Filter Cartridge Replacement
Taste and Odor Cartridges:
A taste and odor cartridge contains activated carbon, a black powder.
When new, open the filtered water faucet and allow fine, carbon particles to purge from the cartridge.
Close the faucet when you no longer see the “fines” (carbon particulates) in the filtered water, or approxi-
mately 10 minutes.It is recommended to replace the filter cartridges every six months of use. There are
several variables that determine how long a cartridge will last. These include:
1. How much water you use, and
2. 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 notice the return of the unwanted substance in your water.
