When I learned about the bad effects that fluoride can have on our health, I knew that I had to do something to protect myself and my family.
Maybe you feel the same way.
If you're not sure how to reduce the fluoride in your water, you've come to the right place. In this review we'll cover different types of water filters that will get rid of the fluoride in your drinking water. Plus, there's even a fluoride water filter for shower heads I want to tell you about.
You'll also find mini reviews of the specific models that I recommend in each category.

Each of these brands has its advantages and disadvantages, but they all do the job of reducing fluoride. I hope that the information in this guide will help you to decide which is the best one to meet your needs.
Water Filters That WON'T Reduce Fluoride
First, let's talk about what doesn't work.
All water filters are not made equal.
Most pitcher type filters like Brita and Pur may make your drinking water taste better, but they don't take out fluoride. The same goes for most faucet mounted filters and many under sink water filtration systems. They use activated carbon, usually made from coconut shells.
If a filtration system only has an activated carbon filter, it will not work on fluoride.
I have read that activated carbon can remove 40 to 60% of fluoride in water, but it loses its effectiveness in a very short time. That's why I don't recommend carbon block filters for fluoride filtration.
The good news is there are much more reliable methods to choose from.

Reverse Osmosis Fluoride Filters
How does RO work?
A reverse osmosis filter system involves sending tap water through a series of carbon block filters and a reverse osmosis membrane.
This filtration system is connected to the cold water plumbing in your house, and it uses water pressure to push the water through the system. In the process, the contaminants are collected in a brine which goes down the drain.
The components are all installed in the cabinet space under the kitchen sink. A small storage tank holds the filtered water until you turn on the dedicated faucet that's mounted on the sink.
Most RO systems have 4 to 6 stages that the water goes through, although I've seen as many as ten! Sometimes, besides the basic filtration, they add on some extra steps like the addition of minerals, exposure to ultraviolet light, and ozonation. Of course, the more stages a system has, the higher the cost.
Here's a diagram illustrating a basic RO system setup:
Reverse Osmosis Pros and Cons
Best Reverse Osmosis Filtration System for Fluoride: APEC RO-90
APEC is an American company with an excellent reputation for making the highest quality water filtration systems.
Their most popular model is the RO-90. It's a 5-stage system that can put out up to 90 gallons of filtered water a day.
Fluoride is reduced by 97.7% with an APEC RO filter.
APEC also makes other models for different needs:

All RO filtration systems will reduce the fluoride and give you good clean drinking water. If you'd like to learn about even more options, please see my review: The Absolute Best Reverse Osmosis Systems for 2022.
Gravity Fluoride Filters
How does a gravity filter work?
A gravity filter is a very simple system. It's made up of two containers, one stacked on top of the other. Two or more filter elements are housed inside. Different brands use different media for filtration.
To use it, you pour water into the top container and gravity pulls the water down through the filters into the bottom container. A spigot in the bottom part allows you to dispense the water.
Please note that not every gravity filter can act as a fluoride water filter. Be sure to check the specifications before you buy.
Gravity Filter Pros and Cons
Best Gravity Filter for Removing Fluoride: ProOne Big+
The Big+ (that's Big Plus) is one of several sizes of gravity filters made by ProOne. You might know ProOne by its former name, Propur - the company changed the name at the beginning of 2021.
They also made a few minor changes to the stainless steel component, but the ProOne filter technology hasn't changed.
It holds 3 gallons of water, so it's good for a group of 4 or more. You could use it for a big group, but that would mean refilling it more often.
A ProOne filter system usually comes with two filters, but you can add another one to speed up the filtration. Each filter consists of granular activated carbon encased in a silver infused ceramic shell.
The typical reduction of fluoride is about 96%. It targets all three forms of fluoride: sodium fluoride, hexafluorosilicate, and fluorosilicic acid. (See lab test results here.)
ProOne is also excellent at removing lead, chlorine, chloramine, bacteria, viruses, and many other toxins.

Water Distillers for Fluoride Removal
How does a water distiller work?
There's an interesting way that distillation differs from filtration.
Instead of removing contaminants from the water, the process of distillation removes the water from the contaminants. That sounds similar, but it's not the same.
A distiller boils the water and turns it into steam. Chemical contaminants, including fluoride, are left behind. The high temperature also kills any biological contaminants like viruses or bacteria. As the steam cools, it turns back into pure water, which is collected in some kind of container.
I've had a hard time nailing down the exact percentage of fluoride reduction by distillation. Most everything I have read says that distillation removes "a high percentage" or "most, if not all" fluoride from water.
Water Distiller Pros and Cons
Best Fluoride Removing Water Distiller: Megahome
The Megahome Countertop Water Distiller Model MH943TWS is a popular model. It's well constructed and made of high quality stainless steel, enamel coated steel, and glass. Only the handle and lid are made of food grade polypylene. But the water never touches any plastic because the nozzle is made of glass.
Because the distillation process takes about 5 to 6 hours, you'll only be able to make a maximum of 4 gallons per day.
Fluoride is removed completely or almost completely using the Megahome distiller.
I've also written a detailed review of the Megahome distiller if you'd like more information.
You can also see Best Home Water Distiller Options for the details on some other top brands.
Pitcher Style Fluoride Filters
How do filter pitchers work?
Filter pitchers have a simple setup. There are three main parts: the pitcher, the reservoir, and the filter.
The filter is attached to the reservoir. You fill the reservoir with tap water, and the water seeps through the filter and drips down into the pitcher. Contaminants are blocked and collected in the filter.
Because the filter collects the contaminants, it eventually gets clogged up and stops filtering. That's why you have to replace it every now and then.
Water Filter Pitcher Pros and Cons
Best Fluoride Water Filter Pitcher: Clearly Filtered
I said above that most pitcher style filters aren't any good for fluoride filtration. Well, the Clearly Filtered is one that does take out fluoride.
This pitcher holds 2 quarts of water, and the filter will last for about 3-6 months, or 100 gallons. It does an amazing job of removing lots of harmful contaminants from drinking water, including lead, chromium-6, and, of course, fluoride.
Fluoride reduction with the Clearly Filtered pitcher is 98%.
The Clearly Filtered is also available at the Clearly Filtered website with free shipping. There's also an option to save 10% on replacement filters by signing up for their subscription service.

Clearly Filtered has recently added an insulated stainless steel filtered water bottle for kids to its lineup! It's a great way to ensure your kids are drinking fluoride free water while they're away from home.

Best Under Sink Water Filter for Fluoride Removal: Clearly Filtered
So, what's the best fluoride reducing filter that goes under the sink, but isn't an RO filtration system? Well, your options are fairly limited. But, they do exist, and the one that reduces the most fluoride is made by Clearly Filtered.
The Clearly Filtered 3-stage under-the-sink filtration system installs quickly and easily under your kitchen sink. I know it's easy because I did it myself!
It hooks up to the cold water line, and it uses your existing faucet. So, you won't have to drill an extra hole for a dedicated faucet. The disadvantage is that there's no bypass, so all the cold water is filtered - not just your drinking and cooking water.
This model reduces fluoride by 99.5%, and the filter life is 2,000 gallons, or about one year.
You can take 10% off the price when you order at Clearly Filtered.com by using the code SAFEHEALTHYHOME2020 at checkout.
To learn more about the Clearly Filtered, you can read my Hands On Review of the Clearly Filtered Under Sink Water Filter.
A second under counter filtration system brand you might consider is the ProMax FS10 from ProOne. The fluoride reduction isn't quite as good as Clearly Filtered - 88% vs 99.5% - but it's a little less expensive.
You can check out the ProMax FS10 at the ProOne USA website.
Best Refrigerator Fluoride Filter: Clearly Filtered
There are a couple of fridge filters that are good at removing fluoride.
First is the Clearly Filtered Universal Inline/Refrigerator Filter.
A second model to consider is the ProOne Promax Inline Refrigerator Filter. (ProOne is the new name for Propur, as of January 2021.)
Faucet Filters Don't Work on Fluoride
There's not a single faucet mount filter I'm aware of that is capable of fluoride reduction. I had reviewed one called the iSpring LittleWell that could do it, but that model was discontinued. I'm not a fan of faucet mount filters, anyway.
Best Fluoride Shower Filter: ProOne (formerly Propur)
So maybe you have a filtration system for your drinking water. But you might be concerned about absorbing fluoride through your skin. If you also want to do something about the fluoride in your shower water, I have good news for you.
There is one shower filter that reduces fluoride: the ProOne. It's the only brand that I've found that works on fluoride.
According to independent lab test data, it removes 48.2% of sodium fluoride, 43% of hexafluorosilicate, and 48.1% of fluorosilic acid. The reason the reduction rate is so low is that water passing through the shower has only brief contact with the filter medium.
So, this shower filter can't completely eliminate fluoride from your shower water, but it can cut it almost in half. Your only other solution would be to install a whole house fluoride water filter.
You can find more information about the ProOne shower in my review of the best shower head filters.
Conclusion: Use Care When Choosing a Fluoride Filter
I don't think I can say that one particular filter is the best fluoride water filter. All of the filters I've mentioned will do a good job of removing the fluoride from your drinking water.
Which type of water filter, and which particular model would be best for you is really a matter of personal preference based on the other features.
The first decision to make is whether you want an installed filtration system or a portable system that can be used at home and away from home.
If you want an installed RO system, think about what your special needs might be. How good is your water pressure? Do you have a medical condition that requires your drinking water to be alkaline? Make sure the filtration system you choose addresses those issues.
If you're more interested in portability and in being prepared for emergencies, you'll probably want to go with a gravity filter or a pitcher filter. The gravity filter can handle a much larger capacity, though.
A distiller is easy to transport, but you have to be able to plug it in. It's also very slow. Definitely not good for emergencies, but it's suitable for everyday use for one person or a small family.
I hope you've found this helpful in deciding which is the ideal filtration solution for your situation.
