The 3-in-1 Active Soft Bag Filter removes chlorine, improves the taste of water, reduces water hardness and lime, ensuring a carefree drinking experience. Water quality is further enhanced as the fine filter fabric also retains heavy metals and residues from the pipes. The filter cartridge is reusable, and only the tea bag-like Active Soft Bag Filter needs to be replaced regularly. The filter capacity of one filter is sufficient for 100 liters of water or approximately 4 weeks. The set includes 3 filter bags.
