The Pure Kit includes the Aarke Purifier and 4 filter refill bags of Pure Filter Granules, which is equivalent to 4 months' worth of filter refills. Enjoy softer, cleaner, better-tasting tap water for months. The granules are poured into the refillable filter cartridge and make your tap water cleaner and more pleasurable by reducing limescale, chlorine and heavy metals (lead and copper).
