PF-4™ MTBE, Fluoride, Lead, Arsenic Reduction Elements

4 Element Price: $80.00 8 Element Price: $145.00

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).
