VERY VERY High Maintenance Cost, Its almost 5000 Per Year.Clearly HUL is cheating, For every 4000 Litres you need to Change Gk1 & Gk2 filters cost: 1650 and 3750+ installation charges extra.
Bought it few months ago. Now thinking of selling it on olx and planning to buy AQUA Guard or Kent.
Pls R&D before you buy this. Its like 6000 Yearly instalment to Hindustan Liver, almost 50% of actual cost
