PF-4® (Flow K 5350) Reduction Elements absorb (remove):
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.
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.
Berkey PF-4™ filters are also designed to absorb:
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.
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.
Berkey PF-4® elements must be washed and primed before USE
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:
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.
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
