 Berkey PF-2 Fluoride Water Filter
     
  The Berkey fluoride water filter was developed to remove fluoride from your drinking water. Berkey developed this filter to adress the concerns of the many who find fluoride in drinking water unaccptable. Fluoride has been added to many municipal water supplies since the 1950's. This practice is now becoming controversial to say the least. New reports about the harmful effects of adding fluoride to drinking water are emerging. The benifits of applying fluoride directly to the surface of teeth are a well known. Fluoride that has been added to drinking water only comes in contact with the teeth for a very short amount of time and in a very diluted form. The body is than subject to the known ill effects of the fluoride compound for hours after ingestion. Critics claim that in this age of high fluoride tooth pastes that are applied to the tooth the benifits of fluoride in the water supply are negligent. Berkey fluoride water filter allows you to make the decision for yourself buy drastically reducing the amount of fluoride in your water.  
     
The Berkey PF-2™ Fluoride reduction filter elements are designed for use in all Berkey water filter systems in conjunction with the Black Berkey® water purification elements. In addition they also add the ability to adsorb the following unwanted elements found in drinking water.
  •  Fluoride
  • Arsenic V and pre-oxidized Arsenic III
  • Other residual heavy metal ions
  • MTBE

PF-2 Fluoride filterTECHNICAL INFORMATION:

FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent water solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the filter media (>95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).

ARSENIC: This filter product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.

REPLACEMENT:
Berkey Light with the fluoride filter attachedUnder normal conditions 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 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 is dependent on how much water You would use and 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 Berkey filter elements.

NOTES:

1) Do not boil the fluoride filter elements.

2) PF-2™ canisters reduce water filtering flow rate by 15-20%.
