Do water filters remove fluoride?

You might have come across various discussions around fluoride removal and fluoride water filters. There is a debate that constantly exists on the benefits of consuming fluoride, especially for stronger teeth, and on the contrary why fluoride exposure is harmful. Fluoride in drinking water is not always helpful and investing in water filters to reduce fluoride exposure is suggested.

In this article, we will discuss in brief the healthy fluoride levels and if water filters remove fluoride, and the types of water filters that assist fluoride reduction in tap water and drinking water.

The basics of fluoride

Before we understand how water filters remove fluoride, it is important to know what is fluoride.

The basics of fluoride

Fluoride is nothing but a naturally occurring mineral. This mineral is present in rocks and is released from them into the water, air, and soil. Almost all water is fluoridated water. Studies prove that fluoride exposure in healthy amounts is necessary to have strong bones and teeth. Fluoridated tap water and drinking water can help to prevent tooth decay.

In some cases, water fluoridation might be required with the fluoride amounts being very minimal. Larger quantities of fluoride are also not healthy, which can lead to dental fluorosis, weakening of bones, and even other health problems. In this scenario, fluoride reduction becomes the need of the hour. Here is where you have to make use of fluoride water filters to reduce fluoride exposure.

As aforementioned, there are ongoing controversies on consuming fluoride and whether it is safe for drinking purposes among the other contaminants. Rather than removing fluoride like other unwanted contaminants, there are some states that have fluoridation programs.

In a fluoridation program, rather than treating fluoride content as contaminated water, this water is added with fluorine. Fluoridated water is considered safe for dental hygiene and to get stronger teeth. Drinking fluoridated water from a young age can be associated with strong teeth and even help to prevent tooth decay.

Although this does not mean you can drink fluoridated water in excess amounts. On a thin line, fluoride in drinking water can also lead to dental fluorosis, increased skeletal fluorosis, lead to thyroid problems. Excess of fluoride in drinking water can affect human health in the long run. If you have been drinking fluoridated water, you must make sure it is within the right measure. Remember, you cannot drink fluoridated water in large amounts which can cause a severe impact on human health.

Do water filters remove fluoride: 

The common question among customers when it comes to fluoride in drinking water is; do water filters remove fluoride and how can a water filter remove fluoride? Here is what you need to know about water filters and fluoride water filters.

Do water filters remove fluoride:

Water filters are large and are specially designed equipment to remove contaminants from drinking water. Tap water or drinking water can have plenty of unwanted contaminants, right from bacteria, algae, microbes, and other contaminants. Contaminated water can also have a high dose of heavy metals. Tap water especially that is loaded with heavy metals is not safe for drinking. To purify this contaminated water, filters remove contaminants through a series of processes. The manner in which the heavy metals or other contaminants are removed will depend on the type of water filter.

When it comes to fluoride removal we must know that it is a challenge. All water filters are not capable of removing fluoride. However, to help a water filter remove fluoride with up to 95% effectiveness, there are special designs and techniques available.

Which water filter removes the most fluoride?

Let us take a detailed look at how water filters remove fluoride. The following are the popular types of water filters to remove fluoride with effectiveness.

Activated alumina filters

An activated alumina filter is the most effective and popular choice for fluoride removal even at home. Using activated alumina filters can guarantee the removal of fluoride from drinking water with an effectiveness of 95%.

Activated alumina filters

The activated alumina filter media is made using aluminum oxide. This aluminum oxide in the media alumina filters ensures the removal of fluoride and arsenic only. Unlike most filters that target several contaminants, this aluminum oxide filtration system has only these two minerals as its focus.

 You must also note that filter systems that use activated alumina filters for filtering water are capable of removing traces of other harmful contaminates. This has been proven to improve the water taste after filtering water. Keep a watch for most filters that make use of activated carbon media. A close watch can make sure you find the best alumina media for filtering water inside of the carbon media.

Bone char filters

The other ideal activated carbon filter is bone char. 90 to 95% of fluoride in drinking water can be removed by this highly porous carbon filter. It is not common to find bone char filters. However, the exceptional ability of the bone char carbon filter in fluoride removal deserves appreciation.

Bone char filters

Bone char carbon filters can remove fluoride, radionuclides, volatile organic compounds, and even heavy metals which are not easily filtered otherwise. This capacity makes bone char carbon filter an ideal choice to remove fluoride in drinking water.

You must note that activated carbon filters are quite different from bone char carbon filters. Each of these implies different chemical reactions to remove fluoride from drinking water.

Reverse osmosis systems

A reverse osmosis system is another famous water filtration system that has been a trusted company for several years to filter water. Filtered water from RO systems has a special preference. An advanced and fully working RO system can filter fluoride from tap water or drinking water up to 95%. You might find that most RO systems are installed at him as under-sink water filters.

RO systems, the popular choice as under-sink water filters are built with a semi-permeable membrane that is designed to be a carbon filter as well as a sediment filter. Here, the reverse osmosis filter is the member that will remove fluoride. The reverse osmosis filter will function as a string barrier against all contaminants.

Reverse osmosis systems

The advantage of reverse osmosis filters is that they do not remove fluoride alone. Reverse osmosis filters remove other harmful contaminants and impurities in drinking water as well, especially those that affect the water’s taste and smell.

There are disadvantaged to using the RO system. Most RO systems are expensive, almost all of them. Consistent maintenance and repairs of reverse osmosis systems are costly. Additionally, a RO water filter system will remove even the healthy minerals that are essential in drinking water. Removal of these healthy minerals in this water filter system affects not just affects the water taste, but also the pH and quality of the drinking water.
