Review on Filter under the sink Aquaphor OSMO 50 version 5 by Micha Kumicki ᠌

I have been looking for a divider for a long time. According to the instructions, you need to first check for its presence. It turns out that it is already installed in the cartridge tube coming out of the filter into the drain. The total volume of the tank is slightly more than 5 liters, not 8. Filtering these 5 liters takes 50 liters to the drain. Cleans water very well. TDS meter reading on tap water 437 ppm, after filter 26 ppm. There is no more scale in the kettle. I don't like the taste of water, it's kind of sterile. So I think a separate mineralizer will change it?
