Berkey PF-2 Fluoride Filters

The filters remove the following from your drinking water: - Fluoride - Arsenic: V and pre-oxidised Arsenic III - Other residual heavy metal ions Bear in mind that the flow rate is reduced by 15 to 20%! Attach the filters to the bottom of your Black Berkey filters. You do this by removing the blue protection with clean hands. You can then screw them onto the other filters. Just make sure you have as many Black Berkey filters as fluoride filters. We recommend replacing the filters at around normal conditions, so 3785 litres. This of course depends on the contaminants in the water. *This product is sold in pairs.
