Why Remove Fluoride from Water?

Ok, so this is the subject of much debate. But many of you looking for a filter that gets rid of fluoride obviously already know that you don’t want it in your water and you most likely know why.

For those who happened here and are wondering why you would want to get rid of the fluoride that was purposely added to your water by your city, I will give a brief explanation.

The fluoride added to the city water in many communities, is mainly hydrofluorosilicic acid, (aka sodium fluoride) an industrial by-product from the phosphate fertilizer industry.

Studies that administered fluoride to rats concluded that the fluoride intake caused bone cancer and liver cancer in the rats. Cities that add fluoride to their water have higher rates of cavities and higher cancer death rates.

When Dr. Phyllis Mullenix, a neurotoxicologist, was appointed to study environmental toxins, she proved that fluoride is a neurotoxin that caused hyperactivity as well as memory and IQ problems in rats.

When children under 8 years old ingest fluoride over time, such as through drinking water and fluoridated toothpaste, it can cause dental fluorosis where their teeth get white flecks or streaks in them, and in extreme cases, the teeth end up getting pitted. It’s been noted that fluorosis can occur at 2 parts per million. Many water sources have higher levels than that.

Fluoride is a cumulative toxin. As it accumulates in the bones, it leads to skeletal fluorosis, which can be crippling, in adults and children. Skeletal fluorosis is preventable but there is no known cure. (If you decide to look up pictures of this… Be prepared! It can be quite upsetting)

Other symptoms of sodium fluoride toxicity:

  • Has been found to weaken the immune system
  • Has been found to damage the kidneys and liver
  • Fatigue, muscle pain, memory loss, insomnia
  • Increased thirst
  • Abdominal pain, nausea, and diarrhea

Fluoride, Thyroid Hormones and Metabolism

The thyroid gland releases hormones that control metabolism, which is the way our body uses energy.

It first absorbs iodine, combines it with the amino acid Tyrosine, and turns it into the thyroid hormones thyroxine (T4), and triiodothyronine (T3). T3 and T4 travel through the bloodstream and help every cell in our bodies regulate their metabolism.

Fluoride, chlorine, bromine, and iodine are all halogens. The problem is that the first three are toxic halogens that block the body’s iodine receptors so it can’t absorb the iodine that it needs. This can cause an increase of thyroid-stimulating hormone which can activate cancer cells and not just thyroid cancer but all hormone-related cancers.

The health of our thyroid is everything! Without proper thyroid function, our hormones will not function properly, in turn, our metabolism will not work and this is when anxiety can also come into play. It may seem like an indirect link from fluoride to the thyroid to anxiety but it’s actually a very common and well-documented problem. (Thyroid/Anxiety Connection)

For these reasons, I avoid getting extra fluoride in my drinking water by using an under-counter water filtration system. Specifically, a reverse osmosis filter that removes 95% of mercury (another toxin) and fluoride.

Review, Personal Experience, and General Info

I used to bring 4 – 5-gallon jugs down to the store a couple of times a week for my family of 4 in order to get reverse osmosis filtered water. That was a major pain!! We would run out and go down to the store at night and sometimes their machines would be down, then we would head to another store. I remember filling the jugs up at the dispenser outside of the grocery store in the pouring rain. The jugs were constantly sitting around the kitchen either waiting to be used or waiting to be re-filled and my back got tweaked out more than a few times from lugging them around.

Since we got the Aquasana under sink water filter I haven’t had to haul the 5-gallon jugs in and out of the house and car and it has definitely made things in the drinking water department easier for us.

I wanted the best water filter for fluoride removal but also a lot of other contaminants as I mentioned. I will discuss everything the Aquasana filters out later in this article.

I’ve looked at my city water quality report. I think my city does a good job of cleaning the water but it still tastes horrible for some reason and you can smell the chlorine in it.

Personally, even if I could get past the taste, I just don’t want to drink the chemicals, heavy metals, and other toxic contaminants in my city water. The city I live in adds fluoride to our water and there are also by-products that result from the chemicals they use to decontaminate the water. Some of these by-products are unregulated including Haloacetic acids or HAAs  – common undesirable by-products which result when chlorine-containing disinfectants interact with natural organic substances in the source water.

One proven way to decrease harmful HAAs is to remove them with a home water filtration system.

  • Purchase of the system includes your first set of filters


I personally haven’t had any negative experiences and when I looked at what other reviewers said most of them didn’t list any either.  A couple of people said it was difficult to install. However, many others like me listed “easy to install” as a benefit.

My husband is handy with things like this so we were able to work together to install it.

That being said, it can be frustrating working under the sink especially if you have a garbage disposal under there too which we do, it can get a little tight under there.

Aquasana recommends hiring a plumber because you have to drill into your pipes (see drilling at 5:43 on the installation video) to install the line, but as you can see on the video it’s really not a big deal.

We didn’t want to install the faucet up through our sink so we came up with the idea to mount the faucet on the inside of the cabinet door so when you open the door under our sink the faucet is mounted on it and we just use it from there.

      Best to you,


  2. At first, I thought, “Why would I want to get rid of fluoride that Was purposely added to water by one’s city?” I got really confused but I later understood why that needs to be done when I was reading this amazing article, it was very detailed and explanatory, I really enjoyed reading this article although it looks more of like a debate, I’m really glad I came across this article, to be honest, I will highly recommend it to my friends and family.

    1. Hi Jack,

      Thank you very much! I know what you mean, it is confusing. We always learn that it’s good for us and it’s good for our teeth but how many people know about fluorosis or how fluoride steals receptors meant for iodine?

      My best to you,


  3. US EPA maximum contamination limit for fluoride in drinking water is set at 4.0 mg/L. You can remove the fluoride from the water you’re drinking by using one of the fluoride water filters featured in this article by a reputable brand that has proven to deliver their claims on their products. Thanks for putting this through.

    1. You’re welcome Joshua, thank you very much for your thoughts and adding to the discussion.

      My best to you,
