RO-6-BF and RO-6-BF-NF
This system has been tested according to NSF/ANSI 58 for reduction of the substances 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 58.

Note:
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 0.30 or less. This system reduces pentavalent arsenic but may not
remove other forms of arsenic. For arsenic removal, 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 tested to contain only
pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to ensure the complete
conversion of trivalent arsenic to pentavalent arsenic. Please see the arsenic facts section on page 20 of this
manual for further information.
