Stelton’s Brus Magnesium+ 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. Magnesium helps enhance the taste of drinking water while adding minerals that support normal muscle and nervous system function. Designed specifically for the Stelton water filter jug, Brus Magnesium+ 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.
