FILTER CARTRIDGE / USEFUL LIFE / REPLACEMENT
FILTER CARTRIDGE LIFE
Several variables determine how long a cartridge will last. These include:
1. where the water filter is installed (filtering all house water, or just to one faucet)
2.how much water you use
3.how much sediment, taste and/or odor, or other
unwanted 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-
rice the return of the unwanted substance in your
water or a substantial reduction in flow.
Other filter cartridges are available from Sears to
remove (1) sediments, (2) tastes and odors, (3) tastes,
odors and chemical contaminants, and (4) tastes, odors and lead.
Many bad tastes and / or odors are removed from wa-
ter by an activated carbon cartridge. It is most often used to remove chlorine taste and smell, usually to a single faucet such as the kitchen cold.

sand, silt, clay, dirt, and other sediments from water.
The 25 micron cartridge filters larger sediments from
water, and allows higher flows at less pressure drop.
The 5 micron cartridge filters finer sediments from
water, usually to a single faucet. Cartridge life, when
filtering water to one faucet, is about 6 months maxi-
mum. Cartridge life is less when filtering all house
water. This time varies depending on the type of sed- iment cartridge.
for lead or chemical contaminant removal it is more
important to replace it frequently.
Note: Small amounts of hydrogen sulfide (noticeable
as "rotten egg" odor) may be reduced by taste and
odor filters for a short time, quickly exhausting the
carbon media. Consult your Sears store for proper
continuous treatment.
Sears has several taste and odor filter cartridges
available. These filters are used to filter the water to
one faucet and are not intended for whole house
filtration. These are:

reduction, plus chemical contaminants
To filter sediments from all house water, locate the
water filter housing on the main water supply pipe.
Please ask your Sears associate about products that
will remove taste and odors from your water
throughout the home. You can also filter water to
one faucet. For example, install the filter under the
kitchen sink to filter the cold drinking water. Typical- ly taste and odor flIters are installed to fiIter water to one
faucet only. Refer to the following drawings.

FILTERING WATER TO ONE FAUCET
When filtering sediments you will know it's time to
replace the cartridge when water pressure drops to the single faucet, or to the entire house supply.
Filtering water to a single faucet, the filter cartridge
may last for 6 months or more. Cartridge life is less
when filtering all house water. If the cartridge is also
