7. Troubleshooting
Understanding TDS Readings
A high Total Dissolved Solids (TDS) reading is not necessarily an indication of a poor filter. The Waterdrop Ultra Filtration system is designed to retain beneficial minerals in the water, which contribute to the TDS reading. Therefore, it is normal and expected for filtered water to still show a TDS reading, even comparable to bottled mineral water.
