Understanding Water Purification and the Limits of TDS in Assessing Water Quality
Water purifiers with multiple filtration stages use different filters like RO, UV, UF, sediment, and carbon to address various impurities based on water source and quality. Total Dissolved Solids (TDS) levels are commonly checked but do not fully indicate water safety, as contaminants like bacteria, heavy metals, fluoride, nitrate, and arsenic may be present. Experts advise testing beyond TDS to ensure water safety, considering seasonal changes and specific local water conditions when choosing purification methods.
