Quick Answer
The Prestige Tattva 2.1 CU ST is a must-buy if you rely on low-TDS municipal water and want antimicrobial copper storage benefits without electricity costs. While its 9 L/hr flow rate is efficient for small families, it is not designed for borewell water. This model excels in urban flats prioritizing natural filtration.
Choose the Tattva 2.1 CU ST for maintenance-free purification and copper enrichment if your TDS is below 200 ppm. Avoid this gravity filter if you face heavy sediment or hardness levels that require active RO technology for safety.
