This cartridge is used to reduce fluoride by up to 90% for 1900 litres or 12 months*. This is achieved with treated aluminium ore which becomes porous and highly absorptive. The fluoride then bonds with the alumina and removes up to 90% when the filter is run at less than 4 litres per minute. For the most effective results, it is recommended that this cartridge is used as a pre-filter to a chemical reduction cartridge, such as a carbon or KDF-Carbon cartridge.

The cartridge life expectancy is an estimate only and is dependent on the quality of the water supply and the consumption rate.
