I was live in kolkata. As you know no water problem in kolkata. I was using a local brand water purifier. But problem arised when I shifted in Mumbai.
Water become more salty. Some of my neighbor advice me to use kent ro pride water purifier. Because all are my neighbors are using kent ro pride water purifier. Kent Ro pride purifier is a most cost effective. Technically also very good. My all family members are using this.Even my 2 yrs old baby can drink water directly. So its really pure.
