Fluoride occurs in nature. The concentration of fluorides is greater in volcanic or mountainous areas and it is also found in traceable amounts in the water, air, flora and fauna. Fluoride defines a group of compounds that contains fluorine. Fluorine can exists as a compound that is extremely dangerous to our health such as in its sarin form, or it can be utilised as a beneficial pharmaceutical as with toothpaste.
Many water authorities use a form of fluorine to treat the public water supply so to reduce the levels of tooth decay in the population. This is normal accomplished by using one of the three compounds, Sodium fluoride, Fluorosilic acid or sodium fluorosilicate. The recommend amount of fluorine range from 0.7 to 1.2 mg/L (equivalent to parts per million). However, Fluoride is recognised by the World Health Organisation as a possible contaminant that should be monitored by their water testers.
Excess fluorine causes Skeletal Fluorosis. Although half of the Fluoride is filtered and excreted by the kidneys the excess attaches to your skeletal system. The fluoride interferes with the regeneration of bone, a process called remodelling. Bone remodelling is a lifelong process where mature bone tissue is removed from the skeleton and new bone tissue is formed. The attachment of fluoride onto the bones interfere with this process making the bones weaker and less resilient.
Most European countries stopped treating public water fluoride in the 1970s. Fluoridation of the water supply is controversial. However, it is still being used in Australia. Fluoride is difficult to remove from the water supply. Its removal can only be achieved through Reverse Osmosis and Distillation methods.
Great Water Filters recommend that you check out the Elite Series 3 Reverse Osmosis system. This product has a reverse osmosis membrane that has a micron size so small that it can remove fluoride.
