FILTER CARTRIDGE REPLACEMENT
The life of the cartridge depends on the water volume used and the
substances in the water. Normally the cartridge should be changed at
intervals of 90 days or less. Replace it sooner if the water pressure at the
faucet begins to drop noticeably or if you notice changes in the taste,
color, or flow of the filtered water.
NOTICE: Certain types of harmless bacteria will attack cellulose material.
Cartridges containing cellulose, such as TO1 and RS1, may seem to
disintegrate, produce a “sewer” or “rotten egg” odor, or form a
black precipitate due to bacteria. If this happens, consult OMNIFILTER
Customer Service for advice.
