A genuine BRITA replacement filter cartridge for the BRITA Purity C Steam 500 Water Filter System. Proven technology re-invented for small to mid-sized steamers and ovens. The BRITA PURITY C Steam Filter Cartridges, specially developed for small to medium-sized combi steamers and ovens, reduce carbonate hardness in drinking water and, as a result, prevent limescale formation in equipment. In addition, the Filter medium retains metal ions such as lead or copper and reduces substances, for example chlorine, that can negatively affect taste and aroma.
