Performance Data Sheet
Model WHED20 Drinking Water Filter
IMPORTANT NOTICE: Read this Performance Data Sheet and compare the capabilities of this unit with your actual water treatment
needs. It is recommended that, before purchasing a water treatment unit, you have your water supply tested to determine your actual water
treatment needs. This filter system is designed to be used for the reduction of the performance claims listed below. Do not use where
water 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 water that may contain filterable cysts. While testing was performed under standard laboratory
conditions, actual performance of the system may vary based on local water conditions. Some or all of the contaminants reduced by this unit may not be in your water
supply. See Use and Care Manual for further instructions on filter cartridge replacement, system installation, operating procedures, and warranty. The
maintenance instructions must be followed for the product to perform as indicated below.

1Influent challenge levels are average influent concentrations determined in surrogate qualification testing.
2µg/L means Micrograms Per Liter.
3Maximum product water level was not observed but was set at the detection limit of the analysis.
4Maximum product level is set at a value determined in surrogate qualification testing.
5Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point as determined in surrogate qualification testing.
6The 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.
