Cartridge CB6
The CB6 is a carbon block cartridge for OMNI's heavy duty Whole House water filter, Model BF7. In addition to filtering rust and sediment, it removes odors, chlorine, and bacteria such as Giardia and Cryptosporidium. With a CB6 filter cartridge in your Model BF7 water filter, not only is the water from every faucet (including hot water faucets) in your house safer to drink, it also tastes better!
