These filter elements are designed to reduce fluorides in drinking water to below 0.5 ppm.
They are constructed with materials which are FDA approved. The A-2 filter element uses activated alumina that has been especially
prepared for the reduction of fluorides in drinking water. Laboratory tests show that this preparation will improve the capability of
the filter to reduce the fluoride levels from 10 ppm F+ to below 0.2 ppm F+. Normal total capacity of the A-2 is over 8,000 ppm F+.
Capacity 1900 Litres - should be replaced annually
