The Aquasana reduces fluoride by 40-60%.

There are 5 isotopes which make up fluoride and the Aquasana will remove two of the isotopes with the ion-exchange technology. This reduces the influent levels to approx. 0.5 ppm.

All research showing negative effects has shown levels above 1 ppm.

Some water filters which remove fluoride contain alumina as their filter media, which is not recommended because fluoride has a strong affinity for aluminum, forming aluminum fluoride. It ‘tricks’ the body into thinking it is a hydrogen atom, allowing it access across the blood-brain barrier. . Research has shown a link between aluminum fluoride and kidney damage as well as brain cell damage, such as lesions in the brain similar to those found in Alzheimer’s and other forms of dementia.

Which 2 isotopes from fluoride are removed and what information do you have on them?

Calcium fluoride: Also known as mineral fluorospar (fluorine – semi precious gemstone) which is found in nature as a solid and is insoluble in water. It is commonly used as a window and lens material, in the manufacture of Teflon and in the separation and concentration of uranium isotopes in nuclear reactors.

Sodium fluoride: A colourless crystalline salt used in the fluoridation of water, toothpaste, as an insecticide and rat poison. According to Hazard Identification Data it is listed as toxic if swallowed or inhaled and affects the respiratory system, heart, skeleton, circulatory system and kidneys. Long term exposure may cause mottling of teeth and brittle bones (fluorosis), weight loss, anaemia, calcified ligaments, general ill- health and joint stiffness.
