The addition of fluoride to drinking water is a contentious issue. If you’re concerned about its effects, investing in a fluoride water filter can be a good option. But how do you know which one to pick from the many on the market?
We’re here to help demystify the different features available. Check out our reviews of the best fluoride water filters available right now. Then take a look at our buying guide to help decide which is the right fit for your home.
Woder’s system is designed to be used with cold, treated drinking water.
In addition to removing 95 percent of fluoride, it will extract a wide range of other contaminants. These include chromium, lead, arsenic and 99 percent of chlorine. If your water has a chemical flavor or odor, this could be an effective cure.
The filtration system is independently tested by the Water Quality Association. And unlike reverse osmosis systems, it will leave essential minerals like calcium and magnesium in your water.
The filters here are long-lasting. They’ll treat around 8,000 gallons of water, lasting for at least two years for an average household. That’s considerably longer than many other systems.
There are, though, some things that can interfere with that long life. If you have hard water and use a softening system, the salt will reduce the filter’s longevity. They’re not designed to be used with well water or hot water either.
Installation is very straightforward. The package comes with everything that’s needed. That’s a stage 1 and 2 filters, inlet and outlet hoses to fit standard pipes and a quick mounting head. It even comes with the necessary screw.
It can be installed on your cold water faucet or attached to a separate faucet if you prefer. Handy videos are available to help with the process. And it will fit non-standard plumbing too.
One thing to bear in mind is that you’ll almost certainly find that the filter reduces the water pressure. Woder says that this is because the filter needs to be very fine in order to remove fluoride.
It’s supposed to produce a flow rate of three gallons per minute – but that doesn’t always happen in practice. If you have low water pressure in the first place, this might not be the best choice.
Installing a separate drinking water faucet to which to attach the filter is a good option. That will allow you to keep faster flow rates for cold water that won’t be used for drinking or cooking.

Big Berkey’s countertop water filter system comes with fluoride filters as part of the package.
It consists of two stainless steel containers, one on top of the other. The filtered water is extracted from a spigot at the bottom.
The water is filtered by black purification elements. Two of these are included as standard, and there’s space for a further two to speed up the process. These will remove bacteria, cysts and parasites, making it possible to use this with lake or river water.
The system also reduces chemicals including solvents, pesticides, herbicides and nitrates, and reduces levels of lead and mercury. Each of the main filters will treat around 3,000 gallons of water.
The fluoride filters attach to the main filters and will extract 95 percent of fluoride. You will, though, need to change them more regularly. They’ll treat around 1,000 gallons of water before needing to be replaced.
All the work here is done by gravity, so you won’t need to connect the system to electricity. And there’ll be no need to worry about running out of drinking water during a power cut.
You won’t, though, have filtered water on tap. You’ll need to fill the container from your water source and wait for filtration to take place.
The capacity is 2.25 gallons. That’s pretty generous – but remember that you’ll need to fill the upper canister and set it in position. When full of water, it’s pretty heavy.
The flow rate is decent, providing up to 7 gallons an hour with the system kept continually topped up. You’ll find it filters fastest when the top container is full, and gets gradually slower as the water level drops.
As a standalone system, there’s no plumbing in needed. You’ll need to do a little assembly, but it’s very easy. Expect to spend about ten minutes doing it, and you won’t need any tools.
One thing to remember with this system is that the purification elements must stay wet. If they dry out filtration will get much slower. More importantly, dry filters can be havens for bacteria. If you’re going on vacation, ask a friend or neighbor to keep your filter topped up.
Filters fluoride and other contaminants
No power source or plumbing-in needed
Good flow rate from the spigot
Water supply is limited to 2.25 gallons at a time
Needs daily use to keep the filters wet and prevent bacteria growth.
It consists of a stainless steel barrel 5 inches high and 3.5 inches in diameter. There are no plastic parts, so you won’t need to worry about chemicals leaching into the water. It’s nice and robust and won’t corrode.
This fixes on to the end of your faucet. Water filters through six layers before being released. The layers include activated carbon, tourmaline and maifan medical stone.
The result is water from which Homy say 99 percent of fluoride has been removed. The filter will also extract lead, chlorine and sediments. If you have city water and find it smells or tastes of chemicals, this could be a good choice.
It won’t, though, work in every home. You’ll need a conventional faucet to attach it to. If you have a sensor or pull-down faucet, or anything with an irregularly shaped end, it won’t fit.
Otherwise, this is easy to install and use. The package includes a range of connectors to attach to different types of hoses. You won’t need any tools for installation either.
You’ll need to run the water for about a minute before first using it. That will get rid of any specks of carbon loosened during transit. After that, the water is ready for drinking.
Two outlets mean it’s simple to switch between filtered and unfiltered water. The flow rate for the filtered water is half a gallon per minute. That’s enough to fill ten small cups.
Flick the switch when you want water for cleaning or washing up. You won’t have to use up your filter stripping impurities out of water when it isn’t necessary.
Each filter will treat around 320 gallons of water. For an average household, that will last for around three months. That compares favorably to other faucet-mounted filters.
Handles fluoride and a range of other contaminants
Easy to switch between filtered and unfiltered water
Simple to install and provides filtered water on tap
Won’t fit pull-down, sensor or other non-standard faucets
The filter life of three months is good for faucet-mounted filters – but other types of system will last longer.
A similar design to the Big Berkey, Propur’s Traveler countertop filter system is another that uses gravity to filter water. In this case, the stainless steel containers are slightly smaller, making this a portable option.
The system will filter up to 1.6 gallons in one go. It’s a good choice for households of one to two people, and it won’t take up too much room in your kitchen. It stands 18.5 inches high and its base is 7.5 inches across.
The whole thing is made of high-quality stainless steel. That includes the spigot, making this a very resilient design. It will stand up to outdoor as well as indoor use.
There is, though, one weak point in the design, and that’s the knob on the lid of the upper canister. If you tighten it beyond the point at which it’s just snug, you might find it snaps off.
The Traveler includes a single candle filter. A ceramic case encloses a core of activated carbon. The ceramic can be cleaned easily, extending the life of the filter. Inside, the granulated activated carbon will extract more than 220 contaminants including fluoride, lead and microplastics.
It’s heavy-duty enough to deal with water from streams and lakes, as well as from your faucet.
The base of the filter is made of plastic, but it’s free of BPA. It screws tightly in place, preventing any unfiltered water from leaking into the filtered water canister.
Expect the filter to treat between 300 and 400 gallons of water before needing to be replaced. Removing it about once a month and scrubbing the ceramic with soapy water will optimize its life.
The filters here are infused with silver. That will help keep bacteria at bay, but it’s still best to keep them wet.
You’ll need to flush the system through before drawing your first drinking water. And like other countertop filters, remember that you’ll need to fill the canister and lift it into position. The smaller capacity of the Traveler makes this less heavy work than some other models.
Ceramic filter will remove over 200 different contaminants
Silver-infused filters inhibit the growth of bacteria
Compact design works well where space is limited
The knob on the upper canister is prone to snapping off if over-tightened
Limited capacity of 1.6 gallons of filtered water at a time.
If you’re looking for a simple, economical solution to filtering out fluoride, a filter pitcher is well worth considering.
Reshape’s model will hold 10 cups. It stands 10.5 inches tall and is 10 inches wide, including the handle. The narrow design means it will fit comfortably into the door of most refrigerators. It’s made of ABS plastic, so it’s shatterproof. And there’s no BPA to leach into the filtered water.
The pitcher comes with a filter and a spare. Each has six different layers.
There’s a pre-filter membrane to remove silt and sediment. The water then passes through a layer of ion exchange resins, activated carbon, FAR infrared balls and negative hydroxyl ions. Finally, there’s a post-filter membrane to remove any lingering impurities.
All this will remove or reduce fluoride, chlorine, lead and volatile organic compounds. At the same time, it will add trace levels of magnesium, sodium, calcium and potassium. The result is slightly alkaline water – great for anyone with a sensitive digestive system.
Unfiltered water goes in at the top. The upper reservoir will hold 55 ounces. The water will filter through the different layers at a rate of about three gallons an hour. The bottom reservoir holds the filtered water and has a capacity of 84 ounces.
That’s about as big as you can get whilst keeping the pitcher light enough to be handled easily.
Each filter will last for between 60 and 75 days, during which it will purify around 79 gallons of water. The two filters included in the pack will therefore give you between four and five months of filtered water.
And if you’re worried about remembering when to buy a new filter, don’t be. A handy indicator in the lid of the pitcher counts down from 60 days.
There are just a couple of things to be aware of with this one.
The first is that the filter rate is fairly slow. And you’ll need the water to have finished draining through the unfiltered reservoir before pouring. Topping up the pitcher regularly is better than leaving it until it’s empty and then refilling.
The second is that the filters need to be soaked twice, for ten minutes each time, before the first use. That means filter changes are more time consuming than we’d like.
But set aside these minor niggles and this is a simple and cost-effective way to get rid of fluoride.
Cost-effective and easy to use
Comes with two filters, providing 4-5 months of filtered water in total
Conveniently shaped to fit in most refrigerator doors
Filters fairly slowly – and you won’t be able to pour while there’s unfiltered water inside
If you’re looking for an intensive approach to water purification, reverse osmosis could be the right choice. Aquasana’s OptimH20 system combines reverse osmosis with advanced filtration and remineralization.
As a result, it will remove 95 percent of fluoride. It will also extract 97 percent of chlorine. And it will virtually eradicate over 80 other substances, including any lead, mercury or pharmaceuticals present.
One of the main concerns about reverse osmosis is that it’s too robust as a means of filtration. It will remove almost all particles from water, including beneficial minerals like magnesium and calcium.
With this system, your water passes through a remineralization stage to put that right. It will return healthy amounts of potassium, calcium and magnesium. This will make the water both taste better and be kinder to your gut.
The system sits under your sink and attaches to its own dedicated faucet. The faucet is available in a range of finishes – brushed nickel, chrome and oil-rubbed bronze – to complement your kitchen décor.
The elegant, high-arcing design stands just under 9 inches high. Some people have, though, found that it’s not as heavyweight as their main faucet.
The package includes the first set of filters, the reverse osmosis tank, faucet, and all parts needed for installation. The job is surprisingly straightforward. The instructions are clear, and if you’re a reasonably competent DIYer there’ll be no need to call in a plumber.
Maintenance is simple too. The filters twist out and snap back into place for easy replacement.
The major thing to bear in mind with this is that reverse osmosis systems produce a lot of wastewater. With this system, three gallons of wastewater will be produced for every gallon of treated water. If you’re in an area of water scarcity, or have a metered charge, this won’t be the right choice.
Reduces 95 percent of fluoride plus a wide range of other contaminants
Includes remineralization stage to replace essential minerals extracted by reverse osmosis
Installation and maintenance is straightforward, and you’ll have filtered water on tap
If you’re looking for a system to attach to your existing faucet, Clearly Filtered’s model could be for you.
The three filter cartridges sit neatly beneath your sink. They will eliminate an impressive 99 per cent of fluoride and achieve the same level of chlorine capture. And the system will tackle over 200 other contaminants too. (Just remember, they’re unlikely to all be in your water in the first place.)
The filters will treat 2,000 gallons of water before needing to be changed. That’s roughly 9 months’ use for a large family or 12 months for a small family or couples. Single users can extend that to around 15 months.
You’ll need to rely on these guidelines, though, to decide when to change them. Some under-sink systems have individual gauges for each filter. That’s not the case here. In fact, there’s no gauge at all.
It installs easily in about 15 minutes, no tools required. But perhaps the neatest feature about this system is that it can be removed just as easily. If you’re renting or in temporary accommodation, it’s a great choice.
With this system, though, all your cold water will be filtered. You won’t be able to turn it off to prolong the life of your filter.
And you may find that the filtering process results in lower water pressure at your faucet. As there’s no way to turn it off, be prepared to wait for a while if you need to fill pitchers or buckets.
But as long as you can handle this, you’ll be getting excellent quality water. And it will keep running as long as the faucet is open.

So you’ve read all the reviews but you’re still not sure which is the best fluoride water filter for you. Don’t worry – our buying guide is here to help! Read on as we consider the things to look for before you make your final choice.
On tap or batch filtration?
The first thing to ask yourself is whether you need an unlimited supply of filtered water. If the answer is “yes”, you’ll need a filter system that fixes to your faucet.
There are two options here: systems that fit under the sink, or those that attach to the faucet itself. Under-sink versions usually offer more rigorous filtration, but they’ll take up space in your cupboard.
If you can afford to wait between batches of filtered water, a pitcher or countertop system could be the answer. These tend to be less expensive, and you won’t have to worry about plumbing them in.
Just remember that water is heavy. With countertop systems, you’ll need to be able to fill the top canister and move it into position. And make sure that any pitcher strikes the right balance between generous capacity and manageable weight.
How often are you prepared to change filters?
Filter life varies widely between different systems. Filters can be expensive, so consider how often you’ll need to replace them when comparing costs.
For filters with longer lifetimes, a gauge to remind you when it needs to be changed can be very useful. You won’t need to worry about drinking water that’s no longer as pure as it could be. And you won’t have the expense of replacing filters before you need to.
Look for filters that are easily removed and replaced. And be aware that some need to be flushed for a lengthy period before use. If that’s hassle you can do without, look for other options.
Do you want all your water to be filtered?
Remember that not all water needs to be filtered. There’s no point in using up your filter life on water that’s destined to mop the kitchen floor.
All filters will affect water pressure to some extent too. Some faucet systems will allow you to switch back to unfiltered water. That means you won’t have to hang around to fill a bucket for cleaning. And with pitchers or countertop filters, you’ll only be filtering the water you need.
Ready to choose?
That brings us to the end of our review of some of the best fluoride water filters on the market. We hope it’s helped you choose the one that’s right for you.
