The reverse osmosis filter is the gold standard in water purification. It forces water through an ultra-fine membrane—blocking anything larger than 0.001 microns. That means heavy metals, minerals, organic compounds, and bacteria don’t stand a chance.
Engineered to deliver up to 7,200 liters of pure water, it’ll last two years with average daily use of 10 liters. The K690’s built-in indicator lets you know exactly when it’s time to replace the filter. Installing a new filter takes just 10 seconds.
