ABOUT THE FILTER CARTRIDGE
Filter Cartridge Replacement
You should change your filter when the water flow is noticeably reduced or at least every 3 months.
Replacement Filter Cartridges
Several variables determine how long the cartridge will
last in your Household Water Filtration Housing. These
include:
■ levels of sediment or other undesirable substances in
your water.
■ the amount of water you use.
■ the filter location (filtering all or part of your
household water).

was reduced to a concentration less than or equal to the permissible limit
for water leaving the system, as specified in NSF/ANSI 42. While testing
was performed under standard laboratory conditions, actual performance
may vary.
