1
Influent challenge levels are average influent concentrations determined in surrogate qualification testing.
2
μg/L means Micrograms Per Liter.
3
Maximum product water level was not observed but was set at the detection limit of the analysis.
4
Maximum product level is set at a value determined in surrogate qualification testing.
5
Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point as determined in surrogate qualification testing.
6
The surrogate test results for heptachlor Epoxide demonstrated a 98% reduction. These data were used to calculate an upper occurrence concentration, which would produce a maximum product
water level at the MCL.

Testing was performed under standard laboratory conditions; actual performance may vary.
NOTE: Substances reduced are not necessarily in your water. Filter must be maintained according to manufacturer’s instructions, including replacement of filter cartridges.
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Systems certified for cyst
reduction may be used on disinfected waters that contain filterable cysts.
