Klarstein Replacement RO System Tap Water Filter, Reverse Osmosis Filter Improves Taste, Compatible with PureLine 400 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 PureLine 400 water filter system and refreshes you cleanly and refreshingly, you should regularly replace the Klarstein PureLine 400 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 PureLine 400 RO filter filters up to 400 GPD (1500 litres) of water per day.
