Fluoride is recommended by dentists for healthier teeth; however, some research suggests we may be exposed to too much as adults. That's why we have Berkey Fluoride filters to help reduce your fluoride consumption.
(Set of 2) Will last 1,000 Gallons or 10 Months (whichever comes first)
Berkey PF-2™ reduction elements are designed for use in conjunction with Black Berkey™ water purification elements to adsorb the following unwanted elements found in drinking water.
- Arsenic V and pre-oxidized Arsenic III
- Other residual heavy metal ions
Made from safe, non-leaching Polypropolene #5 that is BPA-free
It is recommended that each set of two Berkey PF-2™ fluoride water filters should be replaced after 1,000 gallons (3,785 liters). Example: If you had a Big Berkey system (2 gallon capacity) and you refilled the system 2 times per day, you would be using 4 gallons of water per day. Under these conditions the PF-2 fluoride water filter elements would last 250 days (1000 gal. divided by 4 = 250) or a little over 8 months. Actual replacement period for the PF-2 fluoride filter is dependent on how much water you would use and the presence of other competing contaminants in the source water. High levels of arsenic, fluoride and certain heavy metals may negatively affect the efficiency and capacity of the PF-2 elements.
