Under Sink Water Filter - Model CBF3

Model CBF3 uses the leading carbon block technology to remove lead, Giardia and Cryptosporidium cysts, and volatile organic compounds (VOCs), including Atrazine (an herbicide) and Lindane (a pesticide), from your drinking water. The carbon block filter cartridge is also great at removing chlorine and odors so you get great tasting water from a dedicated faucet right in the sink.
Included with Model CBF3 Filter System is:   
installation hardware, a long-reach dedicated faucet, pressure release valve, wrench, mounting bracket, saddle valve, and a CB3 filter cartridge.
CB3 filter cartridge, K4 O-ring and OW30 Wrench.  
Additional cartridges and parts sold separately.   
Change CB3 filter every 4 months. Change tank O-ring with every 3rd filter cartridge change.
