The Best Fluoride Water Filter Reviews For 2020

1. APEC Water Systems RO-90 Ultimate Series

The APEC Water Systems RO-90 Ultimate Series is a five-stage water filter that uses reverse osmosis to filter your drinking water. It produces 90 gallons of filtered water per day with high-capacity, long-lasting filters.

The filtration system is designed to accommodate medium to large households with average to above-average water consumption.


  • Model Number: RO-90
  • 17 x 6 x 18 inches
  • 5-stage ultra-pure system
  • WQA Gold Seal certified
  • Filters over 1,000 contaminants
  • Lead-free chrome faucet
  • FDA certified JG food-grade tubing

The APEC Water Systems RO-90 Ultimate Series offers one of the best values for fluoride water filters on the market. It has the WQA Gold Seal certification and is widely considered one of the best filtration systems on the market.

Of course, fluoride filtration is one of our primary considerations through our reviews, but that’s far from the only harmful chemical that the RO-90 filters. The system works had at the removal of over one thousand contaminants (including arsenic and chlorine), which falls in line with the fantastic quality reputation APEC filters have.

The capacity of 90 gallons per day is more than enough for most households, but it may depend on individual elements like local water quality, water pressure, and temperature of your water.

Realistically, almost everyone can expect this filter system to produce at least 70 gallons of filtered water – even if you have more water contaminants than most people do.

Installation is relatively easy with the APEC RO-90. Most people install it under the kitchen sink, but you can put it in a basement or above the counter as a countertop installation as well. The installation manual is easy to understand is available online if you misplace your original copy.

The filter life is one of the most positive attributes of this filtration system. Most people can go a year on a single filter if they need to, though two per year is more realistic. This will save you money in the long run, especially if you’re looking at one of the cheaper options.

  • Long-lasting filters
  • Provides great value
  • Quickly produces water
  • Shows water quality
  • 1-year warranty
  • No pH filter
  • Reported water pressure issues after prolonged use

2. iSpring RCC7AK 6-Stage RO Filter


The iSpring RCC7AK 6-Stage water filtration system is another top fluoride filter option if you’re trying to filter out fluoride and other harmful chemicals in your water. The system uses an extra stage to help balance the pH of the water and return some of the beneficial minerals to it.

Some five-stage systems will strip the water of its minerals and leave it on the acidic side. The RCC7AK prevents this from happening.

With a 75-gallon daily capacity, this filtration system should serve the needs of most households. Only massive homes with water consumption that is well above average will need more. The system includes a faucet, filtration system, filters, and a pressurized tank for water storage.


  • Reverse osmosis water filtration system
  • Removes up to 98% of contaminants
  • Feed water pressure: 45-70 psi
  • 6-stage water filtration to restore healthy minerals and pH
  • Brushed nickel faucet
  • 15 x 8 x 18 inches

One of our preferred picks for fluoride water filters is the iSpring RCC7AK 6-Stage water filtration system. It’s easy and straightforward to install, with a capacity that will serve almost any size of household. The system uses the sixth stage to balance water pH to ensure you’re always getting healthy, clean water through your tap.

All filtration systems will lose some water throughout the filtering process. The majority of systems will use about four gallons for every one gallon of purified water they produce.

The iSpring RCC7AK only uses three gallons of water to produce a single gallon of purified water, which will save you some money. Of course, this is an average number and will vary depending on the water pressure, temperature, and quality of water in your area.

  • 4-gallon water storage tank
  • Made in the USA
  • Replacement filters are affordable
  • 75-gallon daily output
  • Removes up to 98% of water contaminants
  • Filter life could be longer
  • Can waste some extra water in certain homes
  • No UV light feature

3. Aquagear Water Filter Pitcher


The Aquagear Water Filter Pitcher is a highly-effective, certified, clean water filter pitcher for those who want an easy way to get their drinking water from the tap. You can fill it up, keep it in your fridge, and drink from it when you want some fresh water.

The pitcher has held up under the harshest water conditions, providing fresh water to those with several harmful contaminants.


  • Pitcher water filter
  • 100% BPA-free and FDA approved
  • 100% Recyclable and vegan
  • NSF standards 42 and 53 compliant
  • Tested in Flint, Michigan
  • 150-gallon filters
  • Removes 2000% more contaminants than Brita
  • Lifetime guarantee

The Aquagear Water Filter Pitcher is one of the best fluoride pitcher filters on the market.

Pitcher filters are easy to use, cheap, and allow you to keep the water cold in your fridge. A lot of people gravitate towards brands like Brita for their pitcher filtration needs, but the Aquagear pitcher is a whole lot more effective when it comes to removing fluoride and other contaminants than other pitchers.

This fluoride filter pitcher will eradicate 90% of the fluoride in your drinking water, which is about as effective as the under-the-sink filtration systems we’ve covered above. The pitcher is made from the highest quality materials and comes with a lifetime warranty, so you don’t have to worry about it failing over the years.

Although this is our top pick for the best pitcher filter for fluoride, there are a couple of drawbacks to it. The first is in the pitcher size. It only holds half of a gallon (not uncommon among pitchers), so you will probably need to fill it several times per day if you use a lot of water.

There also isn’t an indicator that tells you when it’s time to change the filter, meaning you’ll have to keep track of that on your own.

Overall , it is a solid product you should consider buying if you’re on the market for water filters that remove fluoride in the pitchers form factor.

  • Long-lasting filters
  • Durable build
  • Lifetime warranty
  • Removes 90% of fluoride
  • Filtration time is slower than average
  • No filter change indicator
  • Pitcher only holds half of a gallon

4. Culligan FM-25 Faucet Mount Filter


Those who want fresh water on-tap without installing a water filtration system under their sink will want to look at a faucet mounted filter. The Culligan FM-25 Faucet Mount Filter is just that, with easy installation that doesn’t require any additional tools.

This filter removes harmful contaminants (including fluoride), bad odors, and poor taste from your drinking water. It allows you to turn the filtration on and off with a switch, meaning you can reduce water waste if you’re not making yourself a drink. This is an activated carbon type of filter in the cartridge.


  • 5 GPM flow rate
  • 60 PSI
  • Switch for filter/no filter
  • No tools needed for installation
  • Removes contaminants, odors, and poor taste from water
  • 2-month filter lifespan
  • NSF certified

Our top faucet mounted option for fluoride filtration is the Culligan FM-25 Faucet Mount Filter. It’s one of the best fluoride filters on the market and doesn’t require any installation. The filters will last two months or more as well, which means you can save a lot of money over time.

Those who are looking for fresh water in their kitchen without paying high prices for under-sink filtration systems would do well to add the Culligan FM-25 to their shopping list.

The filter looks sleek with its all-metal design and fits snugly against your faucet, which can reduce clutter and even more convenient and space-saving than a countertop system. Although the water pressure is relatively high, it filters water much more slowly than you’ll find with an under-sink filtration system.

The product is no slower than similar filters we’ve seen, so you should look at this as a trade-off for choosing a faucet attachment rather than an under-sink unit.

Other than that, the faucet filter works spectacularly and lasts a long time.

  • Allows you to switch from filtering to not filtering to save water
  • Above average filter lifespan
  • Great water pressure
  • All metal components
  • Filters water slowly
  • Does not fit drop-down faucets

5. Pure Water Mini-Classic CT Counter Top Distiller


Those who prefer a countertop water distiller over a pitcher, sink attachment, or filtration system can find one in the Pure Water Mini-Classic CT Counter Top Distiller. The distiller holds a gallon of water and distills it to its purest form, ridding it of fluoride and other harmful water contaminants.

The distiller is easy to fill and easy to clean when you need to. You don’t have to spend money on costly filters over time, and can instead invest in some high-quality jars to store your distilled water.

The fluoride filter device will handle nearly everything you throw at it, which lead us to include it on our list of best fluoride water filter options.


  • Sits on countertop
  • 800 watts
  • Distills water with vapor
  • Made in the USA
  • One-gallon capacity

The Pure Water Mini-Classic CT Counter Top Distiller is a great addition to the home for those who want distilled water rather than filtered water. Distilled water is perfect for avoiding harmful contaminants and bacteria, and there’s no assembly or installation required. This type of system doesn’t use activate carbon or active alumina like other types of fluoride filter systems.

Distilled water systems like this one also allow you to save a bit of money on filters. It can be difficult to remember when the time comes to change your filter, but the Pure Water Mini-Classic CT Counter Top Distiller removes this issue.

One of our favorite parts of this water distiller is its size. Sure, you’re not going to be able to filter more than a day’s worth of water with the system, but you can put it on your counter or in your fridge to have some clean, clear water for later.

We would probably recommend a full system or faucet attachment for larger households, but this water distiller works perfectly for those who live alone or with one other person. It will save you some money on filters and make sure you’re always drinking fresh, clean, distilled water.

  • No installation needed
  • Distills water quickly
  • Filters all harmful contaminants
  • Some users reported long-term durability issues
  • Some users complained of “off taste” when using distiller

6. Aquasana 10-Year, 1,000,000 Gallon Whole House Water Filter For Flouride


The Aquasana 10-Year, 1,000,000 Gallon Whole House Water Filter is a filtration system that will rule out fluoride and other contaminants in your entire home.

Unlike the other products we’ve included, this system will tackle more than just the drinking water. It will ensure that you’re never using contaminated water for showering, washing dishes, or anything else. It features an activate carbon filtering stage, which is a very common and highly effective solution. A few other systems use activate alumina, but activated carbon is by far the most popular.

This filtration system is certified to last ten years or one million gallons – whichever happens first. For some, it means that you won’t have to buy any other form of water filtration for the length of time they’re in their home. Of course, this product is geared towards those who own property rather than those who rent.


  • 1 million gallons or 10-year lifespan
  • Includes filtration tank, 20” pre-filter, post-filter, brass fittings, bend supports, and shut-off valves
  • Removes 97% of chlorine
  • Removes 99.99% of viruses and bacteria with UV sterilization
  • Salt-free softener
  • 9 x 46 x 69 inches
  • 7 GPM flow rate

The Aquasana 10-Year, 1,000,000 Gallon Filter is our selection for the best whole-house filtration system. It won’t appeal to everyone, but it is the best option for those who want all of their water fluoride and contaminant-free.

Once you install the filter system, all you have to do is turn on the faucet for clean, pure, water. It uses an all-natural, salt-free water softener to get rid of hard water at the source, so you’ll be improving your water quality outside of just filtering contaminants.

The biggest drawbacks for the Aquasana whole-house filtration system are the same for any product in the same category. The system is very large, which means you’ll need to be sure you have enough space to install it.

Installation can also be very difficult, and those who don’t have experience with plumbing and water filtration installations probably won’t be able to do it alone. Most buyers will probably need to hire a professional to install the system, which is an added cost on top of the thousands of dollars the system costs.

Still, if you’re looking for a whole-house filtration system to get rid of any fluoride in your water, the Aquasana 10-Year, 1,000,000 Gallon Filter is your answer.

  • Provides long-lasting, whole-house water filtration
  • 10-year warranty
  • Removes almost all contaminants
  • 3-month money-back guarantee
  • Large system
  • Difficult to install – will likely need a professional

Pre-Purchase Considerations

Before you decide on a water filter that removes fluoride , there are a couple of things you should consider. Ahead, we’ll cover these pre-purchase considerations so you can decide which product and filter type you want to use in your home.

What Type of Filter Do You Need?

We’ve covered four different kinds of water filtration systems in our review: under the sink, whole house, counter distiller, and faucet attachment. The filtered water option that is best for you will depend on your needs.

Are you in it for the long-haul with your home and want to ensure that all of your water is contaminant-free? If so, you’ll probably want to invest in a whole-house filtration system like the Aquasana product we included.

These cost a lot more than other filtration techniques, but they can put your mind at ease knowing that all of your water is healthy and contaminant-free.

Those who own a home but worry more about their primary water source will want an under-the-sink filtration system. These only provide filtered water from one faucet, but they are relatively cheap and easy to install. Instead of spending thousands, you can spend hundreds and install the system yourself.

Renters will probably want to look at pitchers, faucet attachments (which typically use activated materials such as activated alumina), or distillation systems. You can take these with you from apartment to apartment and replace the filters as needed.

Think about your water usage, how much water you drink, and your housing situation when shopping for fluoride water removal filters. After that, you’ll know what kind of product interests you the most in providing filtered water.

How Harmful Are Your Contaminants?

Another consideration you should make relates to the number and severity of the contaminants in your water. You can contact your local water system to ask about what might be in your tap water, which we highly recommend before investing in a system.

This information will tell you how severe your water contamination might be. Although we focused on fluoride contamination with this review, it’s far from the only harmful chemical or contaminant that’s likely in your water supply.

Armed with knowledge, you’ll be able to make an informed decision on the right filter for you to reduce your exposure to contaminates by consuming only filtered water. Those with light contamination will probably be fine with pitcher filters and faucet attachments. These products will filter your drinking water and won’t cost much to operate. You can view Amazon product pages to see how little it can cost to acquire and operate most of the popular products on the market that are sold on Amazon. Including whole-house systems, countertop systems, faucet systems, and under-sink filter systems. Whether you choose a countertop system or another, removal of all types of contaminates (such as chlorine) is the benefit you want for your household.

People who live in areas with a high risk of contamination should take water filtration more seriously (by leveraging common filtering methods such as activated carbon or activated alumina). These individuals should focus on whole-house systems if possible, to root out any contaminants that might be harming their skin while they shower. Under-the-sink systems can also be useful here, especially if you currently rent an apartment.

How Does Fluoride Affect the Human Body?

First and foremost, we want to cover why there is fluoride in many water systems in the first place. With so many negative effects of the stuff, it’s easy to wonder why it’s made its way into many of our local water supplies.

Fluoride is naturally occurring. You can find it in the soil, water, and food. Almost all of the benefits of fluoride revolve around oral hygiene. It strengthens teeth, prevents decay, and prevents cavities. That’s why most toothpaste, floss, mouthwash, and other dental products contain fluoride in one capacity or another.

There’s also a reason that you’re not supposed to swallow your toothpaste and mouthwash when you’re done cleaning. Fluoride can have some devastating health effects when you ingest too much of it, which is why a lot of people are taking steps to remove it from their drinking water.

Ahead, we’ll take a look at some of the harmful effects fluoride can have on the human body.

Dental Fluorosis:

Dental fluorosis is probably the most common effect fluoride can have on the body, especially if a child is consuming too much fluoride. Although the condition doesn’t present any severe health problems, it can lead to white streaks on teeth that are undesirable.

This condition is most common in children and can be caused by too much fluoride in the drinking water. You should also make sure your children aren’t swallowing toothpaste or mouthwash, as this can lead to dental fluorosis over time.

Skeletal Fluorosis:

A more severe version of dental fluorosis is skeletal fluorosis, which happens when the excess amount of fluoride invades your bones and joints. When this happens, your bones harden and become more difficult to move. Skeletal fluorosis can lead to an increased risk of breaking bones over time.

Since skeletal fluorosis also affects the joints, you may find that it’s more difficult or uncomfortable to move around.

Mental Issues:

One of the more concerning effects that fluoride has on the body occurs in the mind. Children who ingest too much fluoride are at risk of developing cognitive problems as they age. It’s even considered to be a neurotoxin for children and is in the same category as known contaminants like lead and arsenic.

These potential mental issues are among the biggest reasons parents are trying to get fluoride out of their drinking water.


Hyperparathyroidism is a condition that causes your thyroid gland to produce hormones uncontrollably. Too much fluoride can damage the gland and cause the condition, which will lead to calcium depletion in your bones.

When the calcium in your bones drops, you’ll be more likely to break something after a short fall. Ironically, fluoride is supposed to strengthen your bones.

Fluoride Poisoning:

Fluoride poisoning is the most severe effect fluoride can have on the body. We should note that it’s very unlikely to obtain fluoride poisoning from your drinking water – especially if there was no chemical contamination to the source. Still, it’s something you should consider when looking for a water filter.

The symptoms of fluoride poisoning include nausea, abdominal pain, seizures, muscle spasms, and excess saliva.

How Does Fluoride Get into Water?

Fluoride occurs naturally, so it’s common to find it in the drinking water – even if it’s just a little. Some areas are more prone to fluoride contamination when it naturally occurs in the rocks and soil surrounding the water source.

One troubling reality is that some local jurisdictions add fluoride to their drinking water. This is all in the name of improved dental health, but the trade-off is far from understandable.

You should check with your local water source to find out if whether or not they add fluoride. These decisions happen on a local scale, so the only way you will know is if you ask.

How to Remove Fluoride from Water

The best way to avoid any fluoride in your drinking water is to invest in a quality filtration system. Areas that add fluoride to the water are at the greatest risk, and those who live there should look into whole-house filtration systems.

Pitchers, water filters, and other forms of filtration will assure that you remove all of the fluorides from your drinking water. These strategies don’t cost very much when you consider the long list of harmful effects fluoride can have on the human body.

Questions and Answers

Will fluoride reverse tooth decay?

No, but brushing with fluoride products will help prevent decay.

Can fluoride kill you?

In theory, enough fluoride can kill you. It’s almost impossible for an adult to die from drinking too much tap water with fluoride in it, though.

Is fluoride free toothpaste effective?

Somewhat, but you should still keep fluoride in your toothpaste – just not your drinking water.

Why is fluoride in the drinking water?

To strengthen teeth and prevent oral diseases.

Can fluoride cause brain damage?

Yes, it can cause brain damage in both children and adults if they consume too much.


Fluoride is a harmful chemical that is far too common in our water sources. It can cause a long list of severe and minor health problems, which are far from good trade for healthy teeth. Brushing and flossing are enough to keep your teeth healthy – we don’t need extra fluoride in our water.

Thankfully, there are several products and filtration systems that can effectively remove the fluoride from our drinking water. These filters remove other harmful chemicals as well, so it makes sense to invest in one kind of filter or another – regardless of your risk level.
