Filter Refill from Swedish Aarke is specially created for the water filtration jug Aarke Purifier. These are filter granules that the brand has developed in collaboration with one of the world's leading companies in water technology – BWT. The filter granules lift ordinary tap water and provide an even better taste experience. They come in two different varieties, Pure and Enriched. Pure reduces unwanted substances and transforms tap water into a cleaner taste experience. The filtered water is ideal for carbonation or to brew a perfect cup of coffee or tea. Enriched reduces unwanted substances, adds magnesium and converts tap water into alkaline water.
