Berkey PF-4™ Fluoride And Arsenic Reduction Elements

 

The PF-4™ Fluoride and Arsenic Reduction Filters are made and assembled in the USA

  • PF-4 Fluoride and Arsenic Reduction Filters adsorb the following unwanted elements found in drinking water:
    • Fluoride
    • Arsenic
    • Lead
    • Heavy Metal Ions
    • MTBE (Methyl-tertiary-butyl-ether)
    • Trihalomethanes (THM)
    • DBCP (Dibromo-chloro-propane)
    • Herbicides and Pesticides
  • Made from safe, non-leaching Polypropolene #5 that is BPA-free
  • Sold in a set of 2
  • PF-4 Fluoride and Arsenic Reduction Filters are designed to be used in conjunction with the Berkey Earth® Elements or the Super Sterasyl™ Ceramic Filter Elements
  • Attach to the bottom of the Berkey Earth®  Elements or the Super Sterasyl™ Ceramic Filter Elements and sit in the lower chamber of the Berkey unit
  • Number of PF-4s in the bottom chamber must match the number of Berkey Earth® Elements or Super Sterasyl™ Ceramic Filter Elements in the top chamber; for example, 2 Berkey Earth® Elements would require 2 PF-4 Filters
  • PF-4 Filters need replacement after six months

 

The PF-4 is for use with Berkey Ceramic Filters – If you use Black Berkey filters, you will need the PF-2 *** PF-4 reduction elements are designed for use in conjunction with Berkey Ceramic Filters to adsorb the following unwanted elements found in drinking water. Fluoride, Arsenic V and pre oxidized Arsenic III, Other residual heavy metal ions. FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (99.75% reduction). ARSENIC: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations. REPLACEMENT: Under normal conditions it is recommended that each set of two PF-4 elements be replaced after 1,000 gallons.

Berkey PF-4™Fluoride and Arsenic Reduction Elements for the Berkey Earth® Filters or Ceramic Filters

INSTALLATION and USE:
*Assemble the water filter as per system assembly instruction.

*On the underside of the upper chamber (holding the ceramic filter/ filters), locate the stem of each ceramic filter, making sure the wing nut of the filter is in place and hand tightened.

*With clean hands take a primed (caution read directions above “priming procedure”, before installing) PF-4® element , with the water flow arrow pointing away from the upper chamber. Screw the PF-4® on the protruding thread of the ceramic filter 3-5 revolutions.

 

DO NOT SCREW MORE THAN 5 REVOLUTIONS OR YOU MAY CAUSE DAMAGE TO THE INTERNAL SCREEN.

*When complete, seat the upper chamber on top of the lower chamber. Fill upper reservoir or container.

* When the lower reservoir is full, discard the first batch of water, which may contain some process dust.

*When upper chamber is full of water the PF-4 will be immersed in the stored water area.

 

How Activated Alumina Works

Activated Alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square meters/gram. The compound is used as a filter of fluoride, arsenic and selenium in drinking water.

One of the effects of using this filter medium is that it may leach some aluminium in the water even though it removes the fluoride.

So when using Activated Alumina, you should always get at least a two-stage water filter. The second stage will contain a form of activated carbon that can take care of any aluminium problem
