CFS Carbon Block Water Filter Cartridges, 2.5 x 10 in, 5 Micron, Compatible with CB-25-1005, 4 Pack

CFS activated carbon block cartridges, 5 micron nominal, in the standard 2.5 by 10 inch size, four to a pack. A carbon block is powdered activated carbon pressed into a solid tube, so water has to pass through the carbon itself rather than around loose granules; that gives long contact time for reducing chlorine taste and odor and a tight enough structure to catch fine sediment at the same time. Fit it as the second stage after a sediment cartridge in a two stage housing, or as a single stage where the supply is already clear. A compatible replacement for the CB-25-1005 style carbon block and any standard 10 inch housing. Change about every three months or sooner if taste returns or flow drops. For cold water use only. Made by Complete Filtration Services as a compatible replacement, not an original manufacturer part.
