The problem with water fluoridation is that, once added to our water supplies, there’s no way of controlling who ingests how much fluoride. This can be a serious problem especially for the majority of kids that already exceed the recommendation for daily fluoride intake by nutrition alone.
As a growing part of the population wants to opt out of water fluoridation, the demand for filter systems that can remove fluoride from water increases.
If you too are serious about going fluoride-free check our buying guide below. It features the best water filters to remove fluoride among other helpful stuff.

Pros
- The only water filter pitcher tested against 5 NSF standards (42, 53, 244, 401, P473) with outstanding results. Targets far more than 365 water contaminants including fluoride, chlorine (99.5%) and chloramine (99.7%), bacteria and cyst (99.99%), lead (99.3%), arsenic (98.3%), chromium-6 (97.8%), two dozen pharmaceutical drugs (up to 99.9%), a bunch of herbicides (up to 99.9%), pesticides (up to 99.8%), PFAS (99.0-99.5%), and more than 100 VOCs (most to 99.9%).
- Healthy minerals are kept in the drinking water adding to your daily nutritional intake.
- Uses Affinity Filtration Technology, a combination of granular activated carbon and several other proprietary filter materials.
- Pitcher is super easy to assemble – barely takes 2 minutes – and use (we tested this ourselves).
- Holds up to 10 cups of water which is enough for a whole family if you remember to refill on a regular basis.
- Pitcher + filters are made in the USA from medical-grade Tritan plastic. 100% BPA-free.
- One cartridge has a filter life of 100 gallons of water or 4 months on average. Keeps maintenance at a bare minimum. Cost per piece: $50 (cheaper if you buy in bulk and subscribe).
- Full refund thanks to 30-day money-back guarantee if you’re not satisfied.
- Lifetime guarantee on pitcher and A+ customer support.
Cons
- The Clearly Filtered water filter pitcher is more costly to purchase and maintain than most of the competition.
- A few people have reported that their filters don’t last as long as advertised and that the filtration speed is rather slow. Personally we haven’t had any issues.
- A long contact time between water and filter media can be a good thing. It allows for a more thorough filtration.
- Clearly Filtered replaces defective water filters free of charge.
Best for
The Clearly Filtered is best for people who want a fluoride water filter pitcher that’s easy to use, extremely effective, and affordable.

2. Best for Reverse Osmosis Fluoride Removal: AquaTru
A study conducted by the University of Nebraska in 2008 showed that even small point-of-use reverse osmosis systems are very well capable of removing fluoride from tap water – some systems are certified to take out more than 90%.
In our opinion, the number one reverse osmosis fluoride water filtration system in 2022 is the AquaTru. Certifications according to NSF standards 42, 53, 58, and 401, and NSF protocol P473 guarantee the removal of dozens of hazardous contaminants that you don’t want in your drinking water (fluoride reduction rate: 93.5%).
The highlight, however, is that the AquaTru countertop RO system doesn’t require a permanent installation. You just place it on your countertop, plug in the power cable, and you’re good to go – it’s super convenient and ideal for renters. The cherry on top is that maintenance couldn’t be easier and the system is affordable, as well. 4.5 stars!

Pros
- The AquaTru countertop reverse osmosis system has earned 5 NSF certifications which guarantees clean, healthy, and great-tasting water for drinking and cooking with more than 80 contaminants removed, including fluoride (93.5%), lead (99.1%), chromium-6 (97.2%), PFAS (97.5%), pesticides, drug residues, organic compounds, chlorine, and cyst (99.99%).
- Uses 4-stage filtration process to achieve these results.
- Stage one and two is a combination of sediment and activated carbon pre-filter. Apart from chemicals and bad taste and odor, it filters larger particulates to protect the rest of the system from clogging.
- The reverse osmosis membrane rejects the contaminants listed above + others.
- Stage four uses a carbon filter block for final polishing.
- Fast filtration purifies one gallon of water in 10-15 minutes thanks to built-in water pressure pump.
- High water pressure also reduces wastewater production. The recovery rate is 80%, meaning only 20% of the input water goes down the drain (reverse osmosis water systems that don’t feature pumps waste around 3-5 gallons for every gallon of filtered water).
- System setup doesn’t involve drilling or plumbing and barely takes 10 minutes.
- Design is space-saving.
- Operation is intuitive: Fill water into the removable tank and install it back into system. The RO water collects in the front storage tank (can be removed for cooling). Reject water collects in second tank ready to be discarded.
- Easy push button dispensing.
- Plastic material is BPA and BPS-free.
- The different filters will last between 6 months and 2 years. Annual/biannual replacement only takes a few minutes with no need for tools. Lights on the front panel will tell you whenever it’s time for a new filter.
- Cost: We estimate between $100 and $120 a year which is really affordably.
- Manufacturer warranty is one year.
Cons
- A few people had issues with leaks. For others, the filtration system stopped working entirely.
Best for
The AquaTru is best for people who want a reverse osmosis system for fluoride removal, one that is compact, installation-free, super effective, and fast.

3. Best for Under Your Sink: Clearly Filtered 3-Stage System
Our go-to under sink fluoride water filter in 2022 is the Clearly Filtered 3-Stage system. Apart from removing 90.7% sodium fluoride, it takes care of 230+ other water contaminants. And this is not just a claim. It has been tested by independent EPA-approved laboratories according to NSF standards.
Simply put, you won’t find an under sink water filtration system that outperforms the Clearly Filtered 3-Stage in terms of overall contaminant removal. 5 stars!

Pros
- The under sink water filtration system is NSF standard 42, 53 and 401 tested to capture chlorine (98.6%), chloramines (95.3%), arsenic (94.3%), hexavalent chromium (99.4%), lead (98.9%), PFAS (up to 99.8%), more than a hundred VOCs and SVOCs (up to 99.9%), and many other types of contaminants found in water. The result is healthy and clean drinking water.
- Maintains all healthy minerals.
- Uses 3 filter stages. Stage 1 is coconut shell granular activated carbon. Stage 2 and 3 are proprietary media blends (Affinity Filtration Technology).
- DIY installation doesn’t take more than 15 minutes and is non-permanent. Great for renters and to save money.
- Mounting the system under kitchen sink is optional. All hardware is included.
- Filters last a full year on average and can be replaced in seconds – tools-free and without the need to shut off the feed water supply.
- Made in USA.
- Uses stainless steel hoses for durability.
- Whole under sink system is covered by lifetime warranty.
- You have a 30-day window after purchase to return the product if you’re not satisfied and receive a full refund.
Cons
- System reduces water pressure by about 15-25%.
- Considerably more pricey than competitor water filters. This also applies to the replacement filters.
- Worth the investment if you ask us.
- Subscribe to receive filters automatically on schedule and save 10% + get free shipping.
Best for
The Clearly Filtered 3-Stage is best for people who want an under sink fluoride filter that’s compact, easy to install and use, and very effective.

4. Best for Whole House: Crystal Quest Fluoride Filter
For whole house applications, the best fluoride water filter in 2022 is the Crystal Quest. Fluoride reduction: 90-95% when used as intended. The high quality system comes in 2 different sizes. The smaller version is for homes with up to 3 bathrooms. The larger system is for 4+ bathrooms.
Both come with a programmable head valve which allows for automatic backwashing to increase the life of the fluoride filter media to as much as 1 million gallons! In other words, you don’t have to worry about replacing the media for several years. The long filter life is also what makes the Crystal Quest fluoride whole home water system a worthwhile investment. The initial price tag seems high but it’s all the more affordable in the long run, especially compared to cartridge-based systems. 4.5 stars.

Pros
- Uses mineral tank filled with granular activated charcoal-based fluoride filter media (bone char).
- Mixture of adsorption and chemical reaction to remove as much fluoride as possible.
- Also effectively removes lead, mercury, and arsenic.
- Copper-zinc alloy additive prevents bacteria growth inside the mineral tank.
- 5-micron sediment pre-filter (20”) traps silt, sand, dirt, and other large particles so they don’t get stuck in the mineral tank.
- 5-micron coconut-shell carbon block post-filter (20”) removes any chemicals and other contaminants to improve drinking water taste.
- 1.5 cubic feet filter media (small version) lasts 750,000 gallons at 9-11 gallons of water per minute flow rate. 2.0 cubic feet media (large version) lasts 1,000,000 gallons at 10-13 gpm flow rate.
- Maintenance-free for up to 10 years.
- System designed for municipal water containing inorganic fluoride.
- Can be used over a wide water pH range.
- Choose between fiberglass or steel casing for durability.
- Easy installation and programming thanks to solid instructions.
- Sediment pre-filter life: Up to 2 years. Carbon post-filter lasts 12-18 months. We estimate 8-10 years for a family of 4 before the bone char needs to be replaced.
- Total average annual cost: $115-140, depending on system size.
- Covered by manufacturer warranty for one year.
Cons
- Expensive at purchase.
Best for
The Crystal Quest is best for people who want a highly effective POE filter system for fluoride removal.
5. Whole Home Alternative: Crystal Quest Big Blue
For smaller homes with 1 or 2 bathrooms, the Crystal Quest Big Blue system might provide a high-enough flow rate to meet your water demand even at times of peak consumption.
The max water flow rate is 4-6 gallons per minute. So you can’t really use more than 2, maybe 3 water outlets at the same time without experiencing a drop in water pressure or unfiltered water leaching through.
As for the filtration itself, the filtering media is identical to what the larger Crystal Quest water filtration system uses: Bone char + bacteriostatic copper-zinc additive. Fluoride reduction: 90-95%.
The Crystal Quest Big Blue is a lot more affordable upfront, but it’s more costly to maintain on a yearly basis. You’ll probably have to replace the filter cartridge at least once a year. As of 12th January, 2022, one cartridge costs $239.00 which is about twice as much as you’d have to spend for the other Crystal Quest system.
6. Best for Showering: Propur ProMax
Is there even such a thing as a shower (head) water filter which removes fluoride? Unfortunately, there isn’t – at least not really. Yes, there are companies that list fluoride-reducing shower water filters, but they’re just not very effective. The best unit we could find is the ProPur ProMax. Reduction rate: Around 48.2%.
Well, better than nothing but we recommend installing a whole house fluoride water filter instead, if you have the budget. A point-of-entry system will treat all the water entering your home which, of course, also includes your shower water. Simply put, the filtration is much more thorough. For example, the Crystal Quest water filter reviewed above eliminates 90-95% fluoride.
In case you want to stick with the Propur ProMax, here’s our review:

- Chloramine (71.0%), chlorine (57.1%), sodium fluoride (48.2%), VOCs (most around 90%), arsenic (28.0%), chromium (28.8%), lead (61.1%), mercury (79.2%), pesticides (approx. 50 to 60%), semivolatile compounds (70-80%), nitrites (82.8%), nitrates (23.6%) etc.
- Results are not perfect but better compared to most other shower filters.
- 2 gallons per minute water flow rate provides for enough pressure.
- Includes massaging head with 5 spray settings.
- Choose from 3 different finishes: Chrome, antique bronze, brushed nickel.
- Brushed nickel and chrome versions are also available with a handheld wand.
- Installation and maintenance is straightforward and doesn’t take much time.
- Fits standard ½” pipe threads.
- Filters last 6 months. Cost: ~$42 a cartridge which is acceptable.
- Made from BPA-free plastic.
- 30-day money back guarantee + 1 year limited warranty.
Cons
- Relatively expensive.
Best for
The Propur ProMax is best for people looking for a fluoride shower filter that’s easy to install and maintain, long-lasting, and quite effective.

7. Best for On the Go: Clearly Filtered Bottle
In our opinion, the top fluoride filter bottle in 2022 is sold by Clearly Filtered. In fact, the company sells 3. There’s an insulated stainless steel filtered water bottle, a filter bottle made from Tritan plastic, and one made from glass.
Different materials yes, but all apply the same filter cartridge to remove more or less the same contaminants the Clearly Filtered pitcher removes (reviewed above). Thus, you can expect very thorough drinking water filtration – the most thorough in the realm of filter bottles as far as we know. Fluoride reduction rate: 99.5%. People couldn’t be happier about their purchase and would buy again. 5 stars!

8. Best for Countertop + Portable Gravity Fluoride Filtration: Big Berkey
Berkey systems are popular gravity water filters, especially in the SHTF community. As portable countertop units, they’re easy to install, easy to use, low in maintenance, and very effective at removing a whole arsenal of contaminants to provide high-quality water. Long-term fluoride reduction: 97% when used with optional PF-2 fluoride water filters.
By the way, there’s no difference between the various Berkey models except for their size which determines filtration speed and water holding capacity. Other than that, they work with the same filter elements and thus achieve the same level of water purity. Our personal favorite is the Big Berkey system. It’s perfect for small families with up 4 people but is not too bulky for most kitchens and to be moved around. 4.5 stars!

9. Best for Inline & Refrigerator Fluoride Water Treatment: Universal
In our opinion, the number one inline/fridge water filter that removes fluoride in 2022 is the Clearly Filtered Universal. It’s the only unit we could find that’s actually tested for fluoride. And it’s very effective, too, and works flawlessly. Average sodium fluoride reduction: 90.7%!
Prop tip: As an inline water filter, the Clearly Filtered Universal is compatible with all appliances including refrigerators. When you install it, you’ll no longer need to use the filter that comes with your fridge. Depending on your fridge model, you might be able to bypass it or take it out.

Buying Guide: How We Picked the Best Water Filters That Remove Fluoride
The following are things worth considering before you go out and buy a fluoride water filter. These are also the very same criteria we focused on when picking our top products for this guide.
NSF/ANSI International Certifications
Reverse osmosis systems can be tested and certified according to NSF Standard 58 for fluoride reduction. NSF International is a not-for-profit organization which develops industry standards. So when comparing different RO systems make sure to check their performance data sheets.
You might also find reduction rates for non-RO water filters which is great. Just know that any performed testing cannot be standardized because there currently doesn’t exist a standard.
The Different Types of Fluoride Water Filters
5 methods of water purification have proven to be effective at fluoride removal: Reverse osmosis, ion exchange, distillation, and treatment with activated alumina or bone char media.
So, removing fluoride from the water we use isn’t as much about the type of filter, for example under sink vs. countertop, than it is about the specific purification process applied.
Still, there’re certain filter types that appear to be more popular and effective than others when it comes to fluoride filtration. They are:
- Countertop and under sink RO systems
- Water filter pitchers
- Whole house filters
- Regular under sink water filter systems
- Gravity units
- Water distillers
- Filter bottles
Water Filters That Won’t Reduce Fluoride
We don’t know of any faucet water filtration system that removes fluoride sufficiently.
The same goes for shower filters. The most promising model is the Propur ProMax which hardly removes half of the fluoride in your water as testing has shown.
Testing for Other Contaminants in Your Water Supply
You should know your water source and the contaminants it contains. Remember: Fluoride is only one part of the equation. What if you’re also dealing with poisonous lead or carcinogenic PFOA?
Bottom line: Check your free water quality report or have your water thoroughly tested so that you can choose your ideal filtration system accordingly. Simple test kits are widely available, however, in our opinion it’s always best to go with a professional lab. These guys can test one or more direct samples of your water for hundreds of different chemicals, organics, heavy metals, etc.
Installation
Bottle, gravity, countertop, and pitcher filters as well as water distillers are installation-free which saves you quite some time and possibly money.
Under sink and whole house water filters do require proper installation. If you’re not a DIY type of guy you should calculate with a few hundred extra dollars for the install.
Filter Lifespan and Maintenance Cost
A filtration system’s initial price tag is one thing. To this you have to add recurring expenses for filter replacements.
Thus, you want to double-check how long a filter element lasts and how much a new one costs. This saves you from unpleasant surprises down the road.

Water Fluoridation – How Fluoride Gets into Our Water Supply
Fluoride or rather a fluoridated compound is deliberately added to municipal water supplies in the United States in order to reduce tooth decay – think cavity prevention. And there’s nothing wrong with that per se. After all, tap water fluoridation can reduce cavities in children.
However, efficacy in adults is less clear. This is probably why most European countries, which have experienced substantial declines in tooth decay themselves, find no benefit to water fluoridation compared with topical use in toothpaste.
This is backed by recent studies suggesting that tap water fluoridation in industrialized nations may be unnecessary due to the widely adopted use of topical fluorides.
Health Risks – How Does Fluoride Affect the Human Body?
The problem with water fluoridation is that, once added to a water supply, there’s no way of controlling who ingests how much fluoride – not a good starting point when you consider that the majority of children already exceed the daily recommended fluoride intake by nutrition alone.
What’s more, drinking water is not the only fluoride source. Fluoridated toothpaste, salt and milk, cookware, medications, and processed food also add to our daily intake. An oversupply can lead to serious health problems.
By the way, only half of the fluoride your body absorbs is stored. The rest is flushed out via urine.
Dental Fluorosis and Skeletal Fluorosis
99% of the fluoride stored in our body ends up in our teeth and bones. This is why high fluoride consumption over a whole lifetime can lead to joint stiffness and joint paint (skeletal fluorosis) as well as dental fluorosis.
Neurological Problems
The remaining 1% ends up in soft tissue such us our brain and pineal gland. Calcification of the pineal gland as a consequence of long-term fluoride oversupply can result in sleep disorders, fatigue, and depressions. (Source)
Thyroid Problems
Fluoride interferes with the functioning of the thyroid gland. It decreases the concentration of T3 and T4 thyroid hormones while increasing TSH levels. Thus, one possible result of prolonged exposure to fluoride is hypothyroidism where the entire function of the thyroid gland is suppressed.
Fluoride Intoxication
Fluoride intoxication usually only occurs under sustained consumption of large amounts of soluble fluoride salts. Historically, most cases have followed accidental ingestion of sodium fluoride based pesticides. Today, most cases of fluoride toxicity are due to the ingestion of dental fluoride products.
The lethal dose for adults is estimated at 32 to 64 mg elemental fluoride per kilogram body weight.
Best Practices to Reduce Fluoride Exposure
What can you do to reduce your overall fluoride exposure?
- Eat less processed and more organic foods – Many pesticides and insecticides used in conventional agriculture contain fluoride. Furthermore, every processing step adds the likelihood of increased fluoride concentrations in food, due to the potential use of fluoridated water and salt or fluoride being used as a preservative.
- Regulate your fluoridated salt use.
- Drink less green and black tea as well as coffee – Almost all brands of green and black tea are high in fluoride. The same goes for some species of coffee.
- Consider using fluoride-free toothpaste.
- Avoid Teflon-coated cookware – Teflon contains fluoride.
- Try to avoid medications containing fluoride – Maybe your doctor can find you a suitable alternative.
How to Remove Fluoride from Water at Home
The level of fluoride dissolved in tap water as currently recommended by the American Dental Association for optimal dental health is 0.7 ppm. The ADA further says that, even at higher concentrations, the effectively measured fluoride amount in a US water supply doesn’t exceed 1 ppm. In comparison, non-fluoridated water usually contains less than 0.3 ppm, although concentrations in groundwater can be higher.
Taking this into consideration, it’s seems fair to ask if any water filtration system is actually capable of removing or reducing such a small amount of fluoride, or if the salt simply slips through the grid of even the most rigorous filtration processes to later end up in our water glasses anyway.
To answer the question, the Water Quality Association lists four treatment methods as suited for the removal of fluoride from tap water:
- Reverse osmosis – It’s the most commonly used method of water purification and utilizes a semipermeable membrane to filter out up to 99% of all contaminants.
- Strong base anion exchange – Filtration systems based on this technology are rare. As far as we can tell, they’re only available for industrial use but not your home.
- Activated alumina adsorption media – The most popular water filters that apply activated alumina are Big Berkey systems which we’ve reviewed further above.
- Distillation – Your last option are water distillers that, strictly speaking, don’t belong to the group of water filters. However, they provide an effective way of removing fluoride from drinking water, which is why we don’t want you to miss out on them.
Although not on the list, bone char is another water filter media with high fluoride adsorptive capacities. Produced by charring mainly cattle and pig bones, the porous, granular material consists of tricalcium phosphate, calcium carbonate, and carbon. Tricalcium phosphate is what removes the fluoride.
What is a Fluoride Water Filter and How Does It Work?
Fluoride water filters use reverse osmosis, strong base anion exchange, activated alumina adsorption, or distillation for effective fluoride removal.
The filter can be in the form of a reverse osmosis system, a water filter pitcher, a whole house water filter, an under sink or countertop filtration system, a water filter bottle, a shower filter, an inline water filter, or a water distiller.
The most important advantage of using a fluoride filter is that your drinking water will be much healthier – and taste much better.
What Are the Different Types of Fluoride Water Filtration Systems?
RO Filter Systems
RO filter systems apply a multi-stage filtration process to remove more than 90% fluoride from drinking water. They key filter element is the semipermeable reverse osmosis membrane at the heart of each system. It does the bulk of the contaminant removal.
Water Filter Pitchers
A water filter pitcher is ideal for drinking water filtration. Sophisticated models use a combination of different filter media to remove many different contaminants including fluoride.
Whole House Water Filters
Whole house fluoride water filters are rare. That’s because effective fluoride filtration at scale is extremely difficult. The Crystal Quest which is our favorite system uses a large mineral tank filled with bone char to achieve 90-95% reduction.
Under Sink Systems
Just like reverse osmosis systems, regular under sink water filters use multiple filter stages to reduce fluoride in your drinking water.
Water Filter Bottles
Believe it or not, we found one water filter bottle based on Affinity filtration technology that removes 99.0-99.9% fluoride. The water gets filtered as you suck it through the straw.
Gravity and Countertop Water Filters
Gravity and countertop water filters are the pendant to under sink fluoride filter systems. They use one or more stages of filtration in order to provide healthy and clean drinking water.
Shower Filters
We are still waiting for shower water filters that remove fluoride effectively. So far only the Propur ProMax looks relatively promising, achieving around 50 percent reduction.
Inline and Refrigerator Water Filters
Regular refrigerator water filters don’t remove fluoride. However, there is one inline water filter that does. It uses a single filter cartridge based on ion exchange.
Water Distillers
As mentioned earlier, water distillation provides a very effective way of removing fluoride from the water we use. Basically, they heat the water in a boiling chamber until everything has evaporated. All contaminants are left being.
Advantages and Disadvantages of Using a Water Filter to Remove Fluoride
Advantages
Fluoride-Free Water
A fluoride filter will help you get access to fluoride-free drinking water.
Other Contaminants Will Be Removed
A filtration system will not only filter fluoride, it’s probably also effective against many other types of water impurities. As a result, your water will likely be a lot healthier.
Improved Drinking Water Taste
Filtered water also tastes much better.
Cost-efficient
Unless you are thinking about getting a whole house filtration system, fluoride filter costs are manageable.
Convenient
Most fluoride filters are easy to install, use, and service.
Disadvantages
Insufficient Removal
Most water filters are not NSF tested or certified for fluoride removal. That’s why it’s so important to check for specific fluoride reduction rates.
Frequently Asked Questions (FAQ)
- What are the most trusted fluoride water filter brands?
We’re not sure if there even is a water filter brand most trusted for fluoride filtration. Our favorite products are listed above. They’re the most effective currently on the market. - How to make a fluoride filtration system?
We wouldn’t recommend trying to create your own fluoride water filter system. A) It’s likely that you won’t succeed and B) it’s simply not worth the effort. Just buy one! - Does my system filter fluoride?
You should check its performance data sheet. Testing according to NSF Standard 58 usually includes fluoride removal capabilities for reverse osmosis systems. For non-RO fluoride filters, any reduction rates were determined in non-standardized testing (which isn’t necessarily a bad thing). - Brita, PUR, ZeroWater, LifeStraw – Do they reduce fluoride?
Some of the most popular water filtration systems, PUR and Brita pitcher filtration systems among them, will not filter fluoride out of your water – the reason being that both PUR and Brita (pitcher) filters use carbon to trap impurities which doesn’t have any effect on fluoride. As for LifeStraw, it only filters bacteria, protozoa, and viruses. The ZeroWater water filter pitcher achieves an average fluoride reduction of 99%. - Do water softeners remove fluoride?
The sole purpose of a water softener is to soften water. It has no effect on fluoride. That’s just not what the softening resin was designed to do. - Can you boil fluoride out of water?
No, you can’t. Boiling does not affect fluoride because it doesn’t evaporate easily.
