Does a Water Ionizer Remove Fluoride?

Over the years, many countries have been adding fluoride to their public water supply, including the United States. It all started when scientists discovered that people who lived in areas with prevalent natural fluorides had fewer cavities. But now, eliminating this fluoride from water has proven to be an uphill task for many. And this triggers the question, does a water ionizer remove fluoride?

Alkaline water ionizer removes fluoride from water. However, the amount of fluoride a particular water ionizer can eliminate depends on how robust the ionizer is and the type of filter it uses. Besides, there is a specific pre-filter designed to get rid of fluoride.

What are Water Ionizers and Water Ionizer Pre-Filters?

You can also refer to a water ionizer as an alkaline ionizer. It is a home appliance that increases water PH through electrolysis. A water ionizer splits the incoming water flow into alkaline and acidic components.

The alkaline stream is what you refer to as alkaline water. Like alkaline diets, many people claim that consumption of this water yields many health benefits. But there is no proven medical evidence to support these health benefit claims.

Originally, the water ionizer machine started to function in Japan and East Asian countries before spreading to Europe and the United States.

Unlike coffee machines, an alkaline water ionizer, which works as a water electrolyzer, siphons off the water that is close to the cathode. The siphoned water on the cathode side contains high hydroxide and PH levels, making it alkaline water.

On the other hand, siphoned water on the anode side contains high H+ levels, thus acidic. Claims show that you can use acidic water for household disinfection.

A water ionizer pre-filter refers to the additional filter you add to your water ionizer system. You have to attach the filter to your ionizer’s water supply. That way, it can filter the incoming water before it gets to the water ionizer.

Not all filters remove fluoride from water. Therefore, when making your purchases, remember to request a pre-filter that gets rid of fluorides.

Here is the best whole-house water ionizer to buy:

Bluevua RO100ROPOT Reverse Osmosis System Countertop Water Filter

Key Features

  • 1700 Milliliters capacity

Filters have a lifespan of 12 to 24 months thus saving you money as you enjoy drinking safe and clean water for up to 2 years.

Some of the Best Filters for Fluorides

You can only treat fluoride with specific filter types. Avoid a filter that is not detailed for fluoride reduction. To make your buying process easier, here are some of the best options to look out for:

1. Reverse Osmosis – It is one of the best methods to use because it eliminates almost all the fluorides from your water. However, you can only make a few water gallons at a time with it.

2. KDF filterThe filter is one of the best in the market. It is ideal for those people who live in agricultural areas. That’s because it yields water with high hydrogen sulfide levels.

3. Charged Modified Composite BlendWith this filter, you get maximum protection against fluoride. Besides, it is also very effective in getting rid of toxins and heavy metals like hexavalent chromium 6.

4. Life Arsenic Filter – If you are dealing with high fluoride levels, a life arsenic filter is what you need. Life arsenic is effective against both lead and fluoride. The filter uses special media to shield you from heavy metals.

How to Choose the Best Filter for Your Water Ionizer

To acquire the best water ionizer filter, do the following:

1. Get a Water Report Copy from Your Local Municipal

You cannot buy a water ionizer filter if you don’t know what is in your water. The first step you need to take is to get your municipal water report. The local water authority files this report every year. It details all the contaminants found in the water after analysis.

2. Determine the Filter Size and Quality

Depending on your water ionizer type, choose the most effective filter size. Trusted sources show that longer cartridges give you the best filtration compared to shorter ones. But don’t forget to specify if you need a filter to remove fluoride.

3. Check the Price

When it comes to filters, spend more on quality. Cheap inferior filters may only put your health at risk.

How to Remove Fluoride with an Electric Water Ionizer

Basically, fluoride is acidic. An electric water ionizer splits incoming water into alkaline and acidic components. Therefore, the ionizer diverts the fluoride into the acidic water stream.

However, the fluoride amount your ionizer removes depends on the flow rate and the water ionizer setting. Generally, an electric water ionizer can eliminate about 85% or more fluoride amounts from the water.

Besides, water ionizers differ in their filtration systems. Some are more effective than others, with the ability to remove up to 99.99% of fluoride from water.

How to Remove Fluoride with the Non-Electric Water Ionizer

The technology behind these non-electric water ionizers is unique. First, these non-electric water ionizers get rid of natural minerals in the water. After that, they add magnesium to eliminate the fluoride.

I advise that you always confirm from the manufacturer if the water ionizer of choice removes fluoride before buying. That way, you can avoid disappointments.

Again, I recommend you attach an extra fluoride pre-filter cartridge to your water ionizer for excellent results.

Frequently Asked Questions (FAQs)

Q. Do all water filters remove fluoride?

A. Not all water filters are capable of filtering fluorine. For instance, a refrigerator water filter does not get rid of fluoride. The best option is the use of a reverse osmosis system.

Q. Which is the best water ionizer on the market?

A. The Bawell Platinum Water Ionizer (pictured), is an exceptional water ionizer that gives you purified drinking water. Alongside that, you get both acidic and alkaline water. You install the water ionizer under the counter to enable a sleek sprout above your counter.

Q. What are the best ways to remove fluoride from water?

A. The most affordable and effective method is distillation. Other effective methods are reverse osmosis, water ionizers, Activated Alumina, and Bone Char Carbon.

Q. Do water ionizers remove chlorine?

A. Majority of water ionizers have GAC (granular activated carbon) filters. These filters reduce heavy metals, chlorine levels, and other chemicals.

Q. Will boiling water remove fluoride?

A. Boiling water may rid off chlorine, but not fluoride levels. In fact, boiling the water may raise the fluoride content further.

Q. Is fluoride bad for you?

A. Excessive fluoride consumption can harm your health.  Children are the most affected and face the risk of dental fluorosis. Fluoride accumulation also makes bones fragile and can be fractured easily.

Final Thoughts

Many have been asking, does a water ionizer remove fluoride? But I believe this article has helped answer that question. Water ionizers are effective in eliminating fluoride. However, always remember to visit the product page to see whether the ionizer of choice works against fluoride.
