Right now we know of only two test kits that the general public can make use of to test the fluoride content of their water: 1) National Testing Labs Fluoride Test Kit (mail-in); 2) eXact Micro 7+ Water Testing Meter (w/ fluoride reagent).

Why test for fluoride?

While many people in positions of authority believe fluoride a great additive for the public water supply, many others see it as a dangerous poison capable of doing massive damage to the population if no one monitors its levels.

Also, some people have severe, and sometimes fatal, allergic reactions to fluoride.

Moral of the story?

No matter what side of the fluoride Great Fluoride Debate you may find yourself, the fact remains that small amounts of fluoride can have beneficial effects on teeth and too much fluoride can harm a person over time.

Therefore, like any other water supply additives that serve a purpose (i.e. chlorine used to disinfect drinking water), we believe its concentration need to stay on the radar of water treatment operators at all times.

1. Bill wants to test the fluoride level in his water before it goes into his water filter. As awe have said time and time again, without a baseline scan of your water’s quality you will undoubtedly run the risk of selecting the incorrect tools for cleaning up your water.

2. Then, Bill wants to test the fluoride levels in the water after it leaves his water filter to make sure the filter did its job. Continual monitoring of one’s filtered water quality gives real-time performance data on one’s chosen water improvement device(s).

Enough of our words, though, and let’s here from Bill himself: “I am looking for a fluoride test–I am installing a filter to remove fluoride–and want to know what levelis presecn Please advise–the page on your website says to use the eXact Micro 7+ Water Testing Meter but the product description says nothing about it being used for fluoride”

None of us here at Water Testing Blog have control over the content posted on the sites of merchants who sell the eXact Micro 7+ water testing meter… but we can assure you that the meter does have the ability to test for fluoride in drinking water.

As a direct result of your inquiry, Bill, we checked on the meter manufacturer’s web site for the current version of the eXact Micro 7+ water testing meter manual and on page 19 of the document you will find instructions on how to use their meter to test fluoride levels in drinking water.

As of 8/17/11, the date contained in the manual’s file name, the eXact Micro 7+ detects levels of fluoride in water as low as 0.1 ppm and as high as 1.1 ppm. As with any test procedure, use of proper dilution techniques would allow for the quantification of higher fluoride levels if needed.

Keep in mind, though, that the basic eXact Micro 7+ kit does not come with the necessary fluoride reagent strips. You will find those, along with many other optional reagentstrips for testing a bunch of other water quality parameters listed on the eXact Micro 7+ ReagentStrip page.
