The
Good Water Machine
models listed above have been tested according to ANSI/NSF Standard 58 for effective
reduction of TDS, arsenic, barium, cadmium, hexavalent and trivalent chromium, copper, cysts, fluoride, lead, radium
226/228 and selenium as verified and substantiated by test data. The concentration of the indicated substances in water
entering the system was reduced to a concentration less than or equal to the permissible limit for water leaving the
system as specified in ANSI/NSF 58.

1. While testing was performed under standard laboratory conditions, actual performance may vary depending on water pressures, temperatures, and
other substances, which may be found in your water.
2. This system shall only be used for arsenic reduction on chlorinated water supplies containing detectable residual free chlorine.
3. Nitrate units are not certified for nitrate/nitrite reduction in water supplies with a pressure less than 4 psi (280 kPa). A booster pump is strongly
recommended.
4. Based upon testing methods using Barium as a surrogate. All concentrations in pCi.l: pico cutirs/L.
5. United States Environmental Protection Agency (USEPA) Safe Drinking Water Act.
6. Includes Giardia, Lamblia, Entamoeba Histolyca and Cryptosporidium.
