Tata swatch gravoty based water purifier is yhe cheap quality and one of the worst product. Build quality and designs are really questionable. When lower compartment fills completely with water and uppur compartment contains still not filtered water then water starts leaking from the middle of the product. Its due to design issue
between uppur and lower compartments. Purifying buld is placed inside the product which is not visiblee from outside, so if the bulb expires then we wont get to know whether purifier stoped working or not. The purifier can be used with borewell water bit not suitable for tap water. First two or three filters gives bad mud water. So the quality of the purifier is quastionable.
