Questions on Black Berkey Filters (2)

• From Leslie Garby at 8/3/12 12:09 PM
  • Do the black berkeys remove salt from the water?
  • Hi Leslie -
    
    No, salt is considered a beneficial mineral, so they do not remove salt from the water.
    
    Thanks

  • Will this filter remove fluoride?
    
    
  • Hi Brad -
    
    No, you would need the add-on PF-2 filters that go in the lower chamber of the berkey systems. These are offered at a discounted price with the purchase of a system.
    
    Thanks

  • What exactly are these filters made of?
  • Hi Jpatti -
    
    From our FAQ - Without getting too complex, several methodologies are utilized by the Black Berkey purification elements. The elements are composed of a proprietary formulation of more than a half dozen different media types constructed into a very fine matrix creating millions of micro-fine pores. The pores are so small that pathogenic bacteria, cysts, parasites, sediment and sedimentary minerals are not able to pass through them. The media formulation both "absorbs" some contaminates and "adsorbs" other contaminates. Next, heavy metals ions (mineral molecules) are extracted through an Ion exchange process where they are essentially electrically bonded to the media. Finally, our filter elements are designed such that each water molecule can take several minutes to pass through the filter elements whereas these molecules passing through other filtration systems pass through those filters in literally microseconds. The longer the water molecules are in contact with any media, the greater the removal of the various contaminates.
    
    Thanks

  • What is the difference in the black berkey filters and the white ones? We bought our Big Berkey a few years back and it came with white filters.. Also I need to know how long the filters can be kept unused and still be useable.. Thank you for the information. Gail
  • Hi Gail -
    
    That question can be answered with this article we put together that compares the 2 types of filters. Let us know if you need anything else.

  • If unused, do the Black Berkey Filters have a shelf life?
  • Hi Scott -
    
    The shelf life is indefinite as long as they are not exposed to high heat (over 120 degrees), or freezing temperatures.

  • Do the replacement filters come with the washer and wingnut or do I need to order a replacement kit as well? Thanks.

• From Kami at 1/12/13 3:24 PM
  • If I have 4 black filters does that mean the approximate lifetime for that set of 4 being used at the same time is 12 000 gallons?
    Thank you
  • Hi Kami -
    
    Yes, that is correct.
    
    Thanks

• From richard Fugo at 2/10/13 2:32 AM
  • how do you install the filtres to the water line?
  • Hi Richard -
    
    The filters do not install into a water line, and only work with our countertop gravity filtration systems.
    
    Thanks

• From Louis at 2/24/13 12:53 AM
  • I live near a brackish water or briny water supply. It is not as high in salinity as sea water but is still too high to drink. Would these filters filter water with high salinity to a safe level?
  • Hi Louis -
    
    No, the filters do not remove beneficial minerals from the water, and salt is one of these minerals. So, the brackish water would remain the same. Let us know if you have any other questions.
    
    Thanks

• From jane at 3/18/13 8:23 PM
  • Precisely how does the pf 2 remove FLUORIDE from the driink water???
  • Hi Jane -
    
    The media that is used inside the PF-2 filters adsorbs the fluoride and the water that passes over these granules.
    
    Thanks
