FILTER CARTRIDGE LIFE
Several variables determine how long a cartridge wilt
last These include:
1. how much water' you use
2. how much sediment, taste and/or odor', or other un-
wanted substance, is in the water'
Use the following information as a guide. However;
no matter' which type of cartridge you are using, you
will know it is time to replace it when you first no-
tice the return of the unwanted substance in your
water.
Sediment Cartridges: Average cartridge life, when
filtering water to 1 faucet, is about 6 months This aver-
age time varies depending on the type of' sediment
caruidge.

the cartridge wizen water pressure to the faucet drops
Taste and Odor Cartridges: Filtering water to a
single faucet, the filter cartridge may last fbr 6 months
or' more If the cartridge is also for' lead or chemical
contaminant removal, it is more important to replace
it frequently.
