Best Fluoride Water Filter 2023: Top Picks, Reviews & Guide

fluoride water filter systems

Shopping for a Fluoride Water filter for your home?You’ve come to the right place. 

Fluoride is widely used in community water supplies as a disinfectant. But not everyone is comfortable ingesting it.

If you too are someone who prefers to avoid ingesting fluoride or have trouble ingesting it, then what you need is a fluoride water filter.

Fluoride-removing water filters can be attached to the tap system, or you can use them in a standalone configuration.

What Kinds of Water Filters Can Remove Fluoride?

It is impossible to completely remove fluoride from water byjust boiling it, which is why many people turn to comprehensive processes such as water filtration. 

But a traditional water filter is simply not enough to lower the fluoride concentration of water. 

You will require a specialized fluoride water filter which you can choose from a wide range of options in the market these days. 

The kinds of water filters that can efficiently remove fluoride from water include:

Reverse Osmosis

Out of the many filter systems used today, reverse osmosis water filters happen to be the most popular choice since they are known for effectively removing 85-90% of fluoride from drinking water.

An RO filtration system is connected to the water supply system, where it uses household water pressure to push tap water through a series of membranes.

Most reverse osmosis filtration systems have 4 semi-permeable membranes that allow water molecules to pass while filtering out the contaminants present in the water. 

These filters are a cost-effective solution for removing fluoride and other contaminants, including lead and sulfates, from the water and making it clean, pure and safe for consumption.

Bone Char Carbon Filter

If you want a fluoride water filter for purposes other than drinking, a bone char carbon filter is the best option for you.

Bone char carbon filters come as water filter cartridges that eliminate approximately 90% of the total mineral content from the water.

However, their efficiency at reducing fluoride significantly drops after they have filtered certaingallons of water.

Moreover, bone char is made by heating animal bones at high temperatures, making these filters unsuitable for vegans.


Distillation is another effective and affordable way to remove fluoride from water. You can easily find a countertop distiller for this purpose.

However, the distillation process removes the beneficial minerals from the water too. 

Moreover, for people accustomed to drinking chlorinated water over a long period, distilled water might taste flat.

Activated Alumina Filter

Activated alumina is a porous, solid form of aluminum oxide. It is an inert and non-soluble filtration media that neither loses its efficiency nor requires the use of antifungals.

Activated Alumina filtration is EPA-recommended and is highly effective at absorbing fluoride and other contaminants from water.

But it has its limitations too. For instance, it only works on water with a pH of less than 8.5. For effective fluoride removal, the pH should be between 5 and 6.

Best Whole House Fluoride Water Filter

The iSpring RCS5T RO Water Filter System provides fluoride-free water throughout your house. 

It is a 5-stage water filtration system that removes up to 99% fluoride with its reverse osmosis water filtration process.

The iSpring RCS5T features a tankless design that produces clean water on demand and has a large capacity of 500 gallons per day. 

Its 1:1 wastewater ratio also ensures that minimum water goes down the drain.



Our Review

The iSpring RCS5T RO Water Filter System is one of the affordable fluoride filters currently available on the market. It features a compact design that fits in most spaces.

This fluoride filter from iSpring comes with its own metallic frame that houses all the different filtration stages and the pressure pump. So, there is essentially no assembly required.

Simply set up the RCS5T with your main water supply line, and it will provide cleaner, fluoride-free water to all the water outlets in your home, including the shower.

The iSpring RO system is a comprehensive, 5-stage water purification device.

The first stage is a sediment pre-filter that removes all the particulate matter down to 5 microns.

The second stage is a granulated carbon filter that eliminates all the tastes, odor, and cloudiness. And the carbon block filter in the third stage removes residual chlorine before sending the water to the RO membrane.

RCS5T’s unique dual-flow reverse osmosis membrane is the fourth stage of the system. Here, all the stubborn fluoride particles are trapped. 

The water is forced out of the ultra-fine membrane, leaving behind fluoride molecules and all the leftover contaminants from the previous stages.

The fifth and the last filtration stage involves the post-carbon filter that also removes chlorine and improves the overall taste of the water.

Issues & Limitations

The only major problem with the iSpring RCS5T is that it comes without a water reservoir tank.

Although the 500 gallons per day output is sufficient for most households, the water flow rate changes with water quality and environmental temperature, so you might experience a pressure drop sometimes.



The iSpring RCS5T 5-stage filter is one of the most affordable and reliable fluoride water filters.

It removes up to 99% of all the contaminants in your water, including fluoride. A high water output and long filter lifespan really make it a good choice for whole-house fluoride filtration.


Best Under Sink Fluoride Water Filter

The Home Master TMAFC Filter also uses reverse osmosis to purify and enhance water quality. 

With its 7-stage process, it ensures pure and safe, fluoride-free drinking water. It is an under-sink water filter and comes with a separate faucet for pure water.

The TMAFC filter has a decent water output of 50 gallons per day and comes with a 3.2-gallon storage tank so that you don’t have to wait for clean water. It also remineralizes the water to restore its alkalinity.



Our Review

Apart from fluoride, the Home Master TMAFC also effectively removes up to 98% of contaminants and impurities from the water to make it safe enough for consumption.

This under-sink fluoride filter is NSF-certified. Home Master TMAFC Filter does not use any lead or BPA and meets all material safety and performance standards, making it increasingly fitting for use in areas with excessive water contamination.

The Home Master fluoride water filter uses wide tubes and large fittings to facilitate the flow of water. 

Compared to traditional  RO filtration systems, the design enhancements in the Home Master water filter allow the water to run twice as fast through its filter.

The TMAFC is a 7-stage fluoride filter. These include a sediment filter, a catalytic carbon filter, a 0.0001-micron reverse osmosis membrane, 2 coconut shell activated carbon filters, and 2 artesian remineralization filters.

While all other filters remove different contaminants to improve water quality, the RO membrane removes fluoride.

Unlike most RO filter systems, TMAFC does not contain loosely-placed filtration membranes. Instead, it utilizes an American-made Dow 0.0001 micron filter to achieve 98% water purification.

Issues & Limitations

The biggest shortcoming of the Home Master TMAFC is its big and bulky design. If your under-sink cabinet is small, you will have a hard time setting it up.

And despite the helpful instructions, its installation is a little difficult.



Home Master TMAFC Filter is a comprehensive water treatment system that not only removes toxic fluoride but it also mineralizes the water and improves its taste.

With this installed under your sink, you will have fresh and crisp water on demand.

Harmful Impact of Fluoride Toxicity in Drinking water

Fluoride is a naturally occurring mineral.

Commonly found in water, food, and soil, it is really good for dental hygiene. It strengthens teeth, averts tooth decay, and prevents cavities. 

That’s why most oral hygiene products, like toothpaste, mouthwashes, and floss, contain fluoride in certain capacities.

But it can do a lot of harm to the rest of your body if you ingest it. These harmful effects include:

Dental fluorosis

Dental fluorosis is the most commonly noted issue of fluoride consumption. It usually occurs in children and exhibits itself as white streaks on teeth.

Although this condition does not pose any significant health problems, it does make the teeth appear unsightly.

Skeletal Fluorosis

Skeletal fluorosis is a more severe condition than dental fluorosis. While the latter may not pose severe health complications, the former directly affects your bones and joints.

It happens when excess fluoride settles inside your bones and joints, causing them to harden. The condition makes it difficult to move around and increases the risk of fractures.


Hyperparathyroidism is a serious health condition where the thyroid gland starts to produce too much thyroxine hormone. 

When you have a high level of fluoride inside your body, it can damage the gland and trigger the gland to secrete hormones uncontrollably.

Too much thyroxine causes calcium depletion in your bones. As the calcium levels drop, your bones become weaker, and you risk breaking them even after a short fall.

Fluoride Poisoning

The most serious issue caused by excess fluoride consumption is fluoride poisoning.

It is characterized by nausea, abdominal pain, seizures, muscle spasms, and excess saliva. Fluoride poisoning can also cause intestinal blockage.

Although developing this condition from drinking water alone is extremely unlikely, you should take necessary measures if any chemical contamination is reported near your water source.

Cognitive issues

High fluoride concentration also has adverse effects on children’s mental growth. 

Just like lead and arsenic, fluoride is also categorized as a neurotoxin. It can cause small kids to develop cognitive issues as they grow up. It impairs their learning skills, slowing them down in the walk of life.

What Is a Fluoride Filter – And How Does It Work?

A fluoride filter is a water filtration device that removes high concentrations of fluoride from water.

As we mentioned earlier, fluoride is a stubborn water contaminant that is difficult to remove via boiling and traditional filtration methods.

For this reason, you need a good fluoride filter that can prevent fluoride particles from making their way to your drinking water.

A sure-fire way to remove fluoride from water is reverse osmosis.

RO fluoride water filters use an ultra-fine semi-permeable membrane to filter out up to 99% of total dissolved solids from water, including fluoride.

They are multi-stage systems that systematically remove different sized particles as the water passes through them and provide clean, better tasting, and safe water.

Another type of fluoride filter is a water distiller.

Water distillers use electricity to heat water at high temperatures to convert it into steam. 

As the water evaporates, it leaves behind all the good and bad things dissolved in it. The steam then cools down and collects as pure water in a separate container.

Lastly, different filtration media efficiently remove fluoride by absorbing it. You can find bone char carbon and activated alumina cartridges for this purpose.

Why Buy a Fluoride Filter Over Other Kinds?

Because fluoride is a stubborn and hard mineral to remove, traditional filtration methods are not effective at removing it. 

You have to resort to filtration methods that can actually reduce the amount of total dissolved solids (TDS) in water for effective fluoride removal.

Reverse osmosis and distillation are two processes that are highly apt at eliminating fluoride. You can also get a bone char carbon filter cartridge or an activated alumina filter bottle for this purpose.

Other filtration methods like sediment filtration and coconut shell carbon filtration have little or no effect on the fluoride concentration in your water.

What To Look for in a Fluoride Filter

water filters that remove fluoride

Even though many water filters list fluoride on the list of contaminants they can remove, you have to make sure it is not an empty claim before shelling out your hard-earned money.

And since fluoride filters come in various shapes and sizes, you have to be absolutely sure that the model you choose fits your needs.

Here are some things to look for in a fluoride filter.

Type of Filter

Out of all the water filters for fluoride removal discussed above, water distillers and reverse osmosis systems are the most readily available options.

Water distillers are mostly countertop units that supply small amounts of water at a time, which is enough for drinking purposes.

Meanwhile, RO systems are available in a more versatile range. You can find under-sink, countertop, and whole-house reverse osmosis filters.

The best type of filter for you depends on your personal needs. If the fluoride concentration is high in your water supply and you want to ensure that all your water is contaminant-free, then a whole-house filter is a better choice.

But if you want to purify your primary water outlet, then look into getting an under-sink or countertop filtration system.

Filter Lifespan

Not all fluoride water filters have the same service life.

Point-of-use fluoride filters have a 3 to 6-month lifespan, while point-of-entry systems can last for years.

If you are inclined towards a filter with a short lifespan because of a lower price point, consider whether making double the number of filter replacements might make it worthwhile in the long run.

Remember that filter changes are something you can’t put off; otherwise, the system will lose its effectiveness.


Fluoride filters are not cheap. While there are some affordable units, most high-quality reverse osmosis filters and water distillers are very expensive.

If you are wary of the high upfront cost, remember that the investment will pay itself off in the long run, given that you take good care of it.

This one-time purchase will save you from spending lots of money on bottled water by supplying you with similar quality water straight from your tap.

There are some cheaper systems, but they tend to become faulty or break down after some time. 

If you are not ready to make a significant investment just yet, it’s better to start small first. You can always switch to a bigger and better system once you are ready for it.

Removal of Other Contaminants

While fluoride removal might be your primary goal for purchasing a good fluoride water filter, it is always a good idea to look into the other contaminants the filter can remove.

It is best to test your water for possible contaminants and then choose a water filtration system that can eliminate the most contaminants from your drinking water.

If the chlorine content of your water is also high, you should look into getting an NSF-certified fluoride water filter model for chlorine removal.

On the other hand, microorganisms are the biggest issue with well water, so a fluoride filter with NSF certification for standard P231 is a good choice.

Installation of Fluoride Filters

The installation of fluoride filters depends on the kind of filter you go for.

A whole-house fluoride water filtration system is installed directly on the main water supply line so that it treats all the water that enters your house. 

All you have to do is shut the main water supply and open all the taps to drain leftover water. 

Then cut the pipe and install the system securely over it. Once done, turn on the water supply and flush all the taps to enjoy pure, great-tasting water.

Standalone, countertop RO systems and water distillers do not require any installation. You can simply set them on a countertop, fill them with water to purify and let them do their job.

But both under-sink fluoride filtration systems and countertop filtration systems that hook into your home’s water supply require proper installation. 

Both usually come with their own water outlet and reservoirs to store and deliver purified water on demand.

To install these systems, you first have to install the provided fitting on the cold water supply to your sink. Then, make a hole for the filtered water faucet and install it.

Lastly, connect the tubing from the fitting to the system and then to the filtered water faucet. Now every time you use that faucet, you will get clean, fluoride-free water.

Pros and Cons

Fluoride water filters undoubtedly bring many benefits to your household, but they also have some limitations that you should weigh in before finalizing your purchase.



Cleaning and Maintenance

water filters that remove fluoride

Regular cleaning and maintenance of your fluoride filter is the key to extending its life.

To clean a distiller, all you need is Sulfamic Acid or white vinegar. Pour a small quantity of either of these in the boiling chamber, swirl it around for 10 to 15 and let sit overnight. Empty the chamber and rinse a few times with clean water.

Meanwhile, maintaining an RO system mainly involves the periodic replacement of filter cartridges. 

All the different filtering stages have varying lifespans, so be sure to replace them all accordingly.

You should also clean and sanitize your RO fluoride water filter annually, preferably when the filter is being replaced.

To do so, first shut off the water supply to the system and drain it completely. Remove the previous filter cartridges.

Then, pour about 1 cup of hydrogen peroxide into stage one housing and turn on the water supply.

Let the system run at least through 2 cycles. Shut off the main valve again and install the new cartridges. Allow the tank to fill up and drain one last time.

Bear in mind that regardless of the type of fluoride filtration system, you should always check the user manual for information on proper cleaning and maintenance to prevent any mishaps.
