Horrible experience with this machine, substandard, water taste bad, first repair of UV light was required within a month of purchase. subsequent multiple repairs in a year. there are no membrane to remove dust particles, so when the open machine each time for repair, you can actually see sand accumulated at the end of the storage container. they say that no AMC required but needed to change the CSF ( purifying part) twice within a year. 1000/-expenditure each time. so it is same expenditure as other product. don’t even think about buying it. Go for standard companies.
