Berkey Replacement Element - Ceramic & PF-4


This listing and the price above is for any of the Two (Ceramic or Earth or PF4 filters )--- you may choose multiple filters using the dropdown menu above.
*** Please note Berkey PF-4 Fluoride Arsenic FITS CERAMIC Filters Only, this not for Black Berkey Elements ***

The Sterasyl™ Ceramic Shell

The 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 the outside to the inside of the element. The ceramic shell exhibits a strictly controlled pore structure, so as to provide efficient sub-micron filtration, a proven defense against hard-shelled parasites such as Cryptosporidium as well as pathogenic bacteria. The ceramic also removes other less harmful, but equally unpleasant particulate debris such as rust and dirt.
The composition of the Sterasyl™ ceramic contains silver. This silver is a material designed to significantly inhibit mitosis or grow through. The result is that bacterial growth is inhibited from occurring within the Sterasyl™ ceramic element (which is possible with the other ceramic filter elements). Because of the silver, Sterasyl™ filter elements do not require sterilization after cleaning.

The Sterasyl™ filter, when used in in-line housings, is certified by the National Sanitation Foundation (NSF) as meeting their Standard No 42 for materials.


The Super Sterasyl™ Water Filtration Element

The Sterasyl™ ceramic is the ceramic shell used for the Super Sterasyl™ filter element. Accordingly, this filter element will have, at a minimum, the filtration benefits of the Sterasyl™ ceramic. Additionally, the bore of the ceramic shell is filled with granular activated carbon, which enables the filter to reduce chlorine and organic chemicals while improving the color, taste, and odor of the source water. The re-cleanable Super Sterasyl™ filter elements remove suspended solids, parasites, cysts and pathogenic bacteria (>99.99%) and reduce organic chemicals, pesticides, herbicides, organic solvents, trihalomethanes, SOCs, VOCs and foul tastes and odors. The top of the Super Sterasyl™ element is closed with a unique ceramic dome. This prevents the possibility of breeching (leakage), which can occur with filtration elements that are closed with a plastic cap.

What’s Hiding in Your Drinking Water? Super Sterasyl™ Filters:

Pesticides, herbicides, organic solvents, SOCs, VOCs, trihalomethanes.

Reduce Chlorine > 90%

Reduce Turbidity, Sediment and Particulate:

@ 0.9 micron > 99.99%
@ 0.5 – 0.8 micron > 99.9%
@ 0.2 – 0.3 micron > 98%
(based on tests by Spectrum Laboratories, Minneapolis, MN).

Maximum working pressure: 125 psi
Maximum working temperature: 100º F
Minimum working temperature: 40º F

Super Sterasyl™ ceramic filters are manufactured to the following international standards and have been tested and approved by the following independent bodies or agencies:


Berkey PF-4 Fluoride Arsenic FITS CERAMIC Filters Only - 2-pack K5350 - Not For Black Berkey Elements


Designed to be used as a post filter to remove or reduce fluoride, lead, arsenic, and mtbe. These are used in conjunction with ceramic filters, and screw onto the bottom threads. For use with gravity filter systems such as the big berkey and british berkefeld systems that use white ceramic filters. Not for use with black berkey filters. Technical specifications: mtbe: the pf-4 is manufactured to exceed ansi/nsf standard 53 which requires that mtbe be reduced by at least two thirds from an influent rate (water going in) of 15ppb to an effluent rate (water going out) of less than 5ppb (> 95% reduction*). Lead: tests have shown that when 2000 gallon (7, 600 liters) of influent water at a concentration of lead of 200 ppb pass through 200 grams of media at a flow rate of 1 gpm (3. 8 lpm), the lead level was reduced to less than 1ppb (>99% reduction). 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 95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99. 75% reduction). Replacement: under normal conditions it ismended that pf-4 elements be replaced at six-month intervals (actual capacity is dependent on the presence ofpeting contaminants in the source water. High levels of total organic carbons, volatilepounds or certain inorganic minerals may reduce the capacity and efficiency of these elements. )


Earth Element :

The most powerful gravity-fed element in the Filtration class, backed by independent testing Filtration class: Micro-Filtration Technology. Tested to reduce contaminants to bacterial level Chemicals, herbicides, pesticides, VOC’s, THM’s, heavy metals and more are easily reduced to 99.9% Proprietary formula comprised of Diatomaceous Earth, granulated activated carbon and other media components, designed to exceed filtration standards Each Berkey Earth® Filration Element will filter up to 3,000 gallons of water or last up to 3 years, before replacement is needed. With 4 elements (in a Big Berkey® system), the 7” elements can produce flow rate of up to .8 gallons per hour or up to 19 gallons of water in 24 hours Ideal for the price-conscious consumer to get started with a highly efficient filter system, at a more affordable price Economical entry price affords those who would like to upgrade to the more powerful Black Berkey® Purification Elements down the road, the ability to get an effective and economical system now and then upgrade later Available in 7” and 9” sizes Compatible with BerkeyPF-4™ Fluoride and Arsenic Reduction Elements
