Please note: These elements have a different threading size to the Berkey PF-2's and PF-4 will not fit Berkey Black filters. 

The Berkey PF-4 use an inert form of activated alumina for the adsorption of the following four unwanted elements commonly found in drinking water. For gravity units these have been the most tested filters and for customer who may have a medical condition and need the best fluoride removal for gravity filter units. These are used with our 15L ceramic Billabong Benchtop Water Purifiers.

*Fluoride(both natural fluoride and substance added to your water supply
*MTBE (Methyl-tertiary-butyl-ether)

PF-2™ elements are also designed to "adsorb": *Heavy Metal Ions *Herbicides and *Pesticides
*DBCP (Dibromo-cholro-propane)
*THMs (trihalomethanes)

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

Berkey PF-4™ reduction elements, are designed for use with Doulton Ceramic Filter candles.

Independent lab testing reveals how Berkey PF-4™ Fluoride and Arsenic Reduction Elements perform over time. Look at the first column to see the volume tested, and the last for the % fluoride reduction. It is critical to have multiple samples in order to determine the rate of “% Reduction” drop-off, and by association, the lifespan of the element.
