I compared the quality of water from my parents - from a tap, a filter jug, drinking water from a store and drinking water from a terminal (a filter system was installed at the house). The terminal turned out to be the best option - industrial filters do their job. The other three differed from each other, but ppm changed by 10 percent: from the tap 407 ppm, filter jug - 390, store drinking - 360. Water from the terminal - 020 (20 ppm). So the device provides all the necessary information for making decisions.
