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.

RO30 with AS3, TD
These systems have been tested and certified by NSF International according to
NSF/ANSI 42, 53, and 58 for the reduction of the substances listed below. 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 NSF/ANSI 42, 53, and 58.
This system is acceptable for treatment of influent concentrations of no more than 27 mg/L
nitrate and 3 mg/L nitrite in combination measured as N and is certified for nitrate/nitrite
reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater.
