I don’t like this Ro .In starting time this RO give a best service but in present time the water is not like a mineral water .The purify water come from RO like a simple water . The RO is not sufficient to give a good quality mineral water .when I was call customer care no the two person came from company and service the RO machine but after 1 month the RO is like a machine which gives a simple water and create a very high sound .I recommended please check and then buy this product. In my reference this product is waste of money and waste of time.
