These cartridges are highly effective at removing unwanted bad taste & odor and other contaminants, providing you with great tasting, safe water right from the tap.

The CB1 cartridges fit all 10" Standard Housing and can replace any 10" x 2.5" carbon filter. They are NSF INTERNATIONAL tested and certified for your peace of mind.
