I measured TDS in Hong Kong, TDS from a tap 370 ppm, TDS pouring clean water on the street (15 / 5l) 70 ppm, TDS atoll a-550em std 55 ppm. Measurements were taken by Xiaomi TDS Pen Pros below: Water quality. Equipment. Appearance. Ease of installation. The presence of a mineralizer. Tank 12 liters. Got cons: Of course, at the start you need to flush and spill the system. Takes a long time. 2 tank fillings (2 hours each). But this is a feature of the system.
