Stelton’s Brus Clear+ filter granules help reduce limescale, chlorine and possible heavy metals from tap water, making drinking water softer, cleaner and pleasantly neutral in taste. Filtered water also helps reduce limescale build-up in coffee makers and kettles. Designed specifically for the Stelton water filter jug, Brus Clear+ filter granules provide fast-flow water filtration. One pouch filters approximately 120 liters of water, and the granules should be replaced every four weeks. The pack includes three pouches of filter granules.
