Although it’s thought that fluoridation of water can be beneficial for strengthening our teeth and bones, it can also damage our health. The same can be said of chlorine; although it disinfects water from harmful viruses, bacteria and cysts, it can also be harmful to consume when the concentration is too high.

Municipal water supplies in the US contain both of these elements. Like many other Americans, you may want to remove them from your drinking water. Below you’ll find our list of product reviews from water filters that claim to do just that, as well as other useful information about fluoride, chlorine and filtering your water supply!

So, here are the best water filters to remove fluoride and chlorine.

the best water filter for chlorine and fluoride

1. Best for Whole House: Crystal Quest Fluoride and Chlorine Water Filter

For whole house use, the Crystal Quest is the best water filter to remove fluoride and chlorine in 2023. When used properly, fluoride content can be reduced to up to 90-95%, and chlorine up to 99%!

This water filter is available in two sizes; the smaller of which suits homes that contain up to 3 bathrooms, and the bigger system suits homes for 4 or more baths.

Each size comes equipped with a head valve, which is programmable and provides automatic backwashing which lets the fluoride filter media increase its life to up to 1 million gallons of filtered water! This means you won’t need to replace the filter media for several years each time.

  • Large particles such as dirt, silt and sand are prevented from sticking in the tank thanks to the 5-micron sediment pre-filter (20”) that traps them.
  • Makes use of a charcoal based mineral tank that contains granular activated fluoride filter media. Maximum fluoride removal is ensured by the combination of chemical reactions and absorption.
    • Mercury, arsenic, and lead are also removed.
    • The whole house filter is specifically designed to be effective with municipal water that contains inorganic fluoride.
    • Works with many different pH levels.
  • Bacteria are prevented from growing inside the tank thanks to copper-zinc alloy.
  • Taste of the drinking water is further improved by the 5-micron coconut-shell carbon block post-filter (20”) which eliminates pollutants and chemicals like chlorine.
  • Two sizes to choose from:
    • The smaller model has filter media of 1.5 cubic feet, and at a flow rate of 9-11 gallons per minute it will last for 750,000 gallons.
    • The larger model has filter media of 2.0 cubic feet, and its 10-13 gpm flow rate allows it to last for as much as 1,000,000 gallons!
  • Easy installation and programming thanks to solid instructions.
  • There’s a choice between steel or fiberglass casing to provide durability.
  • Life of sediment pre-filter is 2 years, while the carbon post-filter has a life of 12-18 months. The system should work for an estimated 8-10 years before bone char requires replacement (if used by a family of four).
  • Overall average cost annually: $115-140, with the larger system obviously costing more.
  • Warranty of one year covered by the manufacturer.


  • Quite a steep price tag at the beginning.

Best for

The Crystal Quest is best for people who want a highly effective POE filter system for removing chlorine and fluoride.

2. Whole House Water Filter System Alternative: USWS Bodyguard + Fluoride Combo

If you want a solid alternative to the Crystal Quest, then this whole house filter combo by US Water Systems is the way to go. It entails the Bodyguard Whole House Chemical Removal Filter plus the Fluoride Removal Filter.

The combo can remove chlorine by up to 99% and fluoride up to 98%, as well as other harmful water contaminants such as chloramine, lead, and chemicals like pesticides.

The Bodyguard has a robust 5-step filtration process, most importantly a 5-micron sediment pre-filter cartridge followed by KDF-55, coconut shell granular activated carbon, and catalytic carbon filter media. The fluoride filter is based on bone char.

All in all, you get clean, fluoride-free, and great-tasting water everywhere around your home. This not only protects your plumbing and appliances, it also benefits your hair and skin – think chemical-free showers.

Our Rating


  • Improves the taste and smell of water thanks to Bodyguard’s 5-step filtration process:
    • Step 1: 5-micron Magna pre-filter is made in the US, and traps large particles, so they don’t stick in the tank.
    • Step 2: Washed quartz gravel provides a great substrate for even upflow filtration.
    • Step 3: KDF-55 redox filter media is bacteriostatic, preventing the growth of bacteria and removing chlorine by up to 80%.
    • Step 4: Coconut shell granular activated carbon further removes chlorine and other chemicals.
    • Step 5: Catalytic carbon focuses on removing chloramine.
  • Fluoride filter uses bone char + quartz gravel. This provides for most effective fluoride filtration at the point of entry.
  • Both tanks use Vortech technology which prolongs contact time between water and filter media for improved contaminant reduction rates.
  • Three sizes to choose from:
    • The BGS-10-FL has a continuous flow rate of 8 gpm (gallons per minute), and a maximum flow rate of 10 gpm. Ideal for up to 3 bathrooms.
    • The BGS-15-FL provides up to 15 gpm suited for 4-5 baths.
    • The BGS-20-FL is rated at a continuous water flow of 16 gpm, and a maximum flow rate of 20 gpm. It’s designed for very large homes with 6+ bathrooms.
  • Straightforward installation process with easy-to-follow instructions.
    • Bypass valve included.
  • One pre-filter cartridge lasts 6-12 months (~$50-90 annual replacement cost). The filter media contained in the Bodyguard tank lasts a full 1,000,000 gallons or 5 years. The fluoride removal media is good for 400,000 gallons or 3 years.
    • Low maintenance!
  • You get lifetime warranties on the tanks + heads. The filter media is warranted for 3-5 years.


  • The whole house combo is rather pricey.
  • The media doesn’t come pre-installed, and improper installation can lead to filtration issues.
  • USWS states filter media needs to be changed every 3-5 years, which is shorter than the 8 years of the Crystal Quest and other similar systems.

Best for

The USWS Bodyguard combo is our second top pick for removing chlorine and fluoride from water at the point of entry.

3. Best for Ease of Use: Clearly Filtered Pitcher

For point-of-use applications, the Clearly Filtered pitcher is far and away the best water filter for chlorine and fluoride in 2023. This is mainly because it eliminates more waterborne pollutants than all other water pitcher filters! If clean, pure drinking water is a priority for you, then so should the Clearly Filtered!

With a reduction in both fluoride and chlorine of at least 99.5%, it’s a bargain for what you pay.

After setting up the pitcher and using it for a while we really liked this pitcher (…). It tastes really good, it pours easily, it was easy to set up, and I like how it looks on the counter. So it gets 5 stars in my book.

Alexa Gibbons – BOS Video Content Creator



  • This water pitcher filter is the only one that is tested against a total of five NSF standards (42, 53, 401, 244 and P473) to excellent results. Over 365 contaminants are targeted, including chlorine and fluoride, chloramine (99.9%), arsenic (99.6%), lead (99.5%), cysts and bacteria (99.9%), over 24 pharmaceuticals (99.9%), PFAS (99.6%), over 100 VOCs (most to 99.9%), many herbicides (93.2 to 99.9%), chromium-6 (96.9%) and pesticides (99.9%).
    • However, all healthy, beneficial minerals remain in your water supply! These can add to regular daily intake.
  • It makes use of Affinity Filtration Technology, which combines granular activated carbon with other important filtering material.
  • The pitcher filter only takes about 2 minutes to assemble – putting it together is simple (and we can attest to this!)
  • Has the capacity to hold 10 glasses of water maximum. If refilled regularly, this is plenty for an entire family.
  • Both the filters and the pitcher itself are completely free of BPA thanks to being made of Tritan plastic, which also does not leach chemicals. They are also produced in the US!
  • A filter cartridge lasts for about a hundred gallons of filtered water, which on average works out to about 4 months and helps to keep all maintenance to the absolute minimum. They do cost $50 per cartridge, but it’ll be cheaper and cost effective if you subscribe and purchase in bulk!
  • A 30-day refund guarantee ensures you’ll get your money back in full if you are not happy!
  • Top grade customer support and a lifetime warranty on the pitcher are the icing on the cake.


  • Clearly Filtered’s water pitcher filter is not only more expensive, but also more difficult to maintain than other pitcher filters.
  • While we haven’t had any problems ourselves, some customers report that their filter pitchers don’t have as long a life as they are advertised to have, as well as slow filtration speed.
    • Slower filtration speed can actually be a good thing, as a longer contact period between filter media and water allows for more in depth filtering.
    • Clearly Filtered will also replace unsatisfactory water filters for free.

Best for

The Clearly Filtered pitcher is best for people who want to remove fluoride and chlorine from their drinking water.

4. Best for RO Water Purification: AquaTru Countertop System

Even the smallest of POU RO systems are highly effective at fluoride removal in tap water supplies. Certain systems are even certified to remove over 93% of fluoride!

It’s our opinion that the AquaTru is the best performing reverse osmosis fluoride filtration system on the market. It’s NSF-certified (standards 53, 58, 42 and 401 and protocol P473) which guarantees dozens of pollutants will be eradicated from your water supply. The 93.5% reduction rate of fluoride and 96.6% for chlorine is a big selling point for the AquaTru.

However, an even bigger selling point is how the AquaTru system doesn’t even need to be permanently installed. As long as it’s placed on a countertop and plugged into a power supply, it’s ready to go! This convenient feature makes it ideal for those who rent, or who are even just visiting a home with no water filter. Maintenance of this system is also simple as can be, and with an affordable price, the AquaTru RO system basically sells itself.

The 3-part filtration system is quite impressive. It really removes everything out of the water. As far as water filtration systems go this will be a very high quality option for you. (…) Overall my review of this system is going to be a 4.5 out of 5.

Alexa Gibbons – BOS Video Content Creator



  • AquaTru RO countertop filter system is NSF certified. Its 5 certifications ensure that your water is fresh, clean, and ready for cooking and drinking! Over 80 pollutants are eliminated, including chlorine (96.6%), fluoride (93.5%), PFAS (97.5%), chromium-6 (97.2%), lead (99.1%), pharmaceutical drugs, pesticides, VOCs, and cysts (99.99%).
  • A filtration system of 4 stages guarantees this:
    • Stages 1 & 2 involve a mixture of activated carbon filtering and a sediment pre filter. This will filter out chemicals and large particles that would otherwise cause the system to clog.
    • In Stage 3, the RO membrane then removes the contaminating elements in the list above, and also more pollutants.
    • Stage four utilizes carbon filtration for even more chemical removal and better water taste.
  • 1 gallon of purified water is produced every ten to fifteen minutes due to the speedy filtration of the water pump that is built in!
    • Wastewater is also reduced thanks to high water pressure. About 80% of water is recovered, and 20% of all input water makes its way down your drain. (RO water filter systems that do not make use of pumps will waste up to three to five gallons of water to every gallon that is filtered!)
  • No plumbing or drilling is required when setting up the system. It takes ten minutes tops.
  • Its design saves space.
  • Simple to operate! The tank is filled with water and then installed back into the system. The reverse osmosis water gathers in the storage tank at the front, while the rejected water will be collected in the second tank, whereafter it can easily be disposed of.
    • Dispensing is carried out by a button that is easy to push.
  • The system’s plastic is free from BPS and BPA.
  • The filters have a life anywhere between six months and two years. Replacement can be conducted annually or bi-annually and can be conducted tool-free, and only takes several minutes! You’ll be reminded to install new filters via front panel lights.
  • The estimated cost is $100 – $120 annually, which is affordable for the system you get.
  • There is a one year manufacturer warranty.


  • A small number of customers had leak problems. Some even claimed that their RO system ceased working altogether.

Best for

The AquaTru is best for people looking for an RO system. It’s installation-free, compact, highly effective, and fast.

5. Best for Under Your Sink: Clearly Filtered 3-Stage

This Clearly Filtered unit is our number one fluoride filtration under sink system on the market in 2023. As well as the removal of 90.7% fluoride, it also provides the elimination of 98.6% of chlorine and over 230 other contaminants! This has been guaranteed by EPA-approved labs and testing that met important NSF standards.

To summarize, no other under sink system will do a better job at filtering fluoride, chlorine and general contamination from your water than the Clearly Filtered 3-Stage.

I’m going to give this a 5-star because I think that this it is the nicest product you can get for under-the-sink filter. I can’t believe how much different it made my tap water taste coming out of the faucet. (…) on top of that it was super easy to install and I could do it myself.

Alexa Gibbons – BOS Video Content Creator



  • Produced in the USA.
  • System is tested against NSF standards 42, 53 & 401. It traps and filters out lead (99.9%), chlorine (98.6%), chloramine (95.3%), hexavalent chromium (99.4%), PFA (99.9%), arsenic (94.3%), SVOCs (99.9%) & over 100 volatile organic compounds and other pollutants.
  • It does all this while retaining all beneficial and healthy minerals.
  • 3 filtering stages: Stage 1 involves coconut shell GAC. Stages 2 & 3 are a blend of proprietary media (a.k.a. Affinity Filtration Technology).
  • Installation is DIY, takes 15 minutes maximum and doesn’t need to be permanent, which is ideal for people renting and anyone looking to save some money!
    • All necessary hardware will be included.
  • On average, filters have a life of 365 days and are easily replaced in a matter of seconds. No tools are required, neither is the need for shutting off your water supply.
  • Hoses are stainless steel and are utilized for durability.
  • A lifetime guarantee is provided for the entire system.
  • There’s a thirty-day money back guarantee to receive a refund, if you aren’t satisfied with the product!


  • Water pressure is reduced by around 15-25% by the filtration system.
  • It’s a bit more expensive than other water filters, as are its replacement filters.
    • However, for the performance you get and the longevity of the filters, we believe it’s worth it.
    • When you subscribe, you’ll receive filters on a regular basis whilst saving 10% overall, as well as free shipping.

Best for

The Clearly Filtered 3-Stage is best if you prefer an under sink water filter. The system is highly effective at removing both chlorine and fluoride.

6. Best for Showering: Propur ProMax Shower Filter

Unfortunately, there does not yet exist a type of shower head that can effectively filter out and remove both chlorine and fluoride – some companies believe they have shower filters that reduce fluoride and chlorine, but they haven’t been found to be effective.

The next best thing that we found would be the Propur ProMax Shower Filter. With a chlorine reduction rate of 57.1% and fluoride reduction rate of 48.2%, this is the shower filter we recommend you use if you want to reduce these elements in your shower water.

Side note: If it’s within your budget, nothing is better than whole house filter systems to remove fluoride and chlorine from your water. Point-of-entry models treat all water in your home supply, including shower water. This leads to more thorough water filtration, such as the Crystal Quest filter, which can remove up to 90-95% of fluoride.

However, if you’re interested in Propur ProMax, its specifications are as follows:

  • Utilizes four proprietary filter layers.
  • NSF tested (standards 42, 53 & protocols P231 & P473) to remove over 200 contaminating elements in your water, thus saving you from any detrimental health issues. The most reliable testing we have witnessed being carried out via a shower filter head.
    • Chloramine (71.0%), chlorine (57.1%), VOCs (around 90%), fluoride (48.2%), mercury (79.2%), lead (61.1%), arsenic (28.0%), pesticides (50 – 60%), chromium (28.8%), semi-volatile compounds (70 to 80%), nitrates (23.6%). nitrites (82.8%).
    • While the results aren’t outstanding, they are better than other shower head filters.
  • Flow rate of 2 gpm allows for adequate pressure.
  • Includes a massaging head feature with five settings for spray.
  • A choice of three finishes: Brushed nickel, antique bronze or chrome.
    • Chrome and brushed nickel finishes also include a wand that is handheld.
  • Maintenance and installation is simple and won’t take up a lot of time.
  • Fits regular half pipe threads.
  • Each filter will last for six months. Each cartridge costs $42.
  • Plastic is free from BPA.
  • A year limited warranty and a 30-day guarantee.


  • Can be quite expensive considering the less than perfect results.

7. Best for On the Go: Clearly Filtered Bottle

The best fluoride and chlorine filter bottle (according to us) is another product from Clearly Filtered. There is a choice of 3 models; a stainless steel insulated filtered bottle, a Tritan plastic filter bottle, and a bottle constructed from glass.

While the materials differ, each bottle uses identical filter cartridges to remove practically the same number of contaminants that the CF water pitcher removes (which is reviewed above). Therefore, we can say with certainty that the water filtration is thorough and in-depth, more so than any other filter bottle we are aware of. With a fluoride and chlorine reduction rate of 99.5%, it’s easy to see why many customers are satisfied with their purchase.

  • Safe, healthy and fresh tasting water.
  • The quality is very high.
  • Affinity filtration by Clearly Filtered will filter out over 220 water contaminants. 99.5% fluoride and chlorine, 99.9% lead, 99.9% pharmaceuticals, 99.9% herbicides, 99.9% VOCs, semi-volatile compounds and pesticides.
    • Tested by EPA-accredited laboratories for NSF standards 42, 53, & 401.
  • Straightforward use. Fill the bottle, then suck the water out via the mouthpiece attached to its filter straw. The steel bottle has double-wall insulation, allowing for a maximum of 24 hours cooling.
  • Each filter lasts for 6 months or 25 filtered gallons.
    • This equates to 160 refills for the glass and steel filtered bottles, and the plastic just over 130 refills.
  • A choice of a range of colors!
  • Every material is free from BPS, BPA and phthalate, meaning nothing seeps into your drinking water.
  • Constructed in the USA.
  • 30-day refund guarantee as well as lifetime warranty coverage!


  • Strong suction is required to get adequate water (think drinking thick milkshakes).
    • The filters will end up less restrictive.
  • The bottle can leak if its silicone lid ring isn’t in the correct position.

The Clearly Filtered water filter bottle is best if you want clean water while you are outside the house.

8. Best for Home & Outdoor Use: Big Berkey Gravity Water Filter

Berkey water systems are effective gravity filters. As countertop units designed to be portable, they’re straightforward to install, simple to use, almost maintenance free, and highly effective at taking out a plethora of contaminating elements to allow for high-quality drinking water. 99.9% of fluoride and chlorine are removed when used in conjunction with the PF-2 fluoride filter.

It’s worth noting there are no differences between various Berkey filters other than their size, on which water capacity and filtration speed are determined. Outside of this, they use the same filtration elements which allow them to achieve equal water purity levels. The Big Berkey system is our favorite; it’s ideal for smaller families (around four people) and also isn’t very bulky, so it fits in the majority of kitchens and doesn’t take up too much space.

  • Produces fresh-tasting water.
  • Accredited laboratories have tested and certified that Berkey filters remove fluoride, chlorine, chloramine, bacteria, cysts, viruses, lead and other heavy metals, THMs, VOCs, Ibuprofen, pesticides, Bisphenol A, sediment, tastes and smells, and many more contaminants. NSF standards: 42 & 53.
    • Fluoride reduction is effective to a maximum of a thousand gallons.
    • Optional and additional PF-2 filters.
    • Healthy minerals are retained in the drinking water.
  • The filters use gravity to work. No external pressure or power is required. This makes them useful for emergency use or power cuts.
  • Practically all water can be used as the feed source.
  • Filter cartridges last a long time, making them cost effective.
  • Food-grade 304 steel tanks, meaning they have durability and also look quite good!
  • The casket is made of rubber and will protect your countertop from any scratches.
  • Ten minutes maximum to assemble.


  • Fluoride replacement filters have a significant cost.
  • There is a risk of overfilling, as if the lower tank is filled up, filtration doesn’t stop.
  • The upper chamber has to be lifted in order to check the amount of filtered water that remains.
  • Plastic spigot leaked for some customers.
  • Frequent re-priming of the filter is required.
  • Negative pressure may cause the flow from the spigot to be slow.

Best for

The Big Berkey is best for home and outdoor use. It’s one of the most effective at removing chlorine as well as fluoride.

9. Best for Inline & Refrigerators: CF Universal

The best fridge/inline water filter that removes chlorine and fluoride in 2023 would be the Clearly Filtered Universal, mainly because it’s the one and only inline unit properly tested to remove fluoride. The result is an effective filtration process that removes an average of 90.7% of fluoride and 98.6% chlorine.

Also helpful: The CF Universal is an inline filter, meaning it’s compatible with every appliance, including refrigerators. Once installed, any filter that came with your refrigerator doesn’t need to be used anymore. This can possibly be taken out, depending on the model.

Buying Guide: How We Picked the Best Water Filters to Remove Fluoride and Chlorine

The following are things worth considering before you go out searching for the best water filter to remove chlorine and fluoride. These are also the very same criteria we focused on when picking our top products for this guide.

Testing Your Water Quality

First things first – you have to test your water supply before you buy and install a water filter! Only by testing your water will you know its specific conditions in regards to chlorine and fluoride levels, and whatever other criteria it may meet with the filter you intend to purchase.

Water Testing Report

Filter Types

Overall, there are three primary methods of water purification that are successful at removing both chlorine and fluoride. While most filtration systems remove chlorine, not all of them can remove fluoride effectively, so it’s important to keep these in mind when choosing a water filter to buy.

These methods are:

  • Reverse osmosis
  • Distillation
  • Bone char

The filtration/purification method is more important than the kind of filter model (e.g. countertop or under sink) when it comes to removing chlorine and fluoride from your water supply.

With that said, specific types of filters are more effective than some regarding chlorine and fluoride filtration. These are:

  • Whole house filters
  • Water filter pitchers
  • Under sink and countertop systems
  • Water distillers
  • Gravity units
  • Filter bottles

NSF/ANSI Certifications

NSF & ANSI certifications guarantee that your chosen water filter will deliver exactly the results that it advertises.

An independent body called NSF International designates certain standards that products such as water filters will be tested against and held to.

NSF Standards 42 and 53 are usually signs that a filter can remove fluoride and chlorine. (NSF Standard 177 is also given for shower head filters effective in removing chlorine).

RO filter systems are also certified and tested against NSF Standard 58, which deals with fluoride reduction.

Flow Rate

Flow rate in regards to a water filter is simply the amount of filtered water that it can provide within a certain timeframe. This is particularly important for whole house filters.

Any water filter with very slow filtration can result in additional waiting periods or a decrease in water pressure.

Installation & Maintenance

Installing and maintaining water filters can differ, and is largely to do with the type of filter. For example, a whole house filtration system is more challenging to set up compared to an ordinary water pitcher filter.

Many filters don’t need to be installed (such as pitcher, gravity, bottle and countertop filters) making them cost effective and time saving!

Whole house and under sink water filters require sufficient installation. Sometimes this simply isn’t a DIY task and it’s worth spending the money on professional installation by a plumber.

Filtration Capacity & Cost

Filter capacity and overall cost go hand in hand. A filter with a long lifespan won’t require replacement very often, thus saving you a lot of time and money in the long term as you won’t constantly be buying and replacing new filters.

More on Water Filters for Chlorine and Fluoride

What Is Fluoride? What Is Chlorine?

Fluoride and chlorine are two naturally occurring elements that often have beneficial purposes in small quantities. For example, fluoride is added to some toothpaste to help strengthen teeth, and chlorine is added to swimming pools to keep the water clean. However, in large quantities, both can be very harmful to consume, especially in drinking water.

Water Fluoridation & Chlorination – How Chlorine and Fluoride Get Into Our Water Supply

In the US, fluoride is purposefully added to our water supply in hopes to strengthen teeth and reduce the risk of tooth decay. While this is effective in children, there’s less evidence of this working in adults.

Many countries in Europe have significantly declining cases of tooth decay as well and don’t add fluoride to their water, instead relying on toothpaste, which all suggests that fluoridating municipal water supplies might be unnecessary.

Chlorination of tap water in the US is for the purposes of disinfection, as it effectively kills bacteria, viruses and parasites that are leading causes of disease.

In this sense, chlorination can make drinking water much safer to consume. Since 1908, it’s been an effective method of removing waterborne pathogens like typhoid, which in turn saves countless lives and prevents grave sickness every year.

The CDC claims that chlorinating municipal water supplies was “one of the most significant public health advances in U.S. history” and that it increased life expectancy of the average American by an estimated 50% during the twentieth century.

Chlorination also removes bad smells and tastes!

Are There Health Risks Involved with Fluoride or Chlorine in Drinking Water?

As mentioned, both chlorine and fluoride are added to water supplies in order to remove harmful viruses, cysts and bacteria and also strengthen teeth. However, it can’t be denied that too much of these elements can lead to health issues.

Fluoride Consumption: Potential Health Effects

Once fluoride is introduced to water supplies, there isn’t a solid method of controlling the amount of fluoride each individual person will consume. This can be a bit alarming considering that most children have usually exceeded their daily fluoride intake through just nutrition.

There are many sources of fluoridation, including toothpaste, cookware, salt, milk, medications and also processed food, which all add to the daily consumption. Going too far over this intake can lead to consequences for our health.

As well as this, the human body is only capable of really storing half the amount of fluoride than it consumes, with the rest being passed out in urine.

Skeletal and Dental Fluorosis

Our bones and teeth store 99% of fluoride in our bodies. Joint pain and stiffness (skeletal fluorosis) and also dental fluorosis can be a result of overconsumption of fluoride.

The Thyroid

Thyroid gland function is interrupted by fluoride. It reduces the level of T3 & T4 thyroid hormones and increases THS levels, and over time this can sometimes lead to hypothyroidism – a condition where the whole thyroid gland’s function is suppressed.

Neurological Problems

Our pineal gland, brain and other soft tissues will carry the other 1% of fluoride. This can unfortunately lead to the pineal gland being calcified, and in the long term, fluoride overconsumption can lead to fatigue, sleeping disorders and depression.


Consistent consumption of high quantities of solute fluoride salt is usually the only method of fluoride intoxication. The majority of cases historically usually occurred after consuming pesticides that are based on fluoride.

Today, most recorded fluoride toxicity occurrences happen because fluoride products are ingested.

For a dose to be lethal in adults, fluoride per kg body weight needs to be around 32-64 mg.

Chlorine Consumption: Potential Health Effects

The safe amount of chlorine level in water is a maximum of 4 ppm.

Benefits of chlorine in a water supply are thought to outweigh potential safety risks from any disinfection byproducts. Water that contains small organic matter deposits can react with chlorine and form these disinfection byproducts, which leads to some troubling risks.

Disinfection Byproducts

Trihalomethanes (THMs) are some of the most worrying. Laboratory studies confirm that animals that were exposed to significant amounts of THMs had an elevated cancer risk. Studies performed on humans also showed that consistent exposure to significant levels of chlorine byproducts may be linked to an increase in cancer risk.

THMs can also impact pregnancy. One study showed how pregnant women that drank greater amounts of THM-heavy tap water developed a higher risk of having a miscarriage.

However, these studies do not actually have enough evidence to prove that chlorine byproducts are linked directly to cancer or miscarriages. Further research is needed to confirm this.

Skin Issues and Damaged Hair

Outer layers of our skin can be stripped of natural oils when exposed to chlorine. This leads to itchiness, dryness, and sometimes rashes. Some scientists believe it can contribute to premature ageing.

This can also happen to hair. Without natural oils, hair becomes brittle. Additionally, chlorine may change the natural color of hair.

How to Reduce Fluoride & Chlorine in Water

The American Dental Association states that the proper level of dissolved fluoride we need within tap water is 0.7 ppm for optimum dental health.

The ADA also states that even at higher levels, the amount of fluoride in US water supplies won’t go past 1 ppm. Contrasting with this, water without fluoride normally contains less than 0.3 ppm, though sometimes groundwater concentration may be greater.

When this is considered, you may be wondering if a water filter system can actually remove any level of fluoride successfully, or if it’s just inevitable that it ends up in drinking water regardless.

The Water Quality Association states four methods of treatment that are best suited for helping rid your tap water of fluoride (more below).

The simplest method to remove chlorine from water is filtration. Two primary methods of doing this are:

  1. Point-of-use filtration – each POU system will filter water at the point of use, which normally is a kitchen faucet. For example: RO water filters that are installed under kitchen sinks.
  2. Point-of-entry filtration – POE systems filter your whole water supply, allowing you to get water free of chlorine at every home source. For example: a whole house filter that is activated carbon based.

Considering how a large amount of daily chlorine and disinfection byproduct exposure comes from what we inhale through our lungs and absorb through our skin whilst showering (instead of what we drink), POE systems are a logical purchase.

Combining Multiple Filtration Methods

Activated Carbon

Regardless of what kind of chlorine filter you purchase, the most important factor would be that it uses at least one activated carbon block filter or GAC filtering stage (catalytic carbon filtering is also useful).

It’s possible for as much as 99.9% chlorine to be absorbed by carbon, trapping them in small pores on the surface.

Chlorine removal occurs due to contact with filter media. To say it differently – an appropriate size of carbon filter is crucial to keep in mind. The greater the flow of water that has to be filtered, the bigger your filtration system has to be.

UV Light

UV treatment is an alternative yet less effective approach to activated carbon. Broad-spectrum UV systems will reduce chlorine and chloramine deposits into byproducts that are easily removed.

UV wavelengths of 180 to 400 nm are the catalyst for photochemical reactions which separate hydrochloric acid/chloride ions that are free forming.


If no other method works, then a dechlorination agent (or dechlorinator) may work to remove or neutralize the chlorine in your water. Chemicals such as sodium thiosulfate & sulfite, potassium metabisulfite, and vitamin C will work to do this.

The biggest advantage of using a dechlorinator is their fast working time. 5 minutes is usually the longest period of time it takes to remove chlorine from water.

Activated Alumina (AA)

AA is an aluminum oxide that has a significantly large surface area and is very porous, and is often used for purification processes. As it does not dissolve in water, it’s an ideal material for use in a water filter that removes fluoride. In fact, the longer the water is in contact with the activated alumina filter media, the more fluoride will be removed.

Strong Base Anion Exchange

One of the most common filtering methods for water, strong base anion exchange is another effective method of removing fluoride.

Reverse Osmosis

Under Sink Reverse Osmosis System

An RO membrane by itself isn’t appropriate for chlorine filtration. In actuality, chlorine damages a reverse osmosis membrane.

Luckily, each RO system we tested will apply, at minimum, one carbon pre-filtration stage that eliminates the majority of chlorine before reaching the RO membrane!

Besides, reverse osmosis is great for removing fluoride.


Distillation results in water with very high purity. Neither chlorine nor fluoride can survive the treatment process.

Bone Char

Bone char filter media reduces fluoride + chlorine from water, but it’s not as effective as reverse osmosis or distillation. Generally, a higher volume of filter media is required. Also, many experts prefer adding activated carbon for more effective chlorine removal.

Can You Boil Chlorine and Fluoride Out of Water?

Chlorine can be removed from water quickly by heating it to a high temperature, but not quite boiling temperature. Heating it for between ten and twenty minutes should be enough, though this can vary depending on chlorine levels and how much water is being heated.

Unfortunately, boiling is not effective for removing fluoride from water.

How About Evaporation?

Around room temperature, chlorine is a gas which will gradually evaporate from water and release into the air surrounding.

In order to dechlorinate, water needs to sit for a certain amount of time, the length of which will depend on factors such as surface area, temperature of air and water, and the amount of chlorine dissolved in the water.

Example: When a flat yet large bowl of chlorine tap water is placed in sunlight, dechlorination will be significantly quicker in this manner compared to if a glass of water is placed in a refrigerator. UV light, circulation, and aeration can also quicken the process.

Water should sit for roughly 24 hours, despite the likelihood of the smell and taste of chlorine disappearing after a few minutes.

Chlorine testing strips can help you gauge how long this will take as well.

Again, evaporation does not help to get rid of fluoride.

The Different Types of Chlorine/Fluoride Removal Filters and How They Work

There are various types of water filters for both fluoride and chlorine. These filters use methods such as reverse osmosis purification, activated alumina absorption, strong base anion exchange, or simple distillation.

They can come in many forms, such as an RO system, whole house filters, a countertop or under sink filter, a water pitcher filter, a water bottle filter, a water distiller, shower filters, or inline filters.

Whole House Water Filters

While they can remove chlorine easily, a whole house filter that is purposed for fluoride removal is quite rare. This is due to the fact that successful fluoride removal can be very difficult. Our favorite system, the Crystal Quest, utilizes a sizeable mineral tank lined with bone char to give a fluoride reduction of 90-95%!

Water Pitcher Filters

Water pitcher filters are great at filtering drinking water. High quality models utilize a mixture of filter media in order to remove various contaminants (fluoride and chlorine being one of them).

Reverse Osmosis Systems

Reverse osmosis systems use multi-stage filtration. This removes over 90% fluoride and chlorine content from your drinking water. The semipermeable RO membrane is the most crucial element of the system, which carries out most of the contaminant elimination.

Under Sink Filters

Most under sink water filter systems also utilize several filter stages for removing chlorine and fluoride deposits in drinking water.

Gravity/Countertop Filters

Countertop and gravity filters use several filtration stages to leave drinking water clean and healthy to drink.

Inline and Fridge Units

Standard fridge water filters won’t remove fluoride. There is an inline water filter which will, however. It utilizes ion exchange based filtration in one single cartridge to do this. We recommend the CF Universal, which we reviewed above.

Filter Bottles

We have found the Clearly Filtered Water bottle to be highly effective at removing fluoride as well as chlorine. Using Affinity Filtration Technology, it removes 99.5% of both elements. All you have to do is suck water through a straw, and it’s filtered!

Shower Filters

The Propur ProMax (reviewed above) is so far the only shower filter that is anywhere close to providing adequate chlorine + fluoride reduction (about 50%).

Water Distillers

Distilling water is a highly effective method of fluoride and chlorine removal. It uses heat in the boiling chamber to increase the water temperature, until eventually all the liquid is evaporated.

Advantages and Disadvantages of Using a Water Filter to Remove Cl + F

Like everything, there are advantages and disadvantages to using various water filters for removing fluoride and chlorine from your drinking water.


Water Free from Chlorine and Fluoride

Obviously, a water filter will remove unwanted chlorine and fluoride from your water!

Even More Contaminants Are Removed

Not only will fluoride and chlorine be removed, but other contaminants will as well. This will lead to water that is even more pure and healthy to drink.

No Chlorinated Odor or Taste

When chlorine is removed, you’ll notice an improved taste and smell to your water.


While whole house systems are quite expensive, most other water filters (like filter pitchers and filter bottles) # are reasonably priced.


The majority of the filters we have reviewed above are simple to assemble, install and use.


Lack of NSF certification

A lot of water filters for fluoride and chlorine aren’t NSF certified or even tested for the removal of these elements. This means you should check each product for its certain reduction rates, which we have listed in our review for each product.

Frequently Asked Questions (FAQ)

  • Is there a water filter that removes chlorine and fluoride?
    Yes, there are water filters that remove chlorine and fluoride. You can check the comparison list on this site to check the best ones.
  • Does Brita remove fluoride and chlorine?
    All Brita filters do remove chlorine, but they are completely useless against fluoride.
  • Does tap water have chlorine and fluoride?
    Fluoride gets added into many municipal water supplies in the US but not all. The same goes for chlorine. Usually, city water is either chlorinated or chloraminated for disinfection. You should contact your municipality to learn more.
  • Are chlorine and fluoride in water harmful?
    The biggest concern about chlorine in water is that it creates unpleasant taste and odor. Fluoride can be harmful but only when consumed in extreme amounts. The real problem with tap water fluoridation, in our opinion, is that you cannot control who ingests how much of it.
