Berkey Fluoride Filters (PF-2)
PF-2 Fluoride and Arsenic Reduction Filters adsorb the following unwanted elements found in drinking water:
- Fluoride: Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid (aka Hydrofluorosilic Acid)
- Arsenic: V and pre-oxidized Arsenic III
- Other residual heavy metal ions
Replacement: Set of 2 PF-2 Filters need replacement after 1000 gallons of use. As an example, The Royal Berkey system is about 3.25 gallons and therefore the filters should be replaced after 307 (1,000/3.25 ) refills. Or in other words, If the system is refilled about one time per day they should be replaced after 10 months, if the system is refilled about twice per day they should be replaced about every 5 months.
Warranty: The Berkey PF-2™ Fluoride and Arsenic Reduction Elements are covered under a six month warranty
