Boshart Industries icemaker/in-line taste and odor cartridges utilize coconut shell granular activated carbon and are designed to remove unpleasant tastes and odors as well as sediment to produce cleaner, clearer, better tasting water. They have a low pressure drop, high dirt holding capacity, durable physical strength and steady flow to achieve reliable performance and long life usage. By packing the carbon the concerns of shifting carbon inside the filter are removed. These Granular Activated Carbon filters are easily installed on the water line to an automatic icemaker, reverse osmosis system or water dispensing system.
