The CB3 is the highest performance carbon block
cartridge on the market today. It is used in OMNI Undersink filters CBF3,
OT32, and OB3.
The CB3's carbon block removes chlorine and odors, harmful bacteria like Giardia
and Cryptosporidium, lead, and volatile organic compounds (VOCs) like Atrazine
(a herbicide) and Lindane (a pesticide), as well as 32 other VOCs, to give you
great tasting, safe drinking water right from the tap, or from a dedicated
faucet, depending on the unit selected.

If you receive a new model
and you are unable to close the top of your housing,
please remove the o-ring(s) from the new filter and use the ones from
the old filter, as the new ones may be thicker. This should allow you to
close the lid on the housing. If the new CB3 is too large to fit
in your unit, exchange for a smaller cartridge.
Because of the product’s limited service life and to
prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced
every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately.
Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
