Berkey Fluoride Filter - PF-2 Arsenic and Fluoride Filters
Berkey Fluoride Filters For Your Home
The Berkey Fluoride Filter, also known as PF-2's, go in the lower chamber of the berkey system and have been designed to remove fluoride from your tap water.
Consider these findings:
"PF-2 fluoride filters are designed for use in conjunction with Black Berkey water purification elements to adsorb the following unwanted elements found in drinking water:
Fluoride Removal up to 99.75%
Arsenic V and pre-oxidized Arsenic III
Other residual heavy metal ions
Under normal conditions it is recommended that each set of 2 PF-2 Berkey fluoride filters be replaced after 1,000 gallons. The Royal Berkey system is about 3.25 gallons therefore the PF-2 filters should be replaced after 1,000/3.25 or 307 refills. If the system is refilled about one time per day, the PF-2's should be replaced after 10 months, if the system is refilled about twice per day, the PF-2's should be replaced about every five months). Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of Fluoride, arsenic and heavy metals may reduce the capacity and efficiency of the elements."
