I have never used any product as horrible as a Kent water Purifier. Service is pathetic. Right after the purchase I have been facing problems after problem and I had to even escalate the matter to their CEO to get a proper response. They did service it and make it work for some time but it never lasted for long and I had to call them for one or other issues frequently. Until warranty period it did not cost me much but soon after the warranty period, they started levying exorbitant charges for replacement of filters, UV bulb and what note. I wonder if there is any part in the Kent Purifier that would last for even 2 years! Except the outer casing, there isn’t any! Strongly recommend to keep away from any Kent Products.
