About 2 years back, we used to drink normal tap water which tasted really bad sometimes that we couldn't get a way to quench our thirst. To overcome this, I bought this product from a local retailer near my house around a year back. Since then, the water taste and overall quality has considerably improved and we all now feel much more refreshed and healthy. The storage capacity of 7 liters adds to its charm supported by nominal electricity consumption. I will highly recommend this buy to all those who're facing the same issue, so that even they feel amazed and ecstatic with its mind blowing performance. Santosh Bajaj Jaipur
