I bought this purifier for my home few months ago. Im still using it. But it has too many problems. It was getting problem every 20 days. The engineer visits my house every time as I request and does something which I totally cant understand. One thing I understand is that he temporarily fixes the problem and the problem comes again and again. The engineer once came for repairing and he did everything in rush and also broke my water pipe which I fixed later calling a plumber. The service is not at all fulfilling. Just search another brand for buying water purifier.
