Klarstein Replacement RO System Tap Water Filter, Reverse Osmosis Filter Improves Taste, Compatible with PuraFina 600 GPD, 24 Months Replacement Under-Sink Water Filter Cartridge, RO Membrane, 1 Pack

To ensure that clear, cold water continues to flow from your Klarstein PureFina 600 water filter system and stays clean and refreshing, you should regularly replace the Klarstein PureFina 600 RO filter. Depending on use, the filters last up to 24 months and tirelessly clean the water. To do this, they use the physical principle of reverse osmosis to filter impurities down to a millionth of a millimetre (0.0001 μm) from the water. As a comparison: A bacterium is about 3 μm in size and reliably gets stuck in the filter. The Klarstein PureFina 600 RO filter filters up to 600 GPD (2270 litres) of water per day.
