I had bought this purifier 1 year back. I bought it under 15k which is nominal price to spend on water. I just thought if it could success. Fortunately I liked the service. Very good pH value of water. I had got it tested in lab and it is really pure. They provide free maintenance for 2 years also. The filters also dont cost much. It is bearable. This was suggested by one of my friends who is also an old user of this RO. So overall this is a nice pack for being healthy. Now my whole family is based on this to drink safe water.
