The Berkey PF-4TM Fluoride and Arsenic reduction elements are designed for use with the 7 Inch Long Mount Doulton Super SterasylTM and the Doulton ATC Super SterasylTM ceramic filtration elements which are used in the Doulton SS Gravity Water Filter Systems.

The PF-4 filters adsorb the following four unwanted elements most commonly found in drinking water.

Reduces:

– MTBE (Methyl-tertiary-butyl-ether)
– Fluoride
– Lead
– Arsenic

PF-4TM filters are also designed to adsorb:

– DBCP (Dibromo-chloro-propane)
– THMs (trihalomethanes)
– Herbicides & Pesticides
– Heavy Metal ions
Under normal conditions it is recommended that PF-4TM elements be replaced at six-month intervals (Actual capacity is dependent on the presence of other competing contaminants in the source water. High levels of total organic carbons, volatile organic compounds or certain inorganic minerals may reduce the capacity and efficiency of these elements.)*. Note: do not boil this element.

The PF-4TM 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 150-200 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).
Can be used with the Doulton/British Berkefeld Stainless Steel Gravity Systems
Reduces fluoride >95% Reduction
Lasts at least 6 months
