How to Remove Fluoride from Water for Free(Proven Methods)

Most people just do not pay enough attention to this ubiquitous compound found in our water supply.

Fluoride is the name given to the ionized form of the element fluorine and its naturally found in abundance in water and soil.

Fact is, fluoride that is used toothpaste and mouthwash helps in remineralizing the tooth enamel, preventing cavities and tooth decay.

However, when you drink water with large doses of fluoride, there are potential side effects that you can experience.

Some of these are dental fluorosis, skeletal fluorosis, Low IQ in scores in children between 10-12 years, joint and muscle pain – all can result in over-exposure to this compound.

So, what is the solution? How can you effectively remove excess levels of fluoride from water effectively and at a reason cost?

In this post we’ll look into;

  • How to Remove Fluoride Using Holy Basil
  • How to remove fluoride using other means.

How to Remove Fluoride Using Holy Basil

how to remove fluoride from water

Holy basil, also known as tulsi, is naturally your best bet for removing Fluoride from water and for free.

You simply add a bunch of the leaves and stems (dried or fresh) to a container of water, wait 8 hours while they do their magic and then strain out the leaves.

Using this method will decontaminate approximately 5 gallons of water from fluoride.

While you can use more, the added benefits of using more are nearly non-existent and result in a waste of plant material more than anything else.

The general guidelines suggest using roughly 80mg of plant material for every 100ml of water.

While this method is effective at removing Fluoride, the wait time may be longer than what most people would wait before the water is free from fluoride

So if you intend on using holy basil to filter off fluoride, the earlier you start, the better.

Let it rest overnight and then shake it vigorously, in the morning you will have fluoride free water

This way, you can avoid drinking any high concentration of fluoride.

How to Remove Fluoride using C. Japonica (Sugar Cane)

Sugar cane is a close relative of grass, but comes with the added benefit of being able to remove fluoride from water.

When sugar cane leaves are placed in water with fluoride, the plant can remove up to 40% of fluoride from drinking water. It’s simple, easy and affordable.

Sugar cane plants are effective in the removal of fluoride from water, mainly because of its ability to exude large amounts of roots and produce biosorbents.

You start by fermenting sugar cane and adding it to water, and this removes up to 4 mg F/L (EPA and USP standards).

A study was conducted to investigate the ability of sugar cane plant (Saccharum spontaneum L.) to remove fluoride from water by using plants grown in the presence of 4 mg F/L.

In their presence, 4 mg F/L was removed from distilled water in a 4-day period.

The results showed that there were high significant differences between control and treatment at P< 0.05.

How to Remove Fluoride using Reverse Osmosis

Reverse Osmosis works by pushing highly pressurized water through a semi-permeable membrane filter with a fine pore structure, effectively removing minerals and contaminants including fluoride.

Reverse Osmosis may be capable of filtering out more than 99% of most contaminants and trapping larger particles.

However, anything with a molecular weight less than or equal to the weight of the water might slip through

The biggest problem with reverse osmosis systems is the fact they also remove the healthy and beneficial minerals that our body needs regularly.

Trace minerals such as magnesium, iron, sodium, calcium, and potassium are examples of trace minerals that are removed. 

How to Remove Flouride using Carbon Water Filters

Carbon filters are recognized as being the best technology available in removing both organic and synthetic chemicals from tap water.

As an added benefit, carbon filters do not remove the natural trace minerals in tap water as reverse osmosis does.

These systems contain blended media, which include carbon–with a sub-micron pore structure, and ion exchange for filtering out synthetic chemicals, chlorine, and chlorine byproducts. 

These units come with a standard activated granular carbon filter for removing chlorine and a few other chemicals, but those also armed with a multi-block feature will remove any fluoride present.

The activated carbon filter works by giving these contaminants a charge so they are absorbed and removed

The EPA recognizes carbon as the best choice available for filtering a variety of chemicals, including the problem of pharmaceutical drugs in the water supply as well as Cryptosporidium and Giardia cysts.

Carbon-based filtration systems come in many varieties. There are points-of-use carbon filters and whole house carbon filters.

The whole house activated carbon filters will remove the most common chemicals found in tap water including harsh disinfectants which are added to sanitize city tap water.

The water filters will list the contaminants they are capable of removing as part of their capabilities. Sometimes, people settle for the pitchers and faucet filters which are a point of use carbon filters when seeking a lower-cost alternative to bottled water.

However, such filters are typically less effective than whole house water filters.

So there you have it. Whenever you are looking for a device or method for filtering chlorine for your household water, make sure it not only removes chlorine but also removes synthetic chemicals and other contaminants.
