The innovative Pure Advantage filter technology, not only gives you clean filtered water faster than ever before, it also makes your tap water taste great. Filtering tap water is practical because it gives full use of the water that you already have at home. Pure Advantage™ Filtration Technology: the unique and innovative filter contains 3M purification technology which removes impurities, odour and unpleasant tastes from tap water to provide clean, healthier water for you and your family. It filters tap water in 4 steps: pre-filtration, ion exchange filtration, activated carbon filtration and final filtration. Each filter achieves a filter capacity of approximately 150 litres of tap water and should be regularly changed (after 30 days) for optimal performance. Ultra Fast Flow Pure Advantage filter technology provides high quality filtration, and filters 2x faster than traditional water filtration jugs. It takes approximately 2 minutes to filter 1 litre of water, meaning less time waiting for filter water, and more time for you. Great Taste: The Pure Advantage™ filter technology removes odours and particles that affect smell and taste such as chlorine and organic impurities. Using filtered water when cooking improves the taste of your food and enhances the flavour and appearance of tea and coffee. Improves Lifetime of Kitchen Appliances: The filter reduces the build up of limescale (carbonate hardness) which prolongs the lifetime and performance of your kitchen appliances. Tested and Certified The Pure Advantage filter has been tested and certified by the independent German test institute TÜV Rheinland and LGA. This pack contains 6 replacement Pure Advantage™ water filter cartridges for Aqua Sense water filter jugs.
