I am a dietician by profession and I am very concerned rather particular about the water I drink or the food I eat. I always pay extra attention to my diet.So frankly speaking spending Rs.17000 on water purifier really did not really give me a heartache. So I invested money on Kent Grand Plus, which was a real good investment I must say because it provides me 4 step purified water which is real healthy thing.We should always ensure twice to thrice about the water we drink or the food we intake. So I always pay more attention to the purification details of the eatables. This water purifier is suitable for water from all sources such as bore-wells, overhead storage tanks, water tankers and even municipal taps. The elegant design with transparent cover makes it a visual pleasure. The purified water level indicator Double Purification by RO & UV with TDS controller. This is a computer controlled operation with filter change alarm.UV Fail Alarm is audible. The purifier does not function until the UV lamp is replaced to ensure the delivery of only 100% pure waterFully automatic operation with auto-start and auto-offAfter a pre-set time, Filter Change Alarm is audible which indicates time to replace the filters.
