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 ProOne 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 ProOne ProMax, its specifications are as follows:

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.

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.

The following are key features worth considering when shopping for a fluoride and chlorine water filter. They will help you choose the right on for your needs and budget.
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.
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:
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:
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 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.
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.
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
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.
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!
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.
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.
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.
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.
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.
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.
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.
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.
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:
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.
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 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.
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.
One of the most common filtering methods for water, strong base anion exchange is another effective method of removing fluoride.
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 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.
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.
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.
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.
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 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 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.
Most under sink water filter systems also utilize several filter stages for removing chlorine and fluoride deposits in drinking water.
Countertop and gravity filters use several filtration stages to leave drinking water clean and healthy to drink.
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.
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!
The ProOne ProMax (reviewed above) is so far the only shower filter that is anywhere close to providing adequate chlorine + fluoride reduction (about 50%).
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.
Like everything, there are advantages and disadvantages to using various water filters for removing fluoride and chlorine from your drinking water.
Obviously, a water filter will remove unwanted chlorine and fluoride from your water!
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.
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.
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.
