Cartridge CB3
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.

Need Help? Please call our customer service number: (888) 855-3545 for assistance. 
Change cartridge filter every 6 months.
