Berkey PF-4™ Fluoride Arsenic Reduction Elements

 

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

*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

 

Sold in sets of 2
Berkey PF elements contain inert high-grade activated alumina; an efficient way for reducing fluoride from drinking water.

PF-4® (Flow K 5350) Reduction Elements absorb (remove):

  • > 95% Fluoride
  • Lead, Arsenic, MTBE, DBCP, THMs, Herbicides, Pesticides and Heavy Metal Ions

PF-4® and PF-2® elements are identical in their function. The only difference is that PF-4® elements are needed for use with Super sterasyl filters, while PF-2® elements are required for Black Berkey® filters.

 

 

Technical Information:

Please note: These filter elements have a specific threading size that will only fit to ceramic Doulton® and British Berkefeld® Filters. If you are unsure which system you need to use, please contact us.

Berkey PF-4® reduction elements, are designed for use with Doulton ceramic filtration elements to absorb the following four unwanted elements most commonly found in drinking water.

MTBE (Methyl-tertiary-butyl-ether)
Fluoride
Lead
Arsenic

Berkey PF-4™ filters are also designed to absorb:

DBCP (Dibromo-chloro-propane)
THMs (trihalomethanes)
Herbicides & Pesticides
Heavy Metal ions

Beyond the use of 3785L the Berky PF-4 elements will no longer reduce the fluoride levels in the water.

  • 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 (11 lpm) 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.
  • Lead: Tests have shown that when 7,500 litres of influent water at a concentration of lead of 150-200 ppb pass through 200 grams of media at a flow rate of 1gpm, the lead level was reduced to less than 1ppb (99% reduction).
  • MTBE (Methyl-tertiary-butyl-ether): Berkey PF elements are manufactured to exceed ANSI/NSF standard 53, which requires MTBE be reduced by at least two thirds from an influent rate (water going out) of less than 5ppb (>95% reduction*)
    *Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of total organic carbons and volatile organic compounds may reduce the capacity and efficiency of the elements.

 

Replacement:

Under normal conditions it is recommended that each PF element be replaced after 1,000 litres or 6 months — whichever comes first. If you consume about 5 litres of filtered water a day, you would need to replace it every 6 months in a system using 1 ceramic filter and 1 element at a time.
If using more than one PF element at once it is recommended to change both of them every 6 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.

 

INSTALLATION PROCEDURE
Berkey PF-4® elements must be washed and primed before USE

PRIMING PROCEDURE

The media in your Berkey PF-4® contains micro fine process dust that can cause the filtered water to have a bitter taste. To dislodge the process dust from your element, it is necessary to prime each element. To prime your element use the following procedure:

  1. With blue caps in place wash the exterior of each element with mild dish soap
  2. With clean hands, remove both blue caps from the end of each element.
  3. Place the rubber washer (priming button) onto one of the elements and align the hole in the button with the hole in the element. Hold on to your priming button for further priming.
  4. Press the priming button up against a sink faucet so that the priming button creates a seal between the faucet and the PF-4® element.
  5. While holding priming button against faucet (place thumb on top of faucet to apply pressure and create a better seal) Turn on the cold water gently, allowing water to fill the cavity of the PF-4®element and discharge for at least 20 seconds or until water runs clear whichever is longer.
  6. Turn the PF-4® element the other direction and prime the other end repeating steps 3-5. The element has now been primed.
  7. Repeat the above steps with the second PF-4® element.

 

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

  1. fast shipping!

  2. great to add these to the berkey earth filters
    fluoride is very harmful and after watching a video yesterday on it
    i decided to hop on and purchase these

  3. Great price on original filters.

  4. We use a lot of water so i needed more of these!

  5. does what it supposed to do

  6. Great Filters!

  7. love these filters, they go well with my ceramic filters and take out the chlorine taste!

  8. Lovely filters! fit greatly on my crown berkey
