Berkey PF-2 Fluoride and Arsenic Reduction Elements (Pack of 2)

Effective Contaminant Reduction: The PF-2 elements effectively reduce fluoride (including sodium fluoride, sodium fluorosilicate, and fluorosilicic acid), arsenic V, pre-oxidized arsenic III, and other residual heavy metal ions. High Reduction Rates: Under optimal conditions, these filters can achieve fluoride reduction rates of over 95%, with effluent concentrations of less than 50 ppb, equating to a reduction of more than 99.75%. Durable and Safe Materials: Constructed from BPA-free, non-leaching Polypropylene #5, ensuring safety and longevity. Long-Lasting Performance: Each set of two PF-2 elements has a lifespan of approximately 1,000 gallons (3,785 liters) or up to one year, depending on water quality and usage.
