We did a water analysis before installing the filter. 3 indicators exceeded the norm, but most of all nitrates and they can only be reduced by reverse osmosis. This filter was bought on the advice of a colleague (she has the same one). The water analysis was repeated after installation, here are the numbers: hardness was 9 (normal up to 7) became 2. Calcium was 124 mg / l (it is not standardized) became 12. Nitrates from 162 mg / l (normal up to 45 mg) decreased to 64 mg. The kettle looks like new, no scale at all. I recommend the filter!
