Fluoride is a mineral found naturally in water, soil, and foods. It can also be produced synthetically to be used in toothpaste and drinking water. Fluoride can have both positive and negative health effects, that’s why it’s important to keep track of your water source levels of minerals.
Testing your water and tracking the fluoride levels also helps children prevent tooth decay, and help you save money by not going for dental checks.
The negative effects of excess fluoride are:
- Skeletal fluorosis
- Dental fluorosis
- Thyroid problems
- Neurological problems
However, if it’s levels are optimal then it can have positive effects such as reduced tooth decay by 20 to 40 %, protection against cavities and saves you money by skipping dental appointments.
All those benefits can be achieve using a water filter which can help control the fluoride level from your water source. In this post, I’ve listed five best fluoride water filters that you can use at home with ease.

Best Fluoride Water Filters Reviews
1. EHM Ultra Premium Alkaline Water Pitcher
This water filter pitcher uses activated carbon technology, which is proven to be effective against fluoride. The device manufactures have developed a 6 stage filter that can remove heavy metals, chlorine and other types of contaminants. It can also change your water pH to a value of 10 but this varies on the quality of your household water.
Besides removing impurities the EHM Ultra also improves the quality of the water by adding magnesium, calcium, antioxidants and potassium minerals. And it provides an ORP between -100 and – 200 mv.
What is ORP?
Oxidation-reduction potential (ORP) is a measurement that shows the degree to which a substance can be oxidized or reducing another substance. It can be measured in millivolts(MV) using an ORP meter.
- A positive ORP means that a substance is an oxidizing agent, the higher it goes the more oxidizing it is.
- A negative ORP indicates that a substance is a reducing agent, a lower value reading means it’s more anti-oxidizing.
Many types of drinking water like tap or bottled have a positive ORP reading which means that they are oxidizing agents.
This handy water filter pitcher can produce Alkaline ionized water which is an anti-oxidizing agent, meaning that it is able to donate extra electrons in order to remove the negative effects of free radicals on your body.
It is a rigid device built using premium quality materials besides it goes through a strict quality checking ensuring that you get a fully functional fluoride water filter pitcher.

This water distiller offers a solid and effective choice in terms of fluoride removal, it’s also very easy to use just add water then press the start button. Though the process of distillation you can remove most contaminants, bacteria, and toxins.
A distiller basically emulates nature own’s process of water purification process that why it is so effective.
It works by heating up the water to 212 degrees, then steam starts to raises into the cooling chamber, leaving behind contaminants including fluoride, bacteria, and toxins. The cooling chamber contains stainless steel coils which then cool down the steam and recondenses into pure water.
And to be sure that no contaminants have infiltrated in the steam, it goes through an activated carbon filter. After the process is finished it’s gonna shut down automatically.
Inside the collection bottle enters only clean water with improved taste. Since our bodies contain 70% water staying hydrated is very important.
So what are the benefits of drinking purified water?
- Improved health
- Thinking cleared
- Feeling better
- More energy thought the day
It’s also environment-friendly since it reduces your carbon footprint and reduces the usage of plastic bottles. This water distiller is built from high quality 304 stainless steel, so durability won’t be a problem. The manufactures have a 27 years history of building water distiller and they test every product by hand. Meaning that every unit has an ensured top quality.
However, the downside is that it takes a while for the water to purify approximately 5.5 hours for 1 gallon of water. This is the case with most consumer-grade countertop water filters.
The megahome countertop water distiller is an excellent water filter that removes fluoride and can get rid of other impurities and bacteria.
3. AMOYEE Faucet Mount Filter
The Amoyee is a fluoride filter which requires to be mounted on your faucet, it uses the ultrafiltration membrane technology. It’s a very accurate device since it can filter 0.01 microns. The Amoyee can also remove lead, chlorine and other impurities found in tap water.
This water filter contrary to most available on the market is quite quick, you won’t have to wait hours for fluoride-free water. It can filter 10 cups 7 oz per cup per minute.
It’s also has a long life durability dues do its build quality, this device is built from food-grade 304 stainless steel. Here are some benefits of this material:
- No cracks
- Zero rust
- Corrosion resistance
- Improved durability and look
Each faucet can provide 600 gallons of clean water, which is equal to approximately 6 months. That is two times more than the average water filter. With one amoyee fluoride filter, you can replace around 1500 standard 16.9-ounce plastic water bottles.
Also what makes this filter convenient to use is that it’s easy to install, it works with all standard faucets except the pull-out types. You can also switch between modes, filtered and unfiltered water if you need too.
The cartridges can be replaced with ease, are environment-friendly and more economical. One filter cartridge typically lasts 6 months but it is recommended to pay attention to the water quality since it may need replacement earlier.
Before starting to use the device remember to turn on the purification mode on for 3-5 seconds every day.
One thing to keep in mind is that this water filter is made for municipal tap water if other water source types are used the water quality and the filter may be affected. Also, it is advised to not filter hot water above 113°F/45°C since again the filter may get damaged.
Without a doubt, this is also a strong choice if you don’t like waiting long times for pure water with no fluoride. Also, it’s very convenient to use since all you have to do is mount it to your faucet.
4. Aquatic Life RO Buddie Reverse Osmosis
The aquatic life takes advantage of reverse osmosis which is one of the best water filters for fluoride available today.
Though the process of reverse osmosis minerals like fluoride, lead, arsenic and other suspended and dissolved solids like bacteria are removed.
This particular device has multiple versions you can buy it’s pretty easy to install and it doesn’t take much space. It has an affordable 3 stage filter which is a very good value and can be upgraded in time to a 4 stage if you need to. The more expensive 4 stage offers better water filtration with close to 0% TDS (total dissolved solids).
If you wish to upgrade you’ll need to buy the De-ionization color charging mixed bed resin cartridge. The included anion and cation resins inside the de-ionization cartridge remove the remaining total dissolved solids. This cartridge can be refilled and has a clear housing so you’ll know when you need to do so.
The changing color cartridge goes from blue to amber when the media is depleted. Each cartridge comes with two clips that allow attaching to the front of the membrane housing.
All systems use thin-film composite membranes in combination with sediment and carbon cartridges. These filters ensure the removal of harmful substances like dissolved solids, heavy metal ions and particulate mater from municipal water sources.
Keeping track of when the carbon cardigan needs replacement is important because any chlorine not absorbed by a depleted cartridge is going to damage the membrane.
It can filter 1500 gallons of water only if your chlorine level is 1 ppm. The amount of filtered water goes down with the increase of ppm, with two ppm you get 750 gallons with three 500 and it keeps going on.
Also, something important to know is that the 1500 gallon threshold is the total water that passes through the water filter. The rejection rate for this reverse osmosis system is 1:4.5. This means that for every 1 gallon of filtered water produced it rejects 4.5 gallons, leading to a total of 5.5 gallons of water passed through the device.
If your water source has a 1ppm level of chlorine you can produce around 360 gallons of water without fluoride, before needing to change the carbon cartridge. With 2 ppm you can make around 180 gallons and with 3 about 120.
By changing filters on time not only you assure that the water filter produces only clean water but also you’ll extend the membrane life span. It will last 2 years if the cartridges are changed when required.
In general, you should know that the quality of water affects the longevity of cartridges.

Also, you can check out other studies that have been conducted on this water filter here.
And if you worry about the water pitcher breaking, aqua gear offers life guarantee and same-day support. If your water filers ever stop working you’ll get it replaced without any charge.
Overall this is also a good option for fluoride removal, but it also depends heavily on your water source. And what kind of impurities you need to remove, this pitcher can remove some type of contaminants that other products don’t. Keep in mind that pitchers usually take a lot of time to produce filtered water.
But if you find yourself needing to remove specific minerals, this is one of the best water filter pitcher that removes fluoride plus other types of contaminants.
How do water filters work?
The water filters available today use two types of defluorination techniques which are the membrane and absorption methods.
The membrane techniques use the nanofiltration, ultrafiltration and reverse-osmosis methods and the absorption one uses activated carbon, alumina and the likes.
First, let’s discuss the membrane techniques since they tend to be more effective.
The reverse osmosis (RO) is one of the most effective technologies today used for water purification.
It can effectively remove fluoride, arsenic, lead and other contaminants from water. And also different kinds of suspended and dissolved species from the water like bacteria, it is used both in the production of potable water and industrial processes.
RO is a process where water gets de-ionized or demineralized by pushing it under pressure through a semi-permeable reverse osmosis membrane.
To fully understand the whole reverse osmosis process, first, you need to know how osmosis occurs.
Osmosis happens naturally and is amongst the most important processes that occur in nature.
So what it really does?
It is a process where a weaker saline solution tends to transfer to a stronger saline solution. Some examples would be when our kidneys absorb water from our blood or when plant roots extract water from the soil. So we could say that reverse osmosis is osmosis but reversed.
Osmosis happens naturally without no source of energy needed whereas reverse osmosis will require to apply energy to the more saline solution.
The RO membrane is semi-permeable, the water molecules have a “free pass” but that’s no the case for the most dissolved organics, salts, pyroxene, and bacteria.
So in order to desalinate the water allowing only the pure water without contaminants, it needs to be pushed through the reverse osmosis membrane. To successfully do that it requires to apply a stronger pressure than the naturally occurring one.
In the following diagram, you can see how the process of reverse osmosis works. When pressure is applied to the water with contaminants, the water molecules are forced through the semi-permeable membrane. The filtered water leaves behind around 95% of dissolved salts.
One key factor to know is that unless like conventional filters where the contaminants are collected in the filter media. The reverse osmosis system has cross filtration, which allows the solution to pass through the filter or cross it. It has two outlets the clean water goes one way and the contaminated water the other way.
It helps to protect against contaminants build up as well. The cross filtration process allows water to remove contaminants build-up and keep the membrane area clean.
Ultrafiltration (UF) is a process alike reverse osmosis, it’s using hydrostatic pressure to push water through a semi-permeable membrane. The use of ultrafiltration is a fairly new concept for water treatment, though it is commonly used for other industries.
UF acts like a barrier to bacteria, suspended solids, endotoxins, and viruses. It can produce top-grade quality water with a very low amount of slit density and high purity.
Ultrafiltration is not different from reverse osmosis, nanofiltration or microfiltration, the difference is in terms of the size of impurities it can restrict.
And when combined with other purification methods in a complete water filtration system it can effectively remove pyrogens, bacteria, and macromolecules bigger than the pore size of the membrane.
Several factors can affect the ultrafiltration process which are:
- proprieties of the membrane
- the material of which the membrane is made out of
- designing of the membrane module
- engineering parameters of the process
However, the most important factors in terms of performance are rejection and flux. Flux is other words is the volume of permeate per unit time per unit membrane surface. A higher flux will result in lower operating and capital costs. The rejection is a way to measure the membrane’s separating capabilities.
Membranes are made from a variety of over 150 different inorganic materials, or polymers however, only a dozen are commercially available. The most common inorganic materials are alumina, titania, and zirconia. And the most used polymers are regenerated cellulose, difluoride and polysulfone.
A UF membrane has a special skin which contains pores of the exact size and determines the separation aspect of the membrane.
Inorganic membranes have a wide range of applications in the industries of food processing, waste treatment, and biotechnology applications and water filters.
Also recently UF has been recognized as a potent pre-treatment for reverse osmosis. A system designed with ultrafiltration treatment prior to reverse osmosis is called IMS (Integrated Membrane System).
An IMS is a must for industries that require raw quality water or extensive conventional pre-treatment.
UF is also a preferred choice to remove water-borne pathogens in preparation for drinking water. Studies show that ultrafiltration could produce consistently great quality of water independent of the raw quality fluctuations.
Benefits of ultrafiltration:
- Constant quality of treated water without bacteria
- It works “as-is“, no need for any maintenance
- Friendly for the environment
The activated alumina is the solid form of aluminum oxide, it is also porous which means that liquids or air can pass through it. The alumina has many industrial usages including the making of precious gems like ruby and sapphire. It is also used for water filters available today.
Regarding its many usages, the water defluorination is also what is mostly used for. It acts as a filtering medium because of its many advantages, those being the ease of use, cost, possible re-use, absorption capacity, the possibility of regeneration and the number of useful cycles.
The activated alumina is one of the most effective ways to remove fluoride used today. Fluoride is heavily attracted to alumina which has a big surface area with a large array of tunnel-like pores.
When used correctly in a system it can remove up to 98% fluoride from water.
The activated alumina also has the power to remove many contaminants including:
How activated alumina works?
There are special devices that contain a packed bed of activated alumina granules. As the water passed through the device, contaminants like fluoride get absorbed on the activated alumina granules. The scientists have also found it to be an efficient treatment for water with a high sulfate concentration and total dissolved solids levels.
Its effectiveness is based on various factors including the device design, the contact time, characteristics of alumina, pH and fluoride concentration. The pH level is one of the most important factors, usually, the water pH should be less than 8.5 For the fluoride removal the optimal level is 5 and 6 and for arsenic 7.
The pretreatment of water may be necessary in order to achieve a successful defluorination process. If the untreated water includes suspended solids a pretreatment using a 5-micron cartridge sediment filter is needed to avoid the clogging of the alumina bed.
Also if manganese and iron are present their concentration should be below 0.05 mg/l for manganese and 0.3 mg/l for iron.
Does activated alumina add aluminum to drinking water?
A group of scientists has been asked to investigate this subject, after so much online controversy. They evaluated the removal of fluorine from mineral water using filtering through activated alumina bed.
After they did the treatment, an increase in concentrations has been observed, for aluminum from 18 up to 86 microg/l. But these results were not the same for every type of water, in most cases, the results were not observed at all.
The chance of activated alumina “leaving behind“ aluminum depends on the water ph and the manufacturing process for alumina. Considering the data provided by researchers, improving the ph levels and selecting an appropriate medium will ensure that activated alumina will not exceed the safe levels.
The recommended release of aluminum ions from the activated alumina filtering process should not exceed 200 microg/l.
It was demonstrated that this process is safe and will not harm the drinking water quality.
Activated carbon (AC) is a very effective way to remove fluoride from tap water, also bad taste and odor. It may also be referred to as a charcoal filter.
It is very effective in absorbing fluoride and removing other contaminants due to its massive surface area. AC contains tiny pieces of carbon in block or granular form which have been treated to be very porous.
How does it work?
When the water starts to flow through the filter the impurities stick to the carbon leaving the output with clean water. However, it’s effectiveness is affected by the temperature and the flow of the water.
It is recommended the usage of smaller active carbon filters with cold water at low pressure.
There are two main types of activated carbon used in water treatment, powdered activated carbon (PAC) and granular activated carbon (GAC).
GAC is fabricated from high carbon materials like coal, lignite, and wood, the main difference between PAC and GAC is particle size. Activated carbon can have different capabilities based on the particle size they can remove. You can get the best efficiency out of the coconut shell activated carbon.
Also, an important factor is the size of particles that the filter will allow passing through, hence this will provide a second barrier. Because GAC material is porous it has no limits whatsoever. However, activated carbon in the shape of carbon blocks is limited to a pore size between 0.5 to 10 micron.
However, the smallest sizes have a problem with the water flow, it ends up being reduced as even the particles struggle to pass through.
How effective is activated carbon at removing fluoride?
Contrary to what you might have read online, activated carbon can remove fluoride and there are several studies that prove it.
A study on which fluoride was tested on six different types of drinking water shows that AC can effectively decrease the amount of fluoride from water. The removal of fluoride decrease as the pH level increases, the researchers found that 6.71 was the optimal pH for tests.
On the other hand, the removal of fluoride increases with the amount of absorbent.
After using all the optimal parameters the removal of fluoride was successful for all six types of drinking water. All the results were good and this proves that fluoride can be removed from water using activated carbon.
The devices available today on market are optimal to use for fluoride removal, manufacturers are making sure that the filters found in those devices are used at required parameters.
What is a water distiller?
It is a water filter that transforms water into steam in order to remove fluoride, lead viruses and other contaminants. You can think of a water distiller like a device that imitates the earth’s natural purification process, resulting in high purity drinkable water.
It can get rid of even the most difficult contaminants like dissolved solids and salts, through the process of condensation and boiling.
Earth purifies the water every day probably even now as you read this.
How you may ask yourself?
It starts with naturally occurring heat from the sun which evaporates water from lakes, ponds, and oceans and turns it into water vapors. Then these vapors start to rise and begin to cool, then these “chilled“ vapors condense and form clouds. Then that water is returned back to earth as rain or snow.
This cycle is basically recycling and purifying Earth’s water, the heat of the sun evaporates water it also removes any contaminants and minerals. Distillation emulates this process very well that why it’s such a good device for fluoride removal and other impurities.
So how does a water distiller works?
First, you’ll need to add water into the boiling chamber which is equipped with a heating element that will increase the temperature of the water to a rolling boil.
Steam is produced as the water temperature is higher, on the top of the boiling chamber, there are some vents. The steam enters through those vents and goes in the condenser, leaving behind the contaminants including fluoride and bacteria. Inside the condenser, the steam will be transformed back into liquid form.
At the top of the water, the distiller can be found a high powered fan which cools down the vapor into water droplets. Lastly, the droplets travel through the condenser tube into an activated carbon filter. This last step gets rid of any contaminants that might have infiltrated into the steam.
However, all this process can take a long time approximately between 3 and 6 hours, the consumer-grade devices work slowly. Only the industrial ones can produce fluoride-free water more quickly.
These are the best water filters to remove fluoride, you can’t go wrong with any of these five listed above. Just pick the one that fits your needs the best. In general pitchers and distillers are slower than faucets, but they can be more effective at removing contaminants. Also, pitchers can remove some minerals which faucets can’t.
