Our PF-2 filters reduce fluoride and arsenic in your water using the media aluminum oxide (aka activated alumina). As a consumer, it’s important to know that pure aluminum and aluminum oxide have vastly different characteristics. Pure aluminum is water-soluble, it is highly reactive and it is associated with negative health effects. By contrast aluminum oxide […]

I noticed that the PF-4™ elements also remove MTBE and heavy metals. Should I use these with my Black Berkey® Elements?
No, the PF2™ is used in conjunction with the Black Berkey® Elements and the PF-4™ elements are used in conjunction with the ceramic filters. The Black Berkey® Elements remove MTBE and reduce heavy metals whereas the ceramic filters do not therefore; we incorporated MTBE and heavy metals reduction capabilities into the PF-4™ elements.
What are the dimensions of the Berkey PF-2™ and Berkey PF-4™ Elements?
The individual elements are 6” in length and 2.5” in diameter. The side of the Berkey PF-2™ Elements that attaches to the Black Berkey® Elements is 11mm.
I installed my Berkey PF-2™ Elements but my water is a bit cloudy and why does it have a funny taste?
The odd taste is from process dust that may not have been washed free from the filter elements during the priming process. Please remove the PF-2™ elements and re-prime them for 60 seconds on both ends. It may be necessary to repeat the priming process up to ten times to expel all the residual process […]
What is the life of the Berkey PF-2™ Elements?
Each set of two Berkey PF-2™ Elements will last for approximately 1,000 gallons of water.
Do the Berkey PF-2™ Elements replace the Black Berkey® Elements?
No the Black Berkey® Elements fit into the base of the upper chamber with the threaded stems of the filters protruding through the holes in the base of the upper chamber. The PF-2™ filters screw onto these threaded stems so that the Berkey PF-2™’ Elements hang down into the interior of the lower chamber. The […]
Do your Black Berkey® Elements and Super Sterasyl™ Elements reduce fluoride in the water?
No, in order to reduce fluoride in your water, you will still need to use post filters that work in conjunction with the filters in your system. We have two types of post filters: the Berkey PF-2™ Elements which are used in conjunction with the Black Berkey® Elements, and the Berkey PF-4™ Elements that are […]
Do the Berkey Light® systems contain BPA?
In the past the Berkey Light® systems were made of food grade polycarbonate that was approved by the US Food and Drug Administration. Some research suggests that polycarbonates have been known to leach BPA (Bisphenol-A) when either exposed to High Strength Industrial Grade Alkaline Detergents or when they are repeatedly exposed to temperatures in excess of […]
Do the Super Sterasyl™ Elements remove beneficial minerals?
No, the unique ceramic filtering system reduces unhealthy organic chemical contaminants and impurities while leaving in most of the beneficial minerals your body needs.
How do I determine when the Super Sterasyl™ Element must be replaced?
Replace the elements when the carbon has been exhausted or if there is a significant change in diameter of the ceramic after cleaning. Anytime a crack in the ceramic occurs, the integrity has been lost and the filter must be replaced.
