This point-of-use (POU) high-flow carbon block filter reduces bad taste, odors, and extra fine sediment. Removes particles as small as 0.5 microns. Due to the fine micron size of this filter, the use of one or more pre-filters is highly recommended to avoid premature clogging. Ideal for use as a replacement filter for under sink or under counter filter units. Filter size: 2-7/8″ x 9-3/4″. Fits most standard 10″ housings.
