3 Best Fluoride Water Filters In 2026 (61+ Brands Tested)

After personally testing 61+ water filters for fluoride, I’ve narrowed it down to the best 3.

Important information considering not all water filters can remove fluoride and many companies falsely advertise their filters can. But fear not, I will help you choose the best fluoride water filter for your needs and budget.

Warning About “Fluoride” Water Filters

The unfortunate truth is that if you trust a brand or read “reviews” from other websites, you’ll probably get a “fluoride” water filter that can NOT remove fluoride.

And since I can not talk about every single filter, I’ll share the fluoride test results of all 61+ filters I’ve tested (pitchers, shower filters and even whole house filters). This way in case you buy a filter I don’t recommend, you can double check if it can remove fluoride.

All you have to do is enter your email below and I’ll send it to you right away.

Best Water Filters That Remove Fluoride (61+ Brands Tested)

While you’re reading my top picks, you may think there are not many options to choose from.

But that’s the point.

There’s no need to over complicate it and bombard you with too may options. I’ve done all the dirty work. I bought, tested and personally used every single water filter. Making it very easy to choose the right one…

You either want 1 of these 3 options.

• a pitcher,
• countertop filter, or
• a filter to stick under your sink

Those are my top 3 fluoride water filters, and in the next 5 minutes I will talk about each one in more detail (how it compares to other choices) to help you find out which filter is best for you.

Best Fluoride Water Filter Pitcher

Pitchers are the most popular type of water filters but not all brands can remove fluoride.

For example, Brita filters are the most well-known but have no effect on fluoride. However, even certain Amazon best-selling “fluoride” water filter pitchers claim they can filter fluoride but actually have zero effect (Aquagear, Epic Nano, Waterdrop – just to name a few)

In fact, you can probably count on one hand how many pitchers can remove fluoride.

So if you’re looking for a pitcher that CAN remove fluoride, the best option is Clearly Filtered. Plus their filters are built in the USA which is very rare, since most companies just sell cheap knockoffs imported from abroad (to put it nicely).

And since I’ve helped 1000’s of people purchase it, I’ve tested Clearly Filtered at least 5 different times with my own fluoride meter and laboratory tests. Each time it was able to completely remove fluoride from my tap water.

The only drawback is price. It seems like one of the more expensive pitchers but when you consider Clearly Filtered lasts for 100 gallons and others brands only for 25-50 gallons before filters need to be replaced. It does save you money down the road.

Note: if you plan on buying the pitcher, you should buy from Clearly Filtered (link to their website) and not Amazon. The price you pay will be cheaper (around $10 or more in savings if you do subscribe and save) and shipping time is the exact same.

Best Countertop Fluoride Water Filter

This section holds my next favorite fluoride water filter.

Which would be AquaTru Carafe (link to the product). It truly is my dream product, it has none of the negative features a typical reverse osmosis filter would have (discussed below). But has all the positives like doing an amazing job at filtering all toxins, including fluoride.

For example, the AquaTru Classic uses the exact same filters as the Carafe model and when I filtered Starkey bottled water that has 0.8 ppm of fluoride (more than tap water) it reduced 100% of fluoride to 0.0 ppm.

But the reason why I like the Carafe model more, is that it has a class pitcher that the filtered water is stored in. So you don’t have to worry about any negative effects plastic could have.

Lastly, installation and maintenance is very easy and straightforward with this filter.

You take it out of the box, place the filters into their spot, plug it into an outlet, press a button and it starts transforming your toxic tap water into the best quality filtered water possible.

But I can’t stress this enough, the beauty of this product is when you compare it to traditional reverse osmosis systems or other reverse osmosis filters like WaterDrop that do not filter water properly. Which I will explain in more detail below.

WORST Fluoride Water Filters (100% Avoid)

When it comes to the best fluoride water filters, there aren’t many that can beat a Berkey.

It’s easy to use, requires minimal installation and filters water extremely well. Not to mention, it feels like almost every Instagram health influencer under the sun has recommended them.

Or so, that’s what I thought…

When I tested the Berkey, it was able to reduce fluoride levels from 0.6 ppm all the way down to 0.0 ppm. So in regards to fluoride, it “seems” like it’s doing a great job.

BUT after further research and tests, I’ve uncovered a few red flags that have forced me to withdraw Truth About Fluoride’s approval for Berkey. With the biggest red flag that it leaches “aluminum” into your filtered water.

Now everything I’ve said about Berkey was technically true, sure it “removes” fluoride according to a fluoride test, sure their filters last longer than other brands, and sure they’re one of the “best” gravity fed fluoride filters – but there’s more to it than that.

Especially when you consider the goal of my website is not only to give you great advice in regards to fluoride but to also give you advice that is good for your overall health.

What’s the point of dodging fluoride if this advice does not consider other factors.

Now it’s a shame that we have to continuously test brands to figure out if they’re legit and safe but I guess that’s what we have to do. And I’m happy to play my part in exposing these brands.

So when it comes to fluoride water filters, your best and safe choice is to go with Clearly Filtered or AquaTru. And Berkey is definitely one you should 100% stay away from. I also discuss other brands to stay away from in the 61+ filter report you can sign up for above but Berkey takes the cake for the worst.

Best Water Bottle Fluoride Water Filter

Out of the 6 water filter bottles I bought and tested, the only one that could remove fluoride was Clearly Filtered (link to product). Taking fluoride levels in my tap water from 0.6 ppm to 0.0 ppm.

While all other bottle filters had no effect on fluoride. Since their main focus is on improving the taste of your water instead of actually improving the quality by removing toxins.

Best “Under Sink” Fluoride Filters

Most people think reverse osmosis is the best way to filter water.

Now if you have a quality reverse osmosis system, this is kind of true. It does purify your water, removing everything inside it. It also does it for very cheap, on average costing 10 cents per gallon filtered.

And after the difficult installation, all you have to do is turn on the tap and you’ll have filtered water, whenever you want it. Unlike Clearly Filtered or AquaTru where you have to manually fill it up… Plus you get the water extremely fast. For example, it takes about 30 seconds to fill up an entire kettle (pictured below).

I also have a reverse osmosis system from APEC under my sink.

I still love to use it for rinsing my rice, washing vegetables and other tasks that require a more convenient source of filtered water. But for the reasons discussed below I’m not the biggest fan on recommending it blindly anymore.

Negatives About Reverse Osmosis Systems

This is not your typical criticism of reverse osmosis. I’m not going to talk about how it strips your water of minerals or how it “wastes” water.

1. Difficult installation and setup process

This is not the biggest negative especially if your good at these activities. But your traditional reverse osmosis system like APEC or HomeMaster requires basic plumbing knowledge and being able to drill a small hole into your countertop to install the faucet.

And after helping 1000s of people get started with various filters, this seems to be a big headache for many. While if you rent where you live, you’ll need your landlords permission.

2. Possible leaching of plastic into filtered water

I’ve never heard anyone speak of this but it’s something to keep in mind.

Once your reverse osmosis system filters water, the filtered water sits in a storage tank. This storage tank is made out of Butyl rubber and lined with a plastic called polypropylene. Considering reverse osmosis is acidic, it’s reasonable to assume it could leach some of that plastic lining into your filtered water.

Again this is not a huge concern, but if I had the option to get a different filter like the AquaTru discussed above. That’s what I would go for, just for the peace of mind.

3. Possible mold or bacterial growth

Another possible concern is the growth of mold or bacteria in the storage tank or other parts of the filter like the post-carbon filters or tubing. But if you properly maintain the filter and clean it once in a while, this should not be an issue.

But it does require some effort on your part.

And what I’ve noticed with the people I help and including myself, it’s easy to just ignore and put it off. Since you can not see what’s going on inside the filter and it requires at least an hour of work to clean. But this is a great video on how you’d have to clean it.

4. Tankless Reverse Osmosis Systems Issues

The most logical thought would be to look towards RO systems that do not have a storage tank.

That should solve the issue? But unfortunately, RO systems that give you water on demand filter water too quickly to properly “catch” all the toxins you want removed from your water.

That’s why when I tested a tankless reverse osmosis system like WaterDrop, it was only able to remove 50% of the fluoride in my water. Only reducing fluoride levels from 0.6 ppm to 0.3 ppm (pictured below)

However, WaterDrop advertises their filters can remove much more fluoride than 50%. Misleading their customers. Which happens with not just them but many other tankless reverse osmosis water filters.

Which filter should you get?

I’ll keep it super simple.

If 1-3 people are using the filter, Clearly Filtered pitcher is a great option. It’s the best pitcher by far. While if you have a small family or want something more high end, the AquaTru Carafe would be my second choice. That’s it, I would keep it between those two options.

Only time I would consider a third option would be reverse osmosis from APEC or HomeMaster. But only if you are okay with the installation that requires basic plumbing skills, drilling into your countertop and are willing to properly maintain the filter.

So those are my 3 best fluoride water filters.
