The Enriched Filter Granules are our upgraded, mineralisation filter option. On top of making your water cleaner and tastier by reducing chlorine and heavy metals, it adds magnesium mineral to support the function of muscles and turns your tap water into alkaline water through increased pH value. Made exclusively for the Aarke Purifier technology, the granules in the bag are poured into the Purifiers refillable water filter cartridge. The granules are sold in a 3-pack of refill bags equivalent to 3 filter cartridge refills. One bag filters up to 120 liters of water and lasts up to 4 weeks. Made in collaboration with BWT, one of the worlds leading water technology companies.
