🧫 How to Test Water for Fluoride

The three most common fluoride testing options are laboratory testing, at-home test strips, and fluoride testing meters.

Laboratory Testing

Lab testing is the best way to measure fluoride levels. There are hundreds of certified labs across the country that offer dedicated fluoride tests or test packages that include fluoride.

If you choose to test your water with a laboratory, the responsibility’s off your shoulders. You’ll just need to take a sample of your water and send it off to the laboratory (some labs will send you a prepaid return shipping label, but some don’t, so always check before you buy).

You’ll then receive your results in the post or via email, usually within four days.

Pros and Cons of Lab Testing

Pros:

  • Test reports are detailed and accurate
  • State-certified labs are reliable
  • Hands-off, hassle-free testing option

Cons:

  • The most expensive option
  • Doesn’t deliver immediate results

At-Home Test Strips

At-home test strips are DIY tests that can be conducted at home. These tests typically cost less than $30 and are widely available in hardware stores and online.

A DIY test kit comes with all the required materials to conduct a water test at home, including test strips, a color chart, and an instructions leaflet.

To use an at-home test strip kit, just collect a sample of your water in a glass and dip a test strip into the water. The test strip will change color to indicate the presence of contaminants. Compare the color of the strip to the included color chart to work out your water’s fluoride levels.

Fluoride Testing Meters

Fluoride testing meters are an advanced alternative to DIY test kits. They don’t use test strips or a color chart; instead, they take an electronic reading of water’s fluoride levels using an ion-selective electrode.

Consider buying a fluoride testing meter if you want a more accurate means of testing fluoride at home that delivers instant results. However, these devices are best suited to tech-savvy users because they can be challenging to configure and calibrate.

  • Expensive option

📝 Things to Consider Before you Buy a Fluoride Test Kit

Don’t buy a fluoride test kit without considering the following:

Your Water Source

The majority of fluoride tests are geared towards a certain water source. For instance, if you buy a test package that also tests for chlorine, heavy metals, and nitrate, it’s probably designed for municipal water. Alternatively, a test kit that tests for bacteria, iron, and hardness is probably designed for well water testing.

To get the most out of your purchase, make sure you buy a test kit that’s suitable for your water source.

DIY Vs Lab Testing

When choosing how you’ll test for fluoride in drinking water, you’ll need to decide between lab testing and DIY testing. There are pros and cons to both of these types of testing.

Lab testing gives guaranteed accurate results and can test for hundreds of contaminants at a time, while DIY testing can detect a limited set of contaminants and is vulnerable to errors and inaccuracies. However, lab testing is much more expensive than DIY testing.

Ultimately, we’d recommend lab testing, but if your budget can’t stretch that far, a DIY test is a good second-best option.

Diy vs lab water test results

Your Water Quality

The quality of your water, and what else it contains aside from fluoride, could play a role in the type of test you opt for.

Think about which other harmful contaminants you’re concerned about in drinking water. For instance, chlorine and lead are common city water contaminants, while microorganisms and iron are common in well water.

Fluoride might be the number-one contaminant you want to test for, but you’ll often get a better value for money from a test kit that detects multiple contaminants.

Testing Results

The type of test you conduct will determine the results you receive.

At-home tests deliver basic results. You simply compare the color of the test strip to the color chart. However, that’s all you get – you won’t get a complete water analysis as you would with a laboratory report.

Turnaround Time

DIY test kits are great if time if you need to test for fluoride as quickly as possible. You’ll get your results instantly – but, of course, they’re not 100% accurate.

Private laboratories take much longer to deliver your results. Some take up to three weeks – but we’ve featured labs that deliver results within four days.

🕵️ Our Research

In this section of the guide, we’ve shared how we chose and tested the different fluoride tests featured on our list.

📊 How We Chose

For this guide, we chose the tests on this list based on their testing accuracy, their customer feedback, and their value for money.

Testing Accuracy

Regardless of whether we were using a laboratory or a test strip, we prioritized accuracy. We conducted all of our tests on the same water sample, so it was easy to see when a certain test would deliver inaccurate results – they’d be different from the rest of the results we received.

We know that some people just want to know roughly how much fluoride their water contains, while others want to know their water’s exact fluoride concentrations. That’s why we’ve included options for at-home testing as well as laboratory testing in this guide.

Customer Feedback

Customer feedback doesn’t only tell you whether a product is worth your money; it also gives invaluable insight into a customer’s experience with the manufacturer itself.

We read hundreds of customer reviews when selecting the tests for this list. We ignored products with consistently negative reviews, knowing that the quality wouldn’t be satisfactory.

Is fluoride dangerous?

Low fluoride levels are considered harmless – and in fact, fluoride is great for dental health. Fluoride can strengthen teeth and prevent tooth decay. However, too much fluoride in drinking water may have negative effects on the tooth enamel, leading to dental fluorosis. Fluoride may also cause skeletal fluorosis and other adverse effects, including thyroid problems.

How can I reduce my daily fluoride exposure?

Drinking fluoridated water isn’t your only source of exposure to fluoride. Fluoride is also found in some foods, toothpastes, medications, bottled waters, coffees, and brewed teas. To reduce your daily fluoride intake, swap products containing fluoride for fluoride-free alternatives.

How can I remove fluoride from water?

The best way to remove fluoride from your water is with a suitable fluoride water filter. Reverse osmosis systems, activated alumina, and bone char carbon are good filters for removing fluoride. If you’re keen to learn more about your options, check out our best fluoride filters guide.

How can I test my water for fluoride from home?

You can test your water’s fluoride levels from home using a DIY test kit or an electronic fluoride meter.

What’s the cheapest way to test for fluoride in tap water?

The cheapest way to test for fluoride in municipal water supplies is with an at-home test strip kit. You can find at-home water tests for less than $30.

Are home water testing kits accurate?

Yes, home water tests are accurate – but only to some degree. While a home test strip kit can give you an understanding of whether your drinking water contains fluoride, it won’t tell you exactly how much fluoride is present.

Do water filters remove fluoride?

Some water filters remove fluoride, but not all do. If you want to remove fluoride from your city water supply, look for activated alumina, bone char carbon, or reverse osmosis filters.

How is fluoride measured in water?

Fluoride in tap water is measured in milligrams per liter (mg/L) or parts per million (PPM).

How much fluoride should my water contain?

To prevent tooth decay, the US Department of Health recommends 0.7 PPM of fluoride in drinking water. The maximum amount of fluoride in water, as required by the Environmental Protection Agency, is 4.0 PPM.
