The Hobart 01-234301-97200 carbon block water filter is a single-pack replacement cartridge designed to remove chlorine, sediment, and unpleasant tastes or odors from water supplies. It works by directing water through a compressed activated carbon block that captures fine particles and chemical contaminants as water flows through the filter media. This process helps deliver cleaner water to connected equipment while limiting scale and residue buildup on internal components. Benefits include better water clarity, improved taste and odor control, protection of valves and fittings, and easy replacement during routine service, making it a practical solution for maintaining reliable performance .
