There are couple of water purifiers in Bangalore market. I was reading and interacting most popular brands i.e. zero b, Kent etc. but I found in various websites and customer response was very positive on Pureit. I built a softener plant in terrace from zero B, and now I bought Pureit - Ultima model. I am really happy with filter water and taste is really good. I use the bore-well water.
I would positively recommend for pureit Ultima model. Still I dont have idea for other models. lets wait for their customer service experience.
