I had purchased this purifier one year ago. It is worth Rs 13, 500 and had one year warranty. This was latest available models and many things were promised while purchasing it. But after a year none of the things were accomplished. Also it had three times free servicing in a year. But I kept calling to the service Centre and nobody came for repairing within a year. Apart from this the purifier is not working properly from the day one. As internal of the purifier needs cleaning from service Centre, thus the taste of water is degraded. Also when switched on, it makes disturbing noise. Also the purifier are of low standards and the service one should get is not appropriate. I suggest not to buy this purifier as at the same price one can get good purifier.
