Carbon Block

Shop carbon block water filter cartridges for drinking water, reverse osmosis, and whole-house filter housings. Carbon block media is commonly used to reduce chlorine taste and odor and may target additional contaminants when specifically rated. Compare cartridge size, micron rating, media, capacity, flow rate, certifications, and housing compatibility to select the right replacement.
