The Berkey PF-4™ Element, or fluoride and arsenic reduction elements, work in conjunction with the Berkey Earth® DE Filter Elements to absorb unwanted elements found in drinking water. The Berkey PF-4™ Elements filters out fluoride, arsenic, and other heavy metal ions. The Berkey PF-4™ Element is made of non-leaching Polypropylene *5 and is BPA-free. The Berkey PF-4™ […]
The Super Sterasyl™ shell is primarily diatomaceous earth. The Granulated Activated Carbon (GAC) is actually made from carbonized coconut shell. Trace amounts of silver are included to prevent mitosis.
The Super Sterasyl™ Elements have been in continual use since 1827. This type of filter is known as a Super Sterasyl™ filter and is silver impregnated to inhibit bacterial growth. The Super Sterasyl™ filters have a lifespan of 535 gallons, before replacement is recommended. The British Berkefeld® system comes with a set of 7″ Super Sterasyl™ […]

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® purification elements, and the Berkey PF-4™ Elements that are […]
No, the unique ceramic filtering system reduces unhealthy organic chemical contaminants and impurities while leaving in most of the beneficial minerals your body needs.
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.
If the time it takes for the water to filter into the lower chamber substantially decreases, the flow rate can be easily renewed by cleaning the ceramic filter. Follow these simple steps: Carefully remove the Super Sterasyl™ Element from the upper chamber. Using a soft toothbrush or soft scouring pad (3M Scotch-Brite® or similar), scrub […]
The Super Sterasyl™ Ceramic Shell The Super Sterasyl™ grade ceramic is designed to remove suspended solids and pathogenic bacteria (>99.99%). The filter elements are produced using the latest ceramic techniques to provide a hollow porous ceramic, which is fired at a temperature in excess of 1,000º C. They are designed to operate with water flow going from […]
If you just purchased your Berkey® system and the filters are hardly filtering water, the problem is typically due to high water tension. This high water tension prevents the air from being purged from the micro pores of the new purification elements. Your Black Berkey™ elements need to be primed to purge this air out […]
