PF-4 reduction elements are designed for use in conjunction
with the white Super Sterasyl Elements for the Berkey series of water
filters to adsorb the following four unwanted elements most commonly found
in drinking water.
• MTBE (Methyl-tertiary-butyl-ether)
• Fluoride
• Lead
• Arsenic
PF-4 filters are also designed to adsorb:
• DBCP (Dibromo-chloro-propane)
• THMs (trihalomethanes)
• Herbicides & Pesticides
• Heavy Metal ions
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 of influent water at a concentration
of lead of 150-200 ppb pass through 200 grams of media at a flow rate
of 1gpm, the lead level was reduced to less than 1ppb (>99% reduction).
FLOURIDE: 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 per cubic
foot of media. Results of < 1ppm of the fluoride ion in the effluent
were typical for the media (>95% reduction). Under optimum conditions,
effluent concentrations of less than 50 ppb were readily achieved (>99.75%
reduction).
