AS3
The AS3 has been tested according to NSF/ANSI 53 for the reduction of the substances
listed below. The concentration of the indicated substances in the 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 NSF/ANSI 53. Conforms to NSF/ANSI Standard 53 for
arsenic (trivalent and pentavalent) reduction. See Arsenic Fact section for an explanation
of reduction performance.

1 While testing was performed under standard laboratory conditions, actual performance may vary depending on water pressure, temperatures and
other substances, which may be found in your water.
2 This system has been tested for the treatment of water containing pentavalent arsenic (also known as As(V), As(+5) or arsenate) at concentrations
of 0.050 mg/L or less. This system reduces pentavalent arsenic, but may not remove other forms of arsenic. This system is to be used on water
supplies containing a detectable free chlorine residual at the system inlet or on water supplies that have been demonstrated to contain only pen-
tavalent arsenic. Treatment with chloramines (combined chlorine) is not sufcient to ensure complete conversion of trivalent arsenic to pentavalent
arsenic. Please see the Arsenic Facts Sheet for further information.
3 Based upon testing methods using Barium as a surrogate. All concentrations in pCi/L pico curie/L.
4 Includes Giardia lamblia, Entamoeba histolyca and Cryptosporidium.
5 Units are not certied on water supplies with a pressure less than 40 psi (280 kPa). A booster pump is strongly recommended.
