Buyer’s Guide – How to Buy the Best Water Fluoride Test Kit (+ How We Tested)

Here’s our buying guide with everything you need to know about how to buy the best fluoride water test kit.

Water Source Type

What is your water source type? Are you on well water or city water?

Before purchasing a fluoride test kit, you need to determine your water source.

That’s because a few water tests are meant to target a particular type of water source. For instance, some testing kits detect contaminants especially fond in well water while others are designed for municipal water, aquariums, pool water, etc.

Make sure you buy an appropriate fluoride water test kit suitable for your water source.

Certified Lab Testing vs. DIY Test Strips

We included reviews for DIY fluoride test strips and lab tests alike. However, we highly recommend lab tests. Why? Read below:

  • Accuracy. Test results provided by a certified laboratory are far more precise than the tests you perform at home using DIY testing kits.
  • Comprehensive contamination detection. DIY test strips can gauge only a few items in your water. On the flip side, most send-away kits are not limited to one or two dozen analytes. Instead, they can test your water for an unlimited amount of contaminants, impurities and factors if you want. Aside from fluoride, these include chemicals, heavy metals, and microorganisms.
  • Expert handling. Trained laboratory experts use special, systemized methods to test your water. On the contrary, DIY tests are highly prone to errors, which means you may end up getting false results.

Testing Procedure Accuracy

A state or certified laboratory gives the most precise results for water quality.

While this sounds pretty satisfying, make sure you do not mess up while collecting your water sample. Otherwise, you’ll be contributing to inaccurate results.

If you collect the water sample properly, you can trust most labs for highly reliable results.

Sadly, we cannot say the same for DIY fluoride test kits…

A few only test your water for fluoride but don’t even specify the exact levels. Others take measurements in increments that are far too big.

For instance, fluoride is added to tap water at 1 part per million. If a test can calculate fluoride concentrations up to 100 ppm, it’ll be challenging to differentiate between 0.5, 1.0 or 2.0 ppm by comparing colors.

And this is not the only issue. Most DIY testing kits come with detailed guidelines on collecting a sample and testing the water, which is great. On the downside, the procedure can be confusing and not comprehensible at all.

To give you an example: You may be required to insert a strip in water for 2-3 seconds. Then, you have to remove excess water and wait for 30 more seconds before comparing the strip color to a colored chart for the next 30-50 seconds. Well, this doesn’t seem like a reliable testing procedure. What if you’re too slow or too fast?

Other Water Parameters/Impurities/Contaminants

It’s close to impossible for your water supply to contain no other elements than fluoride. Several chemicals, heavy metals, and harmful microorganisms might be swimming in there, and you won’t even know it.

Therefore, it’s best to test your water for all contaminants commonly found in tap or well water. How? Through a comprehensive water analysis!


A credible laboratory will send you your water analysis report via email. This report will include all the information about your water conditions, including plumbing problems, aesthetic water issues, and potential health effects.

In addition, the lab experts compare the measured contaminant levels to state and federal limits and public health guidelines.

What else is good? Many reports also suggest options for the most appropriate way of treatment – think water filters and softeners.

Turnaround Time

Do-it-yourself water fluoride test kits shine solely because of their quick turnaround time. The moment you perform the test, you can measure the results.

Send-away kits, on the other hand, take a lot of time. For instance, a few kits can take up to 3 weeks before you get the testing results. That said, the time limit differs from supplier to supplier.


A comprehensive send-away test kit can cost you hundreds of dollars but gives precise and reliable results.

DIY test kits, on the other hand, are pretty affordable. The average price lies somewhere between $10-30 for 100 strips! But, again, you’ll have to compromise on the results – they might not be too accurate.

How Does Fluoride Get into Our Drinking Water?

Research shows that water fluoridation decreases and prevents tooth decay by around 25% in adults and children. Due to this reason alone, water utilities mix fluoride into their water so users can benefit from it.

However, how far these findings are legitimate is another discussion. Does fluoride actually prevent tooth decay, or is it just a myth?

Studies conducted by the University of Harvard[2] show that water fluoridation might not be that much of a helpful health measure. In fact, many first-world countries have refused to add fluoride into their water supplies.

The result? There was and still is a decline in the number of cavities recorded.

Besides, fluoride is a natural mineral and already exists in water. Yes, the amount is far less than what’s added in water supplies; but it’s still beneficial.

The fluoride mineral travels from rocks into the soil, and either makes its way to the surface water or enters groundwater.

Natural Sources of Fluoride

Natural Fluoride Crystal

Fluoride is a naturally occurring mineral. Several rocks, plants, food, soil and even water bodies contain fluoride in small amounts.

First, the element is released from rocks into the soil. It then flows to surface waters or makes its way into the groundwater.

Furthermore, foods like grapes, tea, spinach and coffee are naturally-rich in fluoride.

Water Fluoridation

Water fluoridation refers to the adjustment of fluoride in the public water supply to the extent required to prevent tooth decay.

And it’s true: Research shows that fluoride guards against tooth decay. This explains why most toothpaste contains the mineral as an active ingredient.

Though mouthwashes, dietary supplements and other items also have fluoride, water fluoridation offers a cost-effective way to prevent tooth decay.

How? It delivers fluoride to all users connected to public tap water systems.

When municipal water supplies started adding fluoride to water back in 1962[3], the suggested amount was up to 1.2 ppm. Today, it is 0.7 ppm precisely.

Testing Your Water for Fluoride: How to Do it?

best fluoride water test kits thumbnail

Most US cities have fluoridated water. Therefore, the easiest way to determine whether or not your water supply has fluoride is to speak to your local water supplier.

They’ll inform you whether your water has fluoride or not. If it does, they’ll let you know its average concentration.

Fluoride levels are generally measured in ppm or mg/L.

If you’re feeling creative and want to test your water yourself, you can do it. Below, we’ll uncover a few common ways to test fluoride levels in drinking water.

Professional Lab Testing

If reliability is of prime importance to you, professional lab tests are hands down the best option. The experts in said labs can provide you with the most precise results.

And if you want, you won’t only get to know about the fluoride levels in your water, but all the impurities, contaminants and physical factors of your water supply.

Yes, you’d need to pay more for the extra information, but it’s worth it. Most reports also help you select the best and most appropriate treatment option for your water conditions.

Be sure to go for an EPA-certified lab, though. Such laboratories perform quality tests conforming to official standards.

On that note, you can find a nearby laboratory on the official EPA website. Once you’ve selected a befitting lab, here are a few steps to take.

  1. Reach out to the lab and enquire about the accurate way to collect the water sample.
  2. A few labs prefer you collect samples in their disinfected bottles. If the one you chose asks so, you can visit the lab, take the bottle and then carry on with the procedure.
  3. After collecting the sample, send it away.
  4. An experienced lab professional will design a comprehensive report of your water quality under strict regulations.


  • A legitimate water quality report with the most precise results.
  • Tests your water for dozens of impurities – if you pay for it.
  • The testing report outlines the most suitable water treatment solutions based on the contaminants found in your water.


  • You’d need to wait for a couple of days – you can’t get the results right away.
  • The testing process is a bit expensive.

DIY Testing Strips

DIY test strips offer the most budget-friendly way to check your water for fluoride. Besides, they include easy-to-follow instructions and provide results immediately, unlike a lab test.

You only need to dip a testing strip in the water, wait for a few seconds, take it out and match the strip’s color with the provided chart.


  • The package comes with straightforward instructions.
  • They are pretty affordable and readily available at your nearby local stores. You can also buy them online through Amazon or eBay.
  • It may be possible to obtain relatively precise results if you don’t commit even a slight error during testing procedure.


  • A few DIY testing kits only test your water for fluoride and no other contaminant in your water supply.
  • Several kits are only yes or no tests. Simply put, they do not tell the exact level of fluoride in your water.
  • Instructions are sometimes rather vague.
  • Highly prone to errors resulting in inaccuracies.

Reactive Test Kits

You can also use reactive test kits to test your water for fluoride. Here’s how they work.

  1. Fill a disposable bottle with water.
  2. Add the reagent to the water and close it.
  3. Mix the solution.
  4. Add the sample to the photometer, and wait for a moment. It will reveal the electromagnetic changes in your water.
  5. If your testing kit includes a colored chart, you can compare the solution color with it.


  • Reagent water testing kits give more precise results.
  • You can buy them for under $100 – not expensive.


  • Committing a slight error when performing the test may give inaccurate results.
  • The photometer might need calibration. Besides, you may need to experiment for a while to figure out how it works.

The Downside of Do-it-Yourself Fluoride Test Strips

If you’re looking for the easiest and the most affordable way to test your water for fluoride, DIY testing strips are the best option for you.

You can buy them for less than $50. Once you have the package, you only need to fill a glass with water and insert a strip.

Later, you have to match the strip’s color with the chart provided.

However, we do not recommend DIY testing kits for a few reasons.

  1. A few testing kits only determine the presence of fluoride but don’t point out the precise concentration of the mineral in your drinking water.
  2. Often, the testing procedure is so rushed that we couldn’t measure precise results.
  3. Comparing colors feels pretty subjective and is nowhere close to an exact science.

Therefore, it’s better to go with send-away test kits in our opinion. A lab expert uses a systemized procedure to test your water for fluoride and possibly other analytes. Sure, you’re required to pay extra for additional information, but it’s worth the money.

Getting in Touch With Your Water Utility or Municipality

As an alternative to conducting your own testing, you can get in touch with your municipality and ask them if they mix fluoride into the water supply. If the answer is positive, get to know the exact amount of the mineral.

You can also reach out to the water utility directly and ask them.

Besides, you’re entitled to a free annual water quality report from your utility. However, note that the report might not highlight fluoride in the list of impurities. Because fluoride is added deliberately to prevent tooth decay, it may not be considered worth listing.

How to Remove Fluoride from Water?

Removing fluoride from water is no rocket science.

Use a Water Filter

For one, several types of water filters available on the market can do the job for you.

The most potent fluoride filter media include bone char, activated alumina and reverse osmosis membranes.

Bone Char

Don’t let its bland name fool you; this filter media works great for fluoride removal.

Bone char is highly porous and produced by charring animal bones. It mostly comes in granular form and is black in color.

Besides removing fluoride, bone char filter media also eliminates radioactive particles, heavy metals, and other dangerous substances found in water.

Reverse Osmosis Membranes

under sink reverse osmosis system with storage tank

Your water passes through a semipermeable membrane with 0.0001-micron pores in a reverse osmosis filtration system.

Fluoride particles are considerably bigger than water molecules. Hence, the media rejects them. This way, reverse osmosis can remove 95% fluoride from water – pretty impressive!

Activated Alumina (AA)

Activated alumina has shown to reduce fluoride from 10 to 1 ppm in water.

AA filters contain porous aluminum hydroxide with a remarkable ability to remove fluoride. Nonetheless, the effectiveness depends on water pH, temperature and volume of the filter media.

How Else to Reduce Your Daily Fluoride Intake

A fluoridated water supply doesn’t make up 100 percent of your daily fluoride intake. Instead, several other sources add to your fluoride consumption, too.

Therefore, you can tackle the problem differently and avoid other fluoride sources in order to prevent overconsumption. Here’s how:

  1. Reduce the consumption of processed foods. Processed foods like soups, cereals and fish are prepared with fluoridated water. While it might be impossible to cut down on processed foods entirely, you can always reduce the total intake.
  2. Eat organic fruits and vegetables. Conventional farmers often use fluoride-containing pesticides. So, if you’re consuming inorganic foods, you may be increasing your fluoride intake.
  3. Exchange fluoridated dental products with non-fluoridated ones. This goes particularly for toothpaste. You can speak to your dentist so they can inform you about the risk of tooth decay.
  4. Avoid Teflon cooking utensils. Teflon utensils are made with fluorinated material. Try looking for alternative cooking utensils.
  5. Medicines. A few medications also include fluoride. Ask your doctor to prescribe you a fluoride-free substitute.
  6. Bottled water can also be high in fluoride. Nonetheless, it depends on the source from where the water was filled. Read the label to be sure about it.
  7. Brewed tea and coffee are also high in fluoride. Fluoride from rocks seeps into the soil, which plants later absorb. But, again, the fluoride concentration differs from company to company.

Health Effects of Fluoride in Drinking Water

People are suspicious whether fluoride is healthy or harmful. Sadly, most US citizens consume more than the daily amount of fluoride recommended by the EPA. Common sources include processed foods, tea, coffee and medicines.

Further, almost all dental items include fluoride. On top of that, we are consuming fluoridated drinking water, too. This can lead to…

Dental and Skeletal Fluorosis

Excessive intake of fluoride can weaken bones. This can lead to joint damage and even joint dysfunction in more severe cases.

Fluoride accumulation can also lead to dental fluorosis, causing discoloration and disfiguration of teeth in children.

Fluoride Intoxication

Excessive fluoride intake can cause intoxication. However, it happens in very rare cases only.

Tap water has a restricted amount of fluoride that doesn’t lead to intoxication.


Consuming a high amount of fluoride can lead to hypothyroidism – a condition when your body doesn’t create enough thyroid hormone to meet the daily needs.

Eventually, it can cause joint pain, obesity, heart disease and even infertility.

Early symptoms include hair loss, extreme fatigue and constipation

Neurological Issues

Fluoride intake can cause several neurological problems, including reduced IQ in children, slow cognitive development and ADHD.

What’s more, if the pineal gland – an organ that controls the sleep cycle – absorbs fluoride, it can lead to sleep problems.

Hence, these neurological problems can contribute to poor quality of life.

Frequently Asked Questions (FAQ)

FAQ thumbnail

How can I test my water for fluoride at home?

If you insist on at-home testing, you can use a DIY fluoride water test kit. These are readily available at local hardware stores for little money. If you make sure to follow the instructions precisely, you may even get reliable results.

How do I know if fluoride is in my water?

There are several ways to find out if your water contains fluoride. You can have your water tested or perform a test yourself. Or, you can contact your local municipality or water utility and ask if they fluoridate the public water supply.

How do you extract fluoride from water?

The best way to remove fluoride from water is using a fluoride water filter such as a reverse osmosis system.

How many ppm of fluoride is in tap water?

The optimal level for fluoride in tap water as recommend by the HHS is 0.7 milligrams per liter.[4] This amount is considered to promote dental health while minimizing the chance for dental fluorosis.

Is there fluoride in bottled water?

Bottled water may or may not contain fluoride. This entirely depends on where the bottled water was sourced from. If it was sourced from a fluoridated water supply, it certainly contains fluoride. Natural spring water can also contain the element but in lower amounts.


Fluoride test kits can be used to determine fluoride levels in residential water supplies. But, make sure to choose one that provides accurate results suited for your type of water source. Our favorite kit is Tap Score’s Fluoride Water Test. If you also want to conduct testing for other water parameters, impurities and/or contaminants we recommend the Tap Score Essential Well/City Water Test.
