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).
Length: 6 in.
Width: 2.5 in.
COLOR: WHITE REPLACEMENT: 6 MONTHS*
Under normal conditions it is recommended that PF-4 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.
