is found naturally in the air, soil, plants, and groundwater, though it’s even more prevalent in saltwater. While fluoride can certainly be present in your water supply from its source, it’s also commonly added in trace amounts (less than 1ppm) to municipal water supplies in a process called fluoridation. This is to help ensure that people receive enough fluoride daily to promote tooth health.
Fluoride Health Effects
Fluoride is slightly controversial because it has been associated with both positive and detrimental health effects. For example, there was a 68% decrease in the average number of missing or decaying teeth in 12-year-olds after fluoridated water was introduced in the US between the 1960s and the 1990s.
This is because fluoride in small amounts helps rebuild weakened tooth enamel, prevent the loss of minerals from tooth enamel, reverses early tooth decay signs, and prevents harmful oral bacteria growth.
On the flip side, too much fluoride can cause both dental and skeletal fluorosis. Dental fluorosis causes harmless white spots to appear in tooth enamel when mild, but pitting of the enamel and damage when severe. Skeletal fluorosis can cause joint pain and stiffness, and eventually progress to the calcification of ligaments with prolonged exposure to very high fluoride doses.
While fluorosis is most commonly caused by swallowing toothpaste or exposure to excessively high fluoride in the water (over 2ppm) over a long period of time, many people would rather not chance having any in their water – which is where water filtration comes in.
Types of Water Filters That Remove Fluoride
There are many different types of filters that remove fluoride in today’s marketplace. It doesn’t matter if you’re looking for a 5-stage whole house filter that installs at the main water line or a point-of-use filter that sits on your countertop.
Here’s a breakdown of the types of filters you can find that can work on fluoride:
- Under-sink filters
- Whole house water filters
- Countertop water distiller
- Countertop gravity filters
- Pitcher filters
Having said that, it’s not the filter type so much as the filtration method that makes a particular system good at removing fluoride. For example – as mentioned, regular activated carbon doesn’t work on fluoride. So if you have one under-sink filter that uses regular granulated activated carbon and one under-sink filter that uses bone char, the one with bone char is going to do better at removing fluoride every time.
These are the main filtration methods that work to remove fluoride:
- Reverse osmosis
- Bone char and other ion exchange media
- Activated alumina
How They Work
Reverse osmosis uses pressure to force water across a semi-permeable membrane that has pores large enough for water molecules but not other contaminants – including fluoride. This method of filtration is commonly used for point-of-use systems like under-sink filters, but they tend to be very inefficient when scaled up to a whole-house filter so it’s less common to find them in that form.
Bone char works to remove fluoride by acting as an ion exchange media. Fluoride ions in the water are swapped out for calcium ions in the bone char, which effectively removes the fluoride from the water supply.
Activated alumina, on the other hand, removes fluoride by adsorption. The fluoride ions become trapped on the surface of the activated alumina, and it also works on arsenic and selenium.
While some manufacturers like Pelican use bone char exclusively to remove fluoride, you’ll often see products that use a “proprietary blend” of media. This means that the manufacturer uses a multifaceted filtration system using a combination of materials they have tested and developed, but doesn’t fall strictly into any one category.
For example, you can have a proprietary blend that incorporates both bone char and activated alumina, or it can be an entirely different substance that works via ion exchange, adsorption, etc. to remove fluoride.
What to Look for When Buying a
Fluoride Water Filter
Municipal vs Well Water Supply
If you’re on municipal water, odds are that you have fluoridated water. With well water, the fluoride concentrations are likely to be much more variable depending on where you live and you’re also likely to have a different subset of other contaminants.
Getting your water tested will let you know what contaminants are present in what amounts in your water, which will help you pick a filter that works on both fluoride and the other impurities. You can see our review of the best water testing kits here.
Ease of Installation and Use
If you’re looking at filters that require installation like whole-house systems or under-sink filters, you’ll want to check ahead of time if they’re going to need a plumber to install. Not only is this an added expense, but trying to DIY it can actually void the manufacturer’s warranty in some cases.
Likewise, if using the water filter isn’t simple, then it might not be worth your money. If one of the filter stages needs to be changed out every 6 months but it’s a pain to do, it’s going to cause you a lot of frustration and headaches down the line. You may even decide to push changing it out an extra month or two, which can affect your water quality.
Your Home’s Filtering Needs
If you’re living in an apartment or dorm room, your filtering needs are going to be significantly different than those with large households in standalone homes.
For example, if you’re single and living in a small home, you might find that systems that filter 100 gallons per day are sufficient. For those living in busy homes that use a lot more water, however, you might need to find filters and systems with much higher capacities.
Whether you need something as simple as a water pitcher filter or something as large-scale as a whole house filter is also going to vary from home to home. For homes on well water, you’re pretty much going to need a whole-house system no matter what.
For those with a municipal supply, it may depend on the other contaminants in your water besides fluoride for whether you want just your drinking water to be filtered or the water you wash clothes with, shower in, etc to be filtered as well.
What Other Customers Have to Say
As with anything, make sure you read through the customer reviews for each fluoride water filter. In doing so, you’ll learn more about replacement filters, contaminant reduction, if they’re easy to use, the water quality they produce, if the filters are long lasting, etc. You’ll also learn what some of the most common concerns and pain points are for each filter, which may factor into your overall decision.
Fluoride Filter FAQs
These are some of the most common questions other customers have had when looking to purchase a fluoride water filter:
Q: How do I know a filter removes fluoride?
A: Many manufacturers publish the percentage of fluoride that their filter removes from water based on in-house and independent testing. If you want to be completely sure that a filter works as advertised, look for ones that have been certified by the NSF, WQA, or other independent organization.
Q: Are there fluoride shower filters?
A: There are not currently fluoride filters that are specifically made for shower heads. Having said that, if you get a whole-house filter that removes fluoride then the water that goes to your shower after will have already been filtered for fluoride.
Q: Is it dangerous to drink fluoride?
A: It all depends on the levels in your water. At less than 1ppm, fluoride has been shown to have positive effects on tooth enamel. When consumed at more than 2ppm for a long period of time, however, it can lead to a disease known as fluorosis.
Q: What types of filters remove fluoride?
A: Many different filters can remove fluoride if they use the right filtration method. You can find fluoride filters available as whole-house systems, under-sink filters, countertop filters, or even water filter pitchers.
