I bought Kent RO 8 years back for Rs. 15000/- . The filters of this RO is very costly and so is the RO I can not afford costly RO but for the sake of the family health I prefer for the best in the market. but when I came to know that the filter of RO is also costly then I feel trapped because in market there are other ROs are less than KENT and of good quality. Instead of changing costly RO filter I switched to Phillips RO of Rs. 5000/- and it working fine. I think KENT should reduce their price .
