If you’re one of the people who has decided you want to remove fluoride from your water you’ve come to the right place.
There is evidence to show that fluoride may play a role in numerous health issues if consumed in too large of amounts.
Considering the fact that most water treatment plants actually add fluoride to your city water supply, you’ve probably realized the only way to solve this problem is to filter fluoride out at home.
The good news is, there are a variety of different fluoride-specific filters you can use.
These range from countertop systems and sink water filters to whole-house systems.
Deciding which filter to buy to remove fluoride can be difficult – but we’ve done the hard part for you.
We’ve spent countless hours testing, researching, reviewing, and comparing fluoride filters on a specific set of criteria that they need to match in order to be effective.
You can see the best fluoride water filters in our guide below.

What to Consider When Buying a Fluoride Water Filter
Even though fluoride filters come in a variety of styles and use several different filtration methods, it’s possible to compare them using the same criteria: the amount of fluoride and other contaminants they remove, the filter capacity and lifespan, the filtration rate, certifications, and price.
Capability to Remove Fluoride & Other Contaminants
A great fluoride filtration system removes a high percentage of fluoride as well as other contaminants in your water supply since no water supply contains only one type of contaminant.
By testing your water, you can find out exactly what harmful chemicals and contaminants it contains. Then, you can find a filter that will remove fluoride from water along with all those additional contaminants.
The most common water filtration systems that are effective for fluoride removal use reverse osmosis (RO), gravity, or special forms of carbon.
Filter Capacity & Lifespan
A fluoride filtration system with long-lasting filters will require less maintenance and ultimately cost less over the long term. It’s important to note that whereas some manufacturers publish the lifespan of their filters in years, others show the capacity rating in gallons.
Capacity refers to the number of gallons of water a filter can process. For instance, 100,000 gallons is approximately a lifespan of one year for a whole-house fluoride water filter.
Flow rate describes the water pressure of filtered tap water, usually in gallons per minute (GPM). It’s important to find a water filter that’s effective at removing contaminants without decreasing flow too much.
The two main independent organizations that certify water filtration products in accordance with defined quality standards are the Water Quality Association (WQA) and the National Sanitation Foundation (NSF). Certification from either of these organizations increases the likelihood that a fluoride filtration system will meet its manufacturer’s claims.
Price is always a key consideration when comparing the best water filters. We have made sure that each of the models on our list offers great value for money.
In addition to the price of the filtration system itself, it’s necessary to consider future costs, such as for replacement filters.

Fluoride Water Filter Buyers Guide
What is Fluoride?
At 0.054 percent, fluorine is the thirteenth most abundant element on Earth, ranking even higher than carbon.
In its elemental state, fluorine is a noxious yellow–green gas, but it’s most commonly found in its ionic form: fluoride. This form combines with other elements like sodium to create substances such as sodium fluoride.
How Does Fluoride Enter Drinking Water?
Fluoride occurs naturally in the air, soil, plants, and groundwater, although it is most prevalent in saltwater.
Whereas fluoride can certainly be present in your water supply naturally, it is commonly added in trace amounts (less than 1 ppm) 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 negative health effects. For example, there was a 68 percent decrease in the average number of missing or decaying teeth in 12-year-olds after fluoridated water was introduced in the U.S. between the 1960s and the 1990s.
This is because fluoride in small amounts can rebuild weakened tooth enamel, prevent tooth enamel from losing minerals, reduce tooth decay (or even reverse tooth decay that already exists), and prevent harmful oral bacteria growth.
On the flip side, too much fluoride can cause dental and skeletal fluorosis. Mild dental fluorosis just leads to white spots on tooth enamel, but severe dental fluorosis causes pits and other damage in the enamel. Skeletal fluorosis causes joint pain and stiffness and, in the case of prolonged exposure to very high doses of fluoride, can eventually progress to the calcification of ligaments.
Although fluorosis is most commonly caused by swallowing toothpaste (which you can prevent by using fluoride-free toothpaste) or exposure to excessively high amounts of fluoride in the water (over 2 ppm) over a long period of time, many people would rather not take any risks. This is where water filtration to reduce fluoride exposure can help.
Types of Water Filters That Remove Fluoride
There are several types of filtration systems that remove fluoride from water. These range from five-stage whole house filters that you install on your existing water line to point-of-use filters that you either attach to your kitchen sink faucet or that sit on your countertop.
Fluoride reduction filtration systems fall into five main categories:
- Under-sink filters
- Whole-house water filters
- Countertop water distiller
- Countertop gravity filters
- Pitcher filters
When considering the effectiveness of a filter, though, the filtration method is more important than the filter type. For example, a regular activated carbon filter is ineffective for fluoride reduction. This means that if you compare an under-sink filter that uses a regular granulated activated carbon filter and one that uses bone char, the one with bone char will remove fluoride to a much greater extent.
The main filtration methods that are effective for fluoride reduction are:
- Reverse osmosis
- Bone char and other ion exchange media
- Activated alumina
How The Filter Types Work to Remove Fluoride
Reverse osmosis systems use pressure to force water across a semipermeable membrane. The reverse osmosis filters have pores that are large enough for water molecules to pass through, but other contaminants – including fluoride – are trapped by the filter. This method of filtration is common in point-of-use systems like under-sink filters, but it is too inefficient for a whole-house filter.
Bone char acts as an ion-exchange filter medium to remove fluoride from water. It does this by swapping fluoride ions in your drinking water for the calcium ions in the bone char.
Activated alumina removes fluoride by adsorption. The fluoride ions are trapped on the surface of the activated alumina. This method is also effective at removing arsenic and selenium from unfiltered water.
Whereas some manufacturers like Pelican use bone char exclusively to remove fluoride from drinking water, you’ll often see products that use a “proprietary blend” of media.
This means that the manufacturer uses a multifaceted filtration system that uses a combination of materials the manufacturer has tested and developed. These proprietary blends don’t fall strictly into any one category.
For example, a proprietary blend may incorporate both bone char and activated alumina or it may be a substance that uses ion exchange, adsorption, or another filtration process to remove fluoride from drinking water.
What to Look for When Buying a
Water Filter for Fluoride Reduction
When assessing water filters, we took five main criteria into account: the amount of fluoride and other contaminants they remove, filter life, flow rate, certifications, and price.
Whereas this gives you a good baseline to compare the quality of different filters, there are other factors that will help you determine if a particular system is a good fit for your home.
Municipal vs Well Water Supply
If you receive municipal water, the likelihood is your drinking water is fluoridated.
However, fluoride concentrations are much more variable in well water. You’re also likely to have a different subset of contaminants.
Receiving a water test will show you what contaminants are present in your drinking water and in what amounts. This will help you pick a filter that is effective for filtering water both of fluoride and of the other impurities.
Find a water testing kit that meets your needs by checking our review of the best kits.
Ease of Installation and Use
If you’re looking at filters that require installation, such as whole-house filtration systems or under-sink filters, you should check in advance if it is easy to install. If a plumber will need to install the filtration system, this will add an extra expense. Bear in mind that installing a filtration system yourself may void the manufacturer’s warranty.
Similarly, consider how easy it is to maintain the filtration system. Some systems require you to change the filter cartridges as often as every six months. If switching the cartridge is difficult, you may prefer to choose a different system. Keeping a filter cartridge in longer than recommended will diminish your water quality.
Your Home’s Filtering Needs
If you’re living in an apartment or dorm room, your filtering needs are significantly different than those in large households with a high water usage. For example, if you’re single and living in a small home, you may find that 100 gallons per day is sufficient. In a larger household, however, you may need a filter with a much higher capacity.
There are also major differences between water pitcher filters and large-scale whole-house systems. If you receive well water, a whole-house system is likely necessary for filtering contaminants other than fluoride. Those with a municipal water supply, however, have more choice. What you choose will depend on the contaminants in your water besides fluoride and whether you just want to filter your drinking water or you also want purified water to wash clothes, wash the dishes, and for showers.
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 their filter removes based on their own and independent testing. To be completely sure a filter works as advertised, look for systems that have been certified by the NSF, WQA, or other independent organizations.
Q: Are there fluoride shower filters?
A: There are not currently any fluoride filters specifically for shower heads. Nonetheless, if you purchase a whole-house filtration system, it will reduce fluoride from the water that comes out of your shower.
Q: Is it dangerous to drink fluoride?
A: Fluoride toxicity depends on the levels of fluoride in your drinking water. When fluoride is less than 1 ppm, it is safe to drink water. In fact, fluoride at these levels has positive effects on tooth enamel. However, drinking water with more than 2 ppm of fluoride for an extended period of time can cause fluorosis.
Q: What types of filters remove fluoride?
A: Many types of filters can remove fluoride — it’s all about the filtration method. You can find fluoride filters as whole-house systems, under-sink filters, countertop filters, and even water filter pitchers.
Our pick for the best overall fluoride water filter is the Clearly Filtered Under Sink Unit, thanks to its fantastic filtering capabilities and high capacity.
Another good option is the Pelican Whole House filter, which is also our choice for the best point-of-entry system.
The Aquasana OPTIMH2O system is a more affordable alternative to the Clearly Filtered model.
It can be difficult to determine which fluoride water filter is the best for your home, especially since there are many options, including whole-house units, under-sink systems, pitchers, and countertop units.
Once you know your home’s filtration needs, you’ll be able to determine which type of filter will be a good fit.
