Water Filtration System Data
IMPORTANT NOTICE: Read this Performance Data Sheet carefully 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 system has been tested according to NSF/ANSI 42, 53, and 401 for 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 401.
9030868 cartridge certified by IAPMO R&T in system 9030868-SYS against NSF/ANSI standards 42, 53, and
401 for the reduction of the claims specified on the Performance Data Sheet; against NSF/ANSI 372 for low
lead content; against CSA B483.1.
SPECIAL NOTES
• Replacement Sub-Zero water filters can be ordered online at subzero.com/store,
or contact Sub-Zero Customer Care at 800-222-7820.
• It is recommended that the filter be replaced when the indicator appears, if
there is a noticeable drop in pressure, the ice cubes become hollow, or every 12
months, whichever comes first. Replacement filter pricing information can be
found at subzero.com/store.
• This filter must be installed, operated, maintained, and replaced as required in
order for the product to perform as advertised.
• Note that while the testing was performed under standard laboratory conditions,
actual performance may vary. The contaminants or other substances removed
or reduced by this water treatment system are not necessarily in your water.
