How to filter fluoride from water


Australia and New Zealand are amongst the countries where fluoridation of the water supply is a measure taken in order to mass medicate its people. The intention behind adding fluoride to the water is to improve dental health amongst the population, first of all by reducing tooth decay. There is widespread criticism to this forced uptake of fluoridation, with claims of negative long term side effects, even though studies so far does not give conclusive evidence to support either side. Fluoridation of the water is common in prominent countries such as U.S.A, Australia and New Zealand, though the majority of European countries are united in opposing adding fluoride to the water supply.

Fluoride does not add any flavour, colour or fragrance to the drinking water, however, the chemical succeeds in spreading fear of potential harmful side effects, especially to the children. Some people fear that they will consume fluoride in excessive amounts by drinking large amounts of water as a result of physical exercise. What are the options available for the people living in countries with health care measures involving fluoridation? Besides moving to European countries, the options seem to be limited, as fluoride removal is notorious for being difficult to remove. This post will investigate different techniques and methods that have been proven to reduce or remove fluoride.

Water filters that remove fluoride

Most water filters do not remove fluoride, as it is an extremely difficult chemical to remove. Unless the filter specifications do not specify that it filters fluoride, they will most likely not be able to.

Reverse Osmosis Filters

Reverse osmosis filters are able to remove up to 99.95 % of fluoride, though the effectiveness depends on the different technologies implemented by the various brands. Some brands may only remove as little as 60% of the fluoride in the water. These filters tend to be quite large and requires a significant investment.

Carbon Filter

Some carbon filters, such as the advanced technology implemented by Fill2Pure, remove up to 90% of fluoride from the water. The filter technology offered by Fill2Pure is at the present the only portable fluoride water filter available on the market.

Water distillation

The process of distilling water is one other method of removing fluoride. Water distillation involves heating water until it boils and evaporates into steam, which is then transferred away from the heavy contaminants and chemicals left behind from the evaporation process. When the steam cools down, it transforms back into pure liquid water, having left the contaminants behind in a different chamber. Water distillation is without doubt effective in removing contaminants, although it is not an energy efficient method, with a substantial amount of energy needed to make the water evaporate. Additionally, water distillers can be quite costly as well as being of a significant size.


The best option for reducing intake of fluoride, besides moving to a different country is to invest in a carbon filter from Fill2Pure. You will still consume some fluoride, though at a much lower level than compared to drinking from the tap.
